注册我的应用程序的mime-type /等

Question

在检查了几个问题，遵循了许多在线教程后，我仍然无法让我的应用程序注册我的mime类型。我觉得这里一定有一些我还没有意识到的魔力。除了修改我的plist文件之外，还有其他步骤吗？还是我看错了？

我唯一觉得可能是一个额外的问题是，我已经更改了我的项目名称，并且可能有一些东西与构建设置和/或配置文件不一致？它是存档的，我可以安装用于临时分发，我只是不能在电子邮件中获得文件来注册应用程序。

该文件是我使用NSJSONSerialization准备的JSON数据。

这是我的plist：

尝试将此代码添加到应用程序的delegate.m文件中。在

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

  NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];
    if (url != nil && [url isFileURL]) {}
}

这对我的音频附件起作用了，但我的图像文件有问题。jpg、png、tif等
