Using Multiple Size Classes - ios

So I've built this app and the layout is so that it requires me to use two size classes:
1) wCompact hAny
2) wCompact hRegular
All the alignments and all that is great and this should be giving a smooth, consistent display across all devices. However, it seems that the 2nd size class is overriding the 1st one in all situations. I only want number 2 to fire up on 6+, but it's doing so on 6 and 5s as well.
How can I fix this? It's really holding me up on here.
Thanks!

The First size classes you are using is for iPhone 4,iPhone5s and iPhone 6 for Portrait and landscape .
The Second size classes you are using is for all iPhone devices in portrait mode only.which means obviously they are overriding each other.
Use only second layout for all iPhone devices in portrait mode. and if you want to use size classes for landscape mode wAny hCompact.

Disable landscape orientation for iPhone only using size classes

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.

Xcode 7 to 8: Size Classes

I have developed an app with Xcode 7 and I placed all my views for all iPhones in portrait. Now using Xcode 8 I want update the constraints for supporting iPads in portrait. How I am supposed to to that? Copy/Paste views and start from scratch? I can't see any other solution.
PS. Note that views for iPhone 7 Plus to iPhone 4S appears fine.
No need of copying the views. The Xcode SizeClasses aids you in designing the app for various devices.
I suppose you may have used the Any Width Any Height (wAny hAny) or the Compact Width Regular Height (wC hR) to design the portrait orientation screens. Now use the Regular Width Regular Height (wR hR) size class to design the iPad screens. Size classes will automatically switch sensing the device rather than programatically selecting one among the two storyBoards designed for iPhones and iPads.
Select the wR-hR size class. Select your view in the Document Outlinein the storyBoard. In the Attribute Inspector install the view for the current size class (wR hR). the view will appear in the storyboard scene. Set the suitable constraints and you are good to go.
PS: Of course you must set the constraints again unless you have designed the iPhone screens in wAny hAny size class. If so that works in iPads too and you needn't work on any other size class.

Supporting all iphone sizes

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

Autolayout in iPhone Portrait Mode

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:

Xcode Layout constraints: selecting divisions

I want to have two different layouts. The first layout must be applied to iPhone-3.5inch, and the second one to all the other device sizes. However, the layout I set for the compact width/compact height does not seem to take over the other layout even when I test with an iPhone-3.5inch. How can I make the first one be applied to a small device, while the other to the bigger ones?
according to documentation compact width/compact height is size class for All iPhone models except iPhone 6Plus In landscape mode.
If you want to know whether the device is with 3.5inch screen you must do it in code.
