Bug in iOS 5.0's TWTweetComposeViewController

TweetTest.m

- (void)showTweetSheet
{
    TWTweetComposeViewController *composeVC = [[TWTweetComposeViewController alloc] init];
    NSString *tweet = @"Hello, this is a message that is 117 characters long. Let's add a bunch more characters to see how long we can make i";
    
    //!!! BUG: If you switch the order of these two calls, the URL will not get added.
    BOOL urlAdded = [composeVC addURL:[NSURL URLWithString:@"http://developer.apple.com/library/ios"]];
    BOOL textAdded = [composeVC setInitialText:tweet];
    
#pragma unused(urlAdded)
#pragma unused(textAdded)
    
    [self presentModalViewController:composeVC animated:YES];
    [composeVC release];
}
