Hiding a UINavigationController's UIToolbar during viewWillDisappear:

Question

I\'ve got an iPhone application with a UITableView menu. When a row in the table is selected, the appropriate view controller is pushed onto the application\'s

Answer 1

I am in agreement with Jeff's answer. But there is a UI glitch if I hide the toolbar in -viewDidAppear method of the viewController through which different viewControllers are pushed.

To avoid this, I was experimenting and found out that calling -setToolbarHidden in the -viewWillAppear call indeed hides the toolbar, but as the question states, the view though expanded would not be occupied by the tableview rows.

To fix this, I have changed to following code and now it works without the glitch:

- (void)viewDidLoad
{
    [super viewDidLoad];
.
.
.
    [self reframeRowHeight];
    [self.menuItemTableView addObserver:self
                             forKeyPath:@"frame"
                                options:NSKeyValueObservingOptionNew
                                context:nil];
    [self.menuItemTableView setBounces:NO];
.
.
.
}
-(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
    if ([keyPath isEqualToString:@"frame"])
    {
        [self reframeRowHeight];
    }
}

-(void)reframeRowHeight
{

    [self.menuItemTableView setRowHeight:self.menuItemTableView.frame.size.height/self.menuItems.count];
    [self.menuItemTableView reloadData];
}

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
.

    [self.navigationController setToolbarHidden:YES animated:YES];

}
