I have some issues in Today Extensions on iOS8. I tried debugging using the Xcode Debugger and by putting nslogs. There is no logic in my code as well. For some reason:
The widget is not displaying any data (its only working for Hello World Label)
Debugging is not working, it doesn't reach any break points. Is there any specific way to debug extensions?
Here is my code snippet
#implementation TodayViewController{
NSArray *localList;
}
-(void)awakeFromNib{
[super awakeFromNib];
[self loadList];
[self setPreferredContentSize:self.tableView.frame.size];
NSLog(#"inside awake from nib");
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
NSLog(#"inside view did load");
}
-(void)loadList{
NSMutableArray *mutableArray = [[NSMutableArray alloc]initWithCapacity:5];
[mutableArray addObject:#"asdjasdj"];
[mutableArray addObject:#"qowiepqiw"];
[mutableArray addObject:#"qoqwoei"];
[mutableArray addObject:#"pqoiweoqi"];
[mutableArray addObject:#"lkdsflk"];
[mutableArray addObject:#"kdjlkaj"];
localList = [mutableArray copy];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [localList count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"WidgetCell"];
UILabel *label = [[UILabel alloc]init];
[label setText:[localList objectAtIndex:indexPath.row ]];
[[cell contentView]addSubview:label];
return cell;
}
Write this
[self setPreferredContentSize:self.tableView.frame.size];
before loading any subview (tableview or label), and I write these in viewDidLoad. It works for me.
If the widget is not displaying, you can also try rebooting the phone.
To debug the extension, you need to manually attach the widget to the debugger.
From the Xcode menu "Debug" -> "Attach to process" -> "your extension bundle id"
Also make sure that the phone is unlocked if you're running it on a device. At least for me running the widget target won't unlock the phone but it works just fine if I do it myself.

So I switched from a UITableView to a UICollectionView. The cells are all loading just fine and look beautiful, but now I can no longer select any of them. The taps are recognized in the logs, but it doesn't take me to the view that it's supposed to take me to anymore.
The only things that changed really are the ones the ones you see commented out in the "cellForItem" section. Everything else is identical to how it was when it was working in the TableView. It's just supposed to take me to the ViewController specified when you tap. Instead the tap is recorded, but it does nothing. Any help would be appreciated.
Also I tried getting rid of the [collectionView deselectItemAtIndexPath:indexPath animated:YES];
...but it didn't make any difference.
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
PlaceCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:reuseIdentifier forIndexPath:indexPath];
// Configure the cell
//UINib * placeCell = [UINib nibWithNibName:#"Shops" bundle:nil];
// NSArray *topLevelItems = [placeCell instantiateWithOwner:self options:nil];
// cell = [topLevelItems objectAtIndex:0];
Place *p = [_entries objectAtIndex:indexPath.row];
cell.placeName.text = p.PName;
NSLog(#"p:%#",p.PName);
cell.placeName.textColor = [UIColor colorWithRed:3/255.0f green:6/255.0f blue:4/255.0f alpha:1.0f];
NSString *pIcon;
pIcon = typeName;
//NSLog(pIcon);
cell.placeImg.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:p.PImage]]];
NSLog(#"i:%#",p.PImage);
return cell;
}
-(void) collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath{
NSLog(#"Tap Recognized");
[collectionView deselectItemAtIndexPath:indexPath animated:YES];
Place *p = [_entries objectAtIndex:indexPath.row];
DetailPlaceViewController * pvc = [[DetailPlaceViewController alloc] init];
[pvc setPlace:p];
[self.navigationController pushViewController:pvc animated:YES];
}
Well this one was fun...
For some odd reason my navigation controller isn't working... so of course using the navigation controller to load a view wasn't going to work. Simple enough solution... load the view without the navigation controller. I was just going to delete this question, but maybe somebody might be in a similar situation one day:
[self presentViewController:pvc animated:YES completion:nil];
In my app I am trying to navigate to a new View from a TableViewCell, But i dont know how. Could you help guys? I am using Xcode 4.6. and .xib, no storyboard. I am very new to coding so please explain it as simple as possible! Here is what i have tried, please correct me:
- (void)viewDidLoad
{
tableData = [[NSArray alloc] initWithObjects:#"aaoversikt1", #"Paul", #"George", #"Ringo", nil];
[super viewDidLoad];
UILabel *nav_title1 = [[UILabel alloc] initWithFrame:CGRectMake(60, 10, 220, 25)];
nav_title1.font = [UIFont fontWithName:#"Arial-BoldMT" size:18];
nav_title1.textColor = [UIColor whiteColor];
nav_title1.adjustsFontSizeToFitWidth = NO;
nav_title1.textAlignment = NSTextAlignmentCenter;
nav_title1.text = #"Ålesund";
nav_title1.backgroundColor = [UIColor clearColor];
self.navigationItem.titleView = nav_title1;
}
#pragma mark - TableView Data Source methods
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection: (NSInteger)section;
{
return [tableData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
UITableViewCell *cell = nil;
static NSString *CellIdentifier = #"Cell";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
#pragma mark - TableView Delegate methods
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
AAOversiktViewController *aaoversikt1 = [[AAOversiktViewController alloc] initWithNibName:#"AAOversiktViewController" bundle:nil];
[self.navigationController pushViewController:aaoversikt1 animated:YES];
}
Thank You!
