I know this is a really easy and basic question but this is my 3rd day with this little problem. I know this is a little problem for advanced iOS programmers. I have an app which contains 1 text field, 1 button, 1 background, 1 logo, and 5 labels.
I want to see the same view when I launch at iPhone 4 or iPhone 6, etc. I know I have to use auto layout and constrains but I just started and it's really my 3rd day that I couldn't save the problem.
Can someone please help me? I'm so tired of this
Constraints you'll want to add. By the way, you should become comfortable making dynamic layouts and auto layout in storyboards if you want to make an app.

Don't just copy it, try to understand it and incorporate for the rest of your app. Good AutoLayout tutorials: Ray Wenderlich AutoLayout for iOS 9

I have an swift app where the buttons are off-kilter. I need them at the bottom of the screen and centered. The iOS simulator for iPhone 8 shows the buttons correctly. However, the simulator for the iPhone SE and the actual SE (my iPhone) show the buttons anchored to the right edge of the screen. How can I insure that the buttons are displayed correctly on all iPhones?
First sol
this layout can be done correctly if the center of the middle button is equal to the center of the screen
Second sol
create a UIStackView with these constraints
1- left , right , bottom to screen
2- height say 100
with distribution set to fillEqually , spacing set to say 20
drag the buttons inside it and they will look right in any device
Remove the constraints from the 3 buttons: Calc, Clear, and Help
Align clear to be horizontally centered
Align Calc trailing offset from Clear's leading.
Align Helps Leading offset from Clear's trailing.
Align Clear bottom offset from the bottom margin.
Align Clear, Calc, and Help along to center vertically with one another.
You have two choices: 1) use the legacy struts and springs mode in interface builder to distribute your items as you need them or 2) spend the time learning auto layout, and use it instead. There isn't any easy answer because of all the different screen sizes, and you haven't even considered iPad screens here. The best way to pick up auto layout is to view the WWDC videos on the subject. Yes, it will take longer, but your app will respond better to screen changes, and you will also be able to inherently accommodate new screen sizes.
Use a horizontal stack view for buttons, and set spacing between buttons.
Approach 1 - Set trailing space and leading space, pin the view to bottom and set a fixed height for stack view.
Approach 2 -
Set fixed height and width to stack view and center horizontally, and pin the stack view to bottom.
Always try to use stack view, with that you will reduce the number of autolayout issues you run into.
Please add the constraint for stack view and adjust like that:
I am working on IOS app and its my first app to be build on IOS. I have good experience of developing Android apps. So I have gathered basic information and knowledge about IOS development. I am working on autolayout. But I am not getting it work completely. I have seen Some developers are working on code, But I just want to use IB as I believe there will be some way to handle this.
So looking for help, Please do not down vote my this post As I am posting this after trying almost everything I get on internet.
First take a look at what I have developed and what it is :
in picture there are different numbers of simulator such as Ipad pro 12.9, Ipone 8 plus and I phone se
What I have done so far:
I have taken the View (the white box in middle). I have made it center vertically and center horizontally.
I have set view height as 300 points, and width to match the superview with some margins
I have put the Text Fields for taking Phone and PIN from user and OK button as shown in picture.
Problem & what I want:
- The problem is view is center vertical and horizontal but not its
content are. I want this view to manage its height on the basis of
its content inside. so that It can be looked as center aligned
vertically. Right now its not center align vertically
- Secondly the problem is the width of text fields, as on Ipad they looks too bad. So I really want them to be look good on all devices.
Is there any solution for this using the adaptive/Auto layout? please help me that How can I get this using IB.
Try following solution:-
Fix the width of textfield.
For label use minimum font scale(search on google).
For width and height you have to use adaptive layout.
width = 70% of superview which means multiplier for your view will be 0.7
height = 60% of superview which means multiplier for your view will be 0.6
Refer to the image:-
Equal width with the superview
Set the multiplier as 0.7
#Android Teem,
For this you need to use SizeClasses along with the AutoLayout.
Below I am trying to give you solution.
use items structure as like below. Don't use another UIView inside main view. Instead user StackView. It automatically adjust contents inside it. For more just look for "UIStackView" on Apple Doc.
Next you need to add constraints to stack view as
Leading 10 (for x)
Trailing 10 (for y)
Allign to center (for width)
height stack view will automatically adjust.
Now double click on leading and trailing constraint will open size attributes. Click on "+" icon just before Constant. It will show you a pop up. add Regular Width Regular Height for iPad and set values as 200 (I have give 200, you can give based on your calculation and requirement). this will show like below image
Now Either run or check from preview for all screens. you will get desired results. my changes show result as below
Happy Coding
Here is what you need to do. Go to the storyboard
Right click on the white area of the screen and drag the cursor to the green area.
