在项目中与服务器交互的时候,经常要遇到解析json的情况,如果有同学想要解析JSON,那么JSONKit可以是一个不错的选择

首先可以去gitHub上下载JSONKit 地址:JSONKit

放入工程以后,把JSONKit设置为不支持arc的模式

然后在点m修改2个地方

//array->isa      = _JKArrayClass;    object_setClass(array, _JKArrayClass);//    dictionary->isa      = _JKDictionaryClass;      object_setClass(dictionary, _JKDictionaryClass);

原因是isa已经被废弃了，所以请调用object_setClass()和object_getClass()函数来搞定

这里特别设置了2个json串,供大家参考学习

arr.conf

[{"preview_sub": "adornment_fly_1_100.png", "width": "300", "path": "adornment_fly_1.png", "name": "adornment_fly_1.png", "height": "300"}, {"preview_sub": "adornment_fly_2_100.png", "width": "300", "path": "adornment_fly_2.png", "name": "adornment_fly_2.png", "height": "300"}]

dict.conf

{"status": "ok", "after": "14851", "before": "11011"}

NSString *res = nil;        //数组转json串    NSArray *arr = [[NSArray alloc] initWithObjects:@"One",@"Two",@"Three",nil];    res = [arr JSONString];    NSLog(@"res= %@", [NSString stringWithString: res]);        //字典类型（对象）转json串    NSArray *arr1 = [NSArray arrayWithObjects:@"dog",@"cat",nil];    NSArray *arr2 = [NSArray arrayWithObjects:[NSNumber numberWithBool:YES],[NSNumber numberWithInt:30],nil];    NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:arr1,@"pets",arr2,@"other",nil];    res = [dic JSONString];    NSLog(@"res= %@", [NSString stringWithString: res]);        //json串转数组    NSString* arrConf = [[NSString alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"arr" ofType:@"conf"] encoding:NSUTF8StringEncoding error:nil];    NSArray *ConfArr = [arrConf objectFromJSONString];    NSLog(@"%@",ConfArr);        //json串转字典    NSString* dicConf = [[NSString alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"dict" ofType:@"conf"] encoding:NSUTF8StringEncoding error:nil];    NSArray *ConfDic = [dicConf objectFromJSONString];    NSLog(@"%@",ConfDic);
