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>

 1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
 2     self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
 3     self.window.backgroundColor = [UIColor whiteColor];
 4     // 1. 首页
 5     WeatherMainViewController *weather = [[WeatherMainViewController alloc] init ];
 6     self.window.rootViewController = weather;
 7     [self.window makeKeyAndVisible];
 8
 9     [MobAPI registerApp:@"1ab37d5dsa3a3c"];
10     return YES;
11 }

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
