在AppDelegate
类的我的Xamarin.iOS项目中我有方法:
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
Hub = new SBNotificationHub(Constants.ListenConnectionString, Constants.NotificationHubName);
Hub.UnregisterAllAsync (deviceToken, (error) => {
if (error != null)
{
System.Diagnostics.Debug.WriteLine("Error calling Unregister: {0}", error.ToString());
return;
}
NSSet tags = null; // create tags if you want
Hub.RegisterNativeAsync(deviceToken, tags, (errorCallback) => {
if (errorCallback != null)
System.Diagnostics.Debug.WriteLine("RegisterNativeAsync error: " + errorCallback.ToString());
});
});
}
我如何从我的PCL项目中调用它?
a)在PCL项目中创建一个接口:
namespace YourNamespace.Interfaces
{
public interface IRemoteNotifications
{
void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken);
}
}
b)创建一个将在iOS项目中实现此接口的类,记住用所需属性修饰类:
[assembly: Dependency(typeof(RemoteNotifications))]
namespace YourNamespace.iOS.DependencyService
{
public class RemoteNotifications : IRemoteNotifications
{
public void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
// Place your custom logic here
}
}
}
c)使用Dependency Service从PCL项目调用您的自定义实现,以找到Interface实现。
DependencyService.Get<IRemoteNotifications>().RegisteredForRemoteNotifications(application, deviceToken);
d)执行你的逻辑。
这就是你所需要的一切。
