Featured iPhone Development Resources,iOS Development Libraries,Objective-C,Open Source iOS Libraries And ToolsI’ve mentioned regular expressions a few times, most recently with this free tool for building regular expressions easily that works great for the creation of valid regular expressions to use with NSRegularExpression.
Here’s a handy library called VRXVerbalExpressions that allows you to create regular expression style queries with a verbal syntax.
VRXVerbalExpressions is an Objective-C port of the Verbal Expressions library, and here’s an example from the tests in the source code showing how one could check for a valid url:
[r startOfLine];
[r then:@"http"];
[r maybe:@"s"];
[r then:@"://"];
[r maybe:@"www."];
[r anythingBut:@" "];
[r endOfLine];
}];
You can find VRXVerbalExpressions on Github here.
Perfect for those of us who don’t use regular expressions all the time.
