I was wondering if there was a way to have the user create/delete cells in a Table View but when they click on it, every cell that they create loads the same view. I have the first part created but I cannot seem to get it to load a view.
Simple create a new view and push on didSelectRowAtIndexPath Delegate method of UITableView.
For ex.
- (void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath{
DetailViewController *vController = [[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil];
[self.navigationController pushViewController:vController animated:YES];
[vController release];
}

Maybe a silly question. But I've added a navigation item in code in my view controller:
//Set add transactions button
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(addButtonAction:)];
[self.navigationItem setRightBarButtonItem:addButton];
-(void)addButtonAction
{
}
And I want to segue from this navigation item directly to a new view controller. However I cannot create any segue from the previous view controller to the next one. And since my navigation item is created in code I cannot "pull" a segue from there to a new VC. How can I do that?
Do this
-(void)addButtonAction
{
MyNewViewController *myNewVC = [[MyNewViewController alloc] init];
// do any setup you need for myNewVC
//If you want to present modal
[self presentModalViewController:myNewVC animated:YES];
//If you want to push
[self.navigationController pushViewController:myNewVC animated:YES];
}
Add button to dismiss if presented using modal. In case of push it will have back button
I am having of one CustomView in one xib and two different views in two different xib's.
I want to display those two view one after the other in one single CustomeView.
I have an object of NSView which is connected to CustomView in .xib file
#property (retain) IBOutlet NSView *mySubview;
#property (retain) NSViewController *viewController;
Method to open one View is:
-(IBAction)selectBookTicket:(id)sender
{
//setting status label to nil
_viewController=[[NSViewController alloc] initWithNibName:#"BookTicket" bundle:nil];
//loading bookTicket xib in custom view of NormalUserWindow
[_mySubview addSubview:[_viewController view]];
}
Method to open another view in same CustomView is:
-(IBAction)selectTicketCancellation:(id)sender
{
_viewController=[[NSViewController alloc] initWithNibName:#"CancelTicket" bundle:nil];
//loading CancelTicket xib in custom view of NormalUserWindow
[_mySubview addSubview:[_viewController view]];
}
When I am opening any view for first time its displaying properly in CustomView, but when I am trying to open second view or same view for second time then its get overlapping on previous opened view.
I tried
[_mySubview removeFromSuperview]
It's removing 'mySubview' completely, I mean what ever the view is currently loaded it is get removing but it's not allowing to display any views after that '[_mySubview removeFromSuperview]' get executed.
You must remove only the view that you have added from the view controller. Try the following code instead.
-(IBAction)selectTicketCancellation:(id)sender
{
[[_viewController view] removeFromSuperView];
_viewController=[[NSViewController alloc] initWithNibName:#"CancelTicket" bundle:nil];
//loading CancelTicket xib in custom view of NormalUserWindow
[_mySubview addSubview:[_viewController view]];
}
Executing [_mySubview removeFromSuperview] will remove your host view (i.e; the one that is displaying views from other view controllers) from view hierarchy and this explains the "not allowing to display any other subviews part".
I am using Xcode 4.5.2.I have created a customization tableview programmatically.When i click on a row I need to move to next view.Is there a way to do this?.
Please use the below code to move into another view controller while tapping on table view cell.
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Navigation logic may go here. Create and push another view controller.
/*
<#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:#"<#Nib name#>" bundle:nil];
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
*/
}
I have about ten IBActions on my main view that go to the same modal view and I need to know how to see what IBActon was pressed to get there and put that in a NSString on the modal view.
Here's the code that sends you to the modal view. The only difference in the IBActions is the name. Like playMovie: and playMovie2: and so on.
-(IBAction)playMovie:(id)sender{
VideoSubViewController *subView = [[[VideoSubViewController alloc] init] autorelease];
[subView setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentModalViewController:subView animated:YES];}
You could create an init* on the modal view that takes that information. The usage would be:
VideoSubViewController *subView =
[[[VideoSubViewController alloc] initForAction:#"playMovie"] autorelease];
You then store that information in the view instance in order to use it.
I have Table View controller, then it has subclass DetailViewController, which content changes depending on cell chosen, but when move on, and from my DetailViewController go to MapView, I try to use same method I used to get text on DetailViewController, but it dont works, no matter what I do. Im stuck with it more like 3 week now:(
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (!self.detailViewController) {
self.detailViewController = [[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil];
[self.navigationController pushViewController:self.detailViewController animated:YES];
[self.detailViewController changeProductText:[teksti objectAtIndex:indexPath.row]];
[self.detailViewController changeProductText1:[adrese objectAtIndex:indexPath.row]];
[self.detailViewController changeProductText2:[laimigastunda objectAtIndex:indexPath.row]];
[self.detailViewController changeImage:[imageChange objectAtIndex:indexPath.row]];
}
}
No matter what I change here, it dont work.
It looks from the code you are showing that you are not giving a data object to your detailViewController, but rather set directly the values.
This is not the way to do it and probably the reason why you are having issues. You need to grasp the concept of MVC and go back to it.
At least you should
1. build a dictionary in first view with keys #"teksti", #"adrese", #"longitude", #latitude".
2. Create a property in DetailViewController to hold the dictionary.
3. update the values displayed when displaying the DetailViewController
So that when you press the map button, you can then push a view containing a mapView and set the map to the latitude and longitude that you have.
So it would do:
NSDictionary *dict = [[NSDictionary alloc] initWithObjectsAndKeys:[teksti objectAtIndex:indexPath.row], #"teksti", [adrese objectAtIndex:indexPath.row], #"adrese", [latitude objectAtIndex:indexPath.row], #"latitude", [longitudes objectAtIndex:indexPath.row], #"longitude", nil];
[detailViewController setDict:dict];
and in the DetailViewController.m:
- (void)viewWillAppear:(BOOL)animated{
[self changeProductText:[dict objectForKey:#"teksti"]];
.... And so on
}
Your code will be useful to provide you with more details directions.
