UIAlertView Delegate method not called in UITextView Class

I'm tying to call didDismissWithButtonIndex on UITextView Class ,but it not called. I also implement UIAlertViewDelegate on MyViewcontroller.h file and [alert setDelegate:self] to method.

So is that possible to call UIAlertView Delegate method in UITextView Class ??

+ (void)deleteTextr:(UITapGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer.state == UIGestureRecognizerStateBegan)
    {
        UIAlertView *alert  = [[UIAlertView alloc]initWithTitle:@"" message:@"Delete Text !!!!" delegate:self cancelButtonTitle:@"Delete" otherButtonTitles:@"No", nil];
        [alert setDelegate:self];
        [alert show];
    }
}
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    if(buttonIndex == 1)
    {
        [self removeFromSuperview];
    }
}

deleteTextr: is a class method. In the context of a class method, self is just a reference to the class. To use the UIAlertViewDelegate protocol, you need assign an instance of a class to the UIAlertView instance's delegate property, which can only be done within an instance method.

Read this to get a better grasp of the aforementioned concept.

just change delegate method to class method. like this:

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex;

// - change to +

+ (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex;
