Edit  Evidently NSAttributedString will do it  on iOS 6 and later  Instead of using an NSString to set the label s text  create an NSAttributedString  set attributes on it  then set it as the  attributedText on the label  The code you want will be something like this   NSMutableAttributedString  attrString     NSMutableAttributedString  alloc  initWithString   Sample text    NSMutableParagraphStyle  style     NSMutableParagraphStyle alloc  init    style setLineSpacing 24    attrString addAttribute NSParagraphStyleAttributeName     value style     range NSMakeRange 0  strLength    uiLabel attributedText   attrString    NSAttributedString s old attributedStringWithString did the same thing  but now that is being deprecated   For historical reasons  here s my original answer   Short answer  you can t  To change the spacing between lines of text  you will have to subclass UILabel and roll your own drawTextInRect  create multiple labels  or use a different font  perhaps one edited for a specific line height  see Phillipe s answer    Long answer  In the print and online world  the space between lines of text is known as  leading   rhymes with  heading   and comes from the lead metal used decades ago   Leading is a read-only property of UIFont  which was deprecated in 4 0 and replaced by lineHeight  As far as I know  there s no way to create a font with a specific set of parameters such as lineHeight  you get the system fonts and any custom font you add  but can t tweak them once installed   There is no spacing parameter in UILabel  either   I m not particularly happy with UILabel s behavior as is  so I suggest writing your own subclass or using a 3rd-party library  That will make the behavior independent of your font choice and be the most reusable solution   I wish there was more flexibility in UILabel  and I d be happy to be proven wrong

Best thing I found is  https   github com mattt TTTAttributedLabel  It s a UILabel subclass so you can just drop it in  and then to change the line height   myLabel lineHeightMultiple   0 85  myLabel leading   2

Of course  Mike s answer doesn t work if you pass the string programmatically  In this case you need to pass a attributed string and change it s style   NSMutableAttributedString   attrString     NSMutableAttributedString alloc  initWithString   Your  nregular  nstring    NSMutableParagraphStyle  style     NSMutableParagraphStyle alloc  init    style setLineSpacing 4    attrString addAttribute NSParagraphStyleAttributeName                    value style                    range NSMakeRange 0  attrString length     label attributedText   attrString
