I want to insert 4 Subviews with exact 25% percent width of the SuperView.
So, my question is how to achieve that with XCode's Autolayout? In Android I would use a GridLayout or a LinearLayout...
Thanks in advance
Just set your constraints like this image,you will get what you want
And this is preview in different screen sizes
You have to select all the four views, and add top, bottom, left, right constraints to zero and equal width constraint.
Your constraints should look like this.
In the screenshot, the four views are arranged over a container view. If you dont't want the container view, then you have to specify the height constraint also.
You should use UIStackView that is introduce in ios9 and xcode 7.0
Here is a link of the tutorial have a look its like a linear layout in android

There are alot other ways as this is the new one and it help to reduce work and time both so you should use it.Thanks

I am having some major issues with my constraints, all I did was select add missing constraints and it looks fine in my storyboard and on an iPad like so,
But when I run it on iPhone, it looks like this:
What do I need to add to fix this issue...this is what I got so far:
Don't relay only on Add missing constraints , you have to make your edits after applying them
I see some constraints with leading
949,344 and 283+
and this may exceed width of some iphone screens
Simply remove any leading and trailing , and centerX the items with width constraints
also using UIStackView is good for the lower textfields
The easiest way to solve your problem with the constrains in my opinion for this type of layout is to embed your views in to Stack View. With Stack View you can easy center this views in to Screen by adding some costrains to the Stack View. With Stack Views if you need some adjustment you can do it only with few mouse clicks.
Select all your views
Click embed in the Stack View
Delete constrians that you don't need
Adjust alignment, distribution and spacing
Add trailing, leading and heigh constrian
Now it should looks good.
I need my buttons to stay in the same positions for all phones.
I want it to look like this on all iPhones:
But when I switch to a larger size phone it does this, it also looks ugly on smaller phones as well:
That is a VERY broad question, as a lot of iOS UI depends on autolayout. I suggest you work through these tuts at at least AutoLayout. From your screen shots, it looks as if you have set a width constraint on your view with the green background instead of pinning the leading, trailing, top, and bottom to the edges.
Auto layout is, in essence, a system that performs calculations based on constraints. This means that to perform what you want, you need to add constraints to each of your objects so that the compiler knows how you want to resize your UI. But like others have said, that is a very general question. I suggest looking into the topic a bit before asking, so you can narrow down your question and get better answers.
You need to define positions for all your button or views. You need to define atleast 4 constraints for all your view. By adding constraints you tell your views where they should be placed on all screens. You define their positioning with respect to screen by adding constraints.
When you add trailing, from top and width and height constraint you tell that view should be placed in fixed position i.e. x , y and occupy defined space whatever may be screen size.You can opt for fixed width or height. Instead of fixing height and width you can also define leading or trailing constraints for the view. Constraints will adjust views frame according to screen size.
For beginning you can opt for some tutorials available online. You can check Raywanderlich here. Hope it helps.
What constraints would make this view resize the labels 1-9 with a smaller font and label size in order to keep labels 1-9 within the view. I have tried using minimum font scale and pinning the labels to all sides of the view. Any tips and or help with auto layout and building responsive UI's in Xcode are appreciated thank you.

