我创建了一个UICollectionView视图，其中我给出了类似iOS的弹簧板的效果。当我长按UICollectionView时，他们就会开始制作动画片。它工作正常。现在，当我长时间按下牢房和动画开始然后我想移动不同位置的细胞＆amp;保持它，直到下次我改变它。请告诉我怎么做到这一点？
这是我的细胞动画代码
- (void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
if (gestureRecognizer.state != UIGestureRecognizerStateEnded) {
return;
}
p = [gestureRecognizer locationInView:self.collection_view];
NSIndexPath *indexPath = [self.collection_view indexPathForItemAtPoint:p];
if (indexPath == nil) {
NSLog(@"couldn't find index path");
}
else {
[[NSUserDefaults standardUserDefaults]setValue:@"yes" forKey:@"longPressed"];
[self.collection_view reloadData];
}
}
CellForItem
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(@"arr_album index row");
BlogAlbumCell *cell;
static NSString *identifier = @"UserBlogAlbum";
cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
UserAlbum *user_allbum=[arr_userAlbums objectAtIndex:indexPath.row];
cell.label_blog_name.text=user_allbum.album_name;
cell.image_blog_image.image = [UIImage imageNamed:@"more.png"];
[cell.image_blog_image setImageWithURL:[NSURL URLWithString:[IMAGE_BASE_URL stringByAppendingString:user_allbum.album_image]]];
if([[[NSUserDefaults standardUserDefaults]valueForKey:@"longPressed"] isEqualToString:@"yes"])
{
CABasicAnimation* anim = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
[anim setToValue:[NSNumber numberWithFloat:0.0f]];
[anim setFromValue:[NSNumber numberWithDouble:M_PI/50]];
[anim setDuration:0.1];
[anim setRepeatCount:NSUIntegerMax];
[anim setAutoreverses:YES];
cell.layer.shouldRasterize = YES;
[cell.layer addAnimation:anim forKey:@"SpringboardShake"];
CGFloat delButtonSize = 20;
UIButton *delButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, delButtonSize, delButtonSize)];
delButton.center = CGPointMake(9, 10);
delButton.backgroundColor = [UIColor clearColor];
[delButton setImage: [UIImage imageNamed:@"cross_30.png"] forState:UIControlStateNormal];
[cell addSubview:delButton];
[delButton addTarget:self action:@selector(deleteRecipe:) forControlEvents:UIControlEventTouchUpInside];
}
else if ([[[NSUserDefaults standardUserDefaults]valueForKey:@"singleTap"] isEqualToString:@"yes"])
{
for(UIView *subview in [cell subviews])
{
if([subview isKindOfClass:[UIButton class]])
{
[subview removeFromSuperview];
}
else
{
// Do nothing - not a UIButton or subclass instance
}
}
[cell.layer removeAllAnimations];
// _deleteButton.hidden = YES;
// [_deleteButton removeFromSuperview];
}
return cell;
}
