问题 I used command-delete to remove some constraints on the Map View widget in IB. Instead of being completely removed, the constraints are actually just faded as shown in the attached picture. I have tried both saving the file and reopening the project, but it seems like they will not be removed by XCode. How can I get them removed?

问题 I have a UIView inside a UIScrollView . I can easily pin the height to the UIScrollView 's frame height. How do I add a constraint that pins to the UIScrollView's contentSize instead?

If you put a UIView inside a UIScrollview and Pin fixed constraints in Interface Builder it will generate an error because the parameters are relative to Superview/Container View. You can try some

If I remove the host application this goes away but the tests also fail. Does anyone know where I'm going wrong? 回答1: We had the same

问题 I setup constrains in wAny hAny size class, and it worked on iPhone & iPad simulators. Then I switched to wAny hCompact size class and made some changes It looks good in iPhone landscape mode, but change nothing in iPad, because iPad is wRegular hRegular. I try to apply these constrains to wRegular hAny size class, but can't find a quick way to do that. It makes no sense to manually modify all the constrains again. I found that if I double click a constrain in Inspector panel, there's a
