I'm building a twitter app for the iphone and want to detect valid internet url's and set their character count to <= 20.
I'm using NSRegularExpression to build an array of all NSRanges in the text field that start with "http". I then use NSScanner to scan until it finds whitespace or end of line characters for each range.location. I then place this new subString into a NSURL to validate that it does not return nil. I'm finding that NSURL pretty much likes everything..... http://www.cnn.thePiratesWillWinTheWorldSeries is happy. Is there a good way to validate a NSURL for the internet, short of pinging? My next step is to find the end of the substring, count back three characters and check for com,edu or org... seems clunky and inaccurate for future internet standards.
