实现iOS开发播放器全屏
整体流程
首先，我们需要创建一个播放器，并添加全屏按钮。当用户点击全屏按钮时，我们需要改变播放器的布局，让它占据整个屏幕。接下来，我们需要监听设备方向变化，当设备旋转到横屏时，自动切换到全屏模式。
步骤表格
| 步骤 | 操作 |
|---|---|
| 1 | 创建播放器，并添加全屏按钮 |
| 2 | 点击全屏按钮，切换到全屏模式 |
| 3 | 监听设备方向变化，自动切换到全屏或退出全屏 |
代码示例
创建播放器及添加全屏按钮
// 创建播放器
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame = self.view.bounds;
[self.view.layer addSublayer:playerLayer];
// 添加全屏按钮
UIButton *fullscreenButton = [UIButton buttonWithType:UIButtonTypeCustom];
[fullscreenButton setImage:[UIImage imageNamed:@"fullscreen_icon"] forState:UIControlStateNormal];
[fullscreenButton addTarget:self action:@selector(fullscreenAction) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:fullscreenButton];
切换到全屏模式
- (void)fullscreenAction {
if (!isFullscreen) {
// 切换到全屏模式
[self.view removeFromSuperview];
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
[window addSubview:self.view];
self.view.frame = window.bounds;
isFullscreen = YES;
} else {
// 退出全屏模式
[self.view removeFromSuperview];
[self.viewController.view addSubview:self.view];
self.view.frame = self.originalFrame;
isFullscreen = NO;
}
}
监听设备方向变化
- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
[super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
if (orientation == UIDeviceOrientationLandscapeLeft || orientation == UIDeviceOrientationLandscapeRight) {
// 横屏时自动切换到全屏模式
[self fullscreenAction];
} else {
// 竖屏时退出全屏模式
[self fullscreenAction];
}
}
