通知实战设置通知图片(iOS10以后的)

解释两个基本扩展（`Notification Content`、`Notification Service`）

Notification Content其实是用来自定义长按通知显示通知的自定义界面

Notification Service是用来处理远程通知的，我们可以在远程通知到来之际，我们在Notification Service

里面由30s的时间来处理这条通知的

首先使用Notification Service

1.创建扩展target

2. 这里会新建一个扩展的target,新的target需要新的ID,新的证书等(证书和id不会的请百度)

3.然后对主target进行设置

注意如果没有用到后台的播放什么的只选Remote notifications，免得被拒绝 通知实战设置通知图片(iOS10以后的)

4. 对扩展的target进行设置

5.这里用的是极光推送,需要极光的相关文件(需要文件的可以去极光开发中心获取demo)

6.扩展target添加文件

7.当添加后为了可以访问http,在对应的plist文件进行设置

8.设置完成之后就可以看代码了
