我想知道如何使键盘消失时,用户触摸以外的UITextField。

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

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];
}

用这个扩展方法设置你的UIViewController,例如在viewDidLoad中:

override func viewDidLoad() {
    super.viewDidLoad()
    self.setupHideKeyboardOnTap()
}

即使点击导航栏,键盘也会被取消。

import UIKit
extension UIViewController {
    /// Call this once to dismiss open keyboards by tapping anywhere in the view controller
    func setupHideKeyboardOnTap() {
        self.view.addGestureRecognizer(self.endEditingRecognizer())
        self.navigationController?.navigationBar.addGestureRecognizer(self.endEditingRecognizer())
    }

    /// Dismisses the keyboard from self.view
    private func endEditingRecognizer() -> UIGestureRecognizer {
        let tap = UITapGestureRecognizer(target: self.view, action: #selector(self.view.endEditing(_:)))
        tap.cancelsTouchesInView = false
        return tap
    }
}

看看这个,这是最简单的方法,

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
      [self.view endEditing:YES];// this will do the trick
}

Or

这个库将处理包括滚动条自动滚动,点击空间隐藏键盘等…

objective - c:

在ViewController中添加这段代码。M文件:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.view endEditing:YES];
}

迅速:

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    view.endEditing(true)
}

只是使用这段代码在您的.m文件,它将辞职的文本字段,当用户点击文本字段之外。

 -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
  [textfield resignFirstResponder];
 }
