ios - selector for multiple uibuttons in uitableviewcell -


i'm adding same selector multiple uibuttons part of uitableviewcell , works first one. missing something?

here's code:

- (void)tableview:(uitableview *)tableview willdisplaycell:(uitableviewcell *)cell forrowatindexpath:(nsindexpath *)indexpath{      nsdictionary *d = [tabledata objectatindex:indexpath.row];     nsarray *answers = [d objectforkey:@"answers"];//array of { id = 35; text = "\u03c4\u03a\u03c0\u03bf\u03c4\u03b1"; }      uilabel *startdate = (uilabel *)[cell viewwithtag:100];     long long startdateepoch = [[d objectforkey:@"startdate"] longlongvalue];     nsdate *sdate = [nsdate datewithtimeintervalsince1970:startdateepoch/1000];     nsdateformatter *startdateformatter = [[nsdateformatter alloc] init];     [startdateformatter setdateformat:@"dd/mm/yyyy"];      startdate.text = [startdateformatter stringfromdate:sdate];      ((uilabel *)[cell viewwithtag:101]).text = [d objectforkey:@"subject"];      nsarray *tags = [d objectforkey:@"tags"];     ((uilabel *)[cell viewwithtag:102]).text = [tags componentsjoinedbystring:@" "];      nsstring *imageurl = [d objectforkey:@"media"];     uiimageview *iv = (uiimageview *)[cell viewwithtag:103];     iv.contentmode = uiviewcontentmodescaleaspectfit;     [iv sd_setimagewithurl:[nsurl urlwithstring:imageurl]           placeholderimage:[uiimage imagenamed:@"placeholder.png"]];      uiview *buttonscontainer = (uiview *)[cell viewwithtag:104];     for(uiview *vv in buttonscontainer.subviews){         [vv removefromsuperview];     }     int index = 0;     nslog(@"buttonscontainer children: %d", buttonscontainer.subviews.count);     for(nsdictionary *answer in answers){         uiview *v = [[uiview alloc] initwithframe:cgrectmake(0, index * 40 + (index+1)*5, [uiscreen mainscreen].bounds.size.width, 40)];         v.backgroundcolor = [uicolor whitecolor];         cgrect labelframe = v.frame;         labelframe.origin.y = 0;         uilabel *l = [[uilabel alloc] initwithframe:labelframe];         l.text = (nsstring *)[answer objectforkey:@"text"];         l.textalignment = nstextalignmentcenter;          uiview *bottomline = [[uiview alloc] initwithframe:cgrectmake(0, v.frame.size.height - 1, v.frame.size.width, 1)];         bottomline.backgroundcolor = [uicolor colorwithred:238.0/255.0 green:205.0/255.0 blue:103.0/255.0 alpha:1.0];          uibutton *b = [[uibutton alloc] initwithframe:v.frame];          [b addtarget:self action:@selector(answered:) forcontrolevents:uicontroleventtouchupinside];          [v addsubview:l];         [v addsubview:bottomline];         [v addsubview:b];         [buttonscontainer addsubview:v];          index++;     }   } 

so example if 4 buttons added, selector called when click on first one. when click on other 3 nothing happens.

edit: adding answered: code:

- (void)answered:(uibutton *)sender {     nslog(@"@answered"); } 

ok, found it. many cudos tomswift since point gave me idea place borders on views in order debug frames size , origin.

notice give buttons same frame superviews, wrong since should not have same origin. buttons' origin should 0,0 since have same frame size superviews.

lessons learn noobs me:

  • when button not work, place borders in order make sure frame within superview's bounds.
  • do not assign same frame on view , subview. place outside of superview's bounds in 92% of cases brings undesirable behaviour.
