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
}
}
