if you're subclassing uitableviewcell can use: setselected: animated:, add configuration there.

- (void)setselected:(bool)selected animated:(bool)animated {     [super setselected:selected animated:animated];      yourimageview.transform = cgaffinetransformmakerotation(selected ? m_pi : 0);      // configure view selected state } 

if not, use inside -cellforrowatindexpath like:

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     ...     yourtablecell.yourimageview.tranform = cgaffinetransformmakerotation((selectedindex == indexpath.row) ? m_pi : 0);     ...      return tablecell; }
