Either of these 2     NSString  subString    dateString subStringWithRange NSMakeRange 0 2    NSString  subString     dateString componentsSeparatedByString       objectAtIndex 0     Though keep in mind that sometimes a date string is not formatted properly and a day   or a month for that matter   is shown as 8  rather than 08 so the first one might be the worst of the 2 solutions    The latter should be put into a separate array so you can actually check for the length of the thing returned  so you do not get any exceptions thrown in the case of a corrupt or invalid date string from whatever source you have

NSArray  foo      10 04 2011  componentsSeparatedByString         NSString  firstBit    foo objectAtIndex  0     Update 7 3 2018    Now that the question has acquired a Swift tag  I should add the Swift way of doing this  It s pretty much as simple   let substrings    10 04 2011  split separator       let firstBit   substrings 0    Although note that it gives you an array of Substring  If you need to convert these back to ordinary strings  use map  let strings    10 04 2011  split separator       map  String  0    let firstBit   strings 0    or   let firstBit   String substrings 0
