you need this

-(void)selectuser:(id)sender {     uibutton *button=(uibutton *) sender;     nsindexpath *indexpath = [nsindexpath indexpathforrow:button.tag insection:0];     customtableviewcell *tappedcell = (customtableviewcell *)[yourtableview cellforrowatindexpath:indexpath];     if ([tappedcell.selectbutton.imageview.image isequal:[uiimage imagenamed:@"green.png"]])     {         [tappedcell.selectbutton setimage:[uiimage imagenamed:@"grey.png"] forstate:uicontrolstatenormal];     }     else     {         [tappedcell.selectbutton setimage:[uiimage imagenamed:@"green.png"] forstate:uicontrolstatenormal];     } }

in cellforrowatindexpath method, set cell's indexpath button tag

cell.selectbutton.tag=indexpath.row;

and set selector button 

[cell.selectbutton addtarget:self action:@selector(selectuser:) forcontrolevents:uicontroleventtouchupinside];

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
