ios - iOS9.3.5如何注册自定义推送通知？

Question

这就是我的应用程序注册推送通知的方式。

@implementation AppDelegate

//REGISTER FOR THE NOTIFICATIONS TYPES
- (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
    _storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

}

 _storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
 [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
 (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert)];


if (launchOptions != nil)
{
    NSDictionary* dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (dictionary != nil)
    {
        NSLog(@"Launched from push notification: %@", dictionary);
        /*[self addMessageFromRemoteNotification:dictionary updateUI:NO];*/
    }
}
return YES;
}

运行应用程序时，我会回显设备 token 以确保是什么。

在运行 7.1.2 (11D257) 的 iPhone 上测试 6.1 版本时，应用程序可以正常注册通知，并在用户上传图片时回显设备 token 。但是当我在 iPad 版本 9.3.5 (13G36) 上运行它时，XCode 控制台显示 registerForRemoteNotificationTypes: iOS 8.0 及更高版本不支持。 并且上传到 iPad 的图片仅显示 0，其中设备 token 应该是。

尝试一下:

   if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
    {
        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    }
    else
    {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
    }

希望对你有帮助。
