在我的xamarin.ios项目中, AppDelegate
class i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)在您的PCL项目中创建接口:
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,重新读取具有所需属性的类:
[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)使用依赖项服务从PCL项目调用您的自定义实现以找到接口实现。
DependencyService.Get<IRemoteNotifications>().RegisteredForRemoteNotifications(application, deviceToken);
d)执行您的逻辑。
这就是您所需要的。
