I'v some strings of different size in an array, i added them to UIScrollView by using UILabel
user can scroll horizontally to see all the names.But i want when user scroll either side he should see next/previous name from list as we do in paging enabled scroll view but here i want only one name(of different size) to be scrolled, not the whole screen.How to achieve this?Any help or suggestion would be highly appreciated.
Edit: - for better understanding suppose initially 0th, 1st and 2nd strings from my array is visible on scroll view, and when user scroll it should show 1st, 2nd and 3rd strings from my array(and vice versa for scrolling to other side).
You can do this by contentoffset.
set contentoffset of scrollview and you can able to do this.

I am trying to recreate a UIView I have seen in multiple apps, mainly Shazam. The top half of the screen has some interactive buttons, and the bottom half looks like a tableView with custom cells. When the bottom half is panned/swiped up, the tableView scrolls over the top half with velocity, much like a scroll view.
I have been researching this and experimenting for a couple days now. I have gotten close, but not quite there.
My last approach was a view that had a tableView inside it. When the view was panned, the view would move to wherever the finger moved it to, but then would not have any velocity afterwards. Also when the tableView was panned/swiped down, it wouldn't move the whole view down.
Before that I tried a scrollView that took up the whole length of the screen. That gave the desired effect, but the button wasn’t tappable, and you could scroll the view in the button area, which is undesired.
Does it utilize ScrollViews or is it using a tableView that acts much like a ScrollView somehow.
Here is the Shazam UI/UX I am looking to recreate:
The top portion has interactive buttons, and doesn’t scroll. The bottom half shows content and when scrolled, covers up the top portion.
Below is what I have tried so far: This one is the panning view, which sort of works, but doesn’t have velocity and the tableView doesn’t scroll the view back down.
Any thoughts on a direction I can take from here is greatly appreciated. I am using Swift.
Cheers
This sort of thing is perhaps best done with a collection view and a custom layout — you can have some items for which you set layout attributes absolute to the view, and others relative to the scroll content offset.
There's a great (if wandering) discussion of this and other techniques in the Advanced User Interfaces with Collection Views talk from WWDC 2014.
This is actually simple than it seems at first. Here's how you can achieve this:
Create a UIViewController (not a UITableViewController).
Add some buttons to the top area of the screen.
Add a table view spanning the entire view controller's view. Make sure the table view is on top of the buttons added in the previous step.
Configure the top cell of the table view to be transparent (by setting its background color to Clear). Set the background color on the table view to Clear as well. This way it won't obscure the elements at the top of the screen, unless the table is scrolled up.
Because your table view is now transparent, you'll need to explicitly set the background color on the table cells other than the top one.
Profit!
I have the following layout
So it's basically a scroll view that occupies whole screen. Content size is set to triple-width and same height. Inside the scroll view - there is container view and three table views - one per page. Only middle table view is visible initially.
This allows me to use scroll view horizontal scrolling to navigate between the tables and vertical scrolling inside the middle table.
I know that Apple doesn't really recommend putting UITableView inside UIScrollView, but in this particular case I don't know how to implement it differently, and until iOS8 everything was working fine.
UIScrollView would not recognize any vertical scrolling (since content height was equal to scroll view height) and these gestures were passed directly to UITableView.
But starting in iOS8 - this getting broken. UIScrollView would allow some vertical scrolling and basically intercept scrolling gestures sent to UITableView.
I created a simple project that works fine in iOS7 but is broken in iOS8. Anybody has any idea how to fix this problem?

I haven't been able to solve this and as I mentioned in comments had to re-write logic using built-in UIPageViewController class.
If I change the Class of your ScrollView in Interface Builder to UIScrollView, it fixes part of the problem. Now just the UITableView goes up and down, and I go left-and-right, but haven't gotten rid of the space at the top.
I have a UIScrollView on my screen and there are some UIButtons on the scroll view.
I also have a UITableView which is above the scroll view, i.e. the tableview and the scrollview are overlapped.
Why I did this is because I want left and right swipe to flip pages of the scroll view and up/down swipe to show some text on the tableview.
This works fine except the button on the scroll view cannot be tapped. It seems that the tableview "absorbed" the tap event and it did not pass it to the button on the scrollview.
Is there someway to fix this? Thank you.
This could be a solution but I'm not sure of it because from your question I can't understand your problem very well, you can try it but if it doesn't work we will try a different way. Maybe the problem is the arrangement of the UI elements in your Interface Builder/Storyboard. If I correctly understood your situation you have something like this:
To make to UIButtons clickable you have to be sure they're at the highest level of arrangement inside the UIScrollView since the UITableView could cover them and "absorb" [as you said] the touch input. So my suggestion is: arrange your UI elements following the blue arrow in the picture below, placing the UIButtons on top, in this way they'll be 100% clickable.
If I didn't understand your question could you please shoot a picture like the one I've posted so I can understand it better?
I have a problem, it is not so much about a bug, but rather how to approach the issue.
I wanna create a UICollectionViewLayout where I can scroll a single column. Normally when
we scroll a scroll view, all the subviews scroll up/down/left/right. But here I wanna have a set of columns, and basically as user scrolls vertically, I want to only scroll that column and leave the others where they were. More over if the user scrolls horizontally I want the normal behavior, that is, all columns scroll left or right.
Any idea how to approach this problem ?
It's a little late, but, better late than ever!
You are right in that you need to rock your own UICollectionViewLayout. I recommend you start with having it work normally before you start working on your particular behaviour.
Basically what you want to do is have all cells but one column be vertically sticky.
To achieve that, you need reposition all your cells (but the ones that actually move) based on the Collection View's xOffset and yOffset.

For this you can use a UITableView with custom UITableViewCell containing UIScrollView and you can set scrollview to scroll in desired direction.
I have a UISCrollview loading webviews, as the user starts scrolling to go to the next page, I need to have the the coming webpage to scroll into the screen from underneath another UIView that is stationary, I tried changing the alpha but its not really what I am looking for. how can I accomplish that?
For example, the scroll direction is top to bottom, now I have a uiview at the top of the screen which has some static data showing ( title, location, and other text labels ), and as the user scrolls down I want the content to scroll underneath the label ui view. Hope this clarifies it.
If I understand this question correctly I'd say you can't do this with a UIScrollView. Instead, you could have separate views for each UIWebView and handle the panning of one view under another with a UIPanGestureRecognizer.
Also, did you know there can be conflicts when using UIWebView's inside UIScrollView's?
