解析自己的json

先将代码记录下来：

- (IBAction)bntPressIOSJson:(id)sender {
    
    NSError *error;
    //加载一个NSURL对象
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://192.168.1.102/test.php"]];
    
    //将请求的url数据放到NSData对象中
    NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    
    //IOS5自带解析类NSJSONSerialization从response中解析出数据放到字典中
    //NSDictionary *weatherDic = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];
    
    NSArray *weatherInfoArray = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];
    
    NSDictionary *weatherInfo = [weatherInfoArray objectAtIndex:0];
    
    //txtView.text = [NSString stringWithFormat:@"今天是 %@  %@  %@  的天气状况是：%@  %@ ",[weatherInfo objectForKey:@"date_y"],[weatherInfo objectForKey:@"week"],[weatherInfo objectForKey:@"city"], [weatherInfo objectForKey:@"weather1"], [weatherInfo objectForKey:@"temp1"]];
    txtView.text = [NSString stringWithFormat:@"查出 %@  %@房间，学号为%@  的同学是：%@  %@ ",[weatherInfo objectForKey:@"gymc"],[weatherInfo objectForKey:@"fjh"],[weatherInfo objectForKey:@"xh"], [weatherInfo objectForKey:@"xm"], [weatherInfo objectForKey:@"xb"]];
    
    for (NSObject *object in weatherInfoArray) {
        NSLog(@"快速的遍历数组对象为: %@",object);
    }
    //NSLog(@"weatherInfo字典里面的内容为--》%@", weatherInfo[0]);
    
}
