UIAlertView中不會記錄結果

Question

我想記錄，如果用戶對我的alertView按下OK，但它什麼都不做......這是我的檢查：

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { 
    if (buttonIndex == 0) { NSLog(@"user pressed OK"); } 
} 

而且它在我的@interface：

@interface FirstViewController : UIViewController<UIWebViewDelegate, UIAlertViewDelegate> 

這是我的alertView：

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oeps..." 
              message:@"This is just a random message." 
              delegate:nil 
              cancelButtonTitle:@"OK" 
              otherButtonTitles:nil]; 
[alertView show]; 

有誰看到PROBL他們嗎？我試圖做一個NSLog外if buttonIndex，但不會太登錄..

感謝

而是委託是零的，轉讓將委託作爲自我

Answer 2

使用以下命令：

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oeps..." 
             message:@"This is just a random message." 
             delegate:self 
             cancelButtonTitle:@"OK" 
             otherButtonTitles:nil]; 
[alertView show]; 

Answer 3

檢查你的委託你通過委託給nil。它傳遞給自這就是whay這種情況正在發生......

這樣

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oeps..." 
              message:@"This is just a random message." 
              delegate:self 
              cancelButtonTitle:@"OK" 
              otherButtonTitles:nil]; 
[alertView show];
