ios - 个别设备获取不到token

Question

我们项目需要获取用户设备的deviceToken，发现证书配置都正确，并且开启时候也是有给予设置允许通知的权限。但是个别终端还是无法获取到token，有的却可以。请教下这个是什么原因会导致个别可以个别不行？（网络环境都相同）

Answer 1

I happened to encounter the same problem as the original poster today. I can get the token on 5s, but not on 6s.

原因如下：
    我在 didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中判断是否登录的时候提前使用了 return YES  导致整个方法没有执行完，我把return去掉就解决问题了。
代码如下：
    //注册代码
        [JPUSHService registerForRemoteNotificationTypes:(UIUserNotificationTypeBadge |
                                                  UIUserNotificationTypeSound |
                                                  UIUserNotificationTypeAlert)
                                                  categories:nil];
    
        //导致有些设备获取不了token，有些设备能够获取token的代码
        if(![kUSER_DEFAULT boolForKey:kIS_LOGIN])
        {
            LoginViewController *loginVC   = [[LoginViewController alloc] init];
            self.window.rootViewController = loginVC;
            return YES; （把此return YES 删除）
        }
        return YES
        
    //获取token代码
    -(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
    {
        HSLog(@"DeviceToken:%@", deviceToken]);
    }

Answer 2

didFailToRegisterForRemoteNotificationsWithError Is there any hint in this callback? Also, which version of iOS is your device on? Is it easy to post the code for registering APN?
