Navigating from ScrollViewController Content view to another view on stack - iphone

Question

I am trying to navigate from a UIScrollView's content view to another view by using a UIButton. I do not want to display this other view modally, and pushing the view on the stack is not working for me.
Example:
My Viewcontroller contains a Scrollview that has 2 content views. Within these content views I would like to push another view onto the stack.
Is what I am trying to do possible?

Ok let's see if I understood well enough your problem.
#interface MyViewController ()
#property (nonatomic, strong) UIScrollView *scrollView;
#property (nonatomic, strong) UIView *firstPlayerView;
#property (nonatomic, strong) UIView *secondPlayerView;
#end
#implementation MyViewController
-(UIView *)firstPlayerView
{
if (!_firstPlayerView) {
_firstPlayerView = [[UIView alloc] initWithFrame:self.view.bounds];
// set up your view as you like and place the button to go to the second player
// view when you need to.
// let's suppose that you called that button "goToSecondPlayerViewButton"
[goToSecondPlayerViewButton addTarget:self
action:#selector(switchPlayer)
forControlEvents:UIControlEventTouchUpInside];
}
return _firstPlayerView;
}
-(UIView *)secondPlayerView
{
if (!_secondPlayerView) {
_secondPlayerView = [[UIView alloc] initWithFrame:CGRectOffset(self.view.bounds, self.view.bounds.size.width, 0)];
// set up your view as you like and place the button to go to the first player
// view when you need to.
// let's suppose that you called that button "goToFirstPlayerViewButton"
[goToFirstPlayerViewButton addTarget:self
action:#selector(switchPlayer)
forControlEvents:UIControlEventTouchUpInside];
}
return _secondPlayerView;
}
-(UIScrollView *)scrollView
{
if (!_scrollView) {
_scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds];
_scrollView.autoresizingMask = UIViewAutoresizingNone;
[_scrollView addSubview:self.firstPlayerView];
[_scrollView addSubview:self.secondPlayerView];
_scrollView.contentSize = CGSizeMake(self.view.frame.size.width * 2, self.view.frame.size.height);
_scrollView.pagingEnabled = YES;
_scrollView.scrollEnabled = NO;
_scrollView.bounces = NO;
_scrollView.showsVerticalScrollIndicator = NO;
_scrollView.showsHorizontalScrollIndicator = NO;
}
return _scrollView;
}
-(void)switchPlayer
{
if(self.scrollView.contentOffset.x == 0) {
[self.scrollView scrollRectToVisible:CGRectMake(self.scrollView.bounds.size.width, 0, self.scrollView.bounds.size.width, self.scrollView.bounds.size.height) animated:YES];
self.title = #"Second Player";
} else {
[self.scrollView scrollRectToVisible:self.scrollView.bounds animated:YES];
self.title = #"First Player";
}
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
[self.view addSubview:self.scrollView];
self.title = #"First Player";
}
#end
I hope that solves your problem! I haven't tested the code so if you encounter problems just comment and I'll try to help.
Edited : To add a view you just enlarge the scroll view contentSize and add that view as its subview
-(UIView *)thirdView
{
if (!_thirdView) {
_thirdView = [[UIView alloc] initWithFrame:CGRectOffset(self.view.bounds * 2, self.view.bounds.size.width, 0)];
// set up your view as you like
}
return _thirdView;
}
-(void)addThirdView
{
self.scrollView.contentSize = CGSizeMake(self.scrollView.bounds.size.width * 3, self.scrollView.bounds.size.height);
[self.scrollView addSubview:self.thirdView];
[self.scrollView scrollRectToVisible:CGRectMake(self.scrollView.bounds.size.width * 2, 0, self.scrollView.bounds.size.width, self.scrollView.bounds.size.height) animated:YES];
}
You can generalize this and set your content size first then have a single method that takes an index as an argument.
-(void)scrollToViewAtIndex:(NSInteger)index
{
[self.scrollView scrollRectToVisible:CGRectMake(self.scrollView.bounds.size.width * index, 0, self.scrollView.bounds.size.width, self.scrollView.bounds.size.height)
animated:YES];
}
