How to hide master view in UiSplitviewcontroller in ipad

Question

Is there is any way to hide the master view in a splitviewcontroller programmatically. In my application the first screen will be of a splitviewcontroller, i don\'t need any

This works:

Attach the "hide" method to your button, for example:

UIBarButtonItem *hideButton = [[UIBarButtonItem alloc] initWithTitle:@"hide"
                                         style: UIBarButtonItemStylePlain
                                        target: self
                                        action: @selector(hide:)
                              ];

[self.mainView.navigationItem setLeftBarButtonItem:hideButton];

In this code, the "self.mainView" is the view controller in the navigation controller in the second view of the splitview - just as a reference.

The hide method looks like so.

-(void)hide:(id)sender
{
    UIViewController *masterController = [self.viewControllers objectAtIndex:0];

    CGRect selfFrame = self.view.frame; 
    CGFloat aWidth = masterController.view.frame.size.width;

    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.30f];

    if(orientation == UIDeviceOrientationLandscapeLeft)
    {
        selfFrame.size.height += aWidth;
        selfFrame.origin.y -= aWidth;
    }
    else if(orientation == UIDeviceOrientationLandscapeRight)
    {
        selfFrame.size.height += aWidth;
    }

    [self.view setFrame:selfFrame];

    [UIView commitAnimations];

}

This is the starting point, obviously more logic needs to be done to take care of rotation, showing it again, etc...

I hope this helps.
