iOS 8 Beta Today扩展小部件未在Swift应用中显示？ [英] iOS 8 Beta Today extension widget not showing in a Swift app?

问题描述

今天的扩展程序没有出现在Swift应用程序中，但它在Objective C应用程序中出现。

我所做的是在故事板上为快速和客观的c应用添加一些UILabel和一些内容。

<当我运行Objective C应用程序时，它出现了，但是当我执行Swift应用程序时却没有。

我在这里遗漏了什么吗？

解决方案

你可以注释掉提供的init方法。

  // init（nibName nibNameOrNil：String？，bundle nibBundleOrNil：NSBundle？）{
 // super.init（nibName：nibNameOrNil，bundle：nibBundleOrNil）
 // / /自定义初始化
 //} 
  

这将使您的分机正常运行。这个问题似乎是由Swift和Objective-C之间不同的初始化程序行为引起的。删除上面的初始化程序将从超类继承所有必需的初始化程序。

找到该解决方案供您参考。

注意：您可能必须清理并构建之后，在更改生效之前执行此项目

扩展实际上是崩溃，错误如下：

 致命错误：使用未实现的初始化程序'init（coder :)' for class'com_blabla_blabla_MyTodayExtension.TodayViewController'
  

这表示另一个选项是实现：

  init（coder aDecoder：NSCoder！）{
 super.init（coder：aDecoder）
 //自定义初始化
} 
  

如果你想保留t的能力o进行自定义初始化。

Today extension doesn't show up in a Swift app, but it does in a Objective C app.

What I did was to add a UILabel with some content on the storyboard for the swift and objective c apps.

It showed up when I ran the Objective C app, but not when I executed the Swift app.

Am I missing something here?

解决方案

You can comment out the supplied init method.

//    init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
//        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
//        // Custom initialization
//    }

This will allow your extension to run properly. The issue seems to be caused by differing initializer behavior between Swift and Objective-C. Removing the above initializer will inherit all of the required initializers from the superclass.

Found that solution on the apple developer forums for your reference.

Note: You may have to Clean and Build your project after doing this before the changes will have any effect

The extension is actually crashing, with an error like:

fatal error: use of unimplemented initializer 'init(coder:)' for class 'com_blabla_blabla_MyTodayExtension.TodayViewController'

This indicates that another option would be to implement:

init(coder aDecoder: NSCoder!) {
    super.init(coder: aDecoder)
    // Custom initialization here
}

if you want to retain the ability to do custom initialization.
