Question

在tvOS上，如果我想允许播放/暂停但禁止搜索，则可以设置avPlayerViewController.requiresLinearPlayback = YES。但是，此属性在iOS中不存在。我将如何在iOS上完成相同的任务？我不想使用avPlayerViewController.showsPlaybackControls = NO，因为这会阻止播放/暂停。我仅要禁用搜索。此外，我不确定avPlayerViewController.showsPlaybackControls = NO会完全阻止搜索，因为有人可以插入带有控制按钮的头戴式耳机并按下物理“向前跳过”按钮

我通过扩展AVPlayer解决了这个问题。尽管Apple文档说您不应该不扩展AVPlayer并且这样做具有不确定的行为，但是在测试中，一切在iOS 9到13上都可以正常工作

@interface CustomAVPlayer : AVPlayer

@property BOOL seekingEnabled;

@end

@implementation CustomAVPlayer

- (instancetype)initWithPlayerItem:(AVPlayerItem *)item
{
    self = [super initWithPlayerItem:item];
    if (self) {
        _seekingEnabled = YES;
    }
    return self;
}

- (void)seekToTime:(CMTime)time toleranceBefore:(CMTime)toleranceBefore toleranceAfter:(CMTime)toleranceAfter completionHandler:(void (^)(BOOL))completionHandler
{
    // This prevents seeking at the lowest level, regardless of whatever shenanigans the view may be doing
    if (_seekingEnabled)
        [super seekToTime:time toleranceBefore:toleranceBefore toleranceAfter:toleranceAfter completionHandler:completionHandler];
    else
        [super seekToTime:self.currentTime toleranceBefore:toleranceBefore toleranceAfter:toleranceAfter completionHandler:completionHandler];
}

@end

现在，我可以仅使用player.seekingEnabled = (YES/NO);

启用/禁用搜索

如何在iOS AVPlayerViewController上禁用搜索？
