set UITableView image

I am trying to load locally stored images in a background thread and set them as UITableViewCell images. I keep getting an exception and don't really know how to approach it.

Here is my code:

- (void)loadImageInBackground:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

NSString *path = [[tableImages objectAtIndex:indexPat开发者_C百科h.section]objectAtIndex:indexPath.row];

UIImage *img = [[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:path ofType:@"png"]];

[self performSelectorOnMainThread:@selector(assignImageToImageView:) withObject:img waitUntilDone:YES];

[img release];  
[pool release];
}

- (void) assignImageToImageView:(UIImage *)img
{

UITableViewCell *cell = (UITableViewCell *)[self.tableView viewWithTag:0];

((UIImageView *)cell.imageView).image = img;
}

Anyone have any ideas? Thanks to all!

As is mention in your error you are trying to set image to object of class UITableView. It is impossible.

In your code it is error here:

UITableViewCell *cell = (UITableViewCell *)[self.tableView viewWithTag:0];

By default all views has default view tag set to 0. When your are calling that method to your tableView it returns you first UIView with tag == 0. I think you didn't change default tag of your UITableView *tableView so that method returns you tableView and not UITableViewCell.

In this case, you need to choose right way to access appropriate UITableViewCell *cell;.
