Dismissing a modal view causes the app crash

I\'m displaying a modal view called \"rule\" from a round rect button. In that \"rule\" modal view i\'m displaying another modal view called \"newRule\" when user clicks the Create Rule button.

I'm displaying a modal view called "rule" from a round rect button. In that "rule" modal view i'm displaying another modal view called "newRule" when user clicks the Create Rule button. When i'm quitting from the "newRule" modal view the app crashes. Here's the code i had written for quitting the "newRule" modal view.

     [self dismissModalViewControllerAnimated:YES];

Nothing is displayed in the console. When i tried to debug the code, it displayed a EXC_BAD_ACCESS after the dealloc method. My dealloc method looks like this:

    [label release];
    label = nil;

    [imageArray release];
    imageArray = nil;

    [languageElementsArray release];
    languageElementsArray = nil;开发者_如何学JAVA
    [super dealloc];

Please help me.


Is the label a UILabel object? Also what are in the arrays? Views are automatically released once their superview is released, so releasing a subview after its superview has been released (or releasing the subview then the superview) will cause an crash similar to the one you describe


I'm experiencing something similar. When I comment out the last line ( [super dealloc] ), it then works. Does this make a difference for you?


If you happen to be using Automatic Reference Counting in Xcode 4.2, then you should not have a [super dealloc] at all—which would result in this error.

Of course, in that context you likely should not be releasing these other objects either.
