my app is about learning the Swedish language. the use taps on PLAY button. A voice will say a word. e.g: "Sweden is great".(but in swedish) The user writes what he heard. But when is come to comparing the users answer and the source text, Im in a big trouble. Code: source text= @"Sweden is great"; inputText=@"Sweden iz great"; int correctWords = 0; how can I compare so that the user gets 1 point for each correct word? I found some help here but I dont get a single line. search for NSString Class Reference in Xcode documentation. Thank you very much. Please help me!
