ios - Set UILabel line spacing -

-

how can modify gap between lines in multiline uilabel?

edit: evidently nsattributedstring it, on ios 6 , later. instead of using nsstring set label's text, create nsattributedstring, set attributes on it, set .attributedtext on label. code want 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 same thing, that being deprecated.

for historical reasons, here's original answer:

short answer: can't. change spacing between lines of text, have subclass uilabel , roll own drawtextinrect, create multiple labels, or use different font (perhaps 1 edited specific line height, see phillipe's answer).

long answer: in print , online world, space between lines of text known "leading" (rhymes 'heading', , comes lead metal used decades ago). leading read-only property of uifont, deprecated in 4.0 , replaced lineheight. far know, there's no way create font specific set of parameters such lineheight; system fonts , custom font add, can't tweak them once installed.

there no spacing parameter in uilabel, either.

i'm not particularly happy uilabel's behavior is, suggest writing own subclass or using 3rd-party library. make behavior independent of font choice , reusable solution.

i wish there was more flexibility in uilabel, , i'd happy proven wrong!
