iOS 7 contact number spaces are not spaces [duplicate]

Answer 1

Try this:

NSString *cleaned = [[phoneNr componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] componentsJoinedByString:@""];

This should work for any kind of space (of which there are many). It may seem somewhat inefficient, but for phone numbers, this should be ok.

Answer 2

Another (very flexible) option is to use a regular expression. This allows you to retain the + or any other characters you want to remain.

let numberFromAddressBook = "+1 818 323 323 323"

let cleanNumber = numberFromAddressBook.stringByReplacingOccurrencesOfString("[^0-9+]", withString: "", options: NSStringCompareOptions.RegularExpressionSearch, range:nil)

"+1818323323323"
