objective-c - 弹出 MPMoviePlayerController

Question

正在开发一个 ipad 应用程序，我想在其中弹出所需大小的 MPMoviePlayer Controller (例如屏幕的 3/4)。如何实现？

Answer 1

您可以在任意位置添加 MPMoviePlayerController View (它不是 UIViewController 子类，但有一个 view 属性，即 UIView)(您也可以根据需要设置其框架)

moviePlayerController.view.frame = yourCustomFrame;
[otherView addSubview:moviePlayerController.view];

A movie player (of type MPMoviePlayerController) manages the playback of a movie from a file or a network stream. Playback occurs in a view owned by the movie player and takes place either fullscreen or inline. You can incorporate a movie player’s view into a view hierarchy owned by your app, or use an MPMoviePlayerViewController object to manage the presentation for you.

要将其集成到 UIPopoverController，您可以创建 UIViewController 的子类，例如具有 MPMoviePlayerController 属性的 YourVideoViewController(并将 MPMoviePlayerController View 添加到其自己的 View 中)，然后使用 YourVideoViewController 创建 UIPopoverController。

您有 MPMoviePlayerController 同步

- (UIImage *)thumbnailImageAtTime:(NSTimeInterval)playbackTime timeOption:(MPMovieTimeOption)option

电影必须加载(您必须注册加载状态更改通知)，或异步

- (void)requestThumbnailImagesAtTimes:(NSArray *)playbackTimes timeOption:(MPMovieTimeOption)option

API。在后一种情况下，您应该注册 MPMoviePlayerThumbnailImageRequestDidFinishNotification 通知以获取缩略图。
