Remove last character of NSString

Question

I've got some trouble 'ere trying to remove the last character of an NSString. I'm kinda newbie in Objective-C and I have no idea how to make this work.

Could you guys light me up?

Answer 1

NSString *newString = [oldString substringToIndex:[oldString length]-1]; 

Always refer to the documentation:

• substringToIndex:
• length

---

To include code relevant to your case:

NSString *str = textField.text; NSString *truncatedString = [str substringToIndex:[str length]-1]; 

Answer 2

Try this:

s = [s substringToIndex:[s length] - 1];
