如何在Objective-C iOS中的AVPlayerViewController上添加自定义按钮？

Question

我想在AVPlayerViewController中添加一个按钮，但是我无法做到这一点。我添加了一个按钮[AVPlayerViewController.contentOverlayView addSubview:_btnHandfree];，但它不可点击，这是屏幕截图

也许在其中找不到上层。

尝试这个。可能会有帮助。

#import "ViewController.h"
#import <AVKit/AVKit.h>

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.


}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];


    NSURL *url=[[NSBundle mainBundle]URLForResource:@"videoplayback" withExtension:@"mov"];
    AVPlayer *player = [AVPlayer playerWithURL:url];
    AVPlayerViewController *playerViewController = [AVPlayerViewController new];
    playerViewController.player = player;

    UIButton *button = [[UIButton alloc] initWithFrame: CGRectMake(20, 100, 100, 50)];
    [button addTarget:self
               action:@selector(aMethod:) forControlEvents:UIControlEventTouchDown];

    [button setTitle:@"Button" forState:UIControlStateNormal];
    [button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
    [button setBackgroundColor:[UIColor whiteColor]];

    [self presentViewController:playerViewController animated:YES completion:^{
      [playerViewController.player play];
    }];
    [self.player addSubview:playerViewController.view];
    [self.view addSubview:button];

    for(UIWindow* tempWindow in [[UIApplication sharedApplication]windows]){
        for(UIView* tempView in [tempWindow subviews]){

            if ([[tempView description] rangeOfString:@"UIInputSetContainerView"].location != NSNotFound){
                [tempView addSubview:button];

                break;
            }
        }
    }
}

-(void)aMethod:(UIButton*)sender {
    NSLog(@"test");
}


@end

如Apple文档中所述。

显示在视频内容和播放控件之间的视图。

您可以调试视图层次结构以查看按钮在堆栈中的位置。

那么，如果直接将其添加到视图中呢？

[AVPlayerViewController.view addSubview:yourButton];
