I have a imageview at the start and below there are series of buttons placed vertically one below the other. So, while designing the screen, I placed all the views in the view controller and added to vertical stack. Centred stack view horizontally and vertically. For all the buttons, I have set equal width. And in stack view, I have given equal spacing. In all iPhones, it is working correctly with ui elements arranged correctly with equal spaces except iPhone4. In iPhone 4 it is all touching each other. Please find the attachment. What constraint am I missing here?
The problem is the content cannot be fitted in given height.
Let me explain.
Assume small device has height of 480. UIImageView height(intrinsic ) is say 200. You have 4 UIButton of height say 80. UILabel of height say 100. So that sums up to 620.
Views of height 620 cannot fit(all visible without clipping) on a view of height 480.
You need.
Scrollview(To show more content than the available width and/or height)
Reduce the size of you content to fit in 480. To do this you can pin the height of any/some/all to make this height sum less than or equal to 480.
It's because the screen size for iPhone 4 is 480. Your UI seems to be higher than 480. So only the constraints adjusted according to screen height.
Just add height constraint to all button and remove height constraint for image view if added.
Add Height and margin constraints for Buttons and only margin constraints to image view. It will resize according to screen size.
Hope it helps.

hello everyone I've get stuck in Auto-layout issues
I have login storyboard that contains three Items Image-view , Stack-view , Button like the first image below
I've tried to add constraints using two ways:
The first way I've added "pinned" constraint to Image-view as shown in Photo1 below but when I've changed to landscape the Image was disappeared as the second photo below.
please notice I haven't got any warnings
The second Way I've tried by wrap the Image-view using view then i added
"Pinned" constraint to view
finally i added fixed width & height to Image-view and Horizontal & vertical in container but I've got this result as third and fourth photo
what should i do to make my Image-view Adaptive for all Screens ?
thanks

As when changing to landscape screen height changing a lot. the problem with your design with Autolayout is it's not adaptive with landscape and portrait mode because you are give fixed hight and width to your layout.
to make your image-view Adaptive for all screens give your image-view height to superview height in percentage so when in landscape mode height will change your image-view will still gets the height from superview height in exact same percentage.
have a look at this demo hope this will help.
Autolayout
First drop UIImageView into ViewController.
Give it a top constraint and Align it horizontally to it's SuperView.
As now it's only required height and width.
Then Ctrl drag from ImageView to itself and select aspect ratio. give
a aspect ration 1:1 (it's just telling storyboard if any of height or
width is available i want the other to be the same like if width is
given then height should be the same as width, vice versa for height) as you may want
perfect square shape for your profile ImageView.
Now Ctrl drag from ImageView to SuperView and select Equal height.
As now your ImageView got the height to SuperView Height.
give your ImageView proportional height (percentage, Aspect
Ration or Multipiler) to SuperView how much you wanted to give like
so.
At the end your UIImageView will get the height proportional to SuperView height, vice versa for width.
I'm working with my project on the storyboard and I have a problem with screen sizes. It looks simple to solve but not for me. I have an imageView, and its width and height are looking good for iPhone 7/7+ screens. But It is not looking good for 5 or SE Screens.
Can I set different width and height for 5 screens? for example, while 7 and 7 pluses run with 200 width and height, iPhone 5 screens will run with 100 width and height. Or is it possible to squeeze the imageView? When I set the constraints imageView it also needs width and height for looking well, but it prevents to squeeze the imageView as well.
If you want the imageView to squeeze, you shouldn't give it a static width or height in the constraits.
One way to go is to set the leading, trailing, top and bottom constraints for it ==> no need for a width or height constraints.
Another way is to give it a proportional width and height, and this can be done by giving the image view an equal width and equal height constraints to its parent view for example, and then set the multipliers of these constraints to some number, 0.5 for example, this way the image view will always take half of the parent view's width and half of its height.
Please look at the ScreenShot attached for wCompact|hRegular for different screens, I am trying to make it working since hours but not getting any success. My requirement is that at the top there would be a label with some predefined margin. Although the Label content would render at the runtime, but I know the content size, so resizable label isn't needed actually I think. Now there would be three row at equal distance. In first and third row, there would be two buttons with equal height and width and in second row there would be button aligned horizontally. I have set the buttons image and text in storyboard. Control Alignment are set to Horizontal | vertical. Constraints for label are:
Pinned top space to superview, leading and trailing space equals to:8(superview), height equals:90.
Constraints for Button(View Transactions) are:
top space to label, bottom space equals to:8(New Launches Button) leading and trailing space equals to:8(superview) and 8(Place Request Button) respectively, and equal width and height for all buttons.
Looks fine for 4.7 and 5.5 But not satisfied with the output for smaller screens. As u can see resizing of buttons image not working properly(Larger space between button's image and text). One more thing is I don't wanna set the height of the label, cause it seems like a wrong practice in AutoLayout. Any help would be much appreciated.
You should set the Aspect Ratio for the Buttons, not just the equal width and height. In that case auto layout wont shrink the images.
Really you should put this into a scroll view so that if the height is too great the user can still see everything by scrolling. You should also not set static heights on labels, you should allow the intrinsic content size to apply.
Add a subview to your new scroll view. Pin the width of this subview to the width of the scroll view. Do not pin the height.
Add all of your buttons and labels to this new subview. Pin them to the edges of the view and allow the intrinsic content sizes to apply limits. Set various items to have equal widths and heights. Do not set explicit heights or widths (do everything by proportion or equality so auto layout can choose good sizes).
I am trying to arrange controls in the storyboard using constrains via Interface Builder ("Any Width, Any Height" case). I add there UIView, however, when I press update frames for this element (Selected Views case) according to the given constrains UIView disappears from my view. I guess it size becomes zero. Later on, it is not show up in the screen after the run. The issue is also reported in the issue navigator: Horizontal Position of UIView is ambiguous (marked with the green shape). Anyway, if I set the constrain for width or height (size parameters) together with the constrain of ratio, then the issue disappears, I can update frames, it shows up in the screen during the run.
I am adding the picture with the green marks to make the issue more clear:
The question is whether the parameters of the size are obligatory when I am setting the constrains.
Even if they are obligatory how I can make the size to fit different sizes of the screens or iPhone+iPad because if I set/fix the size it could too big for some screens.
The size is not mandatory. The warning tells you that you must set an X position for this view (constraint between the superView left or right border and the left / right border of the view itself). If you want the view to resize itself to fit each screen size you must set both left and right constraint without the size constraint.
You shouldn't used fixed size (width or height) for view that change size when screen dimension change.
If you want view that fix aspect ratio you can set size that relative to Superview's width or height using:
1) leading and trailing and make sure that
view.leading = superview.leading + fixed_margin
view.trailing = superview.trailing - fixed_margin
and not other way around.
2) equal width or equal height with multiplier, constant relative to superview as you want
So you don't need evil size class.
This answer: https://stackoverflow.com/a/25898949/1364053 is suitable for my problem to some extent. What I need is there are three views in my container view.
The middle one is a scroll view. If I pin height and width of all three views and use the ratio method as described in the above link, all works fine.
But I need the middle scrollview to grow to some extent, let's say the current height of the scroll view is 30, If the device height is increased it should grow to a max of 40 but not more than that (<= constraint).
Ok..So I tried giving two constraints to the middle view. The <= constraint has higher priorty (750) than the = constraint (250).. but when the screen size is increased.. the height stays the same.
