访问接口

• 首先创建一个Header File ， 在其中写入URL

前两段代码为格式，因为URL开头的格式都是以前两段代码为开始，所以写入之后以后直接输入#define+URL就可以了。

#define IP @"http://dalianmohekeji.eicp.net:8102/repastmanage"
#define URL(api)   [ NSString stringWithFormat:@"%@%@",IP,api]
 #define ******* (输入URL)@"/clientAPI/searchRestaurantList.json"

-(void)getData{
    //    //cityId:城市ID
    //    //lat:纬度
    //    //lng:经度
    //showType
    //sendPrice
    // defaultOeder
   //实例化一个字典 
    NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
    // 在字典中写入key
    NSDictionary *userInfo = [[NSUserDefaults standardUserDefaults] objectForKey:@"UserInfo"];
    //向dic中传值
    [dic setValue:userInfo[@"supermaketName"] forKey:@"supermaketName"];
    [dic setValue:userInfo[@"tasteCategory"] forKey:@"tasteCategory"];
    [dic setValue:@"0411" forKey:@"ctiyId"];
    [dic setValue:[NSNumber numberWithDouble:121.517977] forKey:@"lng"];
    [dic setValue:[NSNumber numberWithDouble:38.8496481] forKey:@"lat"];
    [dic setValue:userInfo[@"type"] forKey:@"type"];
    [dic setValue:@"1" forKey:@"showType"];
    [MBProgressHUD showHUDAddedTo:self.view animated:YES];// 提示用户正在请求
    [[SetRequest sharedInstance]postRequestWithURL:URL(*********输入URL)
    postParems:dic content:^(NetWorkModel *model){        
        [MBProgressHUD hideAllHUDsForView:self.view animated:YES];
        if(model.error){            
            NSLog(@"获取列表失败");
        }else{            
            if ([model.responseDic[@"error_code"] intValue] == 0) {                      
               _dataSource = model.responseDic[@"restaurantList"];                
                [_tableView reloadData];                
            }
        }
    }];
}
