ios - UITextView lineHeightMultiple Clips Top, first line, of Text -


in ios 8, have vanilla uitextview clips top of 1st line when lineheightmultiple applied it's nsmutableparagraphstyle, see image below:

text clipping

it appears though lineheightmultiple affects 1st line of text in addition subsequent lines.

setting clipstobounds = false on uitextview @ least enable clipped part show, can see image below top part of text above it's frame:

text above frame

i can fix setting top constraint on offending uitextview compensate clipstobounds = false feels hack me.

i have tried using wkwebview offending text, , setting css line-height property, , works fine. there must missing when comes uitextview though.

additionally, setting linespacing on paragraph style less 0 has no affect, per docs:

the distance in points between bottom of 1 line fragment  , top of next.  **this value nonnegative.**  value included in line fragment heights in  layout manager.

i have tried setting contentinset of uitextview using system font, both had not affect.

my sample code setup follows:

let text = "this multiline run of text"  let font = uifont(name: "myfontname", size: 31.0)! // let font = uifont.systemfontofsize(31.0)  let paragraph = nsmutableparagraphstyle() paragraph.lineheightmultiple = 0.75 paragraph.alignment = nstextalignment.center  let attributes = [     nsparagraphstyleattributename: paragraph,               nsfontattributename: font ]  titleview.attributedtext = nsattributedstring(string: text, attributes: attributes)  // titleview.contentinset = uiedgeinsets(top: 50.0, left: 0.0, bottom: 0.0, right: 0.0) titleview.clipstobounds = false

has encountered , overcome or top constraint hack way go?

i had same issue.

i compensated using nsbaselineoffsetattributename.

you should use:

let attributes = [     nsparagraphstyleattributename: paragraph,     nsfontattributename: font,     nsbaselineoffsetattributename: -5 ]

you have set lower paragraph.lineheightmultiple.

a little tricky, works.
