最近做公司的一个项目.一旦数据库插入新的消息,就要通知服务器,将这些新的消息推送给苹果客户端,以前我们的项目中有人做过这个功能,无奈做的有点复杂,而且代码没注释,我压根就没看懂.所以自己打算重新搞一个.
小小研究了一个,找到PushSharp这个类库,(超级强大),然后用了下感觉很不错,推荐给大家,为大家介绍下.
一.首先来了解下这几个类库
引用PushSharp 的几个类库
PushSharp.Core:核心库必须引用
PushSharp.Apple:向苹果推送的类库
PushSharp.Android：C2DM及GCM,用于Android设备
PushSharp.Windows：用于Windows 8
PushSharp.WindowsPhone：用于WP设备
PushSharp.Amazon.Adm：用于Amazon的设备
PushSharp.Blackberry：用于黑莓设备
PushSharp.Google.Chrome：用于Chrome
这些类库按照自己的项目要求使用即可
二.简单的示例代码
注意,如果你需要给苹果推送 你首先要给你的APP去注册一个证书,然后在你的APP中写一些代码,来接受推送.
//创建一个推送对象
private PushBroker push=new PushBroker();
//关联推送状态事件
push.OnNotificationSent += NotificationSent;
push.OnChannelException += ChannelException;
push.OnServiceException += ServiceException;
push.OnNotificationFailed += NotificationFailed;
push.OnDeviceSubscriptionExpired += DeviceSubscriptionExpired;
push.OnDeviceSubscriptionChanged += DeviceSubscriptionChanged;
push.OnChannelCreated += ChannelCreated;
push.OnChannelDestroyed += ChannelDestroyed;
var appleCert = File.ReadAllBytes("证书路径");//将证书流式读取
push.RegisterAppleService(new ApplePushChannelSettings(appleCert, "证书密码"));//注册推送通道
push.QueueNotification(new AppleNotification()
.ForDeviceToken(messageList[i].DeviceToken)//手机token
.WithAlert(messageList[i].Message)//推送消息内容
.WithBadge(7)//设备图标显示的未读数(图标右上角的小标志)
.WithSound("sound.caf"));//提示声音
push.StopAllServices()//停止推送服务.
#region=====推送状态事件
static void DeviceSubscriptionChanged(object sender, string oldSubscriptionId, string newSubscriptionId, INotification notification)
{
//Currently this event will only ever happen for Android GCM
//Console.WriteLine("Device Registration Changed: Old-> " + oldSubscriptionId + " New-> " + newSubscriptionId + " -> " + notification);
}
// 推送成功
static void NotificationSent(object sender, INotification notification)
{
}
// 推送失败
static void NotificationFailed(object sender, INotification notification, Exception notificationFailureException)
{
//Console.WriteLine("Failure: " + sender + " -> " + notificationFailureException.Message + " -> " + notification);
}
static void ChannelException(object sender, IPushChannel channel, Exception exception)
{
//Console.WriteLine("Channel Exception: " + sender + " -> " + exception);
}
static void ServiceException(object sender, Exception exception)
{
//Console.WriteLine("Channel Exception: " + sender + " -> " + exception);
}
static void DeviceSubscriptionExpired(object sender, string expiredDeviceSubscriptionId, DateTime timestamp, INotification notification)
{
//Console.WriteLine("Device Subscription Expired: " + sender + " -> " + expiredDeviceSubscriptionId);
}
static void ChannelDestroyed(object sender)
{
//Console.WriteLine("Channel Destroyed for: " + sender);
}
static void ChannelCreated(object sender, IPushChannel pushChannel)
{
//Console.WriteLine("Channel Created for: " + sender);
}
#endregion
三.解决多信息推送,并且推送到不同的设备上.我写了一个类,来做这些事.现在也给大家看看

private readonly string appleCertPwd = ConfigurationManager.AppSettings["appleCertPwd"];//密码
private ApplePushService()
{
//确保该对象被实例化
this.push = new PushBroker();
this.messageList = new List<MessageModel>();
//关联推送状态事件
push.OnNotificationSent += NotificationSent;

这里用单例来保证,整个应用程序中只会有这一个推送对象,只有一个管道来推送.
不然的话 你多次来注册这个管道会报错的.
还遇到过 一个问题,.Newtonsoft.Json 这个程序集有时候报错,说版本不对. 这个程序集是类序列化消息的.
我的解决办法是,去获取PushSharp 的源码.官方网站：https://github.com/Redth/PushSharp
然后自己编译一下,将生成的Dll文件 拿过来 引用到你的项目中.就可以使用了 ,至于其他问题 和别的平台没有去测试
