如何自动调整 AVPlayerLayer 的大小以在 Swift 的整个父视图上以全尺寸显示视频

Question

Im trying to display a video using the AVPlayerLayer on top of a UIImage . The video is supposed to resize itself so that the full video is shown on the image view, even if it has to stretch itself to do it. Unfortunately I dont get those results, my video end up looking like this instead on the simulator. Image of the results

Ive tried setting the AVPlayerLayer.frame manual to the image views size, to demonstrate what im aiming for it to look like on all the diffrent iPhone sizes. Image of the goal results

Here is my code:

let playerLayer = AVPlayerLayer(player: queuePlayer)
playerLayer.frame = feedBackground.bounds
playerLayer.videoGravity = .resizeAspectFill
feedBackground.layer.masksToBounds = true
feedBackground.layer.addSublayer(playerLayer)

(feedBackground is a UIImage)

dont know if its important but feedBackground's contentMode is scale to fill

Im quite new to app development so thanks for taking you time to read my question and thanks for any solutions you may have:)

Answer 1

Well, i found out a solution. I was integrating the video in viewDidLoad and was setting the playerLayer.frame to be equal to feedBackground.bounds - i think the reason why it wasn't working was bcs the graphics hadn't loaded yet so i couldn't set my videos frame to be equal to feedBackgrounds frame bcs feedBackgrounds frame wasn't calculated / made yet.

Maybe am wrong, either way it worked by moving my code to viewDidAppear or viewWillAppear.
