问题描述
我在UIView中添加了Label,并创建了它的出口,然后在UITapGestureRecognizer的帮助下,我添加了功能,但是当我点击或单击Label时.标签文本不会更改.我搜索了类似的问题,得到的答案也就是我所写的内容,但标签文本仍未更改.用Swift 3.0编写的代码. 这是我编写的代码-
I have added Label in the UIView and created its outlet, then with the help of UITapGestureRecognizer i have added the functionality,but when i tap or click in the label. Label text does not changes. I searched for the similar question and i got the answer also its what I've written but still the label text is not changing. Code written in Swift 3.0. Here's the code i have written -
import UIKit
class testingViewController: UIViewController {
@IBOutlet weak var testLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let tap:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(showDatePicker))
tap.numberOfTouchesRequired = 1
tap.numberOfTapsRequired = 1
testLabel.addGestureRecognizer(tap)
testLabel.isUserInteractionEnabled = true// after adding this it worked
// Do any additional setup after loading the view.
}
func showDatePicker(){
print("testing")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
推荐答案
是的,但是您需要将标签的isUserInteractionEnabled
标志设置为true
Yes you can, but you need to set the label's isUserInteractionEnabled
flag to true
