일부 컨트롤을 보여주는 tableView가 있습니다. UIButton.i에서 올바른 ans에 대한 옵션과 마찬가지로 올바른 배경으로 버튼 배경 이미지를 변경하고 click 이벤트에서 잘못된 ans를 변경할 수 있습니다. 어떤 사람이 내게 아이디어를 줄 수 있습니까? 내가 같은 배경 이미지 변경하려고 :UIButton 배경 이미지 클릭 변경시
[cell.ansBtn2 setImage:[UIImage imageNamed:@"option_red.png"] forState:UIControlStateSelected];
과 내가 같은 backgound에 설정 한 :
-(void) btnAction:(id) sender {

NSLog(@"%@",str);
NSLog(@"%@",[dictionary objectForKey:@"option3"]);
correctAns=[dictionary objectForKey:@"answer"];
if(str==[dictionary objectForKey:@"option1"])
{
[email protected]"1";
if ([selectedAns compare:correctAns]==NSOrderedSame)
{
[cell.ansBtn1 setBackgroundImage:[UIImage imageNamed:@"option_green.png"] forState:UIControlStateHighlighted];
NSLog(@"this is correct");
countCorrect++;
cell.lblRating.text=[NSString stringWithFormat:@"%i", countCorrect];
}
else
{
