Question

In my project i’ve got a Deprecations warning, initWithFrame : reuseIdentifier : is deprecated

I don’t know what it mean, could some one tell me how to resolve this warning
thanks

here is the short code

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

    static NSString *CellIdentifier = @"Cell";

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

    // Set up the cell...
    NSString *cellValue = [itemsList objectAtIndex:indexPath.row];
    cell.textLabel.text = cellValue;

    return cell;
}

and the warning is on that line :

cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];

Take a look at this Apple’s page

Here Red-Highlighted Functions and Properties will be Removed in Future by Apple in upcoming SDK.

so that we should avoid them while creating App.

Because we need longterm project which should run without crash.

a deprecated method means it has been replaced/retired but is still valid in current version of the language. it should be avoided and can cause problems/errors. check the documentation which should list an alternative method you can use.

Here you should use the method

 - initWithStyle:reuseIdentifier: 

Then your if loop would look like this

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