reloadData in a UITableView when deviceOrientation change

Question

I'm working with a UITableView, with UITableViewCell. My appsupports the landscape orientation so i've created 2 UITableViewCell: one for the portraid and one for the landscape.

In my cellForRowAtIndexPath method this is my code

static NSString *CellIdentifier;
static NSString *NibNamed;

UIDeviceOrientation deviceOrientation = [UIApplication sharedApplication].statusBarOrientation;

if (deviceOrientation != UIDeviceOrientationLandscapeLeft &&
    deviceOrientation != UIDeviceOrientationLandscapeRight)
{
    CellIdentifier= @"Cell1";
    NibNamed = @"cell_news";
}
else
{
    CellIdentifier= @"Cell2";
    NibNamed = @"cell_news_landscape";
}

[[NSBundle mainBundle] loadNibNamed:NibNamed owner:self options:NULL];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];


if (cell == nil)
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:NibNamed owner:self options:nil];
    cell = [nib objectAtIndex:0];
}
///here i add title, description, ecc... in my UITableViewCell

Then in shouldAutorotateToInterfaceOrientation i wrote this:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
[my_table reloadData];
return YES;
}

Where is the problem? If i start the app in portrait, when i rotate the device the first time, nothing happen (and the UITableCellView is the portrait_table_cell). When i rotate the device for the second time (and i'm in portrait or in upsideDown), i see the landscape_table_cell (and, of course, i don't see all the text because it goes out from the screen). So.. except the firt time, the other times that i rotate the device, i see the wrong table_cell_view!!

Do you know why? Thanks!

Answer 1

Your data is reload before the device changed orientation. shouldAutorotateToInterfaceOrientation is called before any rotation.

Try the didRotateFromInterfaceOrientation

- (void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
 [my_table reloadData];
}

Also note the answer given by Jhaliya, because that solution will be better then reloading you tableview. You should only reload the tableview if the datasource has changed.

Answer 2

Not call reloadData from shouldAutorotateToInterfaceOrientation:

Use the UIView autoresizingMask property for both UITableView and UITableViewCell when you create the object for both . because UITableView andUITableViewCellare the subclass ofUIView`.

@property(nonatomic) UIViewAutoresizing autoresizingMask
