Question

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

Answer 1

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];
