UIAlertView点击按钮不会销毁自身View

子类化UIAlertView,复写方法
- (void)dismissWithClickedButtonIndex:(NSInteger)buttonIndex animated:(BOOL)animated;

/// UIAlertView subclass which can't be dismissed when buttons clicked.
@interface FixAlertView : UIAlertView

@end

@implementation FixAlertView

- (void)dismissWithClickedButtonIndex:(NSInteger)buttonIndex animated:(BOOL)animated {

//    [super dismissWithClickedButtonIndex:buttonIndex animated:animated];
return;
}

@end

复写方法的时候，记得不要调用父类的方法。
