I'm trying to set up a layout where a Map is placed on top of the SceneView. When the app builds, the set up flashes for a second, and then the SceneView takes up the whole screen, completely hiding the other two views.
After moving the SceneView on the left hand menu and moving it back, the text started appearing but not the black background.
(I've got constraints set for the Scene View to take up the whole screen, and some constraints (right and bottom) on the Map too.
Why is it not working?
EDIT: It started working after I deleted the view and added it back in, but not sure why. #El Tomato says SceneViews always overlaps other views. Is this true (i.e. by accidentally getting it to work, am I utilizing a bug)?
It is doable. I'm doing it currently with an app I am using, but the difference is that I didn't set up the ARSceneView in the Interface builder, but I added it to fit the whole screen programmatically. I have some buttons that were added through the interface builder, and I added a label with a background now just to make sure it works similarly to how you want it.
I will post some images:
Here i simply have the view controller with some (bad looking buttons) in the stack View as well as the label with a red background. The ARSceneView is added in the my ViewDidAppear function and takes up the whole frame.
This picture is from the screen while the app is executing (Debugging the UI). As you can see, the Label with the background as well as the buttons I've added all show.
I also have 2 buttons that are showing as well (the white and red circle) and these were added programmatically and were brought to the front.
My suggestion is to try and add the ARSceneView programmatically, maybe it doesn't work otherwise. Or you can try to outlet all your views and bring the Map View and the Label to the front using bringSubviewToFront.

In Android, on the click of a button I get a screen coming up (the one on the left with just the First Name and Last Name) and on click of the more button the other fields are also displayed (the image on the right).
I tried to achieve this by loading another view on the click of the button, but this shows a view completely filling the screen and not like the one in the image with limited height and the background view being greyed out.
Also to get a screen like the one on the left I made their height constraints equal to 0, but though it showed just 2 textfields, the screen filled the whole screen and not like the one on the left.
Any idea as to how this can be achieved?
To show custom transition while presenting a controller i.e.
your first requirement - a view completely filling the screen & not like the one in the image with limited height and the background view being greyed out.
you can use UIViewControllerAnimatedTransitioning.
I have created a sample here:

I'm using StoryBoards and have a PageViewController for my app tutorial screens.
All viewcontroller's on the storyboard are basically the same, except for a different image of course. When it's running... the first view shows the image anchored to the bottom instead of centering in the view.
As soon as I start sliding to the left, it jumps up to where it should be. All other subsequent views are working great. The second screen grab shows what happens after I start sliding to the next screen.
I'm stumped, I've never seen this before.
Any ideas?
Please check automaticallyAdjustsScrollViewInsets is set to false in your container.
I have storyboard where I have background set and on a top of a background I have weather information showing up. Even if my "weatherInfo" view is set to be on top it is still not showing up. I've added random values (labels and images are not loaded dynamically) it is still not showing up. Here is my settings:
Try this :
Press ctrl + clic & drag from this view to its superview (Named View in your case). You should see a blue arrow
When you release your click, hold shift and add : Center horizontally & center vertically (don't forget to click add constraints at the bottom of the pop up)
Run your app and you should see your view
Finally, try other constraints to get familiar with Autolayout !
Good luck !
Your background might be loading in after your Weather Info view. I'm going to assume that the Background is set to match the superview. Try flipping the order of the views. Have the WeatherView come after the Background.
Please ensure that you have gave the bottom constraint w.r.t the view.
Else the view wouldn't show up
I am learning iphone app development and I am using swift. I took the lynda tutorial and I have created a very basic UI which is View Controller > View .
In the View I added a segmented control, two buttons(horizontal, facing each other), three labels, one textarea and two other buttons(horizontal, facing each other).
So I have these UIcomponents arranged vertically and I used 'Reset to suggested constraints' and made all the buttons equal width and equal height and everything is fine in potrait mode but as soon as I go to landscape mode the last two buttons disappear, if I add a constraint from bottom edges the whole UI gets messed up i.e. only one label and part of an upper button appears.
What should I do to make all the UI components visible both in potrait and landscape mode?
There are many ways to go about this. I've set up a github project to show you one way to achieve it.
Short resume of what I did manually without the help of the Interface Builder:
I've pinned the segmented control to the left, top and right of the parent view
The red button below has a vertical constraint to the segmented control and a leading constraint to the parent view. It also als a horizontal space constraint to the green button
The green button has a trailing constraint to the parent view, top aligned to the red button and widths set to equal to the red button.
This setup ensures, that the segmented control is responsible for specifying the distance to the top of the parent view and the red button specifies the width of itself and the green button (test it, by changing the value of the horizontal space constraint)
I've turned the same principle upside down. So the views in the bottom are always pinned to the bottom. But as I said, there are many ways to achieve this. You could also create 3 container views for the elements in the top, center and bottom and pin those to the top, center and bottom.
The running app looks like this:
If you would like to display your content differently in landscape mode, it is possible (and most likely preferable) to create an alternate landscape interface.
Quoting the Apple developer's page on the subject:
"To support an alternate landscape interface, you must do the following:
Implement two view controller objects. One to present a portrait-only
interface, and the other to present a landscape-only interface.
Register for the UIDeviceOrientationDidChangeNotification notification.
In your handler method, present or dismiss the alternate view controller based on the current device orientation."
For more information about this, check out this apple developer page and scroll down to "creating an alternate landscape interface".

In my iOS application storyboard i have a few view controllers which contain one or more TextViews. Now, on almost everything i do within those views, like adding another button, or resizing a text box, those Text Views 'jump' back to the upper left corner and at the same time they get resized to 0,0.
Is this a bug, or can i do something about it?
I'm using Xcode 6.1
