更改tableView所选单元格图像显示多个选定的单元格图像

Question

I have tableView with Cell Image i want to add selection image when any cell is selected it works fine but problem is that first you select rows one then row one is selected then you selected row2 then row2 along with row1 is selected it should be only row2 selected not both .

   - (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


 cell = [self.tableView cellForRowAtIndexPath:indexPath];

     if (indexPath.row==0) {


     cell.imageView.image=[UIImage imageNamed:@"Activity2.png"]; 
     }

     else if(indexPath.row==1){
    cell.imageView.image=[UIImage imageNamed:@"Catalog2.png"]; 


     }
   else{
    cell.imageView.image=[UIImage imageNamed:@"Library2.png"]; 

     }

    NSUInteger row = indexPath.row;
    [self.appDelegate.splitViewController viewWillDisappear:YES];

  NSMutableArray *viewControllerArray=[[NSMutableArray alloc] initWithArray: [[self.appDelegate.splitViewController.viewControllers objectAtIndex:1] viewControllers]];
  [viewControllerArray removeLastObject];
      if (row == 0) {
  self.firstDetailViewController=[[[FirstDetailViewController alloc] init]autorelease];
  [viewControllerArray addObject:self.firstDetailViewController];
  self.appDelegate.splitViewController.delegate = self.firstDetailViewController;
  }

     if (row == 1) {
self.secondDetailViewController=[[[SecondDetailViewController alloc]init]autorelease];
[viewControllerArray addObject:self.secondDetailViewController];
self.appDelegate.splitViewController.delegate = self.secondDetailViewController;

    }

   if (row == 2) {

    self.myLearningViewController=[[[MyLearningViewController alloc]init]autorelease];
[viewControllerArray addObject:self.myLearningViewController];
self.appDelegate.splitViewController.delegate = self.myLearningViewController;
    }
     }

Answer 1

If you're writing for iOS 5.0 and up, you can appeal to allowsMultipleSelection if you have this setup well. Set this to NO . Otherwise, use –deselectRowAtIndexPath:animated: say to clear the first selection. Call either of these in your implementation of -tableView:didSelectRowAtIndexPath: .

Answer 2

I think, you can set cell's background view in cellForRowAtIndexPath like this

cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.backgroundColor = [UIColor clearColor];
UIImageView *bgView= [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
bgView.backgroundColor = [UIColor clearColor];
bgView.image = [UIImage imageNamed:@"cellBgImage.png"];
cell.backgroundView = bgView;

And, in didSelectRowAtIndexPath , use this

[tableView deselectRowAtIndexPath:indexPath animated:YES];

Please check whether this helps.
