推荐答案
如果你的后台程序/前台模式调用此方法
if your app in background/foreground mode call this method
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler如果你使用上面的方法,你将面临控制台下面的错误
if you used the above method you will face the following error in console
应用:didReceiveRemoteNotification:fetchCompletionHandler:],但你仍然需要远程通知添加到您的支持UIBackgroundModes名单在你的Info.plist
application:didReceiveRemoteNotification:fetchCompletionHandler:], but you still need to add "remote-notification" to the list of your supported UIBackgroundModes in your Info.plist.
的要解决此问题
请按照步骤的图片
如果您在前台模式的应用程序调用此方法
if your app in foreground mode call this method
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo选择NO-2
- (void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { UIApplicationState state = [application applicationState]; // user tapped notification while app was in background if (state == UIApplicationStateInactive || state == UIApplicationStateBackground) { // go to screen relevant to Notification content } else { // App is in UIApplicationStateActive (running in foreground) // perhaps show an UIAlertView } }斯威夫特
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) { var state: UIApplicationState = application.applicationState() // user tapped notification while app was in background if state == .Inactive || state == .Background { // go to screen relevant to Notification content } else { // App is in UIApplicationStateActive (running in foreground) // perhaps show an UIAlertView } }更多推荐
在后台模式didReceiveRemoteNotification不叫