Few options will appear, select Equal Heights
Now the white dialog box will become equal height to the green screen but don't worry. Select that height constraint and set the
multiplier to let's say 0.5 for 50% height of super view. Repeat the
same for width
Remove the height constraint and hook the bottom most button to the bottom of the view
I am trying to learn auto-layout/constraints but for the life of me I cannot figure out a solution to my problem. I have multiple buttons surrounding a 'main' button. I would like the layout to remain the same and the buttons to auto resize depending on the device AND to remain in the center of the superview. I have been reading and trying and have yet to get anywhere. Any help would be greatly appreciated.
At the moment I am not worried about landscape view but if anyone would like to elaborate that would be great.
Any references I could read or videos would be excellent as well.
Thank you kindly
Example Layout:
I can offer some advice.
Firstly, all your views and buttons should have proportional widths and heights relative to the screen size of the device you're using so it will look decent across different devices.
Secondly, apart from the width and height constraints, your middle "main" button will also have a centerX to your UIViewControllers's view as well as a center Y so you can keep it pinned to the middle. This is important because the other 6 buttons will be pinned relative to this main button.
Let's start with the other buttons, specifically the one above the main button and the one below the main button. These two buttons also have width and height constraints. Now, horizontally, you have two options - since these guys are always in the middle of the screen, you can align their centerX's to the main button, or to the UIViewController's view itself - it doesn't matter as long as it's in the middle. Lastly, we have to consider the vertical distance from the main button. These distances should be proportional to the total height of the screen so it will look good across all devices. You'll be adding a constraint from the bottom of the top button to the top of the middle button. For the bottom button, you'll be adding a constraint from the top of the bottom button to the bottom of the middle button.
Now for the other 4 buttons, apart from the height and width constraints that they will have, you should constrain the horizontal constraints to the top and bottom middle buttons, and then constrain vertically to the main button.
I just started iOS programming and I want to make a login screen. I want to align center horizontally the everything on all devices like the iPhone 5 and iPhone 6 and iPhone 6 Plus but it's not working. I just put the elements on the screen. Anything else i need to do?
There are a few ways you can do this...auto layout as #ozgur said is your friend.
what I would do is throw them into a Stack View
To do that tap each horizontal group so for example "username" label AND the text field to the right and while they are both selected tap the icon at the bottom right that is on the left of the 4 icons (it has a downward arrow)...now do the same for the password...now do the same for the login button...now select all 3 stackviews and tap stackview again...
NOW....on the left navigation select the topmost stackview and then again on the bottom this time tap the small icon to the right of the stackview button...to make it simple and in the center tap horizontally in container and vertically in container then add the 2 constraints....
you will also need a height and width so now once more with the whole thing selected tap the |o| looking icon to the right...now give it the height and width you like but before you tap add 2 contraints at the bottom of that menu is a drop down menu..tap it and select "update all frames in container"
that should do it
Use AutoLayOut Constraints to fix your issue.
Contraints will set the spacing with the view.You have to apply it on every single element of your view.
if you only want every thing in center no different spacing for different iPhone use stack View. it will provide the best solution for you.
stackView means collection of your objects. it act as group of your elements so only apply constraints to your stackview.
Rule of thumb is to use Stack views and then use auto layout. Just put the Username and the text field in a stack view (horizontal stack view), same for the other) and then apply necessary spacing and/or autolayout constraints.
You need to learn how to work with Autolayout (I read you just started) and it could be hard concept to grasp at first (it was for me at least) but with practice, you'll master it.
If you do not use the stack view, you need to learn auto layout and size class for adapting the screen.
auto layout began in iOS 6, sizeclass began in iOS 8.
Here is the official apple documentation, to study it. https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/
Currently i am trying to use AutoLayout on my iOS app in xcode 6. The storyboard I am using consists of only UIButton and UILabel elements, which i would like to resize and fit based on the device. Everything works on the iphone 6 Plus and 6 but when I get to the 5S or 5 things get weird. I can't use size classes necessarily due to both 5s and 6/6P using compact width regular height. IS there a way to fix this?
all images can be found here
Yes! With autolayout there's always a way.
From those pictures it looks like you may have a vertical constraint on the "play" button that is attached to the top of the view. Try putting that constraint on the "How Long" label. That way the button position will be relative to the title instead of the whole screen.
Check to see that you have the following constraints :
Center all buttons and labels horizontally in the container (note,
this is 3 different constraints you need to set). You can select
all 3 at once and from the Align menu center them horizontally in container.
Constrain How Long to Top Layout Guide (Top Space to Top Layout Guide)
Constrain Play to How Long (pin vertical spacing)
Constrain Leaderboard to Play (pin vertical spacing)
Depending on how you want Leaderboard to float you may want to pin it to the Bottom Layout Guide instead of to play. The buttons and labels will then move according to your constraints.
