AVPlayer按特定时间跳过

你只需要做几个简单的数学步骤,在Swift 3中应该是这样的:

private func skipBy(percentage: Float64) {

    guard let durationTime = player.currentItem?.duration else { return }

    // Percentage of duration
    let percentageTime = CMTimeMultiplyByFloat64(durationTime, percentage)

    guard percentageTime.isValid && percentageTime.isNumeric else { return }

    // Percentage plust current time
    var targetTime = player.currentTime() + percentageTime
    targetTime = targetTime.convertScale(durationTime.timescale, method: .default)

    // Sanity checks
    guard targetTime.isValid && targetTime.isNumeric else { return }

    if targetTime > durationTime {
        targetTime = durationTime // seek to end
    }

    player.seek(to: targetTime)
}
