passing UDID to url

I am having trouble passing the UDID to a url in xcode:

[web loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://example.com/?udid="+[UIDevice currentDevice].uniqueIdentifier]]];

The above does not work. How can I fixed that?

You'll need to construct your URL string properly... "+" doesn't concatenate strings in Objective-C. Use a method like -stringWithFormat: instead.

The concatenation is diferent in Objective C.

DO THIS:

NSString *udid = [UIDevice currentDevice].uniqueIdentifier;
NSString *string = [NSString stringWithFormat:@"http://example.com/?udid=%@",udid];
NSURL *url = [NSURL URLWithString:string];
[web loadRequest:[NSURLRequest requestWithURL:url]];

You cannot do string concatenation with a "+" in Objective-C. It should be

[NSURL URLWithString: [@"http://www.example.com/?udid=" stringByAppendingString: [UIDevice currentDevice].uniqueIdentifier]]
