Question

I have an NSString

NSString *data = @"abcdefghi";

but I want the data to be the "defghi"

What can I do to change it?

Answer 1

You could do :

NSMutableString *data = [NSMutableString stringWithString:@"abcdefghi"];
[data deleteCharactersInRange:NSMakeRange(0, 3)];

This is using NSMutableString which allows you to delete and add Characters/Strings to itself.

The method used here is deleteCharactersInRange this deletes the letters in the NSRange, in this case the range has a location of 0, so that it starts at the start, and a length of 3, so it deletes 3 letters in.
