ios - Size Class Customization in UITableViewCell -

i have height constraint in uiimageview contained in uitableviewcell, , want 180 iphone , 300 ipad.

but doesn't make effect ipad.

it table view automatic dimension.

- (void)configuretableview {     self.tableview.allowsselection = no;     self.tableview.estimatedrowheight = 30.f;     self.tableview.rowheight = uitableviewautomaticdimension; } 

how can customize cell's height ipad?

update: fixed implementing delegate method:

- (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {     cgfloat height = -1;     if (indexpath.section == kquizcontrollersection_description && indexpath.row == kdescriptionquizcell_previewimage) {         if (ui_user_interface_idiom() == uiuserinterfaceidiompad) {             height = 400;         }         else {             height = 180;         }     }     return height; } 

because other cells resized dynamically (cells multiline labels) method returns negative number every other cell. correct approach?

i there uiimageview same height cell ....then pinned edges of uiimageview , there not need of height constraint of uiimageview...

you need set height of cell according device in heightforrowatindexpath method

func tableview(tableview: uitableview, heightforrowatindexpath indexpath: nsindexpath) -> cgfloat {      if uidevice.currentdevice().userinterfaceidiom == .pad{         return 300     }     else{         return 180     } }   

the other scenario uiimageview not same height cell....then make 1 iboutlet of height constraint of uiimageview , change constant per requirement...

    if uidevice.currentdevice().userinterfaceidiom == .pad{         heightconstraint.constant = 300     }     else{         heightconstraint.constant = 180     }
