dismissViewControllerAnimated crash in iOS8

问题:

I have a application that work very well in iOS7.0/7.1 Since the last iOS update (8.0) the dismissViewControllerAnimated crash every time. Someone saw the same thing ?
I have a control this to call the second controller:

**detailViewController.delegate = self;
[self presentViewController:detailViewController animated:YES completion:nil];**

and in the close button I use this:

**// Do something with the sender if needed
[viewController dismissViewControllerAnimated:YES completion:NULL];**

I Used this (Remove view controller from another view controller) as a guide for implementation the "second" control but the crash appear again.

Any ideas ?

回答1:

I had a very similar issue when I was dismissing programmatically. (like when a delegate finished a process).

I used this and it worked perfectly:

if (![self isBeingDismissed]) {
    [self dismissViewControllerAnimated:YES completion:^{
    }];
}

It simply checks to see if it was already in the process of being dismissed. Hope this works for you!

Check if there is any dealloc function defined as mentioned below. As it might led to Crash Sometimes.

- (void)dealloc {
      [_yourview release]; //don't do this
      [super dealloc];
}
