Trying to put user input in yahoo api URL

I am trying to learn ios and my first project is to make an app that displays weather forecast in the area the of the zip code the user enters.

I have the url which is: 

NSString *zipUrl = @"http://query.yahooapis.com/v1/public/yql?q=select%20item%20from%20weather.forecast%20where%20location%3D%2289448%22&format=json";

The zip code is near the end after 3D%22:

3D%22*89448*%22

I just need to figure out how to insert what the user entered in a text box into this spot. I have tried [NSString StringWithFormat] but there are to many % signs that it doesn't work.

Please let me know if you need any more info.

You can enter/add/put value from user input by %@ sign, such like 

NSString *urlString = [NSString stringWithFormat:@"http://query.yahooapis.com/userInput=%@",textFiled.text];

And also use stringByAddingPercentEscapesUsingEncoding for convert your URL to legal URL

NSString *urlString = [NSString stringWithFormat:@"URL_STRING"];
NSURL *myUrl = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

You need to decode zipUrl first because it encoded string.

NSString *zipUrl = @"http://query.yahooapis.com/v1/public/yql?q=select%20item%20from%20weather.forecast%20where%20location%3D%2289448%22&format=json";

    NSString *decodedString= [[NSString stringWithFormat:@"%@",zipUrl] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSLog(@"decodedString : %@",decodedString);

    NSString *myStringURL = [NSString stringWithFormat:@"http://query.yahooapis.com/v1/public/yql?q=select item from weather.forecast where location=%@&format=json",yourtextfield.text];

Hope it helps you.
