恐怕你錯了，因爲他們都在談論當鍵盤不是數字類型，我知道如何禁用鍵盤，當它不是數字，不同的情況下，當你不得不消失「數字鍵盤」。在提出這個問題之前我搜索一下。 – itsaboutcode 2009-09-10 22:58:35

一旦用戶輸入號碼，您可以輕鬆地在屏幕上放置一個按鈕以關閉鍵盤。這不是電話應用程序的工作原理嗎？或者你可以在鍵盤上方放一個工具欄，上面有一個「don」按鈕，或者任意數量的東西（在x秒不活動後自動關閉鍵盤，一旦字段中的文本確認等等） – 2009-09-10 23:11:57

迴應試試這個：

[theTextField resignFirstResponder];

那麼你在我上面寫過的函數中這樣做，就像這樣。無論如何，我應該把這個代碼工作？ – itsaboutcode 2009-09-10 22:53:33

我在我的視圖中有很多文本框，它也不適用於數字鍵盤 – 2012-06-19 13:24:57

下面是答案..

-(void) touchesBegan :(NSSet *) touches withEvent:(UIEvent *)event 

{ 

    //[URL resignFirstResponder]; 

    //[Password resignFirstResponder]; 

    [speedField resignFirstResponder]; 

    [super touchesBegan:touches withEvent:event ]; 

}

-1這是一個完全的黑客，不應該使用。如果蘋果決定將「UIKeyboard」的名稱更改爲「UIKBView」，該怎麼辦？您絕不應該依賴未記錄的行爲或實現細節來使代碼正常工作。如果你需要沒有無證材料的行爲，請提交一個錯誤。 – 2010-12-05 21:30:02

爲什麼不使用「Numbers and Punctuation」鍵而不是「Numeric」？這將節省您的時間

使用resignFirstResponder中的touchesBegan，像這樣：

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { 
    UITouch * touch = [touches anyObject]; 
    if(touch.phase == UITouchPhaseBegan) { 
     [self.myTextField resignFirstResponder]; 
    } 
}

您可能需要，如果你不知道在哪裏焦點當前位於調用此對多個文本字段;我沒有測試過這種情況。

此外，在界面生成器，你將需要啓用該視圖的「已啓用用戶交互」複選框，或編程使用：

myView.userInteractionEnabled = YES;
