actionSheet clickedButtonAtIndex在目標c中不起作用嗎？

我嘗試單擊按鈕，從操作表中選擇，然後將選定的索引設置爲按鈕文本標籤的文本。我的按鈕在下面。但它不會在按鈕文本中顯示選定的索引。我該如何解決這個問題？actionSheet clickedButtonAtIndex在目標c中不起作用嗎？

- (IBAction)cinsiyetBtnClick:(id)sender { 
    popupQuery1 = [[UIActionSheet alloc] initWithTitle:@"Cinsiyetiniz" 
               delegate:self 
            cancelButtonTitle:NO 
           destructiveButtonTitle:NO 
            otherButtonTitles:@"Bay", @"Bayan",nil]; 
    popupQuery1.tag = 1; 
    // popupQuery1.actionSheetStyle = UIActionSheetStyleDefault; 
    [popupQuery1 showInView:[UIApplication sharedApplication].keyWindow]; 
    [popupQuery1 release]; 
} 

- (IBAction)medeniDurumBtnClick:(id)sender { 
    popupQuery1 = [[UIActionSheet alloc] initWithTitle:@"Medeni Durumunuz" 
               delegate:self 
            cancelButtonTitle:NO 
           destructiveButtonTitle:NO 
            otherButtonTitles:@"Evli", @"Bekar",@"Dul",@"Boşanmış",nil]; 
    popupQuery1.tag = 2; 
    // popupQuery1.actionSheetStyle = UIActionSheetStyleDefault; 
    [popupQuery1 showInView:[UIApplication sharedApplication].keyWindow]; 
    [popupQuery1 release]; 
} 

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { 
    if(actionSheet.tag==1){ 
     if (buttonIndex == 0) { 
      self.cinsiyetBtn.titleLabel.text = @"Bay"; 
     } else if (buttonIndex == 1) { 
      self.cinsiyetBtn.titleLabel.text = @"Bayan"; 
     } 
    } 
    else if (actionSheet.tag == 2){ 
     if (buttonIndex == 0) { 
      self.medeniDurumBtn.titleLabel.text = @"Evli"; 
     } else if (buttonIndex == 1) { 
      self.medeniDurumBtn.titleLabel.text = @"Bekar"; 
     } else if (buttonIndex == 2) { 
      self.medeniDurumBtn.titleLabel.text = @"Dul"; 
     } else if (buttonIndex == 3) { 
      self.medeniDurumBtn.titleLabel.text = @"Boşanmış"; 
     } 
    } 
}

你設置UIApplicationDelegate在.h文件中：

所以，現在你應該像這樣的東西替換所有self.cinsiyetBtn.titleLabel.text = @"Bay";？ –

那麼究竟是什麼問題....沒有按鈕標題正在更新？ – Shubhank

有幾種狀態中，按鈕可以是：UIControlStateNormal，UIControlStateHighlighted，UIControlStateSelected和UIControlStateDisabled。

在大多數情況下，當你想更新按鈕的標題應爲正常狀態設置新標題：

[button setTitle:@"New Title" forState:UIControlStateNormal];

有時候你需要設置標題爲所有狀態。

[self.cinsiyetBtn setTitle:@"Bay" forState:UIControlStateNormal];
