JSON解析数据.
这里是新建一个JSONParser类, 先新建一个方法,然后在是在方法里面进行解析,然后在根试图中执行解析方法
MainViewController.m
#import "MainViewController.h" #import "XMLSAXParser.h" #import "JSONParser.h" @interface MainViewController () @end @implementation MainViewController - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. self.view.backgroundColor = [UIColor cyanColor]; //开始执行JSON方法 JSONParser *json = [[JSONParser alloc] init]; [json startJSONParser]; [json release]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } /* #pragma mark - Navigation // In a storyboard-based application, you will often want to do a little preparation before navigation - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { // Get the new view controller using [segue destinationViewController]. // Pass the selected object to the new view controller. } */ @end
JSONParser.h
#import <Foundation/Foundation.h> @interface JSONParser : NSObject //json方法 - (void)startJSONParser; @end
JSONParser.m
#import "JSONParser.h" #import "Student.h" @implementation JSONParser - (void)startJSONParser { //系统提供额JSON解析方法 NSString *strPath = [[NSBundle mainBundle] pathForResource:@"Student" ofType:@"txt"]; NSData *data = [NSData dataWithContentsOfFile:strPath]; //参数1:文件数据路径信息 //参数2:设置解析的结果 //参数3:错误信息 NSError *error = nil; NSArray *array = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error]; NSLog(@"%@", array); for (NSDictionary *dic in array) { Student *stu = [[Student alloc] init]; stu.name = [dic objectForKey:@"name"]; stu.sex = [dic objectForKey:@"sex"]; stu.phone = [dic objectForKey:@"phone"]; stu.number = [dic objectForKey:@"number"]; } } @end
