CNContactViewController上的iOS 13.1中的键盘覆盖操作表 [英] Keyboard overlaying action sheet in iOS 13.1 on CNContactViewController

问题描述

这似乎特定于iOS 13.1，因为它可以在iOS 13.0和更早版本上按预期工作，可以在CNContactViewController中添加联系人，如果我取消"，操作表会被键盘重叠.没有执行任何操作，也没有关闭键盘.

This seems to be specific to iOS 13.1, as it works as expected on iOS 13.0 and earlier versions to add a contact in CNContactViewController, if I 'Cancel', the action sheet is overlapping by keyboard. No actions getting performed and keyboard is not dismissing.

推荐答案

我找不到解散键盘的方法.但是至少您可以使用我的方法弹出ViewController.

I couldn't find a way to dismiss keyboard. But at least you can pop ViewController using my method.

1. 不知道为什么，但是无法在CNContactViewController中关闭键盘.我尝试了endEditing :，创建新的UITextField firstResponder，依此类推.什么都没用.
2. 我尝试更改取消"按钮的操作.您可以在NavigationController堆栈中找到此按钮，但是每次输入内容时，它的动作都会更改.
3. 最后，我使用了方法.如前所述，我找不到关闭键盘的方法，但是至少当按下取消"按钮时，您可以关闭CNContactViewController.

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        changeImplementation()
    }

    @IBAction func userPressedButton(_ sender: Any) {
        let controller = CNContactViewController(forNewContact: nil)
        controller.delegate = self
        navigationController?.pushViewController(controller, animated: true)
    }

    @objc func popController() {
        self.navigationController?.popViewController(animated: true)
    }

    func changeImplementation() {
        let originalSelector = Selector("editCancel:")
        let swizzledSelector = #selector(self.popController)

        if let originalMethod = class_getInstanceMethod(object_getClass(CNContactViewController()), originalSelector),
            let swizzledMethod = class_getInstanceMethod(object_getClass(CNContactViewController()), swizzledSelector) {

            method_exchangeImplementations(originalMethod, swizzledMethod)
        }
    }
}
