I am fairly new to iOS Swift Development and I am currently designing UI for my mobile application and the goal is to produce something similar to HTML Table with header on the left and content on the right like follows:
Currently I have achieved it by using multiple Stack Views and stacking it against one another in the following manners:
However this has caused my Xcode to be very slow (I assume it is caused by stacking too many things and it uses memory).
Therefore I would like to know whether there are other more efficient ways to achieve the same result (produce the same design).
Thanks in advance.
Why don't you use tableview? Add two labels in each cell on left size and right side. Set the style of cell to right detail if you want to use the default configuration.

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.
For iOS 7 and iOS 8, we're implementing these things that look like drop-downs, but each just launch a modal window.
What makes more sense, using 3 UIButtons, 3 UITableViews with 1 row, or something else? In the past, there would be more than one of these all lined up, so I would put them in a UITableView and set the accessoryView of the UITableViewCell. Using the cell was nice, but three UITableViews seem like overkill here and a maintenance hassel.
The closest post I found regarding this was one about using an UITableViewCell outside of UITableView
What would make the most sense is to follow the iOS design guidelines. Instead of trying to create custom dropdown menus (or worse: showing a drop down menu, but displaying a modal view when the user is expecting a drop down view), that UI could be replaced with 1 UITableView that has 3 UITableViewCells in it. The text on each cell would be the name of the setting to be changed and selecting the cell would push segue to the next page. This will give the app a uniform iOS UX; allowing users to know exactly how to use your app because it works similarly to other apps on their phone. Check out the Settings app on the simulator to see what I am describing.
I don't see any advantage to using a UITableView or a UITableViewCell. I think this is clearly a case for three UIButtons. You can set constraints to keep them nice and clean. One cool thing that might be worth investigating is using a unicode character for the downward arrow. That way you could have the tap feedback on the whole "thing" as you called it.
When I need to create sort of dropdown menus, I usually take advantages from UITableView, one above all is when you will need to add one or more selections in the dropdown you just need to change the data model.
UITableViewCells are easily customizable that means that you can create almost everything you want.
I think that your design doesn't adapt well to a mobile application, those kind of menu are more web style, with 3 buttons and a UIPickerView you can really improve the user experience and also adapt in a really easy way on the ipad embedding the picker in a UIPopoverController.
as i agree with #keithbhunter, but still if you want then may this links will help you.

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
I'm new to iOS development. I have finished the "console" part of my app (it does what I need it to do in a Mac app without a UI), but now I have no idea on where to start for my (iOS) UI part.
Basically, I need something like a simple grid of cells (like Excel); my code reads a file, creates a dynamic (varies per file content) 2D array, and I want to show this on my UI, making each cell selectable by the user (each cell would correspond to a position in my 2D array).
Could someone point me in the right direction (even if its only the name of the classes I need to look up in apple's doc.)? I have been trying to find answers online, but it seems I'm not looking for it right.
In case I didn't explain myself correctly, I want something like this:
UICollectionView is the correct class to use for this. It allows you to create layouts with multiple rows and columns in a similar style to UITableView. You can also create your own custom layouts if the default one does not do what you need.
I am currently working on an iPad application that uses a table view to present data, I was inspired by the iTunes application in iPad that present it's data in multiple columns in a very nice and neat manner, and the most interesting thing is that during the portrait mode the itunes application displays data in 2 columns but when the user switches to landscape mode, it switches the display to 3 columns (since there are plenty of space to display data horizontally).
This is what i'm talking about:
but i found out that iOS SDK only supports single column for tableview (it would be nice to utilize the entire space provided on iPad screen to present data), i did some research and i found out that the best way to present data in multiple columns yet like spreadsheet style is to use datagridview instead, but iOS SDK did not provide any data grid view controls for iOS developers.
I found out over the internet some customized tables like:
AQGridView.
DTGridView.
and also the one from this:
http://usxue.is-programmer.com/posts/14176.html
and the one from this:
http://xebee.xebia.in/2011/04/14/building-editable-gridview-for-iphone-apps/
But sadly none of these ever met the requirements of the application i was working on.
Could you guys provide me some ideas or share some sample codes or links on how to display data in somehow-data grid view, to achieve similar effect used in iTunes application (as shown above).. Any form of help would be pretty much appreciated. Thank you guys!
The summary answer is, place multiple data "views" across in a single cell.
The more detailed answer:
Create custom views that represent the single cells you want. You can for this purpose make them resizable enough to work two across or three across (they will get loaded into 1/2 or 1/3 of the cells bounds).
Then make a custom UITableView cell, that can take two or three data items - load up an instance of the custom view previously created in the cell for each data item you have, placing them next to each other. You can have the cell do the view layout when groups of data items are added.
In the cellForRow code in the table delegate/datasource, you use your data source in groups of two or three (and report the row count accordingly) to pass along to the custom cell.
Sorry I can't share code, but I have used this technique before in other applications.
What's wrong with creating a UIView class to represent a single cell, and another that lays out an array of those cells in a grid? Put your grid view in a UIScrollView and you're about done.
UITableView is obviously a pretty complex class. Much of that is to make it very general, very reusable, and able to support a huge number of rows. Your class doesn't necessarily need to be that complicated -- if you have a fairly small number of cells, your "grid" could really just be a UIView in which you lay out cells in rows and columns. UITableView removes cells that aren't seen in order to save memory; you might need to do something similar if you have hundreds of cells, especially if they're large, but a few dozen probably won't require that.
In short, since you need a grid view for a particular use, you don't need to do all the extra work that would be required for a general, reusable solution.
