配置：

1. 注册极光账号并于控制台创建应用，获取对应应用的AppKey
2. 在极光控制台中的推送设置里上传对应推送证书
3. 使用pod 'JPush', '3.0.2' 导入极光推送SDK
4. Xcode设置，target→Capabilities→Push NOtifications→ON
5. Xcode设置，target→Capabilities→Background Modes→ON→Remote notifications打钩

代码：

请将以下代码添加到AppDelegate.m引用头文件的位置。

// 引入JPush功能所需头文件
#import "JPUSHService.h"
// iOS10注册APNs所需头文件
#ifdef NSFoundationVersionNumber_iOS_9_x_Max
#import <UserNotifications/UserNotifications.h>
#endif
// 如果需要使用idfa功能所需要引入的头文件（可选）
#import <AdSupport/AdSupport.h>

为AppDelegate中添加委派。

@interface AppDelegate ()<JPUSHRegisterDelegate>
