App freezes when modal view controller is disabled on iPad

This works on iPhone BTW (both iOS 5.1)

My application freezes when I call [self dismissModalViewControllerAnimated:NO];

I've tried many different approaches:

My code is as I have it now:

-(void) doneEditing:(NSString *)value
{
    [multiLineText dismissModalViewControllerAnimated:NO];
    self.currentActiveTextView.text = value;
    self.currentActiveTextView = nil;
}

- (void)textViewDidBeginEditing:(UITextView *)textView
{
    multiLineText = [[MultilineTextViewController alloc] init];
    multiLineText.delegate = self;
    multiLineText.text = textView.text;
    self.currentActiveTextView = textView;
    [self presentModalViewController:multiLineText animated:NO];
}

MultilineTextViewController.h

@protocol DoneEditing
    -(void)doneEditing:(NSString*)value;
@end

@interface MultilineTextViewController : UIViewController
{
    UITextView *inputText;
    id<DoneEditing> delegate;
}
@property (nonatomic, strong) NSString *text;
@property (nonatomic, strong) id<DoneEditing> delegate;
@end

Function called with the made button

-(void) done:(id)sender
{
    [delegate doneEditing:inputText.text];
}

I tried to dismiss modality in my executed function I tried this in both places on my own I also tried this in MultilineTextViewController 

if ([[self parentViewController] respondsToSelector:@selector(dismissModalViewControllerAnimated:)]){

    [[self parentViewController] dismissModalViewControllerAnimated:NO];

} else {

    [[self presentingViewController] dismissViewControllerAnimated:NO completion:nil];
}

Just some history, when the user clicks on a button UITextView

that I use to open a new ModalViewController

one to allow the user more room to enter large amounts of text, after the user is finished clicking and I call the delegate method, put the text in the original form.

If I change animated to yes in any of the above cases it still doesn't work, but instead of freezing, I get NSInternalInconsistencyException 

Attempting to begin a modal transition from <WorkflowViewController: 0xc6846b0> to <MultilineTextViewController: 0xc64b960> while a transition is already in progress. Wait for viewDidAppear/viewDidDisappear to know the current transition has completed

Any ideas?

I can't seem to find a reason for this thing not to work ...

Since its an iPad, perhaps you can use UIPopOverController whenever you want to present a view. Try to create a UIPopOverController by initializing it with a view controller for your modal view. You can set the size and location from which it will appear. You can set the class it is called from to be a delegate for the view so you can receive notifications.



Hope it helps

Try the following:



[self dismissModalViewControllerAnimated:NO];

Try to check how many times Editing has been executed. with NSLog there.

Edit:

Try adding a delay before disabling modalViewController:

[self performSelector:@selector(dismiss) withObject:nil afterDelay:1.0];

- (void)dismiss {
    [self dismissModalViewControllerAnimated:NO];
}

Make sure your text view has properly evaded first responder status prior to deviating from the screen.

Something like: [inputText resignFirstResponder];

try it

[multiLineText popViewControllerAnimated: YES];

I don't understand your line

[multiLineText dismissModalViewControllerAnimated:NO];

since multiLineText is your modal view controller firing must be called by the view controller representing it, i.e. in your first example (since you assigned a delegate to the view of the view controller)

[multiLineText.delegate dismissModalViewControllerAnimated:NO];

must work. You are setting the delegate to zero to avoid getting fired twice.

In recent iOS versions, you can send the message rejectModalViewControllerAnimated: to the most modal one.

Apple has been manipulating how this works lately. Try submitting the modal itself.
