ios - APNS 设备 token 生成不正确

Question

我已经集成了苹果推送通知，但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 token 正在生成并正确存储在数据库中并且推送通知工作正常。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 token 生成错误并且推送通知不起作用。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 token 取决于您签署应用程序所使用的证书。如果你直接安装它是开发证书，而当为 AdHoc 签名时它是一个分发证书。对于推送，您需要在服务器上打包相应的分发或开发证书。
