手表按钮按下崩溃 [英] watch button press crash

问题描述

它似乎与

转到 WatchKit 扩展 > InterfaceController.swift 并添加一个新成员

@IBOutlet var scheduleMeetingButton: WKInterfaceButton！

和方法

@IBAction func scheduleMeeting(_ sender: Any) { }

然后返回Interface.storyboard并将这两个链接到按钮

启动应用程序(在手表模拟器上)

然后点击按钮，你会得到这个执行错误

是什么导致了这个错误?

解决方案

从查看您的代码来看，我建议将 action 函数从 sender: any 更新为 sender: wkinterfacebutton 希望这会有所帮助！

it seems to be the same error and conditions as this unanswered SO question, but I have more to add (its really easy to replicate)

Create a new project in the latest Xcode

iOS App with WatchKit App

Go to the WatchKit App > Interface.storyboard and put a single button on the Interface Controller Scene > Interface Controller

Go to WatchKit Extension > InterfaceController.swift and add a new member

@IBOutlet var scheduleMeetingButton: WKInterfaceButton!

and method

@IBAction func scheduleMeeting(_ sender: Any) { }

then go back to Interface.storyboard and link both of these to the button

launch the app (on the watch simulator)

than click the button and you will get this exec error

What is causing this error?

解决方案

From looking at your code i would suggest updating the action function from sender: any to sender: wkinterfacebutton hope this helps!
