如何检测iPhone或iPad的用户代理？

Question

I am using the following code to parse a remote XML :

NSString *urldata=[[NSString alloc]initWithFormat:@"http://url.com/test/a.php"];
NSString *encode=[urldata stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(@" urldata %@",urldata);
TBXML *tbxml =[TBXML tbxmlWithURL:[NSURL URLWithString:encode]];

And my php script has $useragent= $_SERVER['HTTP_USER_AGENT'] ; . I am unable to determine the user agent. However if call the url from safari ipad or iphone I have the user agent correctly.

You need to use an NSMutableURLRequest in your iPhone code where you can set the user agent. Because it's not being sent to your php webserver as it is not mandatory to send
