Question

I have a string in iphone that looks like the following one:

    my.whatever.string.with.unknown.length=something whatever something = something .... = whatever

I want to replace only the FIRST “=” with something else.

If I use :

    [myString stringByReplacingOccurrencesOfString:@"=" withString:@"somethingHere" ]; 

It will replace all occurences of “=” . Any suggestions on how to achieve this?
