Would someone be so kind telling me how would you set a constrain (using size classes) for a view to be right above the keyboard (without the predictive part) on iP6 and iP6+ like on the photo below?
May I have a sample project?
Thank you
Either add the constraints in programmatically based on the keyboard size, or make separate interface files for every screen size with a fixed constraint based on a known size for the keyboard for that screen.
Below is a link to a chat application that works from the same premise. When the keyboard is active elements are pushed up so they aren't hidden by it.

The application is in Objective C and pretty easy to transfer that section of the app, I've used this myself.

I need to decrease the height of the keyboard programatically. Is there any way I can do it? I have found that we can reduce height, using keyboard extensions but I tried and it doesn't work for me.
Is there any way I can do this?
Edit: But i can see small keyboards in some of the apps . How do they acheive it.
Thanks in advance.
You cannot modify the frame or the look of the keyboard, since it works kind of like an overlay over your app and it's not a direct subview in the window where your app lives.
You can create a custom keyboard for this approach, but remember to follow the iOS Human Interface Guidelines.
You can also create a custom view that provides input (for e.g. a bunch UIButtons that append a letter to a UITextView if you press them).
I'm new to programming and I'm trying to work with Xcode. I have no experience. I'm trying to make an app with Xcode. I'm done with the code, the only issue i have is with the storyboard constraints. I need some one who can help me to set them up.
So, i have 28 buttons as you can see in the picture, I want to keep the size of 65x65 pixels. that means that the distance between them should vary in different device sizes(4inch, 4.7inch and 5.5inch). i also should mention that i want it to be only in portrait view and only for iPhone.i hope someone can help because I'm to noob for this, I've searched a lot on the internet but I'm not able to do it.
UIStackView (iOS 9+)
UIStackView was introduced in iOS 9, which is very useful in your case.
Edit: Before getting started, make sure to have size classes to be w Any, h Any, this will make thing easier.
To use this, search UIStackView in your utility panel.
Drag an drop a Vertical Stack View on the view of your view controller and set the constraints so it spans the whole screen.
Select the stack view we just placed and set the distribution to Fill Equally.
Drag and drop a Horizontal Stack View onto the vertical one.
Select the horizontal one and set the distribution to Fill Equally.
Place your buttons in the Horizontal Stack View.
Copy and paste the horizontal stack view multiple times based on number of rows you want.
That's it.
You can control the buttons' background images to make it smaller (65px), or you can place a view as its' parent then align horizontally/vertically to place it to the center, like this:
Orientation
If you'd like to lock the orientation throughout the app, go to the settings of your project.
Sample project
I made a sample project for this question, you can check it out here: https://github.com/cyhsutw/UIStackView-example
I am designing a simple user interface for an app using Xcode and Auto Layout. I have a view controller with three basic outlets: a static image view, a label and a button. You can see it in the picture shown below.
As you can see, I'd like to have the image view horizontally and vertically centered in the view controller, the label just below it and the button somewhere in between the label and the Bottom Layout Guide.
The problem is that I am experiencing some appearance problem with the iPhone 6 I am using for testing. The interface items are not nicely centered as they are supposed to be, as you can see from this screenshot.
I am not asking for the solution to this problem, though. I would rather know whether there are best practices to design a good user interface. For example, is there some way to temporarily hide the label and the button from the view controller to focus only on the debugging of the image view without having to remove and redesign them again?
Select the label you want to hide,then uncheck the checkbox installed
You can simply set its alpha to zero .
I am starting a new project which should be working on every iOS device size possible.
The project is rather simple. The main view will be a scroll view and it will hold a '+' button (where it says 'button' in the image) in the top right corner. (It does not really matter, I'm just trying to give the general idea of what I'm trying to understand and implement.)
A small example:
What is the right approach for this kind of problem?
Should I create a different storyboard for each device?
Should I start creating an adjustable scroll view that will hold the needed buttons with some constraints (if at all possible)?
I have read this tutorial:
auto layout
which explains the auto layout nicely, but does not mention the issue I'm trying to figure out.
Any thoughts?
Use AutoLayout and position your views relative to one another (so no x pixels spacing between views). Make only one storyboard for all devices, when a different view should be loaded on another device (like a completely different layout), select the appropriate size class and adapt the views and constraints.
Then it will be recalculated on every device.
The storyboard has a preview section where you can choose a device to simulate the view on.
is there a way to have the view from interface builder in Xcode, be the same size as the iphone we use to test the app? The size of the viewcontroller seems to be 600*600. So when I move a UILabel somewhere to the left for example, it will be placed as if it was on the right on my iphone. Which is not easy to set the right constraints.
Do you have some tips to manipulate the items and place them easily? For now, I just align the item with the center point, and move it little by little.
The reason this happens is because of Apple's emphasis of size classes. It looks like a rectangle because whenever you are adding constraints and views, they'll be applied to every size class (i.e. horizontal/compact, vertical/compact, etc).
In english, it means it's applying those changes to run as such on any device.
To create constraints and views for just one size, you'll want to edit the size class you are working with. At the bottom of Xcode where it says "wAny hAny", click that and you can set what device you want to work with:
The whole idea of this is adaptive design, and I've got a post explaining it in more detail here.
The thing is that there is no one correct size for the iphone screen because there are so many different screen sizes. You can set the view size to anything you want in interface builder by clicking on the view and going to simulated metrics -> size but what you really want is autolayout so that your views fit properly on every device.
