I'm trying to create the effect seen in some iOS apps where swiping the screen scrolls the ScollView/TextView normally, but sliding on the far right (where the scroll indicator is) creates a quick scrolling effect that allows the user to scroll through the position in the overall length of the view. For example, sliding on the far right from the middle of the screen to the bottom would take the TextView from the middle of its content to the very end.
Is there any pre-established way to do this, or is this an effect I would have to create from scratch?
Thanks a lot for any help, and I'm sorry if this question wasn't very clear.

Maybe a bad title, but I did my best.
Here's what I have: A menu on the left side, which can be opened by panning (from a small vertical bar to almost half my view). The designer thought it a good idea to insert a horizontally scrolling menu right there.
I made all this, but when I scroll horizontally in my menu (so not opening or closing the menu), I can't close the menu by swiping the scrollview more to the left, because it bounces (it also does not work when bouncing is off).
Does anyone have an idea how I can trigger my UIPanGestureRecognizer when the UIScrollView is scrolled beyond its right edge? Or any other idea how I can solve this?
The reason I made this title is because I have all the code for opening and closing the menu in my UIPanGestureRecognizer, and I think it's better if I just trigger the recognizer instead of re-writing some code.
So I am trying to figure out how to make a circular scrolling system. So I have for example a wheel like this http://static.cubiq.org/uploads/2009/04/Rotating-wheel.jpeg and you scroll between options (like an old school ipod) Now I currently already have this working with positions. So I have positions 1-6 and as you scroll down, it moves everything down a position and I animate this transition. I am wondering if there is a way to do this using the actual scroll function. So that you can scroll up and down freely while holding down, rather then doing up or down actions and waiting for animation.
So given that information how could I convert a standard vertical scroll up->down and down->up into a circle structure. Thanks for any info
i'm trying to apply a shift effect to subviews of a UIView, but those shifts should'n have the same phase. A good example of that is the welcome screen in SoundClound.
As you can see, in the second image i'm scrolling to the second page, and the label slides more than the image (so it looks that the label moves faster than the image). So the subviews lose the alignment when scrolling, but recover it back if we stop the swipe.
Does anyone know how this effect is named? and where can i find some help to implement it?
Thanks a lot!
"Parallax scrolling" is what you want to search for.
Basically it is done by moving foreground objects faster background objects to simulate depth.

I have three table view.
Left side tableView is CourseTableView
Top table table is MonthTableView
Center one is DurationTableView.
I already implemented the functionalities if is scroll DurationTableView either left or right direction MonthTableView also scroll with it. same if scroll MonthTableView either left or right direction DurationTableView also scroll with it.
Same way if i scroll DurationTableView either up or down direction CourseTableView scroll with it same vice versa.
Now i have to implemented if i scroll DurationTableView left or right means CourseTableView shrink to smaller size like sliding the view and DurationTableViewSize should get enlarge up to reset of the space.
if i stop the scrolling of DurationTableView then CourseTableView again should come back to previous size.
How can i achieve this, kindly suggest me. if u have any tutorial for this kindly mention here.
Thanks in advance

I have a horizontal scroll view with paging enabled, and the children of this scroll view are vertical scroll views. It's like the iOS home screen, but imagine scrolling vertically on each home screen.
Now, when the vertical scroll is in progress, it's hard to swipe to the next or previous screen, because the vertical scroll view apparently captures the events. Even if the angle of the swipe is almost horizontal, it doesn't go to the next or previous "page". Only after the scroll stops fully can one easily swipe to the next or previous pages.
Unfortunately, because of the slow deceleration, the user might think the content stopped moving when it is in fact moving very slowly and just about to stop. But the horizontal swipe is interpreted as a vertical scroll gesture, and the scroll velocity increases, making things worse from the user's perspective.
I've noticed multiple people struggling with this when they test out our app, and I wonder if anyone here knows a solution, perhaps a way to consider the angle of the swipe to determine which scroll view should process the event. Thanks.
I would suggest stopping the vertical scroll on a touch begins event. This is how most apps I've seen do something like this.
