This one is funky... I have a controller and a view. The view contains a single textfield and several NSStrings. The view will have the user enter the info and will store it in the NSStrings. The view controller will then create a NSDictionary and send that to the delegate. Anyway, all of that works fine and just to plan unless you use a space in the text field and in that case it crashes the app. I tried something like this in the textFieldDidEndEditing: Code: myFirstNSStringValue = [[textField text] stringByReplacingOccurrencesOfString:@" " withString:@""]; As well as striping the white spaces just as a temporary fix until I can get past the spaces problem overall. But neither worked. Any ideas?
