I have a page with multiple popovers that I am trying to dismiss when another popover appears I am using the following code but it doesn't seem to dismiss the popover
-(IBAction)OISButton:(id)sender{
if(![popoverController isPopoverVisible]){
OISView *oisView = [[OISView alloc] init];
UIPopoverController *pop = [[UIPopoverController alloc] initWithContentViewController:oisView];
[pop setDelegate:self];
[pop presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[pop setPopoverContentSize:CGSizeMake(320, 460)];
[oisView release];
}
else{
// close popover
[popoverController dismissPopoverAnimated:YES];
}
}
Any suggestions on how to modify this code? Thanks
You're not assigning to popoverController, which might explain the problems you're having.
Thanks Tom for putting me in the right direction, I have included the code below for one popover with a view called OISView in a format to handle multiple popovers:
-(IBAction)OISButton:(id)sender{
if([popoverController isPopoverVisible]){
[popoverController dismissPopoverAnimated:YES];
} else
{
OISView *oisView = [[OISView alloc] init];
UIPopoverController *pop = [[UIPopoverController alloc] initWithContentViewController:oisView];
self.popoverController = pop;
[pop setDelegate:self];
[pop presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[pop setPopoverContentSize:CGSizeMake(320, 460)];
[oisView release];
}
}

I am using the following code to show an Activity Indicator while some data is loading. The problem is that when I try to hide it again. The Activity Indicator stays put. The screen lightens a bit but that is it.
To show it:
self.overlayView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.overlayView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.3];
self.activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
self.activityIndicator.center = self.overlayView.center;
[self.overlayView addSubview:self.activityIndicator];
[self.activityIndicator startAnimating];
[self.tableView addSubview:self.overlayView];
To hide it:
[self.activityIndicator stopAnimating];
[self.overlayView removeFromSuperview];
Try to add your overlayView to the superview of your tableView :
[self.view.superview addSubview:self.overlayView];
I figured it out with a combination of stackoverflow questions. Here is my code to show the UIActivityIndicatorView
-(void)loadView {
[super loadView];
self.overlayView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.overlayView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.3];
self.activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
self.activityIndicator.center = self.overlayView.center;
[self.overlayView addSubview:self.activityIndicator];
[self.tableView addSubview:self.overlayView];
[self.activityIndicator startAnimating];
}
Here is the code to hide it. It looks like putting the code in the loadView event made all the difference.
[overlayView removeFromSuperview];
I am trying to make an actionsheet for another button but I get two errors: "No visible #interface for 'UIstoryboard' declares the selector 'InitiateViewControll:' and, "No visible #interface for SWViewController' declares the selector 'presentViewController:animated:' I was giving this code so is there any names that I need to name in this to make this code costomized for my code? I am trying to learn i am a noob sorry :( here is the code I have so far:
- (IBAction)OpenActionSheetButton:(id)sender {
UIActionSheet *actionsheet = [[UIActionSheet alloc]initWithTitle:#"There is no going back, are you sure???" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:#"Continue" otherButtonTitles:nil, nil];
[actionsheet showInView:self.view];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0) {
UIViewController *controller = [self.storyboard instantiateViewControll:#"storyboardViewName"];
//Push
[self.navigationController pushViewController:controller animated:YES];
//Modal
[self presentViewController:controller animated:YES];
}
}
Please help guys?
Try out this code..And SWViewController must have a Navigation Controller
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex == 0)
{
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"storyboardViewIdentifier"];
//storyboardViewIdentifier is the ViewController identifier you specify in the storyboard
//PUSH
[self.navigationController pushViewController:controller animated:YES];
//Modal
[self presentViewController:controller animated:YES completion:Nil];
}
}
Try this. It works for me:
if(buttonIndex == 0)
{
NSString * storyboardName = #"Main";
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
Paypal_ViewController * vc = [storyboard instantiateViewControllerWithIdentifier:#"Paypal_ViewController"];
[self presentViewController:vc animated:YES completion:nil];
}
I have a custom UIPickerView that is embedded into an UIActionsheet that comes up half the screen when called. Works great. The problem is that I want to have the barrelPicker be showing the 'most probable' results as the selection when it first comes up (after all the data has been loaded into it).
Prior to having the custom picker embedded in the action sheet, I had it in a UIViewController and was just calling "showProbableResults" (a custom method of mine) in the viewDidLoad method of the ViewController, because I knew at that point, the UIPickerView would be loaded up and ready to go. Is there an equivalent place for me to call this method now or do I need to rethink my whole design? Essentially, what I need is a place to call this after the UIPickerView has been loaded.
