4_2-带货场景-播放器
1 功能概述
视频播放是多场景项目中提供的基础功能，直播带货场景播放器包括直播播放器和回放播放器，直播带货场景模块中播放器主要功能代码在PLVECPlayerViewController中，集成7_3 核心common-播放器中PLVPlayerPresenter来实现的功能。
2 核心类介绍
2.1 初始化及播放
(instancetype)init {
self = [super init];
if (self) {
/// 播放器
self.playerPresenter = [[PLVPlayerPresenter alloc] initWithVideoType:[PLVRoomDataManager sharedManager].roomData.videoType];
self.playerPresenter.openAdv = YES;
self.playerPresenter.delegate = self;
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self.view addSubview:self.backgroundView];
[self.view addSubview:self.playerBackgroundView];
[self.view addSubview:self.displayView];
[self.view addSubview:self.audioAnimalView];
[self.view addSubview:self.playButton];
[self.playerPresenter setupPlayerWithDisplayView:self.displayView];
}
- (void)viewWillLayoutSubviews {
/// ...
}2.2 播放器控制方法
/// 播放直播/回放
- (void)play;
/// 暂停直播/回放
- (void)pause;
/// 静音 播放器
- (void)mute;
/// 取消静音 播放器
- (void)cancelMute;
#pragma mark 直播的API
/// 播放/刷新/重新加载直播
- (void)reload;
/// 切换线路
- (void)switchPlayLine:(NSUInteger)Line showHud:(BOOL)showHud;
/// 切换码率
- (void)switchPlayCodeRate:(NSString *)codeRate showHud:(BOOL)showHud;
/// 切换音频模式
- (void)switchAudioMode:(BOOL)audioMode;3 播放器控制UI
带货场景的播放器控制UI包括屏幕点击控制和回放控制栏控件。
3.1 点击屏幕控制
带货场景的播放器支持双击暂停、单击继续播放功能，此功能是在PLVECWatchRoomViewController的view上加上了单、双击手势实现的，代码如下：
PLVECWatchRoomViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
[self setupUI];
[self setupData];
[PLVECFloatingWindow sharedInstance].delegate = self;
// 单击、双击手势控制播放器和UI
UITapGestureRecognizer *doubleGestureRecognizer = [[UITapGestureRecognizer alloc] init];
doubleGestureRecognizer.numberOfTapsRequired = 2;
doubleGestureRecognizer.numberOfTouchesRequired = 1;
doubleGestureRecognizer.delegate = self;
[doubleGestureRecognizer addTarget:self action:@selector(tapAction:)];
[self.view addGestureRecognizer:doubleGestureRecognizer];
UITapGestureRecognizer *singleGestureRecognizer = [[UITapGestureRecognizer alloc] init];
singleGestureRecognizer.numberOfTapsRequired = 1;
singleGestureRecognizer.numberOfTouchesRequired = 1;
singleGestureRecognizer.delegate = self;
[singleGestureRecognizer addTarget:self action:@selector(tapAction:)];
[self.view addGestureRecognizer:singleGestureRecognizer];
[singleGestureRecognizer requireGestureRecognizerToFail:doubleGestureRecognizer];
}
- (void)tapAction:(UITapGestureRecognizer *)gestureRecognizer {
/** 播放广告中，点击屏幕跳转广告链接 */
if (self.playerVC.advPlaying) {
if ([PLVFdUtil checkStringUseable:self.playerVC.advLinkUrl]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:self.playerVC.advLinkUrl]];
}
return;
}
if (gestureRecognizer.numberOfTapsRequired == 1) {
if (! self.playerVC.playing) {
[self.playerVC play];
}
} else if (gestureRecognizer.numberOfTapsRequired == 2) {
if (self.playerVC.playing) {
[self.playerVC pause];
} else {
[self.playerVC play];
}
}
}3.2 回放控制栏PLVECPlayerContolView
回放播放器控制栏是通过叠加在播放器布局上层封装的PLVECPlayerContolView来实现的。
代码如下：
PLVECPlayerContolView.m
- (void)playButtonAction:(UIButton *)sender {
sender.selected = !sender.isSelected;
if ([self.delegate respondsToSelector:@selector(playerContolView:switchPause:)]) {
[self.delegate playerContolView:self switchPause:!sender.isSelected];
}
}
- (void)sliderTouchDownAction:(UISlider *)sender {
self.sliderDragging = YES;
}
- (void)sliderTouchEndAction:(UISlider *)sender {
if (self.delegate && [self.delegate respondsToSelector:@selector(playerContolViewSeeking:)]) {
[self.delegate playerContolViewSeeking:self];
}
self.sliderDragging = NO;
}
- (void)sliderValueChangedAction:(UISlider *)sender {
if (self.duration == 0.0) {
sender.value = 0.0;
}
}PLVECPlayerContolView在PLVECPalybackHomePageView中实现并与其通讯。
代码如下：
PLVECPalybackHomePageView.m
- (void)playerContolView:(PLVECPlayerContolView *)playerContolView switchPause:(BOOL)pause {
if ([self.delegate respondsToSelector:@selector(homePageView:switchPause:)]) {
[self.delegate homePageView:self switchPause:pause];
}
}
- (void)playerContolViewSeeking:(PLVECPlayerContolView *)playerContolView {
NSTimeInterval interval = self.duration * playerContolView.progressSlider.value;
// 拖动进度条后，同步当前进度时间
[self updateDowloadProgress:0
playedProgress:playerContolView.progressSlider.value
currentPlaybackTime:[PLVFdUtil secondsToString:interval]
duration:self.playerContolView.totalTimeLabel.text];
if ([self.delegate respondsToSelector:@selector(homePageView:seekToTime:)]) {
[self.delegate homePageView:self seekToTime:interval];
}
}PLVECPalybackHomePageView在PLVECWatchRoomViewController中实现并与其通讯。
代码如下：
PLVECWatchRoomViewController.m
- (void)homePageView:(PLVECPalybackHomePageView *)homePageView switchPause:(BOOL)pause {
/** 播放广告中，点击屏幕跳转广告链接 */
if (self.playerVC.advPlaying) {
if ([PLVFdUtil checkStringUseable:self.playerVC.advLinkUrl]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:self.playerVC.advLinkUrl]];
}
return;
}
if (pause) {
[self.playerVC pause];
} else {
[self.playerVC play];
}
}
- (void)homePageView:(PLVECPalybackHomePageView *)homePageView seekToTime:(NSTimeInterval)time {
[self.playerVC seek:time];
}
- (void)homePageView:(PLVECPalybackHomePageView *)homePageView switchSpeed:(CGFloat)speed {
[self.playerVC speedRate:speed];
}
- (void)palyback_homePageView:(PLVECPalybackHomePageView *)homePageView receiveBulletinMessage:(NSString *)content open:(BOOL)open {
dispatch_async(dispatch_get_main_queue(), ^{
if (open) {
[self.liveDetailPageView addBulletinCardView:content];
} else {
[self.liveDetailPageView removeBulletinCardView];
}
});
