ios - Auto-resize label + UitableView. Doesn't resize -

-

i have table cell 3 labels. 2 of them has "lines: 0".

cell view

i set hugging , resistance priority http://www.raywenderlich.com/73602/dynamic-table-view-cell-height-auto-layout

and works fine, if tableview located in "tabbarcontroller". if put same tableview simple viewcontroller, label1 not expanding.

fine: fine

wrong: wrong

i use 1 cell class , cell xib both of tables. , 1 class tables delegate/data source.

tables delegate:

   func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {        var cell = table.dequeuereusablecellwithidentifier("gravetableviewcell") as? gravetableviewcell        if (cell == nil) {            cell = nsbundle.mainbundle().loadnibnamed("gravetableviewcell", owner: self, options: nil)[0] as? gravetableviewcell            cell?.configurecell(data[indexpath.row])        }        return cell!     }

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
