How can I add 5 seconds to my current playing Time?
Actually this is my code:
CMTime currentTime = music.currentTime;
I can´t use CMTimeGetSeconds() , because I need the CMTime format.
Thank you for your answers...
EDIT: How can I set a variable for CMTime?
Here is one way:
CMTimeMakeWithSeconds(CMTimeGetSeconds(music.currentTime) + 5, music.currentTime.timescale);
elegant way is using CMTimeAdd
CMTime currentTime = music.currentTime;
CMTime timeToAdd = CMTimeMakeWithSeconds(5,1);
CMTime resultTime = CMTimeAdd(currentTime,timeToAdd);
//then hopefully
[music seekToTime:resultTime];
to your edit: you can create CMTime struct by these ways
CMTimeMake
CMTimeMakeFromDictionary
CMTimeMakeWithEpoch
CMTimeMakeWithSeconds

In Swift:
private extension CMTime {
func timeWithOffset(offset: TimeInterval) -> CMTime {
let seconds = CMTimeGetSeconds(self)
let secondsWithOffset = seconds + offset
return CMTimeMakeWithSeconds(secondsWithOffset, preferredTimescale: timescale)
}
}
Swift 4, using custom operator:
extension CMTime {
static func + (lhs: CMTime, rhs: TimeInterval) -> CMTime {
return CMTime(seconds: lhs.seconds + rhs,
preferredTimescale: lhs.timescale)
}
static func += (lhs: inout CMTime, rhs: TimeInterval) {
lhs = CMTime(seconds: lhs.seconds + rhs,
preferredTimescale: lhs.timescale)
}
}
