Question

I forgot to put session command when I built first version of an iPhone application. Now, I wrote a session check command in every PHP function.

However, the first version is not working well because it loses session sometimes. A lot of people are using the first version already and can’t change it at this moment.

So, I was thinking that if I can get udid value of iPhone by using php command, I get give them a new session value who lose session data. or is there other solution to make this happen?

Thank you.

You can send udid from iphone using webservice to php and then you can access it.

 NSString *token=[NSString stringWithFormat:@"%@",deviceToken];
token= [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
token= [token stringByReplacingOccurrencesOfString:@">" withString:@""];
token= [token stringByReplacingOccurrencesOfString:@" " withString:@""];
NSString *post = [NSString stringWithFormat:@"token=%@",token];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.server.com/web-service/save-token.php?"]]];
 [request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];

[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"];
[request setHTTPBody:postData];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnstring = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
