I am trying to create a user profile screen. The screen will have lots of information about a user. It will look similar to this AirB
From the looks of it, it seems to be some sort of scrollView? or is it a tableView or a collectionView? (because it seems that there are some rows in there i think)
Does any one here know how this type of view can be accomplished or can be setup?
EDIT two answers below says to use a UITableview, and 2 other answers says to avoid it. Are there any benefits/disadvantages to using either?
Use only one child UIView as i will call it ContainerView inside UIScrollView and then place your child views inside that ContainerView. Use constraint to trailing and leading and top and bottom of that ContainerView to UIScrollView. and use constraint for placing child views to viewController.view not to ContainerView to then iOS will find where child views have to be.
Good Tutorial to find out how to use constraint on scrollView
Apple Technical Note
Do Not use tableview in this case, this content is difficult to maintain in a table view, really, use a scrollview, as for how, a simple googling for "swift uiscrollview tutorial"
Tableview is the best solution for this kind of scrolling views but in the screen you have mapview if it updates every moment i.e. updates with current location then it is not recommended to use tableview.
In that case you can use scrollview with custom views add subview changing with parameters.
In one of my app i did same thing using Tableview. And for that tableview i created a custom cell which have such a big height and i added all the images,map,details of user in that. And it work similar to what you want.
If you want help reply to my answer

I am making an app that use table View Controller and static cell.
I want to make first cell don't scrolling while other can. This is a picture of what i am talking about.(Sorry for my bad English)
For example as in this picture, I want to make 9gag tab stay when scroll. If you play instragram you will see that when you scrolling the name of user will stay until you scroll into another one. However I want it to stay not changing when it encounter second cell.
Any suggestion?
Using UITableViewController would not help here. You can use these steps to get what you want:
1. Create a UIViewController.
2. Add UITableView as its subview.
3. Add another UIView as UIViewController's view's subview.
4. Using auto layout constraints, you can put UIView above UITableView
This way, you will get a sticky view at the top.
Ok, not exactly sure what you're after but i'll take a stab.
Firstly, if you want the section to remain in place until a new section of items is present, you just need have a look at sections. This is an automatic feature. You may not see it occur until you have plenty of items in the sections.
UITableView With Multiple Sections
There's plenty of stuff about it & not too hard to implement.
My other guess of what you want:
If you want it to remain static regardless of anything, perhaps you could just create a view and place it above the table view. why does it need to be a part of it if it doesn't change?
I want to add a subview to a UICollectionView in order to make a left panel that scrolls with the collectionview.
Using
[self.collectionView addSubview:myView]
all touches become disabled and I can no longer scroll the view. I've read that adding a subview to a collectionView like this is bad practice.. is this true? Why does it disable touches from reaching the collectionView event when
userInteractionEnabled = NO
I'm trying to do this: imgur link by grabbing the frame position of the first cell in each section, and adding a dot with to myView with the same y value.
Thanks for any help!
Adding subviews using the addSubview: method to a UICollectionView is very bad practice. It can cause a lot of different problems in the normal behaviour of the CollectionView. It can obstruct the views underneath it, capture the touch events, preventing them from reaching the actual scrollView inside the CollectionView, etc. The subviews added using this method will also not scroll as the other elements in the CollectionView do.
The correct way to do what you want is to implement a new type of UICollectionViewCell for the dots, and compute their locations in the prepareForLayout and layoutAttributesForElementsInRect: methods. Basically you'll have either one or two cells in each row. Which ones will have two rows will be determined by you in the methods I've mentioned.
In fact, Apple's docs have a perfect example that's even more complex than what you're trying you achieve. You should check it out from this link.
May I know the purpose of that scroll view ? Because, if you're looking for a subview that displays only a label or image etc., You can use custom collectionview cell instead if I am not wrong... Hope it helps :) :)
I have a UITableViewController that looks like this:

And i want to implement a paging system by using UIScrollView. Now from what i understood UITableView inherits from UIScrollView. Still i have no clue how to proceed to make this happen.
So what i want to be able to do is when the users enters the view i showed on the picture the user can swipe to get to another UITableView with different data of course.
I tried myself using gestures for a while but i learned that i should not use it and use this method instead. I have been trying out this for a while to but i am getting nowhere.
Some guidance or code snippets would be of great help!
I am using storyboards.
Thank you
If you want to page vertically up and down within the table view, set pagingEnabled to YES on it and set its contentSize. That might get to be an issue if you start having rows that don't line up with the contentSize perfectly though.
