如何知道应用用户是否点击推送通知ios？

Question

我想检测用户是否点击推送通知来启动应用程序或将其置于前台。

Answer 1

在你的AppDelegate只需实现方法

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo; 

Answer 2

如果没有运行didFinishLaunchingWithOptions方法的应用程序被调用的应用程序启动时，你可以检查launchOptions参数是这样的：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 

    if (launchOptions != nil) { 
     NSDictionary *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 
     if (notification) { 
      // Launched from push notification 
     } 

    } 
} 

如果应用程序已启动，则可以使用此方法：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 
{ 
    if (application.applicationState == UIApplicationStateInactive || application.applicationState == UIApplicationStateBackground ) 
    { 
     //opened from a push notification when the app was on background 
    } 
} 

你也可以检查： Detect if the app was launched/opened from a push notification
