AVPlayer - Add Seconds to CMTime

Question

How can I add 5 seconds to my current playing Time?
Actually this is my code:

CMTime currentTime = music.currentTime;

I can´t use CMTimeGet

Answer 1

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
