在ios中为AV Player ViewController定义视图框架大小 [英] defining view frame size for AV Player ViewController in ios

问题描述

如何在iOS中将视频作为背景播放?我遵循了这个问题如何使用Swift播放本地视频?，但是AV Player ViewController是一个控制器，不能让我决定包含视频的视图的位置和大小.它总是带有一些预定义的值.

How does one play a video as a background in iOS? I followed this question How to play a local video with Swift?, but AV Player ViewController is a controller and doesn't let me decide where and how big the view containing video is. It always takes some predefined values.

推荐答案

对于已经完成的项目，我已经完成了此工作，但是没有使用AVPlayerViewController-我只是将普通AVPlayer添加到视图的图层中.我有一个收藏夹视图，但您可以将视频插入到任何需要的图层上.尝试这样的事情:

I've got this working for a project that I've done but not with an AVPlayerViewController - just a plain AVPlayer that I add to a view's layer. I have a collection view but you can just insert the video on a layer wherever you want. Try something like this:

NSString *filepath = [[NSBundle mainBundle] pathForResource:@"my_local_file" ofType:@"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
self.avPlayerItem = [AVPlayerItem playerItemWithURL:fileURL];
self.avPlayer = [AVPlayer playerWithPlayerItem:self.avPlayerItem];
self.avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:self.avPlayer];
self.avPlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
self.avPlayerLayer.frame = self.view.bounds;
[self.view.layer insertSublayer:self.avPlayerLayer below:self.collectionView.layer];
// could also try [self.view.layer insertSublayer:self.avPlayerLayer atIndex:0];
[self.avPlayer play];

基本上，将AVPlayerLayer.frame设置为所需的大小.

Basically, set the AVPlayerLayer.frame to the size that you want.
