How can i make a view like this. I am done with first portrait mode and confuse to to achieve the landscape mode.? can anybody suggest me how to make the view in landscape mode. I have done portrait mode in AnyHeight AnyWidth format.
Although the question might be a little broad, I'll try to mention a generic answer.
Assuming that your are already familiar with Auto Layout and Size Classes, in Xcode 8, Interface Builder you can change the current view of what are you working on:
By tapping the "View as:" button, you will be able to see the desired device orientation to setup the desired layout via device configuration bar:
For example, Consider the following View:
As yo can see, both of the views have the desired constraints to be displayed in portrait mode, for now, you should add add new constraints for the landscape mode. Make sure to deinstall the constraints for portrait mode:
As you can see, some of the constraints appears faded, which means that they are uninstalled on this size class. You can determine installing the constraint by selecting it and from the attribute inspector, check the desired size class(es):
For more details about how you can achieve this, I would suggest to watch Making Apps Adaptive, Part 1 Session.
Hope this helped.

I am trying to layout user interfaces differently for Portrait & Landscape orientations. The difference comes in the following ways:
I have few UIStackViews. Some of their axis becomes horizontal in landscape but vertical in portrait mode,
The order of buttons in UIStackView may be different in both the modes,
A button which is added to subview1 in landscape needs to be removed & added to subview2 in landscape. subview1 may not be present at all in portrait mode,
Autolayout constraints are different in both the modes.
I started with vary for traits in XCode but it seems to have limitations. I am manually switching constraints in the code on observing trait collection changes (viewWillTransition:...) but it seems clumsy. Is there a better way or the best way would be to have duplicate sets of controls for both the modes and hide the ones not needed in landscape/portrait modes?
The interface builder is really powerful if you use it right, I'm not completely sure what you're trying to do, it'd be useful if you share some screenshots at least. I'm assuming that you're every subview of the UIStackView is a button, or it contains a button, in that case what I'd do is:
Having 2 different UIStackView, one for landscape and the other for portrait.
Add variants to the installed interface builder property for traits. So only one of the two UIStackView will be installed at a time.
For every UIButton add the event, connect it to the respective IBAction or selector. This will work even if there're 2 buttons that do the same.
So regarding your issues:
The axis itself wont change, but this will work because there're 2 version of the UIStackView.
You can choose to arrange the button on each UIStackView.
Just add the buttons wherever you want on each UIStackView.
Set the constraints as you want depending on which UIStackView you're working on.
An I missing something? please update your question with more information so people can help you in a better way.
What I have done is to observe the UIDevice.orientationDidChangeNotification and update the necessarily constraints to achieve different layouts, as you have already implemented. And I think this is the better way to solve the problem and never trying or even thinking to create different views for each orientation 🙅🏿♂️.
Attending the conditions:
The first condition only needs to set the axis property accordingly.
The order of the arrangedSubviews is part of the design, and therefore, its up to the developer to rearranged them manually if he/she has to.
In this part what I would do is what you have said: to removeFromSuperview() the button and addSubview(view:) from one subview to another.
This is made automatically, as long as we activate the constraints for one orientation and deactivate the other ones, the system update the UI without any problem.
The most important thing is to make sure that when removing subviews, any constraint attached to it is removed, or the app will crash.
I need a button to be installed in portrait orientation while another button is uninstalled in portrait orientation (any width, any height), while the reverse should occur in landscape orientation (any width, compact height). One of these buttons is part of a UIStackView and the other is part of a UIView.
When in portrait the button in the UIStackView should be installed, but the button inside the UIView should be uninstalled, with the reverse occurring as I mentioned earlier in landscape. Currently I'm checking the userInterfaceIdiom in my view controller for the storyboard, but would like to rely entirely on Interface Builder if possible.
When removing my code (that actually makes it behave correctly), and simply relying on Interface Builder for installing/uninstalling the buttons based on size class, the button installed for landscape orientation always lays out correctly, but when rotating back to portrait, the other button that should now be installed is completely misplaced, out of it's original UIStackView, and that UIStackView that it should stay in, but hasn't, is now expanded to fill in the missing space where that button should have been. When this is happening, there are no warnings or errors from UIKit in the log, and my storyboard shows no conflicts. I'm thoroughly stumped!
At first glance this seems like an easy solution. Simply check/uncheck the install box for size classes of a UI element. Although, even after reading Apple docs and tutorials this is proving to be more difficult and obscure than I expected.
To clarify, I do not have constraints set for the button installed for portrait orientation since it is inside a UIStackView. On the other hand, I do have a few constraints set for the landscape orientation button. Although, the button in the UIStackView is the only one giving me trouble.
