Question

In my application in tableview cell for row at index method I use the following lines of code
When my application is for analyze I got the following leak

code:

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

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    //if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    //}

    // Configure the cell...
}

I got error like this:

Value stored to cell during its initialization is never read

Answer 1

You initialize the local variable called ‘cell’ in this line:

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

and then you immediately overwrite that value in the next line:

cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

The analyzer is calling your attention to this.

In this particular case, this won’t actually result in a leak. But it does mean you are not reusing cells, and so this will affect the performance of your table view.
