I am unable to show just simple UIActionSheet in my application in IOS8 on real device

Question

When I run this in IOS 8 I get NSRangeException exception

UIActionSheet *uias = [[UIActionSheet alloc] initWithTitle:@"Test"
                                                      delegate:self
                                             cancelButtonTitle:@"Test"
                                        destructiveButtonTitle:@"Test"
                                             otherButtonTitles:@"Test", nil];

[uias showInView:self.view];

Exception from output:

In IOS7 and even in simulator IOS 8 everything works, just on real device in IOS8 it crashes...

It looks like in my complex application on wich I wokr for 3 years also all UIAlertView are crashing with same exception, i tried to test new UIAlertController and have same exception. So my conclusion is that some configuration of my application is causing problem to UIAlertController what is actually what UIAlertView and UIActionSheet are using in ios 8.

Answer 1

OK, this was my fault but I don't understand why this caused so hard to tackle problem just under this special circumstances IOS8 and build running on device and ...

So this code caused problem...

@implementation NSMutableArray (Extension)

- (void)setObject:(id)thing atIndexedSubscript:(NSInteger)index {
    [self replaceObjectAtIndex:index withObject:thing];
}
