I am creating an audio player application, i need to enable the user to fast forward and backward a song by holding a button(seperately for each). I've done for playing, stopping, skip to next and previous song. But i got stuck with this section. I dont know the method to implement this. pls help.
Use the currentTime
and duration
properties.
ie to skip forward
NSTimeInterval time = avPlayer.currentTime;
time += 5.0; // forward 5 secs
if (time > avPLayer.duration)
{
// stop, track skip or whatever you want
}
else
avPLayer.currentTime = time;
Similar for going backwards, only compare currentTime
against 0
, instead of duration
In swift 4
for forward
var timeForward = audioPlayer.currentTime
timeForward += 10.0 // forward 10 secs
if (timeForward > audioPlayer.duration) {
audioPlayer.currentTime = timeForward
} else {
audioPlayer.currentTime = audioPlayer.duration
}
for backward
var timeBack = audioPlayer.currentTime
timeBack -= 10.0 //backward 10 secs
if (timeBack > 0) {
audioPlayer.currentTime = timeBack
} else {
audioPlayer.currentTime = 0
}
Hope this will help.
