我知道这不是这个问题的确切答案，但我在网上寻找答案后找到了这个帖子。我想其他人也有同样的感觉。

这是我的UITapGestureRecognizer的方差，我发现可靠和易于使用-只需设置TextView的委托到ViewController。

而不是ViewDidLoad我添加了UITapGestureRecognizer当TextView成为编辑活动:

-(void)textViewDidBeginEditing:(UITextView *)textView{
    _tapRec = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tap:)];

    [self.view addGestureRecognizer: _tapRec];
    NSLog(@"TextView Did begin");
}

当我在TextView之外点击，视图结束编辑模式和UITapGestureRecognizer删除自己，所以我可以继续与视图中的其他控件进行交互。

-(void)tap:(UITapGestureRecognizer *)tapRec{
    [[self view] endEditing: YES];
    [self.view removeGestureRecognizer:tapRec];
    NSLog(@"Tap recognized, tapRec getting removed");
}

我希望这能有所帮助。这似乎是显而易见的，但我从来没有在网上看到过这个解决方案-我做错了什么吗?

使用导航控制器托管一个栏来解除键盘:

在.h文件中:

UIBarButtonItem* dismissKeyboardButton;

在.m文件中:

- (void)viewDidLoad {
    dismissKeyboardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissKeyboard)];
}

-(void)textViewDidBeginEditing:(UITextView *)textView {
    self.navigationItem.rightBarButtonItem = dismissKeyboardButton;
}

-(void)textFieldDidBeginEditing:(UITextField *)textField {
    self.navigationItem.rightBarButtonItem = dismissKeyboardButton;
}

-(void)dismissKeyboard {
    [self.textField resignFirstResponder];
    [self.textView resignFirstResponder];
    //or replace this with your regular right button
    self.navigationItem.rightBarButtonItem = nil;
}

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
    if([text isEqualToString:@"\n"])
        [textView resignFirstResponder];
    return YES;
}

yourtextView.delegate=self;

还要添加UITextViewDelegate

别忘了确认协议

如果你没有添加IF ([text isEqualToString:@"\n"])，你就不能编辑

迅速回答:

override func viewDidLoad() {
    super.viewDidLoad()
    let tapGestureReconizer = UITapGestureRecognizer(target: self, action: "tap:")
    view.addGestureRecognizer(tapGestureReconizer)
}

func tap(sender: UITapGestureRecognizer) {
    view.endEditing(true)
}

斯威夫特

func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {
    if text == "\n" {
        textView.resignFirstResponder()
    }
    return true
}

我知道这已经回答了，但我真的不喜欢使用字符串字面量的换行，所以这是我所做的。

- (BOOL)textView:(UITextView *)txtView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
    if( [text rangeOfCharacterFromSet:[NSCharacterSet newlineCharacterSet]].location == NSNotFound ) {
        return YES;
    }

    [txtView resignFirstResponder];
    return NO;
}

Swift 4.0更新:

func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
if (text as NSString).rangeOfCharacter(from: CharacterSet.newlines).location == NSNotFound {
    return true
}
txtView.resignFirstResponder()
return false
}
