Autolayout Issue with Multiple Button Aligned Horizontally & Vertically with a Label

Question

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.

Answer 1

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).

Answer 2

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.
