如何在UIScrollView中爲鍵盤實現ResignFirst Responder？

Question

可能重複：
Dismiss keyboard on touch anywhere outside UITextField

我在我的應用程序中使用的UIScrollView。我正在放幾個文本字段和按鈕。當他們觸摸文本框之外時我想隱藏我的鍵盤。 （我的意思是他們將錄製uiscrollview）。我已經嘗試了很多東西......我用UIGestureRecognizer但它不工作...幫助請

Answer 1

這裏只是試圖解決方案，它希望有幫助

將下面的代碼添加到您的viewDidLoad;

-(void)viewDidLoad { 
    //create a tapGesture which calls a removeKeyboard method 
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(removeKeyboard)]; 

    tapGesture.cancelsTouchesInView = NO; 

    [self.yourScrollView addGestureRecognizer:tapGesture]; 
} 

-(void)removeKeyboard { 
    [self.yourTextField resignFirstResponder]; 
} 

希望幫助....

試着在你看來下面的代碼...

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { 
    UITouch *touch = [[event allTouches] anyObject]; 
    if ([yourTextView isFirstResponder] && [touch view] != yourTextView) { 
     [yourTextView resignFirstResponder]; 
    } 
}
