• 首先創建一個Header File ， 在其中寫入URL

前兩段代碼為格式，因為URL開頭的格式都是以前兩段代碼為開始，所以寫入之后以后直接輸入#define+URL就可以了。

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

-(void)getData{
    //    //cityId:城市ID
    //    //lat:緯度
    //    //lng:經度
    //showType
    //sendPrice
    // defaultOeder
   //實例化一個字典 
    NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
    // 在字典中寫入key
    NSDictionary *userInfo = [[NSUserDefaults standardUserDefaults] objectForKey:@"UserInfo"];
    //向dic中傳值
    [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];// 提示用戶正在請求
    [[SetRequest sharedInstance]postRequestWithURL:URL(*********輸入URL)
    postParems:dic content:^(NetWorkModel *model){        
        [MBProgressHUD hideAllHUDsForView:self.view animated:YES];
        if(model.error){            
            NSLog(@"獲取列表失敗");
        }else{            
            if ([model.responseDic[@"error_code"] intValue] == 0) {                      
               _dataSource = model.responseDic[@"restaurantList"];                
                [_tableView reloadData];                
            }
        }
    }];
}
