Crash when open containing app from today extension 的可能重复项.
我正在尝试使用自定义 URL 方案从今天的扩展小部件打开包含应用程序。我在扩展中使用的代码是:
let urlStr = String(format: "myapp://?device_id=%@", deviceId!)
let url = NSURL(string: urlStr)
self.extensionContext!.openURL(url!, completionHandler: nil)
但是，包含应用程序在打开时崩溃:

从其他任何地方打开时，相同的自定义 URL 方案都有效。
使用 Xcode 6.1.1，部署目标 8.1。
设法自己解决了这个问题，并认为我会发布解决方案。
事实证明，由 Xcode 先前版本之一自动完成的 UIApplicationDelegate 声明是不正确的:
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 需要是 String? 而不是 String!)
希望这对某人有所帮助。
