How can I detect if webview can't scroll vertically anymore? I have the auto scrolling method and I want to make sure it stops after the content has fully displayed.

I have a UITableView with cells. One of the cells has a full size UIWebView.
On the web view I want ONLY to enable horizontal scroll (like coverflow).
I can do that with this ansawer: https://stackoverflow.com/a/12575036/406055
But: Then the UIWebView intercepts the vertical scroll (thus without performing it). I want the vertical scroll gesture to affect the tableview, not the web view.
The idea I have is to either overlay the web view with a UIView and add gesture recognizers and then pass the gesture on to the UIWebView only if it is horizontal.
But any other suggestions is welcome too.
I made a Content View inside Scroll View added constraints using common Autolayout with UIScrollView tutorials. But how do I stop my Scrollview from scrolling up when there is no content, the view slides down to content, but I want to disable scrolling up, I searched for the answer but there is none to be found, please help.
The ability to scroll slightly beyond the content in a UIScrollView is referred to as "bouncing".
The scroll view must know the size of the content view so it knows when to stop scrolling; by default, it “bounces” back when scrolling exceeds the bounds of the content.
You need to set bounces to no:
If the value of [bounces] is YES, the scroll view bounces when it encounters a boundary of the content. Bouncing visually indicates that scrolling has reached an edge of the content. If the value is NO, scrolling stops immediately at the content boundary without bouncing. The default value is YES
scrollView.bounces = NO;
Is there possibility to scroll content inside the slide on touch devices? My content has vertical scroll bar at desktop view, but on touch devices I can't scroll content at all. I guess scroll event is catched by library and is treated as scrolling to nested vertical slides. I will be happy to get some help here, thank you in advance.
So I've got a UIScrollView that has an image inside, and below that I have a webView. How can I make it so that when I scroll the webView up/down, the scroll view also scrolls up/down? Like when you scroll in Safari, the URL bar moves along with it.
Here's what I'm using:
first add the UIWebView and UIScrollView+UIimageView within an
another UIScrollVIew
disable the native scrolling of UIWebView byt iterating its subviews
disable the scrolling of the UIScrollView which consists UIImageView
by doing this way will help your cause
i have a scrollView that fits the whole screen. In that View i show some UIImages that scroll horizontally. Like in the PageControl Project from Apple.
Then, when the user taps the screen, i fade in a scrollView at the bottom with some other images. Also horizontally scrolling. Like in the ScrollView Project from Apple.
My problem is, that when i come to the end of the scrollView which was faded in, the upper scrollView also starts to drag. How can i stop that during activation of the second scrollView?
Redraw the frame limits on your first scrollView when the second enters the screen. That way, your touches won't respond to both views. This means you need a container-view to keep both views seperated from each other.
Then you just rescale it back whenever your second scrollView disappears.
Edit: or disable scroll in your first scrollview while the second is open.
