Replace Emoticons

问题

Is it possible to replace a word with emoticons?

For example

NSString *myString = @"I am sad of him"

now i want to check the word whether it contains the word "sad", if it has i want to replace that word with sad emoticons.

I am not sure how to have emoticons in the nsstring

Please let me know

回答1:

yeah, you can do this using this:

myString = [NSString stringByReplacingOccurrencesOfString:@"sad" withString:@"\ue058"];

Check this link for emoji codes: (replace the &#x with \u though) http://barrow.io/posts/iphone-emoji/

回答2:

you can use NSAttributed String to show emotion icon but before that you have to search "sad" word in whole paragraph by using normal search method. :)
