iphone - 在 iPhone 的后台启动应用程序

Question

有没有一种方法可以使用 url 方案方法在后台启动应用程序，或者如果它已经在后台运行，则调用它而不需要它(被调用者)来到前台？我听说这可以在 iOS 4.2 中完成，但当我使用时没有看到它

[[UIApplication 共享应用程序] openURL:url];

打开应用程序。谢谢，N.

看起来不可能。

If your application is not running when a URL request arrives, it is launched and moved to the foreground so that it can open the URL. The implementation of your application:didFinishLaunchingWithOptions: method should retrieve the URL from its options dictionary and determine whether the application can open it. If it can, return YES and let your application:openURL:sourceApplication:annotation: or application:handleOpenURL: method handle the actual opening of the URL.

If your application is running but is in the background or suspended, it is moved to the foreground to open the URL. Shortly thereafter, the system calls the delegate’s application:openURL:sourceApplication:annotation: to check the URL and open it. If your delegate does not implement this method (or the current system version is iOS 4.1 or earlier), the system calls your delegate’s application:handleOpenURL: method instead.
