The iphone application crashes without any console errors or crash logs:

Question

I'm new here. I am trying to create a quiz application, and while my application works fine for the first iteration of the quiz, it exits without any console errors in the second run. PAsting all the code below for reference.

It seems that when I run the quiz again - (void) loadNextWord, the function below executes, but nothing happens after that.

Please, help!

Thank!

Debugger dump:

My line 14 in the main function is int retVal = UIApplicationMain (argc, argv, nil, nil);

#import <UIKit/UIKit.h>

 int main(int argc, char *argv[]) {

NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, nil);
[pool release];
return retVal;
}

Program received signal:  "EXC_BAD_ACCESS".

Answer 1

Looking at the stack trace, you will see a line

[NSAutoreleasePool release]

, , :

NSString *string = [NSString stringWithString:@"Hello"]; // This string is autoreleased
[string release]; // This line won't crash but is WRONG!

, . , , - . , .

, , - :)

, nessasary. , wordImageView . . , -

self.wordImageView = nextImageView;
[nextImageView release];

[wordImageView release]; // release the flagView memory
wordImageView = nextImageView; // reassign flagView to the new view

, .

Btw, , , , . , , .
