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
