我想知道如何使键盘消失时,用户触摸以外的UITextField。

你需要添加一个UITapGestureRecogniser并将其分配给视图,然后在它的选择器上的UITextField上调用resign first responder。
代码:
在viewDidLoad
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];
[self.view addGestureRecognizer:tap];
在dismissKeyboard:
-(void)dismissKeyboard
{
[aTextField resignFirstResponder];
}
(其中,aTextField是负责键盘的文本字段)
Swift 3版本是这样的
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.dismissKeyboard (_:)))
self.view.addGestureRecognizer(tapGesture)
对于dismissKeyboard
@objc func dismissKeyboard (_ sender: UITapGestureRecognizer) {
aTextField.resignFirstResponder()
}
其他回答
设置文本字段委托视图didload: 重载函数viewDidLoad() { super.viewDidLoad () self. usertext .delegate = self } 添加此函数: func textFieldShouldReturn(userText: UITextField! { userText.resignFirstResponder () 返回true; }
最好是让你的UIView成为UIControl的一个实例(在界面构建器中),然后连接他们的TouchUpInside事件来解散键盘方法。这个IBAction方法看起来像:
- (IBAction)dismissKeyboard:(id)sender {
[aTextBox resignFirstResponder];
}
在viewDidLoad 斯威夫特4.2 代码是这样的
let viewTap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action:#selector(dismissKeyboard))
view.addGestureRecognizer(viewTap)
@objc func dismissKeyboard() {
view.endEditing(true)
}
在我的新发展中,我以巴里为例。它工作得很好!但我不得不包括一个轻微的变化,要求解散键盘,只有文本字段被编辑。
所以,我在Barry的例子中加入了以下内容:
- (void) textFieldDidBeginEditing:(UITextField *)textField
{
_textBeingEdited = textField;
}
-(void) textFieldDidEndEditing:(UITextField *)textField
{
_textBeingEdited = nil;
}
同时,我修改了hideKeyboard方法如下:
- (IBAction)hideKeyboard:(id)sender
{
// Just call resignFirstResponder on all UITextFields and UITextViews in this VC
// Why? Because it works and checking which one was last active gets messy.
//UITextField * tf = (UITextField *) sender;
[_textBeingEdited resignFirstResponder];
}
藏品视图:
// the keyboard follows the dragging touch off screen, and may be pulled upward again to cancel the dismiss
collectionView.keyboardDismissMode = .interactive
// dismisses the keyboard when a drag begins
collectionView.keyboardDismissMode = .onDrag