The view debugger is not working either in Xcode 7, and I'm receiving the error: warning: could not load any Objective-C class information from the dyld shared cache. This will significantly reduce the quality of type information available. when attempting to use it.
I believe this may be a bug and related to this post: UIStackView properties according to size classes
Your help is greatly appreciated! Thanks.
If you want a component to appear just in a specific size class this is what you do:
Add the constraints to you component using the size class you want it to appear in (wCompact hRegular for all iPhone in portrait and wAny hCompact for all iPhones in landscape). Next make sure that only that size class is ticked in the Attribute Inspector.
Leaving Installed ticked will make the component appear in any size class. You can change the size class of a view controller in a storyboard file by clicking on the option in the center bottom of the screen (see the blue bar at the bottom of the screen, where it says wAny hCompact in the image above).
I hope this helps!
UPDATE
Make sure that the constraints of the components are also set for the correct size class.
From the Document Outline select the constraints of the component and check the size class of the constraint in the Size Inspector. Usually, when you add constraints to a component with a specific Size Class selected in the story board, the constraints will automatically be added for that size class.
I'm trying to use view controller that I decided to use auto layout for. Before I used auto layout, the view showed normally like how I intended it to during runtime. But I decided to switch to auto layout (because after all, bigger iPhones are coming), and even after setting it up, getting no issues at all, and seeing that the app scaled well to the iPhone size in IB; I still have a blank screen. To prove it, here are pictures:
So why is this happening? I added the constraints in the square view, and it gracefully scaled to the iPhone view in Interface Builder. If you also look at the sidebar, the alerts for auto layout errors are not present. And IB is rendering everything. But why is the simulator blank?
And yes, I connected all the elements to be code correctly. I verified. And yes, I have code that puts text in a label. Here it is, in the 'viewDidLoad()' method:
override func viewDidLoad() {
super.viewDidLoad()
self.titleLabel.text = "Hello, World!"
}
And I will reemphasise: the app worked before I did auto layout. For this build, I deleted all the elements, relocated them, reconnected them, and added tweaked the view with auto layout unit IB rendered it correctly. But I'm getting different results here.
Please help me. Oh, and sorry for the massive images, I can't figure out how to shrink them.
EDIT: I've gone through and used the view debugger, and tried to capture the view hierarchy to look for clipping or occlusion. Funny enough, the view debugger shows the content properly, and there wasn't any clipping or occlusion that I saw. When I tried to show frames in the simulator though, it didn't show anything. I'm starting to think that this is a simulator bug. Currently, I'm using Xcode 6 beta 6.
I recreated the issue by adding a collection view to a standard view controller and this seems to be the problem:
Having Xcode add suggested constraints gives you this, which causes the view to not show up.
It is aligning the view's left and right to the layout guides (which doesn't seem to be right)
You will have to manually add spacing constraints to your view.
This is what you want:
Try turning on the assistant editor and use Preview while tweaking your constraints.
(source: mattknott.com)
Do your Editing in "wAny hAny For All Layouts Base values" mode. then you will not see blank screen while testing on different devices.
Mode selection can be one from bottom bar.
Good Luck
I have an information app. I chose to use text views, because I can simply copy information and paste it into a view.
I want the text view to show up properly on the top of the view controller in both portrait mode and landscape mode. The view shows up properly in portrait mode, but some text is cut off when I rotate the iPad to landscape mode.
I should mention I'm using a storyboard. Also, for the benefit of others (myself included,) if there is any code involved, please mention where the code belongs.
Here's your solution: You must simply find out the right configuration of autosizing. That's all. Try it out, by building your project after changing. This should help you.
If you are adding the TextView programmatcially then you just need to set the appropiate auto resizing masks like: textView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin, but you might need to play around with the different options to get what you want based on the location of the textview and how you want it to be manipulated when the device is rotated.
I want to minimize the amount of code I have to write, and use storyboards in xcode to specify the way the view should appear when in both portrait and landscape views.
What is the best/recommended way to do this that minimizes code? I've done some research, but am having trouble finding a simple solution..is it necessary to do some conditional segues, and re-hook up everything in my landscape view, or is there a simpler solution? Thanks!
Generally you define the autoResizingMask (or go to the size inspector in Interface Builder, as shown below) so that the controls will move or resize as the screen size changes. If you do that, you'll generally have pretty decent support for both landscape and portrait. You'll only have to do programmatic changes to the controls' frames if you do some fairly significant changes on orientation changes (e.g. you want to shuffle the various controls around so that they are in very different positions with respect to each other when you change orientation or you want to load very different UIImages). But 90% of the time, autoresizing settings can handle simple moving/resizing/recentering of controls for you:
