Adding a title to a location when linking to the Maps App

[Rojam Nairassoy]

Hello everyone, I am linking to a specific location from my app to the Maps app, and I would like to give said location a custom title. I am very close to getting this working, but something wonky is happening whenever there is a space in the title and I can't figure out the correct code to get it working. Here is what I have:

NSString *mapURL = [[[NSString alloc] initWithFormat: @"http://maps.google.com/maps?f=q&source=s_q&hl=en&q=%@,+%@+(Custom%20Title%20Here)", videoLat, videoLon] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString: mapURL]];

Everything is working correctly, the latitude and longitude variables and being pulled in, I just don't know the correct formatting to get the title working. The above example is pretty close, the title would be something like Custom2itle2ere. I also tried using %A0 for the spaces in the title, but this produced a bunch of garbled text. Anyhow, any help would be greatly appreciated, thanks!

Bump.

Just a shot in the dark here:

Instead of stringByAddingPercentEscapesUsingEncoding: on the entire url, do it only for the title part.

Also, there's no need to use [[NSString alloc] ...] in your case. You can just use [NSString stringWithFormat:];

Try this:

NSString *mapURL = [NSString stringWithFormat:@"http://maps.google.com/maps?f=q&source=s_q&hl=en&q=%@,+%@+%@",
     videoLat, videoLon, [[NSString stringWithString: @"(Custom Title Here)"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString: mapURL]];
