I have UITableView with SVPullToRefresh. Above this UITableView I have a view with UITextField, buttons etc.
(Ex: .
I would like to implement such thing: when I scroll down my tableView I would like to scroll this header too. (This could be easy created with Table header, but as I said I am using pull to refresh). And when I start to scroll up - immediately appeared. Sorry for my poor english. Help me out.
P.S. I am using autolayout

In Swift, is there a way to change scrollview focus programatically? For example, in one of my scrollviews when a user is scrolling, after the scroll has gone past a certain distance I want the scroll to stop scrolling and to immediately scroll a tableview instead. I want this to all happen in the same motion/swipe, so I need to automatically shift the focus from the scrollview to the tableview using code. Is this possible?
Using Rikh's comment, I was able to solve this using a UITableView with multiple sections and custom UITableView headers. I can use the viewForHeaderInSection method to create a custom floating header which is exactly what I need and it scrolls much more smoothly.
I'm working on a application where I have a UITableView inside a UIScrollview.
The TableView will display current games players are in, its inside a UIScrollView. I dynamically add cells to the UITableView for each game, but when I scroll the UIScrollView, the tableview inside it snaps back to its size set in the storybuilder.
This is because of autolayout, when I disable it, it doesn't happen anymore. However I do like autolayout for other views in my app. So my question is, how can I fix this problem?
Maybe someone can help me get on the right track.
Thanks
EDIT
I think I must explain my situation more, I will use an image where I can display what is happening
Explanation
Before and after scrolling.
As you can see I use the scrollview because there can be many games, so you'll have to scroll down to see them all. The TableView is just to hold the data, scrolling is disabled on that. After scrolling the TableView that says "JOUW BEURT" snaps back to its size set in the Storybuilder. This is because of auto layout like I said, but I don't know how to fix this.
You shouldn't put a tableview inside a scrollview as a tableview itself contains a scrollview and causes issues just like you are seeing when you have a scrollview inside a scrollview.
Remove the scrollview and this should fix your issue. If you are wanting to put content above the tableview or where you scroll down to view the tableview cells etc, consider adding a tableview header view that is added above the tableview.
Why did you place UITableView inside UIScrollView?
Check below
Check your constraints of UITableView and UIScrollView
Placing UITableView inside UIScrollView is somewhat strange
EDIT
You will just need to remove the scrollview and enable scrolling feature of the tableview. that will fix it
UITableView is already a subclass of
UIScrollView
If you look at the Featured tab of the Apple App Store app on an iPhone 6, there is a unique UI layout that I can't figure out how to replicate.
At the very top there is a navigationBar. Below this there is a UIScrollView that animates through a number of featured items. Below this is what appears to be a UITableView with a number of custom programmed cells.
My first guess was that the UIScrollView at the top was added to a custom cell at the top of a UITableView. If you swipe up the UIScrollView moves with the objects below like it is a cell. You can see that the vertical scroll indicator starts at the top of the UIScrollView.
The part that is unique is that if you swipe down, the objects below the UIScrollView move down like a UITableView and the UIScrollView stays in place. This means that the UIScrollView is not a custom cell at the top of a UITableView.
I tried making this work a number of different ways but I can replicate this. Does anyone know how this can be done?
You can use a tableview header,the header is a scrollview
If you scroll tableview up,just use tableview default behavior,the header will scroll up.
If you scroll down,use UIScrollViewDelegate to calculate the tableview header new frame,and adjust it.So it remain at top
Not sure if I got you correctly, you may use UICollectionView as vertical scroll. Then, you create a custom UICollectionViewCell, each with horizontal scroll.
I haven't tried it though but done something similar to this. Hope you find a way!
In this I need scroll complete tableview to upward and tableview should stay upwards until user again scrolls down. It should come back to its original position.
Update
I need to scroll the tableview top and bottom on a image
From Apple documentation it's not advisable to add tableView inside scrollview(Reference).
Now according to design of your screen either you can have one tableView and in header of that tableView you can add all static content.Reference
or if your design must have tableView inside scrollView then this SO question maybe helpful to you.
I'd prefer first choice if possible.
By the way if you can fix the height of tableView then you can implement tableView inside scrollView easily.
I have two Scenes in my Storyboard that are nearly identical. Both are UITableViewControllers. Both have header and footer views. The header views have a UISearchBar and the footer views have a UIView that contains a UITextField. Each have only one prototype cell. One is prototyped as a "Basic" cell and the other is prototyped as "Right Detail" cell.
Here's the problem. When I click the UITextField in the footer view on the first scene, the table resizes automatically so that the bottom of the table is at the top of the keyboard. This allows me to scroll the table up so the footer view shows and the user is able to see what they're typing. The other scene will not automatically resize the UITableView so the UITableView cannot scroll the footer view to where it can be seen and the UITextField is hidden under the keyboard. I can't even manually scroll the table far enough since the footer is always at the bottom of the UITableView.
A little added info. The scene that works has many rows of data while the one that doesn't work only has a couple. I tried adding a number of rows until the table had enough to enable scrolling and it doesn't fix the problem.
I have checked everything I can think of and I can't see anything that would allow one of the views to let the UITableView to automatically resize to work with the keyboard and the other not. I must have overlooked something but I can't seem to find it.
Any help will be greatly appreciated!

I thought this problem was caused by copy-and-pasting from one view to another, but I had the same problem once I'd (in theory) fixed it.
The answer for me turned out to be simple: I hadn't called [super viewWillAppear:animated] in my UITableViewController subclass' viewWillAppear: implementation. Make sure you've got a call to the superclass' method and hopefully the problem will go away.
I am guessing the frame of the tableview is not being resized to the smaller size in the second case.
Print out the frame and content sizes in both the cases once its loaded, that should help you see if there is an issue.
