ios - Size UITextView to contents in Swift -

-

i have seen , tried few solutions online size text view contents nothing seems working. have auto layout on, scrolling disabled, , here code in viewdidload i'm using try , resize text view dynamically.

var frame = abouttext.frame     frame.size.height = abouttext.contentsize.height     abouttext.frame = frame

i have tried 

abouttext.sizetoft() abouttext.layoutifneeded()

edit: tried:

let fixedwidth = abouttext.frame.size.width     abouttext.sizethatfits(cgsize(width: fixedwidth, height: cgfloat.max))     let newsize = abouttext.sizethatfits(cgsize(width: fixedwidth, height: cgfloat.max))     var newframe = abouttext.frame     newframe.size = cgsize(width: max(newsize.width, fixedwidth), height: newsize.height)     abouttext.frame = newframe

technically, because using auto layout, should able use constraints , compression/stretching priorities set text view size contents. text view's natural behavior.

however, if should fail, here code should force size content:

let size = textview.sizethatfits(cgsizemake(width,  cgfloat(flt_max))) // width width text view should be, width of parent view - 20 textview.frame = cgrectmake(textview.frame.origin.x, textview.frame.origin.y, size.width, size.height) // may have call view.layoutifneeded()

update ** auto textview sizing uitableview

implement in uitableviewdelegate:

override func tableview(tableview: uitableview, estimatedheightforrowatindexpath indexpath: nsindexpath) -> cgfloat {     return uitableviewautomaticdimension }

then constrain text view top , bottom of table view cell. each table view cell should resize fit it's content text.

this video should address problem exactly, helped me lot: https://developer.apple.com/videos/wwdc/2015/?id=231
