我已经定义了我的应用程序支持的 UTI，并且可以将它们拖到 Dock 图标上。我还在我的应用程序委托中实现了 -application:openFiles: 和 -application:openFile: 。但是，当我获得有关我支持的 UTI 项目的信息时，它不会显示在列表中，并且在我浏览到“其他”时显示为灰色。我从下面的 plist 中粘贴了一个示例 UTI。我可能做错了什么？我特别希望它能够与内置的 App Store 集成一起使用。

更新

我启动了一个虚拟机，除了安装我自己的应用程序之外没有任何第三方应用程序，并且一切都按预期工作。我已经像这样重建了我的 LaunchServices 数据库：

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.fra‌​mework/Support/lsregister -kill -r -domain local -domain system -domain user ; killall Dock

这没有任何区别。然后，我使用此命令对 LaunchServices 数据库进行了转储，并在其下方显示了我的应用程序包的结果。这对我来说看起来很合理，但我不确定我在寻找什么。我是否可能与系统上的其他应用程序发生某种类型的冲突？如果是这样，我将如何解决这个问题？

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.fra‌​mework/Support/lsregister -dump >>lsregister.txt

转储：

您可以将您的应用程序设置为默认为代码中的特定文档类型启动的应用程序。我发现这在某些情况下是必要的，因为在 info.plist 中设置链接还不够。这通常在您的应用控制器的 +initialize 方法中：

    //First Check if our app is the default application to open .cbz files
NSString *cbzUTI = (NSString *)CFBridgingRelease(UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension,
                                                                                          (CFStringRef)@"cbz",
                                                                                          NULL));
NSString *currentCbzApp = (NSString *)CFBridgingRelease(LSCopyDefaultRoleHandlerForContentType((__bridge CFStringRef)cbzUTI, kLSRolesAll));

if ([currentCbzApp caseInsensitiveCompare:@"com.abbey-code.AppName"] != NSOrderedSame) {
    //If not, then first register it in Launch Services
    LSRegisterURL((__bridge CFURLRef)[[NSBundle mainBundle] executableURL], YES);
    //Second set it as the default handler for the file type
    LSSetDefaultRoleHandlerForContentType((__bridge CFStringRef)cbzUTI, kLSRolesAll,(__bridge CFStringRef) [[NSBundle mainBundle] bundleIdentifier]);
}
