TextField text to float (Objective-C)

Question

How do I convert the text inside of a TextField to a float in Objective-C?

Answer 1

float myFloat = [[myTextField text] floatValue];

Edit: technically the most proper way to do this would be to use an NSNumberFormatter, since that will return a nil NSNumber if it can't parse the string properly, whereas floatValue will just return 0.0 for a malformed string. But floatValue is usually adequate for most purposes.

Answer 2

If it's an NSTextField you call floatValue on the actual object, not on what's returned from text. NSTextField does not have a text method.

float myFloat = [myTextField floatValue];
