Best approach for Nested UINavigationController - ios

Question

I have two viewControllers for iPad just like facebook sidepanel. There is LeftViewController which toggles when I click a button on center viewController. It slides on the top of CenterViewController. But it covers only 50% of centerViewController.
I should be able to add new views to left viewController and can push.
What is the best approach to achieve this.

Answer 1

Please check this link
Sliding Drawers
[SideMenus]
This contains different drawers and few in swift too. may be this link would be helpful to you.

Answer 2

you can add slide-in side bar in view.see below my code.
assign the property in .h file
UIView*menuDrawer;
#property(readonly,nonatomic)UISwipeGestureRecognizer*recognizer_open,*recognizer_close;
#property(readonly,nonatomic) int menuDrawerX,menuDrawerWidth;
//customize slide menu
Add this code in viewdidload
int statusBarHeight=[UIApplication sharedApplication].statusBarFrame.size.height-20;
menuDrawerWidth=self.view.frame.size.width*0.65;//you can adjust width
menuDrawerX=self.view.frame.origin.x-menuDrawerWidth;
menuDrawer=[[UIView alloc]initWithFrame:CGRectMake(menuDrawerX, self.view.frame.origin.y+statusBarHeight, menuDrawerWidth,self.view.frame.size.height-statusBarHeight)];
menuDrawer.backgroundColor=[UIColor
whiteColor];
recognizer_close=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:#selector(handleSwipes:)];
recognizer_open=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:#selector(handleSwipes:)];
recognizer_close.direction=UISwipeGestureRecognizerDirectionLeft;
recognizer_open.direction=UISwipeGestureRecognizerDirectionRight;
[self.view addGestureRecognizer:recognizer_close];
[self.view addGestureRecognizer:recognizer_open];
[self.view addSubview:menuDrawer];
add this method
-(void)handleSwipes:(UISwipeGestureRecognizer*)sender
{
[self drawerAnimation];
}
call this method,if you are assigning a button also can set selector of a button
-(void)drawerAnimation
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:-5];
CGFloat new_x = 0;
if (menuDrawer.frame.origin.x < self.view.frame.origin.x) {
new_x=menuDrawer.frame.origin.x + menuDrawerWidth;
}
else
{
new_x=menuDrawer.frame.origin.x - menuDrawerWidth;
}
menuDrawer.frame=CGRectMake(new_x, menuDrawer.frame.origin.y, menuDrawer.frame.size.width, menuDrawer.frame.size.height);
[UIView commitAnimations];
}
it will work fine,you can add UITableView or other controls in these slide-in side bar menu.
you can adjust height and width via statusBarHeight and menuDrawerWidth.