From first glance I would say that the problem lies within your [self.navigationController pushViewController] method. Have you initiated a navigation controller in your app either in the app delegate or root view controller?
If not i would recommend:
[self presentViewController:aaoversik1 animated:YES completion:NULL];
If you are wanting to push through the navigation stack so that you have a back button then I would look at implementing a UINaviationController.
Otherwise you can create a custom back button and use the same method in this post to present the root view controller (not totally recomended as using UINavigationController is much cleaner).
Let me know if this has been of any help, T
I have been looking until 6 o'clock this morning, but I can't figure out why the didSelectRowAtIndexPath method is not being called. I am getting quite desparate on this one.
The tableview is shown properly, but I cannot succeed to enable the selection of a cell.
In the header file , I added:
#interface AlertsTable : UIViewController<UITableViewDelegate, UITableViewDataSource, CMPopTipViewDelegate>{
UITableView *TableView;
}
#property (nonatomic, retain) UITableView *TableView;
In the implementation file:
#synthesize TableView;
- (void)viewDidLoad
{
[super viewDidLoad];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
//Set the title
//Format Alerts table
//self.view.backgroundColor = [UIColor redColor];
CGFloat sideMargin = 10;
CGFloat topBottomMargin = 44;
CGFloat originX = sideMargin;
// compute width based on view size
CGFloat sizeWidth = (self.view.bounds.size.width - (sideMargin * 2));
CGFloat originY = topBottomMargin;
// compute height based on view size
CGFloat sizeHeight = (self.view.bounds.size.height - (topBottomMargin * 2));
//self.view.frame = CGRectMake(originX, originY, sizeWidth, sizeHeight);
self.TableView = [[UITableView alloc] initWithFrame:CGRectMake(originX, originY, sizeWidth, sizeHeight) style:UITableViewStylePlain];
//Initialize the array.
AlertsItems = [[NSMutableArray alloc] initWithObjects: #"Alert 1", #"Alert 2", #"Alert 3" , #"Alert 4", #"Alert 5", #"Alert 6", nil];
[self.TableView setDelegate:self];
[self.TableView setDataSource:self];
[self.view addSubview:TableView];
TableView.userInteractionEnabled = YES;
TableView.allowsSelection = YES;
TableView.allowsSelectionDuringEditing = YES;
NSLog(#"delegate:%# dataSource:%#", self.TableView.delegate, self.TableView.dataSource);
}
The delegate and datasource are both not nil on the check.
Note that the "Alertstable" inherits from a UIViewController, not a UITableViewController.
This is necessary due to the implementation I chose: the tableview is shown on a popupwindow shown on the screen (using another class that I took from the internet).
This is the didSelectRowAtIndexPath method:
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *alertString = [NSString stringWithFormat:#"Clicked on row #%d", [indexPath row]];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:alertString message:#"" delegate:self cancelButtonTitle:#"Done" otherButtonTitles:nil];
[alert show];
}
The methods:
[super touchesBegan:...];
[super touchesEnded:...];
[super touchesMoved:...];
are not implemented.
I added the AlertTable from another ViewController
AlertsTable *AlertTable = [[AlertsTable alloc] WithButton:sender withArray:self.PopTipViews];
[self.view addSubview:AlertTable.view];
I also implemented:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Set up the cell...
[[cell textLabel] setText:[AlertsItems objectAtIndex:indexPath.row]];
NSLog (#"%#",[AlertsItems objectAtIndex:indexPath.row]);
return cell;
}
Do you have any idea what the problem could be?
I'm not very experienced in Xcode and I'm really stuck.
Edit:
I know that it is not custom, but the link to the project can be found here (perhaps I'm overlooking something:
https://www.bilbu.be/BarConnect_v2.zip
The LoginViewController.xib is not properly linked (it is available in the en.lproj subfolder) so you may need to link first (I noticed too late and I had the file uploaded by a friend before - I cannot re-upload it myself unfortunately).
