iOS Extract Integer from UITextField?

[parkov]

Newbie question here.

How do I extract an int value from a UITextField (textKey)? I have the following:

NSInteger inputKey = textKey.text;​

Which gives me this warning:

warning: initialization makes integer from pointer without a cast​

Thanks!

You can't take an object and assign it to a primitive. NSInteger is really just a typedef of int. You can do this:

NSInteger theInteger = [textKey.text intValue];

Thanks. Can you go in the other direction, or do you have to use methods for those as well? For example:

creating an NSMutableArray from ints

creating an NSString from chars
