objective-c - 应用程序未显示在支持文档类型的 "Open With"菜单中

Question

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(delegate)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，它没有显示在列表中，并且在我浏览到“其他”时呈灰色显示。我从下面的 plist 中粘贴了一个示例 UTI。我做错了什么？我特别希望它与内置的 App Store 集成一起使用。

更新

我启动了一个虚拟机，除了我自己安装的应用程序外，没有第三方应用程序，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

那没有什么区别。然后，我使用此命令转储了 LaunchServices 数据库，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。我是否可能遇到与系统上其他应用程序的某种类型的冲突？如果是这样，我将如何解决？

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

您可以将您的应用程序设置为在代码中针对特定文档类型默认启动的应用程序。我发现在某些情况下这是必要的，因为在 info.plist 中设置链接是不够的。这通常在您应用 Controller 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]);
}
