I want to implement an "accordion" TableView in iOS, something like in this link.
But one small change, I would like the TableView to be at the bottom of the screen, and have the sections expand upwards instead of downwards.
I would like this to be supported in iOS7 and up. Support for iOS6 would be nice to have, but not mandatory.
I've been searching for a solution for the last 3 days and tried many different libraries, but no luck. Any ideas on how to implement something like this? Is this something that's possible to do with any library I use? Or do I need to find something with that specific functionality?
You may try this one library I had Used for something same..https://github.com/vicpenap/VPPDropDown
This is definitely possible.
I don't know whether there is a framework but I can suggest you using simple inserting of table view rows.
Apple doc on table view
But you will definitely need an advanced table row management

Good evening everyone!
Part of my requirements for the app I am building has me creating a data grid similar to the example linked. I have spent the entire day searching google and this site in order to find the best way to get started in swift. I have read so far that both a table view and a collection view could work, but that a collection view is preferred. My data grid doesn't necessarily have to be scrollable but the data does need to be editable. I don't have much experience using either tableviews or collectionviews and I'm looking for the simplest implementation without relying on a third party dependency. Any help or direction is greatly appreciated.
Since I don't know your experience level, I will explain at a basic level - my apologies in advance if it's too basic :) A UITableView displays rows of data, while a UICollectionView displays cells in a grid.
So, at first, a UICollectionView might appear to be the better option. But as always, things get complicated pretty quickly :) For example, are you going to implement your UICollectionView as one cell for the whole row, or are you going to implement a cell per column in your table of data? And if you implement cells per column of data, how are you going to handle the different types of cells you might (or might not) need for each column?
There are multiple decisions that might need to be made, and only you know the answers to a lot of these :)
But the simpler option probably is to go with UITableView and that's what I'd suggest if you are new to both UITableViews and UICollectionView. Try out a UITableView-based approach first and if that doesn't work, or you see limitations, then try a UICollectionView. The experience you had in building the UITableView will help you in moving on to UICollectionView anyway :)
I have played a lot with my app and I do not understand how to make layout like in for example iTunes (also many apps uses it).
How it is made? It is one big CollectionView, but with special Flow or it is TableView with many CollectionView?
Collection headers. In iTunes App if I select item (with adjustImageWhenFocused) under the header then the header will jump up and the item will not overlap the header. It is special magic or it is system behavior and I just do know how to use it?
Below is two screenshots about what I am trying to tell you and example with my app.
In iTunes there are movie preview page. With what type of View it is made? TableView,CollectionView or just ViewController with ScrollView?
I have read many sources and looked up demo projects, but nowhere I have found answers for this questions.
1) I think it would be a stackTemplate containing a couple collectionLists.
2) AFAIK the headers "jump up" on their own, no need to prepare anything special.
3) productTemplate?
For examples, see https://github.com/iBaa/PlexConnectApp, /TVMLTemplates/Default/Movie_OnDeck.xml (1) or Movie_PrePlay.xml (3).
Or check the gold source: https://developer.apple.com/library/tvos/documentation/LanguagesUtilities/Conceptual/ATV_Template_Guide/StackTemplate.html, plus other Templates.
If you want to use native Swift way it can be achieved in following ways:
You can use table view and have collection view within each cell. I am using same approach to achieve this.
We have focus update delegate from there you can find the focused frame of image view. With the help of focused frame and label frame you can check if they are intersecting or not. Based on that you can move label up and down.
This is native TVML template, in order to achieve in swift you need to create view using tableview and collection view.
I'm just wondering what's the best way to do a screen that looks pretty much like the feed view in the Facebook app. I guess the most obvious answer would be to use a UITableView but there are lot of challenges.
There are comments in every feed item and for that we will have to use another UITableView. And that means a UITableView sitting inside a UITableViewCell.
We can't re-use the cells as there are several different content types.
Determining the height of the cell is again a problem as that depends on the number of comments in a feed item.
I'm not planning to do an app that looks like Facebook but this is just a food for thought! I guess there is a better approach that using UITableView. What do you guys think ?
You can design this type of complex interfaces also with hard code but if the code is organised it will save you more time than taking the challenge of using UITableView.
I need a control that closely represents the style of a Spreadsheet in a iOS application I am writing.
Would the UICollectionView provide this appearance?
All I need to do is display data so there would be no editing of the data needed.
Fritzables.
I was looking for something similar a couple of months ago. Ended up writing my own set of classes.
There were a few projects that I checked out on github, see if they are of any use -

You maybe need a UIScrollView where you manage the "Cells" yourself.
Collection views are useful if you need your content to "flow" in some way which I think is not the case here.
You might consider a table view which includes vertical scrolling and row editing etc. but you still have to deal with horizontal offscreen content yourself.
With UIScrollView you have full flexibility to lay out your cells (like tiles) as desired in a fixed way. Panning and zooming is included for free.
I have a regular old UITableView with an index on the right side. I would like to make the index view larger but I do not think you can do this without hacking the API. One could iterate through the UITableView's subviews but that could be very fragile across OS versions. So does anyone know of a sanctioned way to do this?
Yes, you'll have to write your own. Have a look at Customizing Section indexes in UITableView in iphone application, same topic, answer: Do it yourself. The accepted answer provides some steps on how to do it.
