Question

Crash when open containing app from today extension可能重复。

我尝试使用自定义网址方案从今天的扩展程序小部件中打开包含应用程序。我在扩展程序中使用的代码是：

let urlStr = String(format: "myapp://?device_id=%@", deviceId!)
let url = NSURL(string: urlStr)
self.extensionContext!.openURL(url!, completionHandler: nil)

但是，打开时包含应用程序会崩溃：

从其他任何地方打开时，相同的自定义URL方案正在运行。

使用Xcode 6.1.1，部署目标8.1。

管理自己解决这个问题，并认为我会发布解决方案。

事实证明，Xcode的早期版本之一自动完成的UIApplicationDelegate声明不正确：

func application(application: UIApplication, 
                 openURL url: NSURL, 
                 sourceApplication: String!,   // Wrong
                 annotation: AnyObject?) -> Bool

应该是：

func application(application: UIApplication, 
                 openURL url: NSURL, 
                 sourceApplication: String?,   // OK
                 annotation: AnyObject?) -> Bool

（sourceApplication需要String?而不是String!）

希望这有助于某人。
