#define RIGHT_PANEL 2
#define CENTRAL_TAG 1
#define SLIDE_TIMING .25
#define PANEL_WIDTH 60
#interface MainViewController ()<CenterViewControllerDelegate>
#property(nonatomic,strong)CentralViewController *centralView;
#property(nonatomic,strong)RightViewController *RightView;
#property (nonatomic, assign) BOOL showingRightPanel;
-(UIView*)getright;
-(UIView*)resetmainView;
#end
#implementation MainViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.centralView = [[CentralViewController alloc] initWithNibName:#"CentralViewController" bundle:nil];
self.centralView.view.tag = CENTRAL_TAG;
self.centralView.delegate=self;
[self.view addSubview:self.centralView.view];
[self addChildViewController:_centralView];
[_centralView didMoveToParentViewController:self];
}
-(UIView*)getright
{
if(_RightView==Nil)
{
self.RightView=[[RightViewController alloc]initWithNibName:#"RightViewController" bundle:Nil];
self.RightView.view.tag=RIGHT_PANEL;
self.RightView.delegate=self;
[self.view addSubview:self.RightView.view];
[self addChildViewController:self.RightView];
[_RightView didMoveToParentViewController:self];
_RightView.view.frame=CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
}
self.showingRightPanel=YES;
UIView *view=self.RightView.view;
return view;
}
-(void)MovetoOriginal
{
[UIView animateWithDuration:SLIDE_TIMING delay:0 options:UIViewAnimationOptionBeginFromCurrentState
animations:^{
_centralView.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
}
completion:^(BOOL finished) {
if (finished) {
[self resetmainView];
}
}];}
-(void)rightpanelmove
{
UIView *child=[self getright];
[self.view sendSubviewToBack:child];
[UIView animateWithDuration:SLIDE_TIMING delay:0 options:UIViewAnimationOptionBeginFromCurrentState
animations:^{
_centralView.view.frame = CGRectMake(-self.view.frame.size.width + PANEL_WIDTH, 0, self.view.frame.size.width, self.view.frame.size.height);
}
completion:^(BOOL finished) {
if (finished) {
_centralView.rightbutton.tag = 1;
}
}];
}
-(UIView*)resetmainView
{
if(_RightView!=Nil)
{
[self.RightView.view removeFromSuperview];
self.RightView=Nil;
_centralView.rightbutton.tag=0;
self.showingRightPanel=NO;
}
This is my main control code where am calling the event
And this one is button action code
- (IBAction)btnright:(id)sender {
UIButton *button = sender;
switch (button.tag) {
case 0: {
[_delegate rightpanelmove];
break;
}
case 1: {
[_delegate MovetoOriginal];
break;
}
default:
break;
}}

Answer 1

-(UIView*)resetmainView
{
if(_RightView!=Nil)
{
[self.RightView.view removeFromSuperview];
self.RightView=Nil;
_centralView.rightbutton.tag=0;
self.showingRightPanel=NO;
}
UIView *view=self.centralView.view;
return view;
}
This what i missed now it is working!!!!
