Json字符串转换为NSDictionary

首先看字符串

{

    res =     (

        "Teacher Site",

        "http://xxx.com/"

    );

}

我们需要将字符串变换称如下字符串才可以转换成功

{

    "res" :[

        "Homework",

        "http://xxx.com/"

    ]

}

具体代码如下：

        NSString *resTmpStr=[resStr stringByReplacingOccurrencesOfString:@"res =     (" withString:@"\"res\":["];
        resTmpStr=[resTmpStr stringByReplacingOccurrencesOfString:@");" withString:@"]"];
        resTmpStr=[resTmpStr stringByReplacingOccurrencesOfString:@"Homework" withString:@"\"Homework\""];
        NSData* data1 = [resTmpStr dataUsingEncoding:NSUTF8StringEncoding];
        __autoreleasing NSError* error = nil;
        NSDictionary *res = [NSJSONSerialization JSONObjectWithData:data1 options:kNilOptions error:&error];
        if (error != nil) {
            NSLog(@"convert error");
            continue;
        };
        
        NSArray *data = [res objectForKey:@"res"];
        if (data != nil) {
            if (result == nil) {
                result = [[NSMutableArray alloc] init];
            }
            Resource *tmp = [[Resource alloc] init];
            tmp.schoolName = data[0];
            tmp.url = data[1];
            if (data.count > 2) {
                tmp.userName = data[2];
                tmp.password = data[3];
            }
            [result addObject:tmp];
        }
