I encountered a weird error when using
UICollectionView, where the storyboard is using autolayout.
This is the error:
Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) ( "<NSLayoutConstraint:0x7fda6411de70 H:[UIButton:0x7fda6411dc90(13)]>", ... "<NSAutoresizingMaskLayoutConstraint:0x7fda61cf61e0 h=--& v=--& H:[UIView:0x7fda6411d500(50)]>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x7fda6411de70 H:[UIButton:0x7fda6411dc90(13)]>
It doesn’t crash as it is able to recover by breaking constraint.
It is weird becase:
If I try to solve by breaking the constraint, it will not layout as I wanted
I checked every constraints and they are valid and minimal; I need not remove any unwanted constraints
The problem lies with the view cell.
contentView must set
This will similarly apply to
It seems like the content view cell must use auto resizing mask.
