ScrollView Swipe Right not working XCode - iphone

Question

I've a scrollView in which subviews are added and these subviews can be swiped top, right and left. But for some reason the swipe right does not seem to be working at all. I'm completely new to Objective-C, due to which i've been struggling real hard to make it work. I've a main view controller implementation with following code:
my MainViewController.m is
- (void)viewDidLoad {
[super viewDidLoad];
_headerViewController = [self.storyboard instantiateViewControllerWithIdentifier:kHeaderId];
_headerViewController.delegate = self;
[scrollView addSubview:_headerViewController.view];
_actionsListViewController = [self.storyboard instantiateViewControllerWithIdentifier:kActionsListId];
_actionsListViewController.delegate = self;
[scrollView insertSubview:_actionsListViewController.view
belowSubview:_headerViewController.view];
_agendasListViewController = [self.storyboard instantiateViewControllerWithIdentifier:KAgendasListId];
_agendasListViewController.delegate = self;
[scrollView insertSubview:_agendasListViewController.view
belowSubview:_headerViewController.view];
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self positionSearchField:YES];
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * 2,
scrollView.frame.size.height * 2);
_headerViewController.view.frame = CGRectMake(0, 0,
scrollView.frame.size.width,
scrollView.frame.size.height);
//action view will be displayed when swiped left
_actionsListViewController.view.frame = CGRectMake(scrollView.frame.size.width, 0,
scrollView.frame.size.width,
scrollView.frame.size.height);
//agenda view should have been displayed when swiped right
_agendasListViewController.view.frame = CGRectMake(-scrollView.frame.size.width, 0,
scrollView.frame.size.width,
scrollView.frame.size.height);
_scrollViewBounds = scrollView.bounds;
}
and the viewShouldScroll function
- (void)viewShouldScroll:(UISwipeGestureRecognizerDirection)direction {
CGRect frame = CGRectMake(scrollView.contentOffset.x,
scrollView.contentOffset.y,
scrollView.frame.size.width,
scrollView.frame.size.height);
UIViewController *currentController = [self visibleViewController];
switch (direction) {
case UISwipeGestureRecognizerDirectionUp:
frame.origin.y += scrollView.frame.size.height;
break;
case UISwipeGestureRecognizerDirectionLeft:
//works fine and displays action view
frame.origin.x += scrollView.frame.size.width;
break;
case UISwipeGestureRecognizerDirectionDown:
frame.origin.y -= scrollView.frame.size.height;
break;
case UISwipeGestureRecognizerDirectionRight:
if( currentController == _headerViewController ) {
//does not work for agenda when swiped right
NSLog(#"x position is %f#", frame.origin.x);
frame.origin.x = -320; //hardcoded to check if this works, but doesnot
NSLog(#"width is %f#", scrollView.frame.size.width); //gives -320
}
else {
//works fine when swiped from left to right to show main view
frame.origin.x -= scrollView.frame.size.width; //0
}
break;
default:
break;
}
[scrollView scrollRectToVisible:frame animated:YES];
}
Gesture recognizers have been added from storyboard for LEFT, RIGHT and TOP. As per the code, i've added agenda view with position of x as -320 in CGRectMake and on swipe right, i'm trying to make it visible by changing the x point of frame.origin but it does not seem to work. Any help would be appreciated.

I managed to do it this way::
...
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * 3,
scrollView.frame.size.height * 2);
...
I was using the width of scrollView as scrollView.frame.size.width * 2, which made the total width of scroll view double of scrollView.frame.size.width, but since i had 3 subviews in the main scrollView, i needed to do create scrollView with width 3 times the width of scrollView frame as scrollView.frame.size.width * 3
