IOS通过PushSharp开源框架发送推送

1，首先生成推送证书：

openssl x509 -in aps_developer_identity.cer -inform DER -out aps_developer_identity.pem -outform PEM

openssl pkcs12 -nocerts -out PushChat_Noenc.pem -in PushChatKey.p12

（cat aps_developer_identity.pem PushChat_Noenc.pem > ck.pem）

openssl pkcs12 -export -in aps_developer_identity.pem -inkey PushChat_Noenc.pem -certfile PushChat.certSigningRequest -name "aps_developer_identity" -out aps_developer_identity.p12 （C#必须）

2.下载框架http://pan.baidu.com/s/1pJoD8IR或者https://github.com/Redth/PushSharp

3.调用方法

4，我遇到的异常The maximum number of Send attempts to send the notification was reached!

可以修改

FeedbackService.cs和 ApplePushChannel.cs中的System.Security.Authentication.SslProtocols.Ssl3为System.Security.Authentication.SslProtocols.Tls两处即可
