創建alertview和獲取標籤竊聽

Question

我試圖創建一個自定義alertview類，但我創建視圖完成塊有問題抽頭

我想是這樣的，

+ (void)alertview:(UIViewController*)vc handler:(void (^)(UITapGestureRecognizer *))callback{ 
    UILabel *lbl1 = [[UILabel alloc] init]; 
    lbl1.text = @"A"; 
    UILabel *lbl2 = [[UILabel alloc] init]; 
    lbl1.text = @"B"; 
    UILabel *lbl3 = [[UILabel alloc] init]; 
    lbl1.text = @"C"; 
} 

當用戶觸摸，例如，LBL2

[RFAlertView alertview:self handler:^(UITapGestureRecognizer *selected){ 
        NSLog(@"selected label is : %@",selected); 
       }];
