Swift：UITextField在第一次点击时被立即解雇

Question

当我打开应用程序并单击UITextField时，它在第一次点击时立即被解散。它不会在第一次之后被点击，而不会在视图之外点击。

我用这个回答：Close iOS Keyboard by touching anywhere using Swift为代码来关闭textField区域以外的区域时被点击。代码：

class SettingsViewController: UIViewController, UITextFieldDelegate { 

@IBOutlet weak var textField: UITextField! 

override func viewDidLoad() { 
    super.viewDidLoad() 

    textField.delegate = self 
} 


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


func textFieldShouldReturn(_ textField: UITextField) -> Bool { 

    textField.resignFirstResponder() 
    return false 
}

我想从你的问题，你想什么时候有人视图，而不是文本字段水龙头关闭该键盘。您可以覆盖触摸开始您的视图控制器为此于：

import UIKit 

class ViewController: UIViewController { 

    // MARK: - Properties 
    @IBOutlet weak var textField: UITextField! 

    // MARK: - Actions 
    // will resign any first repsonder on this view contorller 
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { 
     view.endEditing(true) 
    } 

    // MARK: - Lifecycle 
    override func viewDidLoad() { 
     textField.delegate = self 
    } 

} 

extension ViewController: UITextFieldDelegate { 
    func textFieldShouldReturn(_ textField: UITextField) -> Bool { 
     textField.resignFirstResponder() 
     return false 
    } 
} 

，而不必担心水龙头等
