Ios 生成的APNS设备令牌不正确

我集成了苹果推送通知，在我的应用程序中遇到了一个奇怪的问题。当我通过usb连接通过Xcode直接安装应用程序时，设备令牌被正确地存储在数据库中，推送通知工作正常。但是，当我创建IPA并通过在同一设备中创建的IPA安装应用程序时，设备令牌生成错误，推送通知不起作用。下面是我的代码：

if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    [[UIApplication sharedApplication] registerUserNotificationSettings:      [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
} else {
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
                             (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

application.applicationIconBadgeNumber = 0;

#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings
        *)notificationSettings {
    [application registerForRemoteNotifications];
}
#endif


- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData
    *)deviceToken {
      const unsigned *tokenData = deviceToken.bytes;
                    NSString *deviceTokenString = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x", ntohl(tokenData[0]),ntohl(tokenData[1]),ntohl(tokenData[2]),ntohl(tokenData[3]),ntohl(tokenData[4]),ntohl(tokenData[5]),ntohl(tokenData[6]),ntohl(tokenData[7])];
     [[NSUserDefaults standardUserDefaults]setObject:deviceTokenString forKey:@"devicetoken"];
      NSLog(@"Device Token = %@", deviceTokenString);
}

//Failed to Register for Remote Notifications
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"Error in registration. Error: %@", error);
}

设备令牌取决于应用程序的签名证书。如果直接安装，则它是dev证书，而在为AdHoc签名时，它是分发证书。对于推送，您需要在服务器上打包相应的分发或开发证书。

通常情况下就是这样。但也可以设置为直接安装为带有临时证书的临时版本。（我自己正在以这种方式调试ad-hoc推送通知。比创建ad-hoc版本、上载到apple等更快。问题是，如果直接作为ad-hoc安装，它不允许进行调试。（应用程序在几秒钟后关闭。但是，我仍然可以打开设备并查看控制台输出）。
