I want to add uislider to my player so that i can implement scrubbing while playing audio in AVPlayer . as soon as the first song gets played out the uislider will go back to original position and the next song will start playing . If anyone help me i would appreciate it .This is my code.
-(IBAction)goToiPodLibrary:(UIButton *)sender
{
// Create picker view
MPMediaPickerController* picker = [[MPMediaPickerController alloc] init];
picker.delegate = self;
if (userMediaItemCollection) {
MusicTableViewController *controller = [[MusicTableViewController alloc] initWithNibName: @"MusicTableView" bundle: nil];
controller.delegate = self;
controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController: controller animated: YES];
// else, if no music is chosen yet, display the media item picker
} else {
MPMediaPickerController *picker =
[[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic];
picker.delegate = self;
picker.allowsPickingMultipleItems = YES;
picker.prompt = NSLocalizedString (@"Add songs to play", "Prompt in media item picker");
// The media item picker uses the default UI style, so it needs a default-style
// status bar to match it visually
[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES];
[self presentModalViewController: picker animated: YES];
}
}
-(IBAction)playButtonPressed:(UIButton *)sender
{
[myPlayer play];
}
-(IBAction)pauseButtonPressed:(UIButton *)sender
{
[myPlayer pause];
}
-(void) mediaPickerDidCancel:(MPMediaPickerController *)mediaPicker {
// Dismiss selection view
[self dismissViewControllerAnimated:YES completion:nil];
}
-(void) mediaPicker:(MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection {
// Dismiss selection view
[self dismissViewControllerAnimated:YES completion:nil];
// Get AVAsset
NSURL* assetUrl = [mediaItemCollection.representativeItem valueForProperty:MPMediaItemPropertyAssetURL];
AVURLAsset* asset = [AVURLAsset URLAssetWithURL:assetUrl options:nil];
// Create player item
AVPlayerItem* playerItem = [AVPlayerItem playerItemWithAsset:asset];
// Play it
myPlayer = [AVPlayer playerWithPlayerItem:playerItem];
[playlistSongsArray addObjectsFromArray:mediaItemCollection.items];
NSLog(@" Playlist songs %@",playlistSongsArray);
[self.myPlaylistTable reloadData];
[myPlayer play];
}
- (void)sliderValueChanged:(id)sender {
CMTime newTime = CMTimeMakeWithSeconds(timeSlider.value * durationSeconds, player.currentTime.timescale);
[self.player seekToTime:newTime];
}
Use a UISlider
(here called timeSlider) and the method above
This is how to update slider when playing:
self.playbackObserver = [player addPeriodicTimeObserverForInterval:interval queue:NULL usingBlock:^(CMTime time) {
CMTime endTime = CMTimeConvertScale (player.currentItem.asset.duration, player.currentTime.timescale, kCMTimeRoundingMethod_RoundHalfAwayFromZero);
if (CMTimeCompare(endTime, kCMTimeZero) != 0) {
double normalizedTime = (double) player.currentTime.value / (double) endTime.value;
self.timeSlider.value = normalizedTime;
}
Float64 currentSeconds = CMTimeGetSeconds(player.currentTime);
int mins = currentSeconds/60.0;
int secs = fmodf(currentSeconds, 60.0);
NSString *minsString = mins < 10 ? [NSString stringWithFormat:@"0%d", mins] : [NSString stringWithFormat:@"%d", mins];
NSString *secsString = secs < 10 ? [NSString stringWithFormat:@"0%d", secs] : [NSString stringWithFormat:@"%d", secs];
currentTimeLabel.text = [NSString stringWithFormat:@"%@:%@", minsString, secsString];
}];
I have made my own player for playing video. Here is code for UISlider
i have made. Initialize the UISlider
self.progressBar = [[[UISlider alloc] init] autorelease];
self.progressBar.frame = CGRectMake(44*frameWidth/240, 6*frameHeight/160, 187*frameWidth/240,33*frameHeight/160);
[self.progressBar addTarget:self action:@selector(progressBarChanged:) forControlEvents:UIControlEventValueChanged];
[self.progressBar addTarget:self action:@selector(proressBarChangeEnded:) forControlEvents:UIControlEventTouchUpInside];
[self.progressBar setThumbImage:[UIImage imageNamed:@"Slider_button"] forState:UIControlStateNormal];
[self.playerManageViewBottom addSubview:self.progressBar];
Now add an observer and the functions.
CMTime interval = CMTimeMake(33, 1000);
playbackObserver = [self.moviePlayer addPeriodicTimeObserverForInterval:interval queue:dispatch_get_current_queue() usingBlock: ^(CMTime time) {
CMTime endTime = CMTimeConvertScale (self.moviePlayer.currentItem.asset.duration, self.moviePlayer.currentTime.timescale, kCMTimeRoundingMethod_RoundHalfAwayFromZero);
if (CMTimeCompare(endTime, kCMTimeZero) != 0) {
double normalizedTime = (double) self.moviePlayer.currentTime.value / (double) endTime.value;
self.progressBar.value = normalizedTime;
}
self.playBackTime.text = [self getStringFromCMTime:self.moviePlayer.currentTime];
}];
Functions :
-(void)progressBarChanged:(UISlider*)sender
{
if (self.isPlaying) {
[self.moviePlayer pause];
}
CMTime seekTime = CMTimeMakeWithSeconds(sender.value * (double)self.moviePlayer.currentItem.asset.duration.value/(double)self.moviePlayer.currentItem.asset.duration.timescale, self.moviePlayer.currentTime.timescale);
[self.moviePlayer seekToTime:seekTime];
}
-(void)proressBarChangeEnded:(UISlider*)sender { if (self.isPlaying) { [self.moviePlayer play]; } }
Hope it can help you.
I tried the top solution, and for longer videos this was okay, but when I had a ~4 second video, the UISlider was very choppy. If you want precision, try this solution:
- (IBAction)sliderSlid:(id)sender {
if ([sender isKindOfClass:[UISlider class]]) {
UISlider *slider = sender;
CMTime playerDuration = player.currentItem.duration;
if (CMTIME_IS_INVALID(playerDuration)) {
return;
}
double duration = CMTimeGetSeconds(playerDuration);
if (isfinite(duration)) {
float minValue = [slider minimumValue];
float maxValue = [slider maximumValue];
float value = [slider value];
double time = duration * (value - minValue) / (maxValue - minValue);
[player seekToTime:CMTimeMakeWithSeconds(time, NSEC_PER_SEC) toleranceBefore:kCMTimeZero toleranceAfter:kCMTimeZero];
}
[player pause];
}
}
This My code is Online Play the Audio Song with Volume slider. You can easily increase and decrease the volume.Using AvAudioPlayer...
