iOS iOS8中 問題"registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later" 解決方案

問題重述：

iOS 8中改變了通知註冊的方式，如果App需要同時支援iOS 7 和 8 的話，需要首先檢查selector。

解決方案：在Xcode 6中

 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions{    //-- Set Notification    if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])     {           // iOS 8 Notifications           [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];           [application registerForRemoteNotifications];    }    else    {          // iOS < 8 Notifications          [application registerForRemoteNotificationTypes:                     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];    }     //--- your custom code     return YES;}
