I have developed my App on XCODE 8 which by default removes iPhone 4 emulator and I didn't notice that until I finished my app, and I used Auto layout to make the UI fits all iPhone screens and that what happened (the layout was good on iPhone 7,6,5) the problem is when I additionally installed iPhone 4 emulator I found that the layout is totally missed up and unreadable/usable.
So what options do I have to solve this and make it fit the iPhone 4 screen too with Auto-Layout with missing up the other sizes ?
Here is screen shot of my Login screen on iPhone 6 (4.7") vs iPhone 4 (3.5")
You must always give constraints with respect to other alternative buttons or a view, it should not be hard coded. Try making views programatically, it will be more easy and helpful to you.
It seems like your constraint is set to have a fixed distance related to the top of your screen. So when the screen height get smaller, your views are pushed out of the screen. So to better adjust views position, you can have your views to be related to vertical center. Say your login box is in both horizontal and vertical center, not metter you are using iphone 6 or 4, you should always see your login box.

I'm creating a simple app that includes a table view using Swift 5 and Xcode 11. Inside the table view(which, by the way, is fixed into landscape), there is a button on the right of the tableview cells and an image view with fixed constraints, size, and width on the left. Everything has been working out pretty well for my app, until I noticed that the image view would kind of 'disappear' if I changed the device to, for example, iPhone 5s, 4s, or even iPhone Pro(I'm testing with iPhone 11 Pro Max).
This is when the device is iPhone 11 Pro Max:
11 Pro Max
This is when the device is iPhone 11 Pro: 11 Pro
And here are my constraints for my image view: Constraints
Any help is appreciated
P.S. Ignore the image view that says 'img'
After seeing both of the screen shots and the constraints I see what is the issue here.
It's the way you have applied the trailing constraint for the image which in your case is 663 (Should not be fixed). What you can try is Give width constraint to the image view and then change the trailing constraint something like below
This should help you.
Also what you have to take care of moving forward is the constraints you choose to apply coz that is the most important thing while desigining Responsive UI
Happy Coding.
right Constraint should be negative,for example,
img.snp.right = view.right - 20
I am new to Xcode, and have been trying to figure out how to use AutoLayout and constraints. Long story short, after I hit 'add missing constraints' the Iphone 7 screen looks just as I intended, but both the Iphone 7 plus and Iphone SE screens look completely screwed up. What can I do to fix this so that every screen looks like the Iphone 7?
Iphone 7
Example Iphone SE (screwed up)
add missing constrains option means: adds the constraints needed to have a nonambiguous layout. may not work well for all iOS devices, and may not work well for device's rotation changes or view size changes, so, check view's constrains in size inspector panel
for more info:check Apple's auto layout guide
So basically I'm designing a layout for my app and I have difficulties adjusting my layout for iPhone 4. For an example look at these screenshots:
As you can see it barely fits on the iPhone 4 and the iPhone 6 has a blank space on the bottom. Am I using Auto Layout incorrect or is this the intended behaviour?
I also struggled not being able to make text fields smaller to fit the iPhone 4 screen in another layout.
Help would be much appreciated!
if you embed all views in a UIScrollView (with autolayout set), your content will be always visible(scrollable)
if you use size classes, you can set a specific UX for iPhone4
I'm working on an iOS app and realize the ui is not auto stretch to fit the screen when it's running in iPhone 6 plus.
So the UI is on the right left, and there are a lot of white space in the bottom and right.
If I set the width of a view to beyond 320 (ex. 400), then the view be wider than 320.
How could I make my views auto stretch to fill the screen?
I have a few other apps, and they works perfectly fine in iPhone 6 plus.
I couldn't figure out what make this app's ui not auto stretching.
The only difference I could think of it this one is create after the official xcode 6 is released, the others were created in xcode 6 beta version
Thanks!
Seems like you enabled native resolution for iPhone 6 Plus. If you delete "launch screen file" you can individually control which screen size will be supported as native resolution by adding related size of launch images.
You should start using auto-layouts. Start from here: Auto layout guide
I am using Xcode 4.5 and iPhone 4 and 5 simulator, and the Interface Builder would add a UIButton in the top half of the screen with a top constraint, and add a UIButton in the bottom half of the screen with a bottom constraint.
It works fine on an iPhone 5 simulator, but on the iPhone 4 simulator, the buttons can overlap, or the bottom button may even get positioned above the top button.
I think it is due to the constraint, such as the bottom button "must be 250 points away from the bottom margin". I can't delete the constraint, and if I change it to "250 points or less", it won't work, if I change it to "250 points or more", it won't work either.
Is there a way to:
1) Make it have no constraint, but just position at absolute x and y? (or what about the spring in the past, so that everything is more spaced out in iPhone 5?)
2) Make the NIB into a one for iPhone 4 and 4S only, so that the app works well on iPhone 4 and 4S and just "black barred" on the iPhone 5.
3) Make it work well on iPhone 5 and work well on iPhone 4 as well?
If you know solutions to only (1), (2), or (3), above, please give it regardless, as it is still a viable solution for the transition period.
It is actually very easy to reproduce: Create a simple Single View app using Xcode 4.5, and drag one button just above the center point of the screen, and another one just below the center point of the screen. Then run it on the Simulator. On iPhone 5, it is:
And now stop the app, and change the Device in the Simulator to iPhone 4S (3.5 inch Retina). If you don't stop the app first, the Simulator can crash. Now run the app again, and the buttons will overlap:
I had the same problem, and it was due to a wrong settings for autosizing. To change the autosizing, click on the control in the interface builder, go to the size inspector.
Notice the bold red I's in the autosizing grid, they control placement when the screen is resized (like when going from iPhone 3GS to iPhone 5.
I think it will work best for you if you make your autosizing look like this:
I'm not sure, since I haven't used constraint-based layout (and won't until we drop support for iOS 5). Traditional NIB-based autoresizing will do absolute coordinates.
You can't do that for just one screen, as far as I know — you can disable it for your whole app by removing Default-568h#2x.png.
I'd go for programmatic layout, or if you want the easy way (which will be a pain to maintain), different nibs for different screen sizes. Note that you'll want to correctly handle the in-call status bar too...
EDIT: Put the two buttons in a container view and make the constraint center the container inside its parent? It won't adjust the spacing between buttons, but should look okay on both devices.
Select your buttons and add "vertical spacing" constraint for them. And set "less than" for top/bottom margins.
