將IBAction添加到UIAlert

Question

我試圖讓我的UIAlert在單擊按鈕時執行兩個不同的操作。當用戶點擊重新啓動時，遊戲重新開始，當主菜單被點擊時，遊戲應該進入主菜單。重置按鈕工作正常，但IBAction不斷給我提供有關切換視圖的錯誤。

// called when the player touches the "Reset Game" button 
- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { 
    // the user clicked one of the OK/Cancel buttons 
    if (buttonIndex == 0) 
    { 
     [self resetGame]; 
    } 
    else 
    { 
     - (IBAction)showFlip:(id)sender { 
      Menu *menuView = [[[menu alloc] init] autorelease]; 
      [gameView setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal]; 
      [self presentModalViewController:menuView animated:YES]; 

     } 

    } 



    } 

重置工作正常，但我得到IBAction兩個錯誤。 'showFlip'未聲明（首次在此函數中使用）和期望';'之前'：'令牌。不明白爲什麼會這樣說，因爲當我在alertview之外發布IBAction時，它工作正常。 任何幫助，將不勝感激，在此先感謝

Answer 1

您正在定義一個方法，而不是調用一個！此代碼

- (IBAction)showFlip:(id)sender { 
      Menu *menuView = [[[menu alloc] init] autorelease]; 
      [gameView setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal]; 
      [self presentModalViewController:menuView animated:YES]; 

     } 

不應該住在這個函數裏面。拔不出來是

- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { 
    // the user clicked one of the OK/Cancel buttons 
    if (buttonIndex == 0) 
    { 
     [self resetGame]; 
    } 
    else 
    { 
     [self showFlip]; 
    } 
} 

-(void)showFlip{ 
    Menu *menuView = [[[menu alloc] init] autorelease]; 
    [gameView setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal]; 
    [self presentModalViewController:menuView animated:YES]; 
}

你應該試試這個：

// called when the player touches the "Reset Game" button 
- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { 
    // the user clicked one of the OK/Cancel buttons 
    if (buttonIndex == 0) 
    { 
     [self resetGame]; 
    } 
    else 
    { 
     [self showFlip:nil]; 
    } 
} 

- (IBAction)showFlip:(id)sender { 
    Menu *menuView = [[[menu alloc] init] autorelease]; 
    [gameView setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal]; 
    [self presentModalViewController:menuView animated:YES]; 
}
