UIApplication sharedapplication openURL not working

In my case problem was in extra "/" at the end.

doesn't work:
@"http://www.facebook.com/asbreckenridge/"

works fine:
@"http://www.facebook.com/asbreckenridge"

Try it without the encoding like this.

- (IBAction)facebookButtonPress:(id)sender {
    NSLog(@"fb hit");
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"www.facebook.com/asbreckenridge"]];
}

Also try changing the URL to http://www.facebook.com/asbreckenridge

Try this:

- (IBAction)facebookButtonPress:(id)sender {
NSLog(@"fb hit");
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.facebook.com/asbreckenridge"]];
}
