的IOS目标C解析JSON [英] ios objective c parsing json

问题描述

尝试解析此json，似乎无法弄清楚.

Trying to parse this json and cannot seem to figure it out.

{ description =描述变式1"; id = 4; 价格="25.0"; }， { description ="Variant 2 Description"; id = 5; 价格="50.0"; }， { description ="Variant 3 Description"; id = 6; 价格="75.0"; }

{ description = "Description Variant 1 "; id = 4; price = "25.0"; }, { description = "Variant 2 Description "; id = 5; price = "50.0"; }, { description = "Variant 3 Description"; id = 6; price = "75.0"; }

这是我的代码，但是我在NSLog上得到了一个SigAbt:

Here is my code, but I get a SigAbt on the NSLog:

- (NSMutableArray *) getVariants:(NSString *)variantJson 
{
    NSMutableArray *variants = [[NSMutableArray alloc] init];
    NSLog(@"Variant JSON: %@", variantJson);

    NSArray *vars = [variantJson valueForKeyPath:@"variants"];

    for (id var in vars) 
    {
        NSLog(@"description: %@",[var objectForKey:@"description"]);

    }

    return variants;
}

传入变量json的变量:variantJson是上面发布的JSON.

The json coming in to variable: variantJson is the above posted JSON.

推荐答案

iOS不会透明地解析JSON.您需要通过实际的JSON解析器库(例如 SBJson )运行字符串. (BSD许可)或者您可以使用内置的

iOS doesn't parse JSON this transparently; you need to run your string through an actual JSON parser library, like SBJson. (BSD-licensed) Or you can use the built-in NSJSONSerialization if you're targeting OS 5 or later.
