Iphone device token - NSData or NSString

Question

Hi Guys,

I am receiving iPhone device token in the form of NSData object. When I tested my notifications script function, I have only copied that object from log and the notifications went fine. However when I try now to automatically do it, I am sending the device token as ASCII encoded string in the form of variable

self.deviceToken = [[NSString alloc] initWithData:webDeviceToken encoding:NSASCIIStringEncoding];

The string that I am getting has some funky characters and looks similar to this "å-0¾fZÿ÷ʺΎU…Q‘üR—áqEªfÔk«"

When server side script sends the notification to that token, I am not receiving anything.

Do I need to decode something and how?

Ok, I found a solution. If anyone has the same problem, forget about ASCII encoding, just make the string with the following lines:

NSString *deviceToken = [[webDeviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
deviceToken = [deviceToken stringByReplacingOccurrencesOfString:@" " withString:@""];

I don't think it's a good solution, as you have to reconstruct the string before sending the notifications to Apple servers. Use Base64 encoding for transmitting the strings or something similar.
