将NSDictionary解析为包含自定义分隔符的字符串 [英] Parse NSDictionary to a string with custom separators

问题描述

我有一个带有一些值的NSMutableDictionary，我需要将键和值连接成一个字符串，所以

I have an NSMutableDictionary with some values in it, and I need to join the keys and values into a string, so

> name = Fred
> password = cakeismyfavoritefood
> email = [e-mail]

变为 name = Fred& password = cakeismyfavoritefood& ; email=[e-mail]

我该怎么做？有没有办法将 NSDictionaries 加入字符串？

How can I do this? Is there a way to join NSDictionaries into strings?

推荐答案

你可以轻松地枚举字典键和对象：

You can easily do that enumerating dictionary keys and objects:

NSMutableString *resultString = [NSMutableString string];
for (NSString* key in [yourDictionary allKeys]){
    if ([resultString length]>0)
       [resultString appendString:@"&"];
    [resultString appendFormat:@"%@=%@", key, [yourDict objectForKey:key]];
}
