Question

I’m developing an iOS app dealing with push notifications. Our push notification server is written in ColdFusion and is using com.notnoop.apns.SimpleApnsNotification to send the notifications. In the app, I grab the device token (NSData) and Base64 encode it before sending it off to the server. However, while the SimpleApnsNotification api is expecting a String for the token, it doesn’t appear to want a Base64 encoded String.

Do you know what encoding SimpleApnsNotification is expecting for the device token?

Answer 1

You’ve got to hex encode it. Try making a Category on NSData with this method in it (this worked great for me):

 - (NSString*) hexEncode {
NSString *deviceToken = [[self description] stringByReplacingOccurrencesOfString: @"<" withString: @""];
deviceToken = [deviceToken stringByReplacingOccurrencesOfString: @">" withString: @""] ;
deviceToken = [deviceToken stringByReplacingOccurrencesOfString: @" " withString: @""];
return deviceToken;
}

Give that a try and see if it works for you, too.
