Declare you implement the protocol by adding
<NSLayoutManagerDelegate> 
to your interface. Then, set:
yourTextView.layoutManager.delegate = self;
Then override this delegate method:
- (CGFloat)layoutManager:(NSLayoutManager *)layoutManager lineSpacingAfterGlyphAtIndex:(NSUInteger)glyphIndex withProposedLineFragmentRect:(CGRect)rect
{
    return 5; // Line spacing of 19 is roughly equivalent to 5 here.
}
UPDATE: 
I recently discovered that this can also be done using the NSMutableParagraphStyle setLineSpacing: API.  
In an effort to always provide useful copy-paste code-snippet awesomeness, here you go!
NSMutableParagraphStyle *myStyle = [[NSMutableParagraphStyle alloc] init];
[myStyle setLineSpacing:myLineSpacingInt];
[myString addAttribute:myDesiredAttribute value:myStyle range:myDesiredRange];
[myViewElement setAttributedText:myString];
^myViewElement can be a UITextField, UILabel, or UITextView.  
 
    
    In IOS6+ you can set the typing attributes for a UITextView
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle setLineSpacing:lineSpacing];
NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject:paragraphStyle forKey:NSParagraphStyleAttributeName];
[textView setTypingAttributes:attrsDictionary];
