Question

i am using a custom uitablecellview like i used to do .But ,unfortunately ,this time an exception is thrown when a new cell appears.So,the same portion of code have worked perfectly many times before .The only difference is that the quality of images that i put into cells is very high.
Did you have ideas?or should i explain more?
Edit
some code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *CellIdentifier = @"CellView";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    [[NSBundle mainBundle] loadNibNamed:@"SPViewControllCell" owner:self options:nil]; 
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    cell=cellView;
    self.cellView=nil;
}
UILabel *itemTitle=(UILabel*)[cell viewWithTag:1];
[itemTitle setFont:[UIFont fontWithName:@"Renaissance" size:24]];
itemTitle.text=[titles objectAtIndex:indexPath.row];

UIImageView *img=(UIImageView*)[cell viewWithTag:2];
img.image=[images objectAtIndex:indexPath.row];

return cell;

}

The exception :
“‘NSInvalidArgumentException’, reason: ‘-[UITableViewCell objectAtIndex:]: unrecognized selector sent to instance 0x5f36be0’
”
Thank you.

I’m guessing but is titles an array created with something like:

-(void) viewDidLoad(){
   // this will give you an autoreleased object
   titles = [NSArray arrayWithObjects:@"Foo",...];
   // titles will be released once the current event is handled


   // try the alloc/init style method
   titles = [[NSArray alloc] initWithObjects:... ];
   // this will create an array with the retain count still at 1, thus won't be released

Same goes for images.

What you have is the classic memory management issue where a reference you think points to say an NSArray but in fact that array is long gone and happenes to have be replaced my a some random other object.

For completness:

- (void) viewDidUnload {
    // clean up after your self 
    [titles release];
    [images release];
}
