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

 1 #import "ViewController.h"
 2 #import "Student.h"
 3 #import "GDataXMLNode.h"
 4 #import "JSONKit.h"
 5
 6 @interface ViewController () <NSXMLParserDelegate>

 8 /**
 9  *  存储数据的数组
10  */
11 @property (nonatomic, strong) NSMutableArray *dataArray;
12
13 @end
14
15 @implementation ViewController
16
17 - (void)viewDidLoad {
18     [super viewDidLoad];
19     // Do any additional setup after loading the view, typically from a nib.
20 }
21
22 #pragma mark - 使用JSONKit解析json数据
23 - (IBAction)jsonkitParserActionJSONDocument:(UIButton *)sender {
24
25     // 1.获取文件路径
26     NSString *path = [[NSBundle mainBundle] pathForResource:@"StudentInfo_json.txt" ofType:nil];
27
28
29     // 2.根据路径获取NSData
30     NSData *data = [NSData dataWithContentsOfFile:path];
31
32
33     // 3.对存储数据的数组进行初始化
34     self.dataArray = [NSMutableArray array];
35
36
37     // 4.开始进行解析
38     NSArray *resultArray = [data objectFromJSONData];
39
40
41     // 5.遍历数组，取出其中的字典，然后使用KVC给对象赋值
42     for (NSDictionary *dict in resultArray) {
43
44         Student *stu = [[Student alloc] init];
45
46         // 将数组中的值赋给对象
47         [stu setValuesForKeysWithDictionary:dict];
48
49         // 将对象添加到数组中
50         [self.dataArray addObject:stu];
51     }
52
53
54     // 遍历检验
55     for (Student *stu in self.dataArray) {
56         NSLog(@"name = %@, gender = %@, age = %ld, hobby = %@", stu.name, stu.gender, stu.age, stu.hobby);
57     }
