NSMutableDictionary正在为键和值添加引号-为什么? [英] NSMutableDictionary is adding quotes to keys and values - why?

问题描述

我正在尝试使用以下方法向NSMutableDictionary中添加一些其他键/值对:

I'm trying to add some additional key/value pairs to an NSMutableDictionary, using:

Tag *tag1 = [results1 objectAtIndex:0];
[resultsDict setObject:[tag1 retrieveTextUpToDepth:1] forKey:@"image_url"];

Tag *tag2 = [results2 objectAtIndex:0]; 
[resultsDict setValue:[tag2 retrieveTextUpToDepth:1] forKey:@"majority"];

这毫无疑问地添加了k/v对，除了当我检索它们时，某些值已经用双引号引起来了:

This adds the k/v pairs with no problem, except when I come to retrieve them, some of the values have been wrapped with double quotes:

po extendedDataDictionary:

    "image_url" = "/images/mpsL/11727.jpeg";
    majority = 3460;

键和值都是NSString，不带引号-因此，我很困惑它们的出现位置.

Both keys and values are NSStrings, with no quotes - so I'm stumped as to where they're appearing from.

有什么办法可以防止这种情况?

Is there any way of preventing this?

还是我必须忍受它，并在检索到值后尝试删除引号?

Or am I going to have to live with it and try to strip off the quotes once I've retrieved the value?

谢谢...

推荐答案

引号实际上不是内容的一部分； -description方法(由IIRC称为po)只是将内容包装在引号中以供显示，这些引号中包含非字母数字字符.

The quotes aren't really part of the content; the -description method (called by po, IIRC) simply wraps things in quotes for display that have non-alphanumeric characters in them.
