Question

On iOS 5, I’m trying to open a native twitter app with a dynamic hashtag search term.

I’ve tried:

- (void)openForHashTag:(NSString *)hashTag {
UIApplication *app = [UIApplication sharedApplication];

NSURL *twitterURL = [NSURL URLWithString:[NSString stringWithFormat:@"twitter://search?q=%@", hashTag]];
DLog(@"Hashtag URL: %@ ", twitterURL);

if ([app canOpenURL:twitterURL]) {
    [app openURL:twitterURL];
}
else {
    NSURL *safariURL = [NSURL URLWithString:[NSString stringWithFormat:@"http://mobile.twitter.com/search?q=%@", hashTag]];
    [app openURL:safariURL];
}

}

It seems to go to the hashtag search page, but spends forever loading… Is twitter://search?q=%@ the wrong format?

Answer 1

Well, after a lot of head scratching, I realised that the search query for a hash tag should not contain an actual hash tag… Therefore by adding the line

 NSString *cleanString = [hashTag stringByReplacingOccurrencesOfString:@"#" withString:@""];

it now works fine… Mystery solved.
