基于plist创建我自己的文件扩展名

Question

我的应用程序处理*.mndl类型的文件，该文件不超过自定义*.plist。 到目前为止，我一直在使用*.plist个文件，但现在我想关联扩展程序并能够从任何其他应用程序打开*.mndl文件我已经意识到将file.plist重命名为{{ 1}}不起作用。 （因此，我甚至不知道我是否正确地执行了扩展关联和导出事项）

我从计算机发送了一个文件file.mndl，当我收到mail.app时，我得到了 file.mndl（它自动重命名，重置我的iPad时发生了这种情况）

如何在能够使用NSDictionary类中的file.mndl.plist读取其内容的同时创建自己的mndl文件？

即使我正在使用iOS，我相信这种东西都是从MacOS和Cocoa移植过来的。所以Cocoa开发人员也可以知道这一点。

感谢您的意见/答案。

ANSWERED： 仅用于完成目的这是我对info.plist的补充：

+dictionaryWithContentsOfFile:

Answer 1

至少对于Cocoa（桌面）应用程序，您需要将以下信息添加到应用程序的Info.plist中。

http://www.markdouma.com/developer/nacho.plist

显然，您应该将统一类型标识符更改为适当的标识符。 （我通常做com.markdouma.something，因为那是我的网站）。

请注意，如果您计划通过创建NSDocument子类来处理加载文件来计划使用Cocoa的NSDocument体系结构，那么您只想为NSDocumentClass指定一个条目。否则，你总是可以实现以下＆lt; NSApplicationDelegate＆gt; （读作应用程序委托协议）方法：

- (void)application:(NSApplication *)sender openFiles:(NSArray *)filenames;

这将为您提供一个NSArray NSStrings，表示用户在Finder中双击的文件的POSIX路径（或拖动到应用程序图标等）

如果要转到NSDocument路由，可以覆盖以下NSDocument方法

- (BOOL)readFromURL:(NSURL *)url ofType:(NSString *)type error:(NSError **)outError;

用[[NSDictionary dictionaryWithContentsOfFile：[url path]] retain]创建你的字典;

希望这会有所帮助......

最终我发现了这个也可以用作参考： 我在Google的缓存中找到了这个，它显示了如何添加具有不同属性的多个扩展：）
