話不多說 先上圖

根本思緒 1.把 AVPlayerLayer加載到 UIView 上 UIView 加載到 ScrollView上,講player加載到一個可變數組裡 2.滑動 ScrollView的時分切換 view 的頁面 切換 view 的頁面,先把上一個頁面的播放器暫停並且把它重置到初始形態 將以後也頁面的播放器從數組外面取出加載播放 1.預備步驟 (1)幾個本地視頻資源 這裡示例講到的是.mov 格式的 (2)playVideoArray = [[NSMutableArray alloc]init]; 2.代碼進程

//預備代碼 用 for 循環給 scrolleview 和數組添加內容
//示例只要兩個資源就運用的2個了

for (count = 0 ; count <  2; count++) {

        NSString *urlStr = [MSPath fullPathFromAssetsInMainBundle:[NSString stringWithFormat:***這裡寫上你的資源途徑***@"guideMov/guideMov%d.mov",count+1]];
        NSURL *videoURL = [NSURL fileURLWithPath:urlStr];

        AVAsset *movieAsset = [AVURLAsset URLAssetWithURL:videoURL options:nil];
 //運用playerItem獲取視頻的信息，以後播放時間，總時間等
    AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:movieURL];

        AVPlayerItem * playerItem = [AVPlayerItem playerItemWithAsset:movieAsset];

        //創立AVPlayer  播放器
        AVPlayer * player = [AVPlayer playerWithPlayerItem:playerItem];

        //創立一個AVPlayerLayer  用於加在 UIView 上
        AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
        playerLayer.frame = self.view.bounds;
        playerLayer.videoGravity = AVLayerVideoGravityResizeaspect;


        UIView *playView = [[UIView alloc]initWithFrame:(CGRect){pw * count,0,pw,ph}];
        //將playerLayer參加 UIView 的 layer 層
        [playView.layer addSublayer:playerLayer];

        [mScrollView addSubview:playView];

        //把player 加載到 playVideoArray 數組裡
        [playVideoArray addObject:player];

        if (count == 0) {
            currentMovieIndex = count;
            [player play];
        }
 }

以上的代碼是預備任務

上面是 scollerview 的代理辦法

pragma mark UIScrollView delegate

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    //更新UIPageControl的以後頁
    CGPoint offset = scrollView.contentOffset;
    CGRect bounds = scrollView.frame;
    NSInteger pageChange =  offset.x/bounds.size.width;

    if (pageChange == currentMovieIndex) {
        return;
    }

    if (self.guideArrow) {
        [self.guideArrow removeFromSuperview];
    }
    //拿出上一個的播放器 

    AVPlayer *prePlayer = [playVideoArray objectAtIndex:currentMovieIndex];
    //把它暫停
    [prePlayer pause];
    //把它重置
    [prePlayer replaceCurrentItemWithPlayerItem://(這個是取出播放器)[self getPlayerItem]];

    currentMovieIndex = pageChange;
    //拿出以後的播放器
    AVPlayer *curPlayer = [playVideoArray objectAtIndex:currentMovieIndex];
    //停止播放
    [curPlayer play];

    [mPageControl setCurrentPage:pageChange];
}

- (AVPlayerItem *)getPlayerItem{
    NSString *urlStr = [MSPath fullPathFromAssetsInMainBundle:[NSString stringWithFormat:@"guideMov/guideMov%ld.mov",currentMovieIndex+1]];
    NSURL *videoURL = [NSURL fileURLWithPath:urlStr];

    AVAsset *movieAsset = [AVURLAsset URLAssetWithURL:videoURL options:nil];
    AVPlayerItem * playerItem = [AVPlayerItem playerItemWithAsset:movieAsset];
    return playerItem;
}

//以上就是完成視頻引導頁的播放了 同理也可以用來循環切換播放本地視頻