iPhone 4s screen size simulation
It's easy!
You can use constraints like this:
After adding all constraints you need check UILabel configuration:
If you have question - you can ask :)
I think here, you can find answer to your question (Part: Two Equal-Width Views).
A idea lies inside of using additional view between the labels and strengthening first and last labels to a top and a bottom edge of a parent view.
All you have to do is add some NSLayoutConstraints and change some UILabel Properties in the UIStoryBoard Interface Editor .. I have added an image and a gif for reference.
This gif image will give a detailed explanation :
I am developing an iPhone app in which, i have made this page using autolayout
but it shows unwanted spaces above Register Me(yellow button) in bigger iPhones
Constraints given are:
top,bottom, leading and trailing with respect to its subviews to all the controls. (there is no warning or misplaced constraints i see in xcode)
Here is the screenshot of iPhone 4s
Here is the screenshot of iPhone 6+
I want to minimize the empty spacing in bigger iPhones...
How do i solve this problem?
Please help and thanks in advance
Heres a suggestion for you. You have roughly seven regions of interest there. First one is the title 'Register Kano .. ' etc. Then there are 5 text entry areas - name, email, password, etc. Finally you have 3 small lines of info text - I would count this as one final area, so 7 in all.
What I would do is create 7 parent UIViews to put that stuff in. I would give them 'equal height' constraints, and make them sit above and below each other with no gap. Then as the iphone screen changes height, those areas stretch out height-wise to fill the area. Heres a rough mockup :
Select all those UIViews and select the 'equal heights' constraint :
Then every view except the bottom one needs these constraints (top, leading trailing to superview 0px)
Then your bottom view needs those plus 'bottom' too :
So all that remains to do is to put your content in each of those boxes, but centre them in terms of vertical position relative to their superview.
If your intent to target iOS 9 users, you should use UIStackView, the provide a lot of flexibility in terms of alignment and distribution.
If not, then you or your design team has to find a solution.
You can update the margin contraints of your controls on big devices.
This would add space between each rows on big screens, will looks better as you ask.
Something like :
myControl.heightConstraint.constant += 20.0f
This is how I would do, but you have to decide how you update your layout for big devices
#Krunal you can use the size class and set the constraints accordingly so it will give a brief idea how to fit the UI design for every device!!
you can set constraints relative to height of your base view. This will make your interface objects evenly distributed over layout. Lets assume you have 8 regions. for registerLabel
registerLabel.leading = baseView.leading
registerLabel.trailing = baseView.trailing
registerLabel.top = baseView.top
registerLabel.bottom = baseView.bottom * (1/8)// it will be always proportional to height of view
then for icons at the beginning firstIcon
firstIcon.leading = baseView.leading + 10
firstIcon.height = firstIcon.width
firstIcon.height = baseView.height*(1/9)// to give a gap between icons
firstIcon.bottom = baseView.bottom * (2/8)
and then you can set textfield's constraints according to firstIcon
for other icons you can go on with 3/8, 4/8, 5/8, 6/8 and set the relative textfields constraints according to that icon.
and lastly for registerMe button
registerButton.leading = baseView.leading
registerButton.trailing = baseView.trailing
registerButton.bottom = baseView.bottom
registerLabel.height = baseView.height * (1/8)
With this approach your icons size also decrease and increase relatively with height of view and all the page will be filled.
baseView is view of controller.
What is happening here, you kept the width according to superview ie phone width, but your height is fixed.
Do one thing instead of giving Height constraint, use aspect ration in combination with leading , trailing and top constraint. When view will stretch widthwise , your component's height will also Increase and fill the extra space for iphone 6.
This is the best thing you can do keeping the same layout and design pattern.
Seems you have given some fixed height in views.
As every element is depends on it above and below elements constraints, this might be possible of empty space.
So try to divide the View part then the dependency of constraints will reduce.
If you don't want to show empty space, then use center horizontally to one of the element which will look good, here it may be the third field.
Then start giving same constraints to Register button. Sure it will help you in resolving this issue.
Hey its the best solution for you is stackView
Combine your objects in single stackView.
You can combine your object vertically and also horizontally.
It will decrease your space and view will arranged in awesome manner.
You can select your objects like this.
Click here to make it stack.
Now you can reduce your space like this.
I've seen a lot of different topics and suggestions on aligning and inputting buttons/text, but the ways I've seen seem kind of risky.
What is the optimal way, for example, to add two buttons, stack them together, and have them be 10% from the bottom of the screen, and centered horizontally on all devices?
Learn Auto Layout if you haven't yet. Use constraints for achieving the following:
For centrally Horizontal on all devices: Use Center X with SuperView.
For having them 10% from bottom, use multiplier value say 0.10 .
The optimal way would be using storyboard for implementation and use of constraints in a proper way.
For example, as you suggested you want bottom space to be 10% of device height so it can be done with the multiplier in constraints also the horizontal center can be easily done with the same, so you could look for a good tutorial of Auto Layout and constraints for better understanding.
Use your Storyboard and add Auto Layout to your elements. Here is an example:
I have added auto layout
Left
Right
Top
Bottom
If I want to change the distance between the buttons, I just choose the auto layout constraint that I have created between the buttons and changes the constant value to it.
If I say that "Button 4" constant to the top shall be 40, then it´s always 40 no matter what size the phone has. If I change the constant between the buttons to 10 then it´s the same for all sizes.
Your best bet is to use Auto Layout. It takes a bit of learning but once you get used to it you can add constraints pretty quickly and easily in Interface Builder. I can't recommend any particular guide but there are a lot of good ones to be found with a quick Internet search.
Here is an example of constraints that seem to be what you are looking for:
For iOS 9, an even simpler Auto Layout approach would be to use UIStackView.
As you can see, no constraints are needed for the buttons embedded in the stack view, as the stack view lays out the buttons for you. All you have to constrain is the location of the stack view itself.
Here's an example of two vertically stacked buttons, 10% from the bottom of the screen, and centered horizontally for all devices.
