天气预报demo （ShareREC 官网 MobAPI）

第一步 自己注册一个应用，然后获取里面的 App Key，下载MobAPI SDK

然后拖入 MobAPI.framework 和 MOBFoundation.framework 到你的项目中

官网是 ： http://www.mob.com

第二步  导入libraries  文件

第三步 ：  新建一个 UIViewController 控制器  －－－ WeatherMainViewController

然后在  AppDelegate.m 里面写入如下  要导入

#import "WeatherMainViewController.h"

#import <MobAPI/MobAPI.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    self.window.backgroundColor = [UIColor whiteColor];
    // 1. 首页
    WeatherMainViewController *weather = [[WeatherMainViewController alloc] init ];
    self.window.rootViewController = weather;
    [self.window makeKeyAndVisible];
    
    [MobAPI registerApp:@"1ab37d5dsa3a3c"];
    return YES;
}

注意： 1ab37d5dsa3a3c 是你的 App Key

   第四：根据api文档获取里面的字段和返回参数取值

   他的返回参数是
