How do you pass in a String variable value to another string

Question

Basically I did this and I got an error:

NSString *searchWord = @"Lilwayne";

NSString *resourceURL = (@"https://api.soundcloud.com/tracks?client_id=546952635e22cc0182d85daceff34381&q=%@&format=json", searchWord);

Error is:

reason: 'Resource 'Lilwayne' is invalid because the scheme is not 'https'.'

I don't understand why this doesn't work. However if I remove the "%@" and replace it with "Lilwayne" it works.

The reason why I am doing it this way is because I have a search feature in my app to search for songs using the soundcloud sdk and I want to dynamically change the value of the variable "searchword" to whatever the user typed in.

Answer 1

Try to use stringWithFormat

NSString *resourceURL = [NSString stringWithFormat:@"https://api.soundcloud.com/tracks?client_id=546952635e22cc0182d85daceff34381&q=%@&format=json", searchWord];

Answer 2

I suggest a trip to the NSString class reference in the Xcode help system. In addition to stringWithFormat, as suggested by Basheer, There is a section on combining strings.
