ios - 当 iOS 应用程序在前台时处理小部件单击操作

Question

单击小部件时，如果应用程序未运行，我可以使用以下方法进行处理-

(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url 

但是如果app在后台怎么处理呢？

Answer 1

handleOpenURL无论 App 是否处于后台模式都会被调用。

Official document:
If a URL arrives while your app is suspended or running in the background, the system moves your app to the foreground prior to calling this method.

以及影响调用的因素:

This method is not called if the delegate returns NO from both the application:willFinishLaunchingWithOptions: and application:didFinishLaunchingWithOptions: methods. (If only one of the two methods is implemented, its return value determines whether this method is called.) If your app implements the applicationDidFinishLaunching: method instead of application:didFinishLaunchingWithOptions:, this method is called to open the specified URL after the app has been initialized.

从iOS9.0开始最好使用以下方法:

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options NS_AVAILABLE_IOS(9_0);
