Is it possible to NOT dismiss a UIAlertView

Question

The UIAlertviewDelegate protocol has several optional methods including:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonInd

WARNING

From some sources I have heard that few app have got rejected following this process. I was lucky in my case during iOS6 so I am showing code here. Use on your own risk :-/

Subclassing is the best way. Create a bool flag for alert should stay or not.

This is the Subclass of UIAlertView

//
//  UICustomAlertView.h
//

#import 

@interface UICustomAlertView : UIAlertView
{
    
}
@property(nonatomic, assign) BOOL dontDisppear;
@end

//
//  UICustomAlertView.m
//

#import "UICustomAlertView.h"

@implementation UICustomAlertView

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
    }
    return self;
}

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

    if(self.dontDisppear)
        return;
    [super dismissWithClickedButtonIndex:buttonIndex animated:animated];
}
@end

And this is how I used it into my code

if(![txtUsername.text isEqualToString:@"admin"] && ![txtPassword.text isEqualToString:@"admin"])
{
     alertLogin.dontDisppear = YES;
     alertLogin.message = NSLocalizedString(@"my_alert", nil);
}
else
{
     alertLogin.dontDisppear = NO;
     // proceed
}
