问题
I use a set of launch images for my app and noticed that when I'm having a call, recording a voice note or sharing my Internet connection and put that activity in the background and launch my app, the launch screen is wrinkled in the center. Is there anything I can do to make the image look ok or is it just a standard iOS behavior?
回答1:
Just define a key in plist file will solve your problem
Status bar is initially hidden = YES
回答2:
OK, the solution I found is to hide status when launching the app, just like here

Seems like Apple "take" 4% of screen space from the middle of the screen (as far as I tested) to give it to status bar. Personally I faced this problem when using iPhone modem mode.
So if it is not critical for image to be centered vertically - the solution would be to place image above/below this "4% middle screen area".
Examples when image is cropped:
How image should look(image centered vertically & horizontally, width & height are fixed size)
How it actually looks
Example when image looks as supposed to (but not centered) :
Constraints example
Image with new constraints example
