ios notification

Apple's notifications are divided into local notifications and remote notifications

• If the user starts directly, there is no data in launchOptions;
• If it is launched by other applications through openURL:, the object corresponding to UIApplicationLaunchOptionsURLKey is the launch URL (NSURL), and UIApplicationLaunchOptionsSourceApplicationKey corresponds to the bundle ID (NSString) of the source application launched;
• If it is started by local notification, UIApplicationLaunchOptionsLocalNotificationKey corresponds to the local notification object ( UILocalNotification ) for starting the application ;
• If it is started by remote notification, UIApplicationLaunchOptionsRemoteNotificationKey corresponds to the remote notification information userInfo (NSDictionary) of the starting application;
• Other keys are UIApplicationLaunchOptionsAnnotationKey, UIApplicationLaunchOptionsLocationKey,
  UIApplicationLaunchOptionsNewsstandDownloadsKey.

No sound for local notifications when app is in foreground
