@interface ViewController <PWParallaxScrollViewDataSource>

implement PWParallaxScrollViewDataSource methods

- (NSInteger)numberOfItemsInScrollView:(PWParallaxScrollView *)scrollView;
- (UIView *)backgroundViewAtIndex:(NSInteger)index scrollView:(PWParallaxScrollView *)scrollView;
- (UIView *)foregroundViewAtIndex:(NSInteger)index scrollView:(PWParallaxScrollView *)scrollView;

setting ForegroundScreenEdgeInsets

About ForegroundScreenEdgeInsets

custom your parallax offset

foregroundScreenEdgeInsets = UIEdgeInsetsMake(0, 30, 0, 100);

sample code

    self.scrollView = [[PWParallaxScrollView alloc] initWithFrame:self.view.bounds];
    _scrollView.foregroundScreenEdgeInsets = UIEdgeInsetsMake(0, 30, 0, 100);
    [self.view insertSubview:_scrollView atIndex:0];
    

- (UIView *)foregroundViewAtIndex:(NSInteger)index scrollView:(PWParallaxScrollView *)scrollView
{
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 30, 300, 70)];

	...
	    
    return label;
}

Normal

foregroundScreenEdgeInsets = UIEdgeInsetsZero;

sample code

    self.scrollView = [[PWParallaxScrollView alloc] initWithFrame:self.view.bounds];
    _scrollView.foregroundScreenEdgeInsets = UIEdgeInsetsZero;
    [self.view insertSubview:_scrollView atIndex:0];
    

- (UIView *)foregroundViewAtIndex:(NSInteger)index scrollView:(PWParallaxScrollView *)scrollView
{
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 30, 300, 70)];

	...
	    
    return label;
}

hit test

- (UIView *)foregroundViewAtIndex:(NSInteger)index scrollView:(PWParallaxScrollView *)scrollView
{
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 30, 300, 70)];
	...
    
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
	...
    [button addTarget:self action:@selector(test) forControlEvents:UIControlEventTouchUpInside];
    ...
    [label addSubview:button];
    
    return label;
}

moveToIndex , prev , next

sample code

    [scrollView moveToIndex:3];

    [scrollView prevItem];

    [scrollView nextItem];

background view only

just not implement the foregroundViewAtIndex:scrollView: method (or return nil)

- (UIView *)foregroundViewAtIndex:(NSInteger)index scrollView:(PWParallaxScrollView *)scrollView;

pwparallaxscrollview's Issues

UITableView Doesn't Work in Foreground

in foreground, i added UIViews and in UIViews i added UITableView, when i run that code all things displays perfectly

but when i touch on tableview, nothing happen on tableview...

Adding UIViews with UITableView as background objects

Hi,

It looks like PWParallaxScrollView does almost exactly what I need so I'm trying to include it in my project.

However, I've come across a problem: I need to add some objects extending UIView as background objects. These objects all contain a UITableView that is scrolled vertically. When I do that, I can't scroll the UITableView.

I examined your source code but couldn't find anything obvious which could be the cause of my problem.

Is it possible you could help me with this?

Add border line between images

How to make this scrollview to scroll infinate?

How to use this scrollview in my project to make it scroll infinitely, for instance when you at last page you can swipe it to first page ,some thoughts would be great,thx

Calling moveToIndex right after creation (in viewWillAppear) doesn't work

It seems that the page I try to display is somehow in the background, and what I see is a part of previous photo.

calling [self loadBackgroundViewAtIndex:index]; in moveToIndex resolves the issue

TableView can't scroll

When i add uitableview in foreground i can't scroll it.
