前言

ZFPlayer demo中已經(jīng)列出各種場景的使用,由于公司項目類似于微博,不只是有視頻的展示,tableview由多種復(fù)雜cell組成,為了完美適配,所以更改了部分源代碼

正文

1. 初始化播放器,設(shè)置屬性,回調(diào)等

ZFPlayerController初始化要給定對應(yīng)的View的tag,這個View一般是UIIMageView用來在cell中展示封面的,ZFPlayer內(nèi)部完全是根據(jù)tag查找View來進行設(shè)置播放視圖的

    ZFAVPlayerManager *playerManager = [[ZFAVPlayerManager alloc] init];
    self.player = [ZFPlayerController playerWithScrollView:self.storyTableView playerManager:playerManager containerViewTag:999];
    self.player.controlView = self.controlView;

此處的controlView即ZFPlayerControlView,它有兩個關(guān)鍵子視圖ZFPortraitControlView和ZFLandScapeControlView,分別是豎屏全屏和橫屏全屏的播放視圖

ZFPlayerController可以設(shè)置很多屬性,可以選擇移動網(wǎng)絡(luò)是否自動播放,也可以直接控制是否自動播放

    // 移動網(wǎng)絡(luò)依然自動播放(默認(rèn)NO)
    self.player.WWANAutoPlay = NO;
    //自動播放
    self.player.shouldAutoPlay = NO;

播放停止之后重置播放器

    MyWeakObj(self);
    self.player.playerDidToEnd = ^(id  _Nonnull asset) {
    [selfWeak.player stopCurrentPlayingCell];
    };

旋轉(zhuǎn)屏幕做的處理

    self.player.orientationWillChange = ^(ZFPlayerController * _Nonnull player, BOOL isFullScreen) {
        [selfWeak setNeedsStatusBarAppearanceUpdate];
        [UIViewController attemptRotationToDeviceOrientation];
        selfWeak.storyTableView.scrollsToTop = !isFullScreen;
    };

播放時間大于0.2隱藏視頻封面,也即之前設(shè)置的tag對應(yīng)的View

這樣的處理的原因在于,播放器在開始播放之后會有短暫的黑屏過程,主要是由于開始播放之后ZFPlayerLoadState狀態(tài)為ZFPlayerLoadStatePlaythroughOK,但是存在短暫的解析過程,視頻的第一幀并沒有出現(xiàn)

    self.player.playerPlayTimeChanged = ^(id<ZFPlayerMediaPlayback>  _Nonnull asset, NSTimeInterval currentTime, NSTimeInterval duration) {
        DLog(@"當(dāng)前播放時間=%f",currentTime);
        if (currentTime > 0.2) {
            selfWeak.controlView.coverImageView.hidden = YES;
        }
    };

2.屏幕旋轉(zhuǎn)處理

對于包含UITabbarController和UINavigationController的控制器,需要分別實現(xiàn)三個方法

UITabbarController

- (BOOL)shouldAutorotate
{
    return [self.selectedViewController shouldAutorotate];
}

- (NSUInteger)supportedInterfaceOrientations
{
    return [self.selectedViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return [self.selectedViewController preferredInterfaceOrientationForPresentation];
}

UINavigationController

- (BOOL)shouldAutorotate {
    return [self.topViewController shouldAutorotate];
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return [self.topViewController supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return [self.topViewController preferredInterfaceOrientationForPresentation];
}

對于父控制器包含子控制器的情況,如果在子控制器中有旋轉(zhuǎn)屏幕的需求,那么父控制器也要實現(xiàn)shouldAutorotate方法

3.滑動播放當(dāng)前正在顯示的cell

需要實現(xiàn)下面幾個方法

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView {
    [scrollView zf_scrollViewDidEndDecelerating];
}

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate {
    [scrollView zf_scrollViewDidEndDraggingWillDecelerate:decelerate];
}

- (void)scrollViewDidScrollToTop:(UIScrollView *)scrollView {
    [scrollView zf_scrollViewDidScrollToTop];
}

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    [scrollView zf_scrollViewDidScroll];
}

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
    [scrollView zf_scrollViewWillBeginDragging];
}

zf_scrollViewDidStopScrollCallback這個回調(diào)可以返回當(dāng)前正在顯示的cell,實現(xiàn)播放方法即可

      // 停止的時候找出最合適的播放
        MyWeakObj(self);
        _storyTableView.zf_scrollViewDidStopScrollCallback = ^(NSIndexPath * _Nonnull indexPath) {
            [selfWeak playTheVideoAtIndexPath:indexPath scrollToTop:NO];
        };

問題: ZFPLayer寫的關(guān)于尋找當(dāng)前正在播放的cell本身是沒有問題的,但是只是不適合我公司的項目而已,在UIScrollView+ZFPlayer.m的zf_filterShouldPlayCellWhileScrolling方法中,根據(jù)tag查找到對應(yīng)View之后只做了是否存在的判斷,而我的邏輯是隱藏,所以計算的當(dāng)前顯示的cell,總是會有問題
