I am working on a project to get custom news feeds from Bing news. I created a custom table view cell and populated various UI items in it. But I am having a hard time to make it occupy the entire screen, it starts from extreme left and ends on the right, leaving large gap from the right margin as show in the image. Can anyone help me out, how to correctly fix it with a detailed explanation of how constraints work in Table views and Tableview cells.
Here' what it looks like in the simulator
Remove previous constraints and add constraint to your UITableView like as shown in below image.
So you UITableView will have 0 margin from edges.
Create a UITableViewController. Just drag drop a TableViewCell into it. Add identifier for that cell and use it. By default it will occupy the whole screen.
In your case I guess you might have added constraints to UITableView. Here what you should do is pin your UITableView to Top,Bottom,Right & Left or make UITableView's width equal to SuperView.

I’m trying to sync two collection views proportionally for navigation. One of the collection views is menu-like and is at the top, and the second is a larger one below. What I would like is for the top collection view to scroll a distance of the width of one cell (the cells are dynamically sized) when the user scrolls the bottom collection view a distance of the main screen’s width. The closest thing I've seen to this effect would be iOS: Custom top segmented control works as expected only when using debugger. What I would like to change is to have the left most cell in the top menu always selected. In addition, when the user scrolls the bottom collection view the width of the screen, a new cell should Replace the left-most cell in the upper menu and be selected. Any help in Swift would be especially appreciated, but ObjC answers are also welcome.
I am looking for how to, in Swift and Interface Builder, create a UITableView in Xcode where the table has a set width (example: padding to left and right edges of superview might be 8). In the table, I want cells to go across the first row. When a new cell can no longer fit in the first row I want it to go to the second row. When a new cell can no longer fit on the second row, I want it to go to the third row, etc. I only want the table to scroll vertically.
If anyone can point me to examples or documentation on this I would greatly appreciate it.
You are looking for UICollectionView.

I'm having trouble setting a layout for my iOS app. The entire app is shifted right for some reason as you can see by the label and buttons which are in the middle of the scroll view.
I also can't seem to display the entire table. In the screen shot below "another Item" is supposed to have a checkmark and it is only visible if I shift the table in Main.storyboard far to the left where the actual label for the cell item is half visible.
I have a scroll view inside of the view controller and then a label and three buttons as well as a table view with table view cells.
Thanks to Lucas for the answer
Are you using Auto Layout with that storyboard? Looks like you might not have set your constraints up properly. You might also want to take a look at Xcode's new View Debugging functionality.
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 have a tableview that has a large number of fairly tall dynamic cells. I've tried creating the prototypes for these but I've run out of height room in the view.
I can't seem to extend the height of the table view, (or the view it's in). I also can't create the tableview outside the viewController, give it a larger height, and just link to it.
Suggestions? I know I can create the cells programmatically or from a separate nib, but I'd really like to do it via storyboard.
thanks,
Just figured this out myself. Try this:
Double-click the table almost anywhere except where there's an existing control. You can also double-click on the outer edge of the table.
Note that the table view will show a highlighted section that aligns with the cell you've clicked. You've entered some sort of selection mode.
Now use the mouse to scroll up or down. The cells will shift up or down as if you were running the app.
