只有对于Alertview

#define SHOW_ALERT(title,msg,del,cancel,other) \ 
do { \ 
UIAlertView *_alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:del cancelButtonTitle:cancel otherButtonTitles:other,nil]; \ 
[_alert show]; \ 
} while(0); 

只有对于AlertViewController

#define SHOW_ALERT2(title,msg,ButtonTitle)\ 
do { \ 
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:msg preferredStyle:UIAlertControllerStyleAlert];\ 
    UIAlertAction *actionOk = [UIAlertAction actionWithTitle:ButtonTitle\ 
                 style:UIAlertActionStyleDefault\ 
                handler:nil]; \ 
    [alertController addAction:actionOk];\ 
    [self presentViewController:alertController animated:YES completion:nil];\ 
}while(0); 

两种AlertView和AlertViewController

#define SHOW_ALERT3(title,msg,delegate,ButtonTitle) \ 
    do { \ 
     if ([UIAlertController class]) {\ 
      UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:msg preferredStyle:UIAlertControllerStyleAlert];\ 
      UIAlertAction *actionOk = [UIAlertAction actionWithTitle:ButtonTitle\ 
      style:UIAlertActionStyleDefault\ 
      handler:nil]; \ 
      [alertController addAction:actionOk];\ 
      [self presentViewController:alertController animated:YES completion:nil];\ 
     }\ 
     else {\ 
      UIAlertView *_alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:delegate cancelButtonTitle:ButtonTitle otherButtonTitles:nil]; \ 
      [_alert show]; \ 
     }\ 
    }while(0);
