iOS端推送回传点击数据异常

问题描述：iOS客户端初始化友盟推送，增加延迟函数5s造成点击回传数据失败

操作步骤：

1.在App杀死状态下，点击远端推送进入App

2.在didFinishLaunchingWithOptions中增加5秒延迟函数，再去调用推送注册方法，代码如下。

会造成点击数据回传失败，麻烦解释下友盟这边是做了什么特殊处理吗，谢谢

@interface AppDelegate ()<UNUserNotificationCenterDelegate>

@property (nonatomic, strong) NSDictionary *launchOptions;

@end


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {


      self.launchOptions = launchOptions;

      __weak __typeof__(self) weakSelf = self;

      dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            [weakSelf setupUmengPush];
      });  

     return YES;
}

- (void)setupUmengPush{
       UMessageRegisterEntity * entity = [[UMessageRegisterEntity alloc] init];
       entity.types = UMessageAuthorizationOptionBadge | UMessageAuthorizationOptionAlert | UMessageAuthorizationOptionSound;
       [UNUserNotificationCenter currentNotificationCenter].delegate = self;
       [UMessage registerForRemoteNotificationsWithLaunchOptions:self.launchOptions Entity:entity completionHandler:^(BOOL granted, NSError * _Nu   llable error) {
 
       }];
}
