How to make cell doesn't scroll along with other cell? - ios

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?

How to achieve a (almost) full view uitableview that can scroll past the last cell and show further elements in iOS

I have attached the below image because it describes my problem better than words:
So basically, I need the Title/Subtitles part at the top to always be static, after that a dynamic UITableView which will have a lot of cells (mostly will fill the rest of the screen), and then after that a few additional elements such as a Map View and etc.
I'm using storyboards/xibs for this so it was also an issue of how to constraint everything in the designer properly. Would a stack or scroll view be appropriate for this?
I think you can take two paths to achieve this.
The first is to create a custom cell containing the map and another containing the "Paragraph of text" thing.
Then you only need to push the cells at the end of the original data source.
Keep in mind that you need to add this cells to the RowsInSection function.
The other way is add a custom footer view to the tableView.
You can create a custom UIView containing the map an other info and then tell the table to take the custom view as footer:
tableView.tableFooterView = customView

How to setup a UIScrollView to arrange content dynamically?

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.

Using paging in UITableViewController

I have a UITableViewController that looks like this:
https://www.dropbox.com/s/dy6o55qa8squi9f/Screen%20Shot%202015-04-14%20at%2000.13.29.png?dl=0
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.

How to create a layout like Featured page in App Store?

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

tableview controller, embedded tableview, or something else for this interface?

I'm trying to figure out what kind of iOS user interface element(s) I should be using to create this interface:
At the bottom of this view, there is a list of items. This list of items can be arbitrarily long. As such, and because of the standard detail disclosure indicator and so on, it makes sense that this is a tableview.
However, the items at the top are not tableview cells. The obvious answer then, is to simply place a tableview on the view, i.e. an embedded tableview. But this leads to another obvious issue, which is that this entire view should be scrollable - there will be a button for "Add Item" underneath the list of items which you will need to be able to scroll to, and the interface will be crappy if the whole view doesn't scroll.
So, I could make it so the tableview is not scrollable, and is just as tall as it needs to be to include as many items as it needs to. Then, the entire view is embedded in a scrollview, and scrolls properly. My concern with this relates to memory management, if I do this, I don't think I'll be taking advantage of the dynamic cell creation that is inherently part of a scrollable tableview, and will instead have dozens or even hundreds of cells instantiated when the view loads.
Another alternative would be to make the entire interface a tableview, with the top portions, and the bottom button, implemented as custom tableview cells that are different from the cells that show items. In the past, however, I've found that this is a pain-in-the-ass too, but perhaps it's a pain I must endure.
In general, I feel like I'm missing an obvious approach here, since this seems like it ought to be extremely simple to implement, but I'm currently at a loss. Help is appreciated!
jjv360 mentioned it correctly, this should be 1 tableview with sections and custom cells. The different look comes from nice images.
It's all a tableview with a single cell type, and 4 sections.
The cell has an optional image, a label and the optional disclosure indicator. If those don't exist, the label expands to encompass the full space.
It's very easy to do, quite standard.
