ios - Detect device rotation inside a collectionViewCell -

-



inside custom collectionvirewcell create gradient layer , add cell in function override func awakefromnib() {}

 self.layer.insertsublayer(gradient, at: 0)

when device rotates size of cell changes not size of layer. need 

override func viewdidlayoutsubviews() {     gradient.frame = self.bounds

}

the problem error telling me viewdidlayoutsubviews() did not override function superclass. there method detect cell size variation inside cell class?

viewdidlayoutsubviews() uiviewcontroller method , not method of uiview uicollectionviewcell inherits from.

the method you're looking override layoutsubviews()

override func layoutsubviews() {     <#code#> }

i think that's problem!
