我已经定义了我的应用支持的UTI，并可以将它们拖到Dock图标上。我还实现了-application：openFiles：和-application：openFile：在我的app委托中。但是当我获得我支持的UTI项目的信息时，它不会显示在列表中，当我浏览到＆＃34;其他＆＃34;时会显示为灰色。我从下面的plist粘贴了一个样本UTI。我能做错什么？我特别希望它能够与内置的App Store集成一起使用。

更新
我启动了一个没有我自己安装的第三方应用程序的虚拟机，一切都按预期工作。我重建了我的LaunchServices数据库，如下所示：
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user ; killall Dock
这没有任何区别。然后我使用此命令转储LaunchServices数据库，其下方的应用程序包的结果。这看起来很合理，但我不确定我在寻找什么。我是否有可能遇到与我系统上其他应用程序发生某种冲突的情况？如果是这样，我该如何解决？
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -dump >>lsregister.txt

您可以将应用程序设置为默认情况下为代码中的特定文档类型启动的应用程序。我发现在某些情况下，在info.plist中设置链接是不够的，这是必要的。 这通常是在你app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]);
}
