Regular expression for numbers

I need a regular expression to detect 开发者_StackOverflowat least one number in a string. Other characters can be anything. Please help me to implement this in objective C.

\d+

Match one or more digit.

This is a very similar question to:

Regular Expressions in Objective-C and Core Data

Check ICU Regex Documentation for figuring out your regular expression needs

To match a digit anywhere in string use .*\\d.*. To implement in objective-c use NSPredicate try something like this:

NSString *matchphrase = @".*\\d.*";
  BOOL match = NO;
  NSString *item = @"string with d1g1it";
  NSPredicate *matchPred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", matchphrase];
  match = [matchPred evaluateWithObject:item];
