JSONKit解析json数据

先将第三方文件拖进工程

JSONKit.h和JSONKit.m

然后设置在ARC工程中添加MRC文件，如下图所示

 #import "ViewController.h"

 #import "Student.h"

 #import "GDataXMLNode.h"

 #import "JSONKit.h"

 @interface ViewController () <NSXMLParserDelegate>

 /**

  *  存储数据的数组

  */

 @property (nonatomic, strong) NSMutableArray *dataArray;

 @end

 @implementation ViewController

 - (void)viewDidLoad {

     [super viewDidLoad];

     // Do any additional setup after loading the view, typically from a nib.

 }

 #pragma mark - 使用JSONKit解析json数据

 - (IBAction)jsonkitParserActionJSONDocument:(UIButton *)sender {

     // 1.获取文件路径

     NSString *path = [[NSBundle mainBundle] pathForResource:@"StudentInfo_json.txt" ofType:nil];

     // 2.根据路径获取NSData

     NSData *data = [NSData dataWithContentsOfFile:path];

     // 3.对存储数据的数组进行初始化

     self.dataArray = [NSMutableArray array];

     // 4.开始进行解析

     NSArray *resultArray = [data objectFromJSONData];

     // 5.遍历数组，取出其中的字典，然后使用KVC给对象赋值

     for (NSDictionary *dict in resultArray) {

         Student *stu = [[Student alloc] init];

         // 将数组中的值赋给对象

         [stu setValuesForKeysWithDictionary:dict];

         // 将对象添加到数组中

         [self.dataArray addObject:stu];

     }

     // 遍历检验

     for (Student *stu in self.dataArray) {

         NSLog(@"name = %@, gender = %@, age = %ld, hobby = %@", stu.name, stu.gender, stu.age, stu.hobby);

     }

 }
