UITableView reloadData crash - iphone

Question

I added CustomImageView to the UITableViewCell.
UITableViewCell *cell = nil;
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell1"] autorelease];
}
CustomImageView *customIV = [[CustomImageView alloc] init];
[cell.contentView addSubView:customIV];
[customIV release];
But when I try to reload tableview, the error occurs.
error call stack is same as follows.
Output string is as follows.
-[CustomImageView superview]: message sent to deallocated instance 0x1f848f30

Answer 1

CustomImageView *customIV = [[CustomImageView alloc] initWithFrame:CGRectMake(x, y, w, h)];
[cell.contentView addSubView:customIV];
It's done with me when I've released memory.
So according to me, No need to release, because it'll deallocated memory.
Hopefully, it'll help you.Thanks.

Answer 2

Try to Comment this line[customIV release]; & run , it should not crash while reloading data.
The reason behind this is everytime it tries to create new custom view & releases it, so causes extra load on system & crash occurs.

You only want to add the image once to each cell. Change your code to this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell1"];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell1"] autorelease];
CustomImageView *customIV = [[CustomImageView alloc] init];
[cell.contentView addSubView:customIV];
[customIV release];
}
return cell;
}
If this doesn't work then you need to show your complete cellForRowAtIndexPath method. By only showing part of your code you make it difficult to help.

Answer 4

This error occur because each time CustomImageView object created when your cell created.
so, best way is first initialize object of CustomImageView then create your UITableView
such like,
CustomImageView *customIV put it in your .h file and then #synthesize it in .m File
(put this code above UITableView)
self.customIV = [[CustomImageView alloc] init];
Then create UITableView
self.tablView = [[UITableView alloc]init];
.
.
.
.
And in cellForRowAtIndexPath only add [cell.contentView addSubView:self.customIV];
