先看下整个json数据的格式,如下:
工程结构图如下:

1,先把SBJSON-Clssses这个文件夹导入工程里面
2,添加DataSource.h 与 DataSource.m到工程中
3、调用,在ViewController.h添加如下代码:
4、在在ViewController.m添加如下代码:
运行程序,打印结果如下:

工程结构图如下:
[img]
[/img]
1,先把SBJSON-Clssses这个文件夹导入工程里面
2,添加DataSource.h 与 DataSource.m到工程中
@interface DataSource : NSObject //becarefull NSString is a object +(id)dataSource:(NSString *)str; +(id)dataSourceFromUrl:(NSString *)url; @end
#import "JSON.h" #import "DataSource.h" @implementation DataSource //解析本地json数据 +(id)dataSource:(NSString *)str { //获取文件路径 NSString * path = [[NSBundle mainBundle] pathForResource:str ofType:@""]; //获取数据 NSData * reader = [NSData dataWithContentsOfFile:path]; //转换成NSString NSString * JSONString = [[NSString alloc] initWithData:reader encoding:NSUTF8StringEncoding]; return [JSONString JSONValue]; } //解析网络json数据,传入url +(id)dataSourceFromUrl:(NSString *)url{ NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]]; //获取数据 NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; //转换成NSString NSString * JSONString = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; return [JSONString JSONValue]; } @end
3、调用,在ViewController.h添加如下代码:
#import <UIKit/UIKit.h> @interface ViewController : UIViewController { NSDictionary * myData; } @property (retain, nonatomic) NSDictionary * myData; @end
4、在在ViewController.m添加如下代码:
// // ViewController.m // JsonTestCao // // Created by 张 志亮 on 13-1-3. // Copyright (c) 2013年 张 志亮. All rights reserved. // #import "ViewController.h" #import "DataSource.h" @interface ViewController () @end @implementation ViewController @synthesize myData; - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. //这是模拟操作json解析,用的是本地的json数据 //获取数据源 // NSString *str = @"jsondata"; // myData = [DataSource dataSource:str]; // NSInteger numbers = [[myData valueForKey:[[myData allKeys] objectAtIndex:0]] count]; // NSString *sectionNanme = [[myData allKeys]objectAtIndex:1]; // NSString *name = [[myData valueForKey:sectionNanme]objectAtIndex:0]; // NSLog(@"%d",[myData count]); // NSLog(@"%d",numbers); // NSLog(@"%@",sectionNanme); // NSLog(@"%@",name); //获得url NSString *url = @"http://www.dianxiaor.com/getrinfos.php?lng=116.372684&lat=39.993995#jsonNav_l"; //获得数据 myData = [DataSource dataSourceFromUrl:url]; NSLog(@"%d",[myData count]); //获得status NSString *status = [myData valueForKey:@"status"]; NSLog(@"%@",status); //获得msg NSString *msg = [myData valueForKey:@"msg"]; NSLog(@"%@",msg); //获得list的长度 NSInteger countList = [[myData valueForKey:@"list"]count]; NSLog(@"%d",countList); //获得rid NSString *rid = [[[myData valueForKey:@"list"]objectAtIndex:0]valueForKey:@"rid"]; NSLog(@"%@",rid); //获得address NSString *address = [[[myData valueForKey:@"list"]objectAtIndex:0]valueForKey:@"address"]; NSLog(@"%@",address); //获得discounts count 8 NSInteger discounts = [[[[myData valueForKey:@"list"]objectAtIndex:0]valueForKey:@"discounts"]count]; NSLog(@"discounts==%d",discounts); //获得list第一项里面discounts里面所有的dimg NSString *dimg = [[[[myData valueForKey:@"list"]objectAtIndex:0]valueForKey:@"discounts"]valueForKey:@"dimg"]; //this is all dimg for "objectAtIndex:0" and "discounts" NSLog(@"dimg==%@",dimg); //获得list第一项里面discounts里面,一共有8项 第一项的dimg的值 NSString *firstDimg = [[[[[myData valueForKey:@"list"]objectAtIndex:0]valueForKey:@"discounts"]objectAtIndex:0]valueForKey:@"dimg"]; NSLog(@"firstDimg=%@",firstDimg); } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end
运行程序,打印结果如下:
