I have to design an app for all iPhone size portrait mode only. I am using storyboard and setting constraints using storyboard itself. What makes me confuse is Size Classes. Since my requirement is iPhone portrait only, I am using Size Class compact Width|regular Height. My question is can I disable the Size Classes cause working only for iPhone portrait mode. If yes, then can I design with Size Classes disabled for all iPhone size. What is the right approach?
Intuitively, prior to size classes, storyboard UI was designed by doing a separate interface for each iPhone size. Since the advent of a broad range of device sizes, size classes have been incorporated. Considering that your app may have to run on older devices, there is still a difference in size between iPhones in portrait mode. Because of this, you would likely have to make a separate interface for each orientation, which I have not tried. I believe the correct approach would be to simply design for the size class that you selected.
If you are only making your application for iPhone portrait not necessary to use the size classes. You just have to set proper contract which are in the size indicator.
It's my opinion for it.
If you are developing for iPad and iPhone size class is the best option.
Size classes deal with the problem of multiple orientations(portrait and landscape) and different devices(iPhone and iPad). You cannot differentiate between two different screen sizes for iPhone using a size class. Similarly you cannot differentiate between iPad mini(portrait) and iPad Air(portrait) on behalf of size classes.
All iPhones in portrait has the same size class behavior i.e Compact(width) | Regular(height), be it 3.5", 4.0", 4.7" or 5.5". Similarly all iPhones in landscape has Regular(width) | Compact(height) size class. Size classes aren't the solution to the problem you are facing.
In order to handle multiple screen sizes for iPhone in portrait, the best bet would be to make use of autolayouts. Pin your views with the boundaries so that they will get stretched or contracted on different screens. Similarly bind your labels with the boundaries of their superview so that they will grow too. Also you can make use of aspect-ratio constraint that will allow to grow your view and images relative to the aspect-ratio of the element rather than increasing them horizontally to end up with an elongated look.
If you are new to autolayouts I will highly recommend watching the following sessions from WWDC2012:

So all phones have compact width/regular height in portrait. Plus phones have regular width/compact height in landscape while others have compact width/compact height.
So the only in LANDSCAPE orientation you can distinguish a plus model phone.
Question
Is there a way to distinguish a plus model phone in portrait orientation?
without checking for:
Screen resolution
Screen scale
Device strings
NOTE:
Checking for screen resolution/scale, device strings are plausible, however trying to stay away from those. For example, Apple had to put Contact Icons for Favorites for iPhone Plus in Portrait. So there has to be a formal way to do this?
You are getting it wrong. The main purpose to make the adaptive layout is it can adapt to any screen size irrespective of device.
You should not think about these devices screen size while making layouts. You should be thinking of size classes.
If your layout can work in above size classes than it should work in respective phones. Also if you are looking for orientation but your app support the multitasking than your layout might not work with that.
Ideally, Your app should have layout that can work in any screen size because apple is releasing new devices with different screen sizes so your app should be compatible and work in every layout.
But that is ideal world. You can handle most of your layout with size classes. In some cases you need to handle the special scenarios.
I am using adaptive layout with size classes (iOS10).
For an iPad I want to support portrait & landscape views, but for iPhone I only want to support portrait. I don't want to rotate screen for compact height.
iPad is all fine and I have set-up the iPhone views using size classes, so I am thinking I need to somehow detect what size class will be transitioned to and disable rotation if it would go to compact height.
I can see a method called traitCollectionDidChange, but not sure if this is the correct time in the lifecycle to detect this.
There are a few related questions, but I don't see anything that covers this specific scenario.
I'm trying to create a iOS app, but I'm stuck on the layout.
I created the home view, but now I see that it's not shown in the right way in the 4S simulator.
I tried with size classes, but it looks like 4S and 6, for example, are in the same size class, and so I can't set a different dimension for views.
My goal is to support all devices, also iPads. Can someone please tell me how to do it?
Size classes mostly used for separation between ipad, apple watch and landscape modes.In potrait mode iphone 4 to iphone 6 all phone device sizes are in same class(regular height and compact width).Autolayout has many different constraints to help you to fit interfaces in same class.You should consider horizontaly/verticaly align, equal width and aspect ratio constraints.They are so flexible for smaller size changes and help you to design adaptive layout.
You should use "Reset to Suggested Constraints" for all views in your View controller. You can also check the simulated metrics for all devices without compiling the the code.
For 4s and 6 by default the size is Inferred. You should try resetting the constraints to check this for iPad as well.
I am just sharing an idea
Option1:
I think You can try adaptive Layouts and in file inspector->simulated Metrics->size-> Inferred. It works in all devices it supports both landscape and Portrait.
Option2: Go for Visual layouts they are easy to understand and they work perfect in all modes of Portrait.
I am think that you use code Instead design in main.storyboard !
for ex: create button with code
(and use Ratio in your code)
by this way i create small app for iPhone & iPad

How can I make different layouts for different orientations on ios?
I try to make an layout in landscape to show 6 picture's in 2 rows.
But in portrait I only will show 4 pictures in 2 rows.
I already have 2 different storyboard for iPad and iPhone.
Can I do this over constrains?
Can I do this with different storyboards like in android?pain
iOS has something called Size Classes. You can use a size class to target a specific device and/or orientation. You can choose the appropriate size class at the bottom of interface builder (wAny hAny) and layout your view accordingly.

Adding on to #Nitesh's answer: Correct me if I am wrong, I am not very well versed in iOS development as well. I read that it is almost always recommended to use Size Classes while only using one storyboard for all targeted devices. It makes handling issues like screen sizes and orientation much more managable.
In your case, may I suggest using UICollectionView to achieve that effect? It rearranges your tiles based on how much width you have and it supports orientation quite well.
We all are going to update our apps to iphone 6 and iphone 6 plus. That means we need to support 4 sizes.
1.) 3.5
2.) 4
3.) 4.7
4.) 5.5
Can we support all these screen sizes with single xib or storyboard ? also please share your views on how we can update our existing apps for iphone 6 and iphone 6 plus.
Yes. See Apple's iOS8 documentation specifically, size classes:
iOS 8 makes dealing with screen size and orientation much more versatile. It is easier than ever to create a single interface for your app that works well on both iPad and iPhone, adjusting to orientation changes and different screen sizes as needed. Design apps with a common interface and then customize them for different size classes. Adapt your user interface to the strengths of each form factor. You no longer need to create a specific iPad storyboard; instead target the appropriate size classes and tune your interface for the best experience.
There are two types of size classes in iOS 8: regular and compact. A regular size class denotes either a large amount of screen space, such as on an iPad, or a commonly adopted paradigm that provides the illusion of a large amount of screen space, such as scrolling on an iPhone. Every device is defined by a size class, both vertically and horizontally.
There is also a very good tutorial video on the WWDC site.
In order to stop your iPhone 6/6+ app being scaled, add a launch image of the correct size or better, use a launch storyboard.
From there you should use AutoLayout and avoid hard coding to screen sizes. In the long run it'll be a lot less effort and less error prone.
In existing projects you can use autoresizing or auto layout of xib files.. that support all 4 devices.
I have implement my projects using autoresizing to support all devices.
