本人水平较低，还需进行优化，有不足的地方还请评论指出，多多指教，谢谢。

最初使用的是36 氪开源项目KRVideoPlayer完成视频播放功能，但是无奈全屏的时候状态栏还是竖屏，最初为了开发进度就横屏隐藏状态栏了，但是感觉后期还需要完善，so，根据KRVideoPlayer的逻辑自己进行了一个简单的优化封装（部分代码仿照KRVideoPlayer）。

将播放的视图aView添加到HFVideoPlayerControlView上即可，用法如下：

    HFVideoPlayerControlView *videoPlay = [[HFVideoPlayerControlView alloc] initWithFrame:CGRectMake(0, 64, self.view.bounds.size.width, self.view.bounds.size.width*9/16)];
    videoPlay.delegate = self;
    videoPlay.currentTimeLabel.text = @"12:59:59";
    videoPlay.totalTimeLabel.text = @"12:59:59";
    [self.view addSubview:videoPlay];
    
    UIImageView *aView = [[UIImageView alloc] init];
    aView.image = [UIImage imageNamed:@"16091G34I9-6.jpg"];
    aView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.3];
    aView.frame = CGRectMake(CGRectGetMinX(videoPlay.bounds), CGRectGetMinY(videoPlay.bounds), CGRectGetWidth(videoPlay.bounds), CGRectGetHeight(videoPlay.bounds));
    [videoPlay addSubview:aView];
    // 这两行代码使为了让aView随着videoPlay的变化而变化
    aView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    aView.contentMode = UIViewContentModeScaleAspectFit;
    // 让播放视频视图处于控制视图下方
    [videoPlay sendSubviewToBack:aView];

需要实现的代理：

- (void)videoPlayerControlDidCloseClick:(HFVideoPlayerControlView *)videoPlayerController {
    NSLog(@"关闭");
}
- (void)videoPlayerControlDidPlayClick:(HFVideoPlayerControlView *)videoPlayerController {
    NSLog(@"播放");
}
- (void)videoPlayerControlDidPauseClick:(HFVideoPlayerControlView *)videoPlayerController {
    NSLog(@"暂停");
}
- (void)videoPlayerControlDidEnterFullScreenClick:(HFVideoPlayerControlView *)videoPlayerController {
    NSLog(@"进入全屏");
}
- (void)videoPlayerControlDidShrinkFullScreenClick:(HFVideoPlayerControlView *)videoPlayerController {
    NSLog(@"取消全屏");
}
- (void)videoPlayerControlDidChangeProgressValue:(HFVideoPlayerControlView *)videoPlayerController {
    NSLog(@"改变进度");
}

注意事项：
状态栏旋转的方法使用的是[[UIApplication sharedApplication] setStatusBarOrientation:(UIInterfaceOrientationLandscapeRight) animated:YES];
以下两个注意事项都是为了让状态栏能够旋转方向而设置。
①：需在info.plist中配置View controller-based status bar appearance的属性设置为NO
②：需在播放视频的控制器中重写shouldAutorotate方法，并返回NO：

- (BOOL)shouldAutorotate {
    return NO;
}

更新：

解决当前播放器的控制器是受导航控制器UINavigationController控制的时候状态栏无法旋转的问题。

增加两个对外接口方法- (void)showInWindow;和- (void)showInView:(UIView *)view;分别在进入全屏和取消全屏的时候调用，进行切换全屏和小屏的切换。
然后，导航控制器UINavigationController添加一个分类，实现下面三个方法：

#import "UINavigationController+Orientation.h"

@implementation UINavigationController (Orientation)

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


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


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