我正在創建一個簡單的模態ViewController。我用一個按鈕創建一個筆尖,然後按下該按鈕,調用一個方法來顯示模式viewController,我在其中創建viewController和一個按鈕,像這樣。Modal viewController解僱按鈕問題

UIViewController *modalViewController = [[UIViewController alloc]initWithNibName:nil bundle:nil]; 
modalViewController.view.backgroundColor = [UIColor redColor]; 
modalViewController.; 

UIButton *btnDismissViewController = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
btnDismissViewController.frame = CGRectMake(60, 160, 150, 50); 
[btnDismissViewController setTitle:@"DISMISS" forState:UIControlStateNormal]; 
[btnDismissViewController addTarget:self action:@selector(dismissViewCOntroller) forControlEvents:UIControlEventTouchUpOutside]; 

btnDismissViewController.backgroundColor = [UIColor grayColor]; 
[modalViewController.view addSubview:btnDismissViewController]; 

[self presentModalViewController:modalViewController animated:YES]; 

該視圖正常顯示,但在按下modalViewController上的按鈕後,不會調用解除modalViewController的目標方法。我肯定錯過了明顯的東西,但沒有得到什麼。任何人都可以幫忙嗎?

Thanx提前。

請向我們展示'dismissViewCOntroller'方法的定義。您定義選擇器的方式應該如下所示,使用兩個大寫字母和全部:' - (void)dismissViewCOntroller'(無發送者參數)。 – 2010-06-26 20:05:05

另外,你確定你不是故意寫'UIControlEventTouchUpInside'嗎? – 2010-06-26 20:05:48

感謝名單,奧,IWasRobbed和Macatomy ......是的,有一個錯字。我應該寫「UIControlEventTouchUpInside」,這無意中被寫成UIControlEventTouchUpOutside .. – neha 2010-06-28 06:12:34

我同意奧萊的評論...此外,請確保您在您與此類似dismissViewCOntroller方法內貶:

[self.parentViewController dismissModalViewControllerAnimated:YES];

我覺得可能是在你的代碼一個錯字,dismissViewCOntroller好像它應該是dismissViewController,但也許這是故意的,並且控制狀態應該是UIControlEventTouchUpInside
