Adjust height UITableViewCell in viewDidLoad to content

Question

I have a UITableView called Facebook that contents two buttons, sometimes only is necesary show one button, but I have a problem because there are a empty space and this is not pretty in my app. I want resize this view but, nothing happens, only the FacebookButtonLogin is hidden, but the view is not resized.

-(void) viewDidLoad
{     
        self.FacebookButtonLogin.hidden = YES;
        CGRect newSize = self.Facebook.frame;
        newSize.origin.x = 0;
        newSize.origin.y = 0;
        newSize.size.width = self.cellFacebook.frame.size.width;
        newSize.size.height = UI_USER_INTERFACE_IDIOM() ? 48 : 48;
        //[[self Facebook]setFrame:newSize];
        self.Facebook.frame = newSize;
}

Thanks in advance!

The height a particular row is controlled by the method tableView:heightForRowAtIndexPath: of you UITableViewDelegate. You cannot manually change the size of a cell, it is resized by the TableView to the cell size (tableView width and row height) when it layouts its subviews.

On another point, what it the point of this line:

newSize.size.height = UI_USER_INTERFACE_IDIOM() ? 48 : 48;

It sets the same value and compares the idiom to 0 instead of iPhone or iPad (one of them might have the value 0, so the check might be working for now, but using the constants is better).

"You cannot manually change the size of a cell, it is resized by the TableView to the cell size". I didn't know that! Thanks! I waste time trying of make that :) !! — lightless07, Jul 05 '13 at 18:53