- (void)startWithDelegate:(UIViewController <ImageProcessingDelegate> *)sender
{
self.delegate = sender;
self.showFirstBottle = YES;
[self start];
}
- (void) start {
self.actionSheet = [[UIActionSheet alloc] initWithTitle:#"Choose Something"
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[self.actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
NSLog(#"1.) About to alloc the picker");
self.vintagePicker = [[UIPickerView alloc] initWithFrame:pickerFrame];
self.vintagePicker.showsSelectionIndicator = YES;
self.vintagePicker.dataSource = self;
self.vintagePicker.delegate = self;
[self.actionSheet addSubview:self.vintagePicker];
[self.vintagePicker release];
UISegmentedControl *nextButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:#"Next"]];
nextButton.momentary = YES;
nextButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
nextButton.segmentedControlStyle = UISegmentedControlStyleBar;
nextButton.tintColor = [UIColor blackColor];
[nextButton addTarget:self action:#selector(show:) forControlEvents:UIControlEventValueChanged];
[self.actionSheet addSubview:nextButton];
[nextButton release];
UISegmentedControl *backButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:#"Back"]];
backButton.momentary = YES;
backButton.frame = CGRectMake(10, 7.0f, 50.0f, 30.0f);
backButton.segmentedControlStyle = UISegmentedControlStyleBar;
backButton.tintColor = [UIColor blackColor];
[backButton addTarget:self action:#selector(cancel:) forControlEvents:UIControlEventValueChanged];
[self.actionSheet addSubview:backButton];
[backButton release];
[self.actionSheet showInView:_delegate.parentViewController.tabBarController.view]; // show from our table view (pops up in the middle of the table)
[self.actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
}
One option is to create a reusable picker view, as shown here, and then call the #optional
-(void)setInitialPickerValueToRow:(int)i inComponent:(int)j animated:(BOOL)k{
[pickerView selectRow:i inComponent:j animated:k];
}
from any view controller or NSObject (such as your UIActionSheetDelegate).
Your other option is to set a standard pre-chosen selection, as follows:
self.vintagePicker = [[UIPickerView alloc] initWithFrame:pickerFrame];
self.vintagePicker.showsSelectionIndicator = YES;
self.vintagePicker.dataSource = self;
self.vintagePicker.delegate = self;
[self.actionSheet addSubview:self.vintagePicker];
[self.vintagePicker selectRow:0 inComponent:0 animated:NO];
You could also have different variables that you set, and have selectRow:inComponent:animated: access those, instead of being preset.
[self.vintagePicker selectRow:myRow inComponent:0 animated:NO];
Hope this helps!
i wanted to display the detail view after tapping the right button on the annotation of mapview in xcode but i could not get the view to display ,
my code:
- (void)showDetails:(id)sender
{
[self.navigationController setToolbarHidden:YES animated:NO];
[self.navigationController pushViewController:self.detailViewController animated:YES];
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
static NSString* BridgeAnnotationIdentifier = #"bridgeAnnotationIdentifier";
MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:BridgeAnnotationIdentifier] autorelease];
customPinView.pinColor = MKPinAnnotationColorPurple;
customPinView.animatesDrop = YES;
customPinView.canShowCallout = YES;
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
NSLog(#"%#",rightButton);
[rightButton addTarget:self
action:#selector(showDetails:)
forControlEvents:UIControlEventTouchUpInside];
customPinView.rightCalloutAccessoryView = rightButton;
return customPinView;//[kml viewForAnnotation:annotation];
}
The showDetails method gets called but cannot push the detailViewController to the top ,
[self.navigationController pushViewController:self.detailViewController animated:YES];
this code should have pushed detail view to the top and displayed the detailView but it does not please ,
any help would be greatly appreciated , what i wanted to do is when anybody taps on the right button of annotation on the mapview ,i wanted to display a detail view , thanking you in advance..
There is no target/action required, there is a delegate method that gets called when the callout accessory view is tapped: mapView:annotationView:calloutAccessoryControlTapped:
Thank you , for your help i am able to open the detailViewController by changing my showDetails method
- (void)showDetails:(id)sender
{
detailViewController *dvController = [[detailViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:dvController animated:YES];
[dvController release];
dvController = nil;
}
I need to stick a toolBar with a UITextField inside to a keyboard.
What if I make the whole toolBar (which I think is the textField's super view) the inputAccessoryView of its textField?
I mean like this:
textField.inputAccessoryView = toolBar; // textField is inside the toolBar
I've been trying on this but I have not made it work yet.
Anyone can help?
Or is there another way to achieve what I want?
- (void)viewDidLoad
{
[self createAccessoryView];
[textField setDelegate:self];
[textField setKeyboardType:UIKeyboardTypeDefault];
[textField setInputAccessoryView:fieldAccessoryView];
}
- (void)createAccessoryView
{
CGRect frame = CGRectMake(0.0, self.view.bounds.size.height, self.view.bounds.size.width, 44.0);
fieldAccessoryView = [[UIToolbar alloc] initWithFrame:frame];
fieldAccessoryView.barStyle = UIBarStyleBlackOpaque;
fieldAccessoryView.tag = 200;
[fieldAccessoryView setBarStyle:UIBarStyleBlack];
UIBarButtonItem *spaceButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(done:)];
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:NSLocalizedString(#"Previous", #""), NSLocalizedString(#"Next", #""), nil]];
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
[segmentedControl setMomentary:YES];
UIBarButtonItem *segmentButton = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[fieldAccessoryView setItems:[NSArray arrayWithObjects:segmentButton, spaceButton, doneButton, nil] animated:NO];
[segmentButton release];
[spaceButton release];
[doneButton release];
[segmentedControl release];
}
When are you setting the property? You may be setting it after the view has already loaded.
Try setting it in
- (void) viewDidLoad
