Fade in and fade out animation is too slow - ios

Question

I made an animation, fade in and fade out on a cell. When I press the cell(a button on the entire cell) the action is delegate via a protocol on a collectionView and pops to another controller (detailController).
The cell
- (IBAction)cellButtonPressed:(id)sender {
[self fadeIn];
}
-(void)fadeIn {
[UIView animateWithDuration:0.5
delay:0.0
options:0.0
animations:^{
self.coverAlbumPhoto.alpha = 0.0f;
self.shadowView.alpha = 0.0f;
self.mountainBorderImageView.alpha = 0.0f;
} completion:^(BOOL finished) {
[self fadeOut];
}];
}
-(void)fadeOut {
[UIView animateWithDuration:0.5
delay:0.0
options:0.0
animations:^{
self.coverAlbumPhoto.alpha = 1.0f;
self.shadowView.alpha = 1.0f;
self.mountainBorderImageView.alpha = 1.0f;
} completion:^(BOOL finished) {
if ([self.delegate respondsToSelector:#selector(tapCellButtonAtIndexPath:)]) {
[self.delegate tapCellButtonAtIndexPath:self.indexPath];
}
}];
}
Collection View
(void)tapCellButtonAtIndexPath:(NSIndexPath *)indexPath {
ArtworkModel *artworkModel = (ArtworkModel *)[listOfArtworks objectAtIndex:indexPath.row];
FBWorkDetailsViewController *dvc = [[FBWorkDetailsViewController alloc] initWithArtwork:artworkModel];
FBLeftMenuViewController *left = [[FBLeftMenuViewController alloc] init];
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController: dvc
leftMenuViewController: left
rightMenuViewController:nil
withHeader: YES];
[container.titleLabel setText:#"WORK DETAILS"];
[self.navigationController pushViewController: container animated: YES];
}
The problem is that the animation is TOO SLOW. Can anybody explain me why? Thanks.

Answer 1

You have 2 animations, each with a duration of .5 seconds. That gives a total duration of 1 second. If you want it to be faster, use shorter durations. A total animation time of .2 to .3 seconds is probably a good place to start, so try backing down the duration of each step to 0.15 seconds (0.3 seconds total).
