<div style="font-family: Menlo; font-size: 11px; margin: 0px;">You can replace the string that you need to search with any string and it will return the number of replaces (the number of ocurrences of the string):

</div><pre style="background-image: URL(http://2.bp.blogspot.com/_z5ltvMQPaa8/SjJXr_U2YBI/AAAAAAAAAAM/46OqEP32CJ8/s320/codebg.gif); background: #f0f0f0; border: 1px dashed #CCCCCC; color: black; font-family: arial; font-size: 12px; height: auto; line-height: 20px; overflow: auto; padding: 0px; text-align: left; width: 99%;"> int count = [baseString replaceOccurrencesOfString:@"stringToFind" withString:@"anyString" options:NSLiteralSearch range:NSMakeRange(0, [baseString length])];
</pre>
NOTE: Be careful, this will change the string in the baseString, so copy the string if you need to use it later.
