ios - 推送通知 - UIUserNotificationType 错误

Question

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  ...
  UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                              UIUserNotificationTypeBadge |
                                              UIUserNotificationTypeSound);
  UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                       categories:nil];
  [application registerUserNotificationSettings:settings];
  [application registerForRemoteNotifications];
  ...
}

是否可以让它在带有 iOS 7 的 xcode 5.1 中工作？

    if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")){
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
                                                                                         |UIRemoteNotificationTypeSound
                                                                                         |UIRemoteNotificationTypeAlert) categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}
else
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
