Question

我有一个UIDatePicker，我想像在关闭键盘一样在按钮外轻按时将其隐藏，我已经尝试了所有操作，但似乎无济于事。

import UIKit

ViewController类：UIViewController {

@IBOutlet weak var datePicker: UIDatePicker!
@IBOutlet weak var BDbtn: UIButton!


override func viewDidLoad() {
    super.viewDidLoad()

    datePicker.isHidden = true
    datePicker?.datePickerMode = .date
    let formatter = DateFormatter()
    formatter.dateFormat = "dd/MM/yyyy"
    BDbtn.setTitle("Pick a date!", for: .normal)
}
@IBAction func dateChanged(_ sender: Any) {
    let formatter = DateFormatter()
    formatter.dateFormat = "dd/MM/yyyy"
    BDbtn.setTitle(formatter.string(from: datePicker.date), for: .normal)

}
@IBAction func BDpressed(_ sender: Any) {
    if datePicker.isHidden {
        datePicker.isHidden = false
    } else {
        datePicker.isHidden = true
    }
}

}

Answer 1

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

Answer 2

如果您在Scrollview或主UIView中添加了datePicker。您可以使用UITapGestureRecogniser并在手势方法中添加一行代码：

self.view.endEditing（true）

就是这样。
