Question

I’m working on an iOS app that requires the user to enter numbers into a UITextField using the keyboard type UIKeyboardTypeDecimalPad. However I just realized that there is no support for entering negative numbers, which is a requirement of the application.

Any ideas or thoughts on how I can accomplish this?

This clearly isn’t my best answer.. but i’m unable to delete it since it is accepted.

may this code will help you:

if you want a negative number just use “-”

NSString *fieldString = [NSString stringWithFormat:@"%@",Textfield.text];

        NSLog(@"%@",fString);

        int fieldValue;
        value = [fString intValue];
        NSLog(@"%d",fieldValue);

this will work for decimal numbers

            double fieldValue;
            value = [fString doubleValue];
            NSLog(@"%f",fieldValue);