ViewController VC class calls the AlertsTable VC class. There is more in the project that I suppose you can ignore...
Note that the purpose of this project is only to serve as visual interface prototype. It is not meant to be the best optimized application (this is what other developers will do). If this doesn't work, I will use Photoshop to create the interfaces, but I guess that's not gonna be as convincing...
I successfully compiled your project. The problem is that you're going against the MVC pattern. The controller (AlertsTable) is inside of a view (CMPopTipView). I'd suggest you to rethink the hierarchy of the controllers and views. Hope this will help you.
Try changing
TableView.userInteractionEnabled = YES;
TableView.allowsSelection = YES;
TableView.allowsSelectionDuringEditing = YES;
to
self.TableView.userInteractionEnabled = YES;
self.TableView.allowsSelection = YES;
self.TableView.allowsSelectionDuringEditing = YES;
and are you allocating self.TableView? Something like...
self.TableView = [[UITableView alloc] init];//[[UITableView alloc] initWithStyle:UITableViewStylePlain];
I have an rss parser as part of my app code, and it is working fine and loading the rss xml file and populating the tableview fine.
The problem is with a refresh/reload button, which does reload the rss data, but it APPENDS the new data to the table and the table just grows and grows in size.
What the behaviour should do is to clear the old table data and rebuild the table with the new data - so that the table always shows just ONE set of data and doesn't keep growing every time the reload/refresh is pressed.
The table build code is as follows:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
cell.textLabel.text = [[stories objectAtIndex: storyIndex] objectForKey: #"date"];
cell.detailTextLabel.text = [[stories objectAtIndex: storyIndex] objectForKey: #"title"];
[cell.textLabel setLineBreakMode:UILineBreakModeWordWrap];
[cell.textLabel setNumberOfLines:0];
[cell.textLabel sizeToFit];
[cell.detailTextLabel setLineBreakMode:UILineBreakModeWordWrap];
[cell.detailTextLabel setNumberOfLines:0];
[cell.detailTextLabel sizeToFit];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
And the reload/refresh button code is:
- (void)reloadRss {
UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0, 0, 20, 20)];
UIBarButtonItem * barButton = [[UIBarButtonItem alloc] initWithCustomView:activityIndicator];
[[self navigationItem] setLeftBarButtonItem:barButton];
[barButton release];
[activityIndicator release];
[activityIndicator startAnimating];
[self performSelector:#selector(parseXMLFileAtURL) withObject:nil afterDelay:0];
[newsTable reloadData];
}
I have tried to solve this by adding the line:
if (stories) { [stories removeAllObjects]; }
to the reload section, which I think should work and does clear the table, but the app then crashes the app with an EXC_BAD_ACCESS.
Any ideas or suggestions greatly appreciated!
Actually, have now solved this!
Was due to "autoreleasing" elements of the array, so after clearing this out, they were invalid.
Removing autorelease and just releasing these objects in the final dealloc worked.
The Code EXC_BAD_ACCESS does mean, that you want connect at a variable that does not exists anymore.
In your code example, I can see, the problem to see at the following two lines of code:
[activityIndicator release];
[activityIndicator startAnimating];
You release the activityIdicator befor starting the Animating.
Try to release at the end of the function.
[activityIndicator startAnimating];
[self performSelector:#selector(parseXMLFileAtURL) withObject:nil afterDelay:0];
[newsTable reloadData];
[activityIndicator release];
How to change it back from activity indicator to disclosure ??
the problem is:
When i didSelectRow, i made disclosure to activity indicator because it will load some picture for the next view controller and It's worked, but i dont have any luck to change it back to disclosure after pushViewController. i already tried to reload the table from the 2ndViewController but it's crashed.
So anybody have a solution for this problem..
Thanks in advance
This is my code in didSelectRow :
-(void)threadStartAnimating:(id)data
{
[activityView startAnimating];
[self.navigationController pushViewController:bdvController animated:YES];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
[cell setAccessoryView:activityView];
[NSThread detachNewThreadSelector:#selector(threadStartAnimating:) toTarget:self withObject:nil];
// Navigation logic -- create and push a new view controller
if(bdvController == nil)
bdvController = [[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:[NSBundle mainBundle]];
AppRecord *appRecord = [self.entries objectAtIndex:indexPath.row];
bdvController.appsRecord = appRecord;
bdvController.HeaderText.text = appRecord.appName;
bdvController.title = appRecord.artist;
[bdvController.tableView reloadData];
}
The best way is to set pointer nil to the accessoryView, example:
cell.accessoryView = nil;
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
cell.selectionStyle = UITableViewCellSelectionStyleGray;
In my code these operations work fine.
