ios - Tapping on UIImageView and opening a bigger Image -


i have app displays, in tableview, image , details. i'm trying make that, when touches on image displayed in table view, app opens same image in bigger size, ability navigate between them.

this current code:

singletap = [[uitapgesturerecognizer alloc] initwithtarget:self action:@selector(imgtapped:)];  singletap.numberoftapsrequired =1; singletap.numberoftouchesrequired = 1;  -(nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section{      return [json count]; }  -(uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath{      uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:@"mycell"];      if(cell == nil){          [[nsbundle mainbundle] loadnibnamed:@"agendacell" owner:self options:nil];         cell = self.agendacell;      }      agendacell.datecell.text = [[json objectatindex:[indexpath row]] objectforkey:@"date"];     agendacell.enderecocell.text = [[json objectatindex:[indexpath row]] objectforkey:@"endereco"];     agendacell.titulocell.text = [[json objectatindex:[indexpath row]] objectforkey:@"titulo"];     [agendacell.imgcell setimagewithurl:[nsurl urlwithstring:@"http://sallescds.com.br/wp-content/uploads/2012/12/xepop-300x300.jpg"] placeholderimage:[uiimage imagenamed:@"placeholder.png"]];     [agendacell.imgcell setuserinteractionenabled:yes];     [agendacell.imgcell addgesturerecognizer:singletap];       return cell; }

here function when image tapped:

-(void)imgtapped:(uigesturerecognizer *)gesturerecognizer{      nslog(@"detectado o click no uiimageview bitch!");      imgdetailviewcontroller *imgview = [[imgdetailviewcontroller alloc] initwithnibname:@"imgdetailviewcontroller" bundle:nil];       [self.navigationcontroller pushviewcontroller:imgview animated:yes]; }

when try this, app crashes.

i don't know how you're setting agendacell, line says:

if (cell == nil) {     [[nsbundle mainbundle] loadnibnamed:@"agendacell" owner:self options:nil];     cell = self.agendacell; }

would be:

if (cell == nil) {     nsarray *nibobjects = [[nsbundle mainbundle] loadnibnamed:@"agendacell" owner:self options:nil];     cell = [nibobjects objectatindex:0]; }

see how load custom uitableviewcells xib files?
