将 userInfo 添加到 NSURLConnection

对于我正在开发的一个项目，我需要使用 NSURLConnection 进行多个同时的 plist 上传，并且如果有一个 userInfo 属性来跟踪内容，那就太好了。

我有：

// header
@interface NSURLConnection ()

@property (nonatomic, retain) id userInfo;

@end

// implementation
@implementation NSURLConnection ()

@synthesize userInfo = _userInfo;

@end

当我尝试编译时，它说它需要括号中的标识符。当我给它一个标识符，使其成为一个类别时，我想在该类别中进行综合会变得令人难以置信的冒犯。当我完全删除括号时，最糟糕的噩梦发生了：它编译了。不幸的是， NSURLConnection 变得不明确，我的覆盖了真实的。它非常适合保存 userInfo，但绝对没有其他用途。

有人成功做到这一点吗？

For a project I'm working on, I need to be doing several simultaneous plist uploads with an NSURLConnection, and it'd be neat to have a userInfo property to keep track of stuff.

I have:

// header
@interface NSURLConnection ()

@property (nonatomic, retain) id userInfo;

@end

// implementation
@implementation NSURLConnection ()

@synthesize userInfo = _userInfo;

@end

When I try to compile, it says it expects an identifier in the parens. When I give it an identifier, making it a category, it becomes incredibly offended that I want to synthesize in the category. When I remove the parens entirely, the worst nightmare occurs: it compiles. Unfortunately, NSURLConnection becomes ambiguous, with mine overwriting the real one. It's great at holding userInfo, but absolutely nothing else.

Has anyone successfully done this?
