example: word with number in string
NSString *str = [NSString stringWithFormat:@”this is an 101 example1 string”]
Since example1 has a number in the end and i want to remove it. I can break it into an array and filter it out using predicate, but that seems slow to me since I need to do like a million of these.
What would be a more efficient way?
Thanks!
Probably NSRegularExpression. I think
([^0-9 ]+)\d+|\d+([^0-9 ]+)should do it. Just replace it with$1.
