How to handle multiple UIAlertControllers in iOS?

I have to show multiple UIAlerts in one viewController before iOS8 we can use the UIAlerts with tags and we can identify in clickedButtonAtIndex using tags like.

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(alertView.tag == 1)
{
//UIAlert1 button clicked
}

if(alertView.tag == 2)
{
//UIAlert2 button clicked
}
}

so we can do stuff. how to identify button clicks of different UIAlertControllers. Because one alert1 button click i have to change the some text color and alert2 button click i have to pop the view controller.

UIAlertController is block-based.

Create an UIAlertAction instance for each action and pass the block to be executed after the button is tapped.

For further information read the UIAlertController "review" of Mattt Thompson.

You can do the following way.

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
 {
  if(alertView.tag == 1)
    {
      //UIAlert1 button clicked
         if(buttonIndex==0){//say, **Cancel** button tag
            //alert2 "Cancel" button has tapped
          }else if(buttonIndex==1){say, **OK** button tag
            //alert2 "OK" button has tapped
           }
    }

  if(alertView.tag == 2)
    {
      //UIAlert2 button clicked
      if(buttonIndex==0){//say, **Yes** button tag
           //alert2 "YES" button has tapped
          }
    }
}