If you want to page horizontally between different table views, you need to put each table view into a UIScrollView, set it's contentSize to be the width of each of the table views summed together, and set pagingEnabled to yes on it.
I'm new in iOS development. Based on my assumption, Feature page in App Store was created using a combination of UITableView and UICollectionView. But how to do that in theory and code? I know it's a bit vague, because it's quite hard to describe it, but I just need some people to help me explain it.
For this case I will try to use these naming:
1. Top section, it's a view which showing banners of apps, people can swipe it to view another banner.
2. Middle section, views which can be scrolled horizontally. (Best New Apps, Best New Games, etc).
3. Bottom section, starts from Quick Links to the bottom.
Questions:
1. The scroll indicator is starts from the root view's top guide, that's normal, but:
a. When we scroll it up, the bounciness is start from the middle section. How to do that? Is the top section and middle section is a separated view? But how can the scroll indicator is started from the root view's top guide if top and middle section is a separated view? (Separated view means that the views should have different scroll indicator unless it's actually subviews of UIScrollView).
b. When we scroll it down, there is nothing that floating. So it looks like that the whole page is a subview of a single scroll view but the bounciness is starts from the middle section. How to create that bounciness effect while only have one scroll indicator for the whole page?
2. In the middle section, there's a several collection view that has horizontal scroll direction. Is it the best way to create it like that is to use UITableView with cell that has UICollectionView inside it? It looks like it was created that way, but:
a. Is it the most efficient way to do that?
b. Because of the case in my first question is my source of confusion.
3. The bottoms section has a different separator from the middle section. The middle section has indentation while the bottom section doesn't. How can I do that if the case is it's a UITableView?
My whole question is just how to create a layout like that. If you cannot help me by providing me some sample codes that's fine, please just explain me the concept or theory of how to do that.
If the whole answer is just I have to create it using vertical/horizontal UIScrollView from scratch that's fine. I just want to make sure of that since I tried to avoid dealing with creating manual tiling.
OK, I think I finally found my own answer.
First, I need a UIScrollView to be root of the view. Then I set the contentSize to be a specific value.
The top section can be a UIPageController or a horizontal UIScrollView.
The middle section is a UITableView with scrollEnabled to NO and cells are static. The static cells (could also be dynamic cells) will contains UICollectionView. Since the scroll is disable, it will use the scroll from the parent UIScrollView. So that's why I can get the same bouncy effect in the middle section.
The bottom section is just another cell of a UITableView.
Thanks.
This might help you with implementing UICollectionViews in your UITableViewCell: http://ashfurrow.com/blog/putting-a-uicollectionview-in-a-uitableviewcell
To make the first cell "float" in the TableView you could make sure that cell never goes out of screen in scrollViewDidScroll
I need to build a UICollectionView with a UICollectionViewFlowLayout and a very dynamic "header" (for clarity, I'll call it "view A" to avoid mixing it with a true collection view header) but I'm not sure about what can be the best way to do that: collectionViewCell, header or supplementary view?
What I mean by flexible, the bullet point being ordered by decreasing importance:
View A will contain buttons and subviews that need to detect gestures so I must be able to detect actions on subviews of view A.
I need to be able to reload data on the collection view without reloading view A.
I need to be able to update the layout of subviews of view A whenever I want (on viewDidScroll of the collection view delegate for example, update according to contentOffset changes).
If possible, I'd like to be able to change the frame of view A dynamically (I mean without having to invalidate the layout). I would like view A to be sticky at the top and shrink while scrolling until it disappear. Have a look at recently launched "Secret" app to see what I mean (done on UITableView for them). Though I could just scroll without changing the frame and cheat by changing the layout of subviews (see point 3) in order to give the sensation of a sticky header.
What do you think is the best component to do that? Can I use a UICollectionViewCell, a header or a supplementary view? If so which one? If not, do you think of an alternative way I could use to have the same behavior (transparent header and view A behind the collection view? adding view A somewhere else, where, in the view hierarchy?).
Thanks for your help!
Take a look at the UICollectionReusableView class.
You can register your nib on the CollectionView as "SupplementaryView" (registerNib:forSupplementaryViewOfKind:withReuseIdentifier:, use the UICollectionElementKindSectionHeader kind of view)
then you have to implement the collectionView:viewForSupplementaryElementOfKind:atIndexPath: method in your delegate and make sure to return something for the UICollectionElementKindSectionHeader kind.
and finally you have to implement the collectionView:layout:referenceSizeForHeaderInSection: method of your UICollectionViewDelegateFlowLayout to set the size of your header.
Let me know if it help.
