objective c - How to programmatically position and size subviews into cell's contentView -

i cell frame @ tableview:cellforrowatindexpath: in order position , size views want add uitableviewcell's contentview. there self.frame (0, 0, 320, 44).

i know can right frame in layoutsubviews (thanks this answer), if add subviews there done every time cell reused, not once in "official" example @ programmatically adding subviews cell’s content view.

in example add views using hardcoded frames like:

mainlabel = [[uilabel alloc] initwithframe:cgrectmake(0.0, 0.0, 220.0, 15.0)]; 

i guess example outdated, since should use constraints, or @ least calculate size of subviews using actual cell frame (which may impossible @ point indeed).

note: reminds me of view holder design pattern used in android.

this should return bounding frame.

cgrect cellframe = cell.bounds; 

then can use like

cellframe.size.width; cellframe.size.height; cellframe.origin.x; cellframe.origin.y; 

etc... though origin.x , origin.y should 0 each.

maybe should calculate cell height in uitableviewcell subclass , use

-(cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath 

in delegate find correct height.
