I would like to grab a number from a string.
The string is: "responseID: 1 is the return value";
Sometimes the number could be 1, or 3, 300, 3000…
I am trying to do this in objective C for the iphone.
I’ve tried NSPredicate and NSRegularExpression, but I can not seem to get the right regex to start with.
I tried "*[0-9]+*";
Does this return the “1” , “300” or whatever number to me when I call the regex?
Thank you!
