deviceToken of IOS Device

Question

I am using Monotouch for mac and have gone through the steps to retrieve a provisioning profile certificate enabling push notification in the process. I have a working app and am now experimenting with apns-sharp and moon-apns but cant' figure out how to retrieve my device token. I'm hoping someone can provide me with detailed and straightforward steps to achieve this.

Answer 1

In your FinishedLaunching method, register the app for remote notifications, through the UIApplication object you get in it:

// Pass the UIRemoteNotificationType combinations you want
app.RegisterForRemoteNotificationTypes(UIRemoteNotificationType.Alert |
 UIRemoteNotificationType.Sound);

Then, in your AppDelegate class, override the RegisteredForRemoteNotifications method:

public override void RegisteredForRemoteNotifications (UIApplication application, NSData deviceToken)
{
    // The device token
    byte[] token = deviceToken.ToArray();
}

You also have to override the FailedToRegisterForRemoteNotifications method, to handle the error, if any:

public override void FailedToRegisterForRemoteNotifications (UIApplication application, NSError error)
{
    // Do something with the error
}

As of iOS deviceToken has changed. The following code worked for me to convert deviceToken as NSData to a string.

string deviceTokenString;
if (UIDevice.CurrentDevice.CheckSystemVersion(13, 0))
{
    deviceTokenString = BitConverter.ToString(deviceToken.ToArray()).Replace("-", string.Empty);
}
else
{
    deviceTokenString = Regex.Replace(deviceToken.ToString(), "[^0-9a-zA-Z]+", string.Empty);
}
