UIAlertView in xCode

Here i am showing you an Alert as in below Image

It has 2 buttons OK and Cancel. We can put any name in place of "OK" or "Cancel".

Ok... So here is the simple code for this.

1. First define a UIAlertView in top like

@property (nonatomic) UIAlertView *alert;

2. Add Alert like below 

self.alert = [[UIAlertView alloc]initWithTitle:@"Signup Alert"

              

                                       message:@"We will redirect to our site. where you can signup through your details. Press Ok to switch there or Canel to skip signup."

                                      delegate:nil

                             cancelButtonTitle:@"OK"

                             otherButtonTitles:@"Cancel", nil];

self.alert.delegate = self;

self.alert.tag=101;//add tag to alert

[self.alert show];

3. Now if you have declared delegate to self then write the below function, which will be called automatically.

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

{

    if(self.alert.tag ==101)     // check alert by tag

    {

        if (buttonIndex == 0)

        {

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://myURL.com/signupPage.aspx"]];

        }

        else

        {

            //Skipping Signup

        }

    }

}
