Question

I’m somehow using stringByReplacingCharactersInRange incorrectly, but I can’t understand how. My goal is to replace one character of an NSString with another. I do this many times but after two replacements it starts cutting from the end of the NSString, I don’t want this. Here is my code.

    NSRange firstCharRange = NSMakeRange(mi, mi); // mi is an int, indicating the index of the replaced char

    myword = [myword stringByReplacingCharactersInRange:firstCharRange withString:bb.titleLabel.text]; // myword is the string

Initially, myword is @”RRRRRRRR”, after replacing the first string it becomes

eRRRRRRR

then

egRRRRRR

then

eghRRRR // why did cut off the last character?

Answer 1

The second parameter of NSMakeRange() is a length, not the end index. You probably want to just pass in 1.
