注意事项：
- 需要打开通知权限，
- 推送证书、设置info.plist文件，设置自动生成的 .entitlements文件

3.上传payload和device token到APNS
（1、服务器有两种方式建立和apns的安全连接（token和证书）
（2、服务器发送POST请求：必须包含以下信息
（3、证书建立连接的话：证书和CSR文件绑定，CSR文件作为私钥加密证书，证书当做公钥用来和APNS交互。我们服务器安装这两种证书,证书有效期1年。
The JSON payload that you want to send
The device token for the user’s device
Request-header fields specifying how to deliver the notification
For token-based authentication, your provider server’s current authentication token（大多是证书）
