具体实现步骤如下：
1.ios应用程序中允许向客户推送消息
2.需要有苹果的证书以及密码（怎么获取，网上搜一下，需要交费的）
3.phone手机一部，安装了该ios应用程序
4..net 项目中引用PushSharp.Apple.dll,PushSharp.Core.dll(这两个文件在网上搜一下，有源码的)
5.开始写代码，定义全局的对象PushBroker pusher = new PushBroker();
6.注册方法：
代码如下:
protected void startApp()
{
pusher.RegisterAppleService(new ApplePushChannelSettings(File.ReadAllBytes(CertificatePath), CertificatePassword));
pusher.OnDeviceSubscriptionChanged += pusher_OnDeviceSubscriptionChanged;
pusher.OnDeviceSubscriptionExpired += pusher_OnDeviceSubscriptionExpired;
pusher.OnNotificationSent += pusher_OnNotificationSent;
pusher.OnNotificationFailed += pusher_OnNotificationFailed;
}
static void pusher_OnNotificationFailed(object sender, INotification notification, Exception error)
{
var n = (AppleNotification)notification;
//error.Message ...获取推送出错的信息
Log.Error("推送出错的信息", error);
}
static void pusher_OnNotificationSent(object sender, INotification notification)
{
//消息推送成功后
var n = (AppleNotification)notification;
//n.Payload.Alert.Body 获取推送的消息内容...
Log.Error("推送内容"+n.Payload.Alert.Body);
}
static void pusher_OnDeviceSubscriptionExpired(object sender, string expiredSubscriptionId, DateTime expirationDateUtc, INotification notification)
{
// 从数据库删除过期的expiredSubscriptionId
}
static void pusher_OnDeviceSubscriptionChanged(object sender, string oldSubscriptionId, string newSubscriptionId, INotification notification)
{
// 把数据库中的oldSubscriptionId更新为newSubscriptionId
}
startApp()方法中有两个参数：
CertificatePath：证书的路径 CertificatePassword：密码
7.推送代码：
代码如下:
pusher.QueueNotification(new AppleNotification().ForDeviceToken(TokenID) .WithAlert("推送的内容").WithBadge(1).WithSound("default"));// 从数据库或者其他等地方获取设备的TokenID，每个iphone一个TokenID
8.如果想在Android设备上推送，项目要引进PushSharp.Android.dll，代码的话后期会为大家更新，敬请关注！
