I'm working on a project were I use mostly UITableViews. The user enters data and the App gives the result of a calculation. I have two buttons: "Calculate" and "Reset". I want to add a subview containing these two buttons and have them displayed at the bottom of the screen. By Storyboards, I can add the subview, but it sticks to the button of the UITableView, not the screen.
Any idea on how to accomplish that? Should I mess with the constrains between the subview with the buttons and self.tableview.superview ?
Any help is appreciated!
You can use a standard UIViewController instead of a UITableViewController, and add a UITableView to your view controller. You can then place subviews at will.
Do not forget to connect datasource and delegate of your tableview.

I'm building my application with Swift and I want to set up TableView and CollectionView in the same ViewController.
The only answer I founded is to setup my CollectionView in the TableViewCell of the TableView.
I did it but it scrolls separately.
The solution I found is to disable CollectionView scrolling and then configure CollectionView's height constraint programmatically by summing heights of the cells. It isn't perfect at all because cells become non reusable (250+).
I'm in desperation because I have seen this setup in many other apps and I think that answer is so simple but I can not find it anywhere.
Can anyone please help me? Thank you a lot!
Another option is to set it up as a single collection view with two sections, one that looks and lays out as a tableview and the other that has the more collection view appearance.
Or set it up as a single table view with two sections, one of which displays two side-by-side images per line (this is the old school way of creating this layout.)
Lots of ways to go about it, depending on what you want to play with and what you want to learn :)
You can put a UITableView and UICollectionView inside a UIViewController, and implement UITableViewDelegate, UITableViewDataSource and UICollectionViewDataSource.
Keys:
Use AutoLayout to make sure tableView has only two rows, and
collectionView takes the rest of area.
Make sure tableView.scrollEnabled = false

Set up a blank ViewController. Then place two ContainmentViewControllers inside of the ViewController. Size them however you want based on how much screen you want to the be tableview and how much you want to be collectionview. Then create segues from each containmentViewController to your tableviewcontroller and collectionviewcontroller using embed. This will allow both to be on screen at once and scroll separately.
If you do not need to use a TableViewController and can get away with just a tableview you can also just place one containmentviewcontroller below your tableview and create the embed segue to your collectionviewcontroller.
I am trying to create a UI just like Facebook's comment screen on mobile.
I got a UITableViewController on my storyboard. I need to insert a view docked to the bottom of the screen to place a text field. Since the tableview is taking the full screen, I can't do it on storyboard and I think I need to do it programmatically but how? Should I modify the constraints that stretch the tableview to the edges and insert the views or what?
Thanks.
You can always add table view to normal UIViewController and below it add another view.
According to the answer at UITableView, make footer stay at bottom of screen?, which I verify:
In order to have a footer that stays put at the bottom of the screen,
and doesn't scroll with the table, then you can't use a table view
footer. You can't even use a UITableViewController, you'll need to
implement your view controller as a UIViewController. Then you add
your own table view as a subview. You'll also need to add your footer
as a subview of the view controller's view, not the table view. Make
sure you size the table view so its bottom is at the top of the footer
view.
but the problem is that my UITextField, inside my footer, is being hidden by the keyboard when user tries to type. So how do I keep the keyboard from hiding the UITextField? Throughout the app, I have been using TPKeyboardAvoiding. But in this case, where a UIScrollView/TPKeyboardAvoidingScrollView contains a UITableView and a UIView in vertical order, it does not work. I generally like TPKeyboardAvoiding because it’s so quick and easy. Any ideas how I might fix this issue?
The instruction that you quote is telling you to use a UIViewController, add a UITableView as a subview, then add a UITextField as a subview of the UIViewController NOT as a subview of the UITableView.
Let me draw it out for you:
Step 1:
Add a UITableView to your view controller
Step 2:
Add your UITextField subview (you can embed the UITextField in a UIView container if you like) as a subview of your UIViewController's view NOT your UITableView footer.
Step 3:
If depending on if your using frames or autolayout, you adjust the frame or autolayout constraint constant values for your UITextField subview when user tap on the text field.
Step 4:
Finally, the keyboard appears and the UITextField doesn't get obscured by the keyboard.
Just make sure your UITableView doesn't initialize it's own automatic scrolling for keyboard appearing. If you use UITableViewController then just subclass it and make sure you don't call it's viewWillAppear:. I didn't investigate which exactly method you should block without using UITableViewController, so, you should find out this yourself or somebody else would help.
I did similar in my own project where I wanted to have own scrolling of table view for keyboard appearing.
Check out this image below, this is what I'm trying to accomplish, but I ran into some problems. The first approach I made was to have an imageView (blue square) and 2 separate tableViews within a scrollView. Each tableViewCell would have textFields inside them. The first issue was when the keyboard came into the view, I would move the view up to make sure the bottom textFields were not covered up. I then wanted to be able to scroll up and down so I could still see the top textFields as well. This didn't work because when I nested the tableView inside the scrollView, The scrollView wouldn't scroll. I was also having a problem with setting the firstResponder to pass from textField to textField on the second table only.
I then decided it would be better to create 1 tableView, and add a custom cell to hold my imageView and two textFields. My question is, is it possible to create that custom cell that will hold my imageView and two textFields? would this be a better approach?
Thanks
Wow, I think your can do it easily by UITableView. All you need to do is customising UITableViewCell.
This is possible using subviews. However, why you aren't considering UIViewController or UIScrollViewController for this design?
I would like to add a UISegmentController in the top of my UITableViewController, just like in the AppStore.
I have tried googleing this but either I am search for the wrong things, or too view have written about this.
How can I do this, keeping it in the top with a different design than the UINavigationBar.
For style add segmentCont.segmentedControlStyle=7; which is same as the picture style.
It may not be a UITableViewController. It might be just a UIViewController with a segment control at the top of the XIB and a tableview placed underneath the segment control. That way, you could scroll the table view without scrolling the segment control.
I believe that is a custom header cell for the tableview. You should start by created a custom header with your segmented control inside that.
I think that's a ToolBar with UISegmentedControl or just UISegmentedControl and UITableView under it. You can place them (UISegmentedControl + UITableViewController) on UIScrollView and disable scroll for UITableView. You should make appropriate contentSize for your scrollview.
