Ios 在UiAlertView中按下按钮时如何运行选择器

因此，我有以下代码，当回合结束时，它会弹出以下

UIAlertView

。现在，当用户按下排行榜按钮时，我希望它运行显示排行榜的

-（void）

语句。请不要以为这都是在一个精灵套件视图控制器。我该怎么做

另外，我在另一个类中有我的void语句，是否通过

#import

将其带过来

 - (void) gameEnded
    {
        // indicate our game state as stopped
        _gameState = STOPPED;

        // create a message to let the user know their score
        NSString *message = [NSString stringWithFormat:@"You scored %d this time", _score];

        // show the message to the user
        UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Game over!"
                                                     message:message
                                                    delegate:nil
                                           cancelButtonTitle:@"Ok"
                                           otherButtonTitles:@"Leaderboards",nil];
        [av show];
        // reset the score tracker for the next game
        _score = 0;

        //reset playing area
        [self removeAllBlocks];
        [self addBlocks];



    }

在这里：

您需要将委托设置为“self”，或者将要作为其委托处理警报视图事件的另一个类。该类必须符合

UIAlertViewDelegate

，例如：

@interface YourController : YourControllerSuperClass <UIAlertViewDelegate> 

 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
   // In case there are more then one alert view and a reference to each of the alert views are kept.
   if(alertView == self.avAlertView){
      switch(buttonIndex){
         // Your button's cases!
      }

   }
}

因为这是当按下按钮时，代理上的警报视图调用的方法。 在这里，您将收到对警报视图的引用和按下按钮的索引。 通过此操作，您可以找到执行了哪些操作。 例如：

@interface YourController : YourControllerSuperClass <UIAlertViewDelegate> 

 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
   // In case there are more then one alert view and a reference to each of the alert views are kept.
   if(alertView == self.avAlertView){
      switch(buttonIndex){
         // Your button's cases!
      }

   }
}

您当前的

控制器

应实现

UIAlertViewDelegate

，并使用您的

排行榜

按钮的索引调用方法

alertView:ClickedButtonIndex:

您的

CustomController.h

：

#import <UIKit/UIKit.h>

@interface AdsEventViewController : UITabBarController<UIAlertViewDelegate>

@end

代表是坏的，区块是好的！下面是使用警报视图的更好方法。
