在 iOS 8.x 下尝试注册推送通知时:

application.registerForRemoteNotificationTypes(UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound)

我收到以下错误:

registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later.

任何想法什么是做它的新方法？当我在 iOS 7.x 上运行这个 Swift 应用程序时，它确实有效。

编辑

在 iOS 7.x 上，当我包含我得到的条件代码时(SystemVersion 条件或 #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000)

dyld: Symbol not found: _OBJC_CLASS_$_UIUserNotificationSettings

最佳答案

对于 iOS

- (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;
}

适用于 iOS10
