自动布局仅在iPhone 7 plus中不起作用

Question

autolayout is not working only in iPhone 7 plus

it can't be center both horizontal and vertical

it looks like this

there is some space, it's not fit! but, it work well in other iphone device

here is iphone 7 ( there is no empty space compare to iphone 7 plus )

I can see that image alignment is x,y center in indicator

here is constraint

image size is

@1x:320x100 / @2x:640x200 / @3x:960x300

I think image size is correct...

Answer 1

What is your imageView.contentMode ? It seems like it is not scaling up the image. An iPhone 7s width is 414pt . 414pt - 28pt * 2 = 358pt . Your image would have to be at least 358pt wide to not have any padding and not require upscaling. That would be 1074x336 for the @3x dimensions.

Alternatively, just set the contentMode to .scaleAspectFill . Rather than having the rounded corners in the image itself, you could set the imageView to have rounded corners, to make scaling easier.
