ios - IPA 文件未在 iOS 中获取设备令牌

Question

我创建了启用推送通知的配置文件。在设备中安装 IPA 文件后，应用程序未获取设备令牌。有谁知道为什么这个问题出现在我的应用程序中？

Answer 1

在您的应用委托的 didFinishLaunchingWithOptions 添加以下行

[[UIApplication sharedApplication] 

   registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert];

然后将委托功能实现为

  - (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
  {
       NSString *str = [[NSString stringWithFormat:@"%@",deviceToken] stringByReplacingOccurrencesOfString:@"<" withString:@""];
       str=[str stringByReplacingOccurrencesOfString:@">" withString:@""];
       str=[str stringByReplacingOccurrencesOfString:@" " withString:@""];

    //str is your device token and can used now.
   }
