Question

I am trying to use emoticons for my chat application. I am comparing the string I get or I send with a local string. If I am get the result as true I want to replace the string with an image. For that matter I am not using may emoticons.

I am trying this:

NSRange textRange;
textRange =[text rangeOfString:@":)"];

            if(textRange.location != NSNotFound)
            {

                //Does contain the substring
            }
            else
            {

           // replace string with image.
            }  

But I am not able to figure out how to replace image at the string position.

Answer 1

I assumed you want to put smileys.

So you can try this :

NSRange range = {NSNotFound, 0};
NSString *s = @"This is a smiley :) face";

range.location = 0;
range.length = [s length];
s = [s stringByReplacingOccurrencesOfString:@":)"
                                    withString:@"\ue415"
                                       options:NSCaseInsensitiveSearch
                                         range:range];
