創建2 UICollectionView類collectionviewCell不會改變，每一個使用2個不同的UICollectionViewCell當過渡到其它collectionviewController
@interface PhotosCollectionViewController : UICollectionViewController
@interface FullScreenCollectionViewController : UICollectionViewController
@interface PhotoCell : UICollectionViewCell
@interface FullPhotoCell : UICollectionViewCell<UIScrollViewDelegate>
在PhotosCollectionViewController.m，我寄存器光電管類，然後選擇下一個視圖控制器FullScreenCollectionViewController當didSelect
//Register Cell
-(id)initWithCollectionViewLayout:(UICollectionViewFlowLayout *)layout{
if (self = [super initWithCollectionViewLayout:layout])
{
[self.collectionView registerClass:[PhotoCell class] forCellWithReuseIdentifier:CELL_ID];
}
return self;
}
//dequence resuse code
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
PhotoCell* cell = (PhotoCell *)[collectionView dequeueReusableCellWithReuseIdentifier:CELL_ID forIndexPath:indexPath];
NSLog(@"reuse CELL");
FICDPhoto *photo = [_photos objectAtIndex:indexPath.row];
cell.imageView.image = [photo sourceImage];
return cell;
}
//Next ViewController transition code
-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
UIViewController *vc = [self nextViewControllerAtPoint:CGPointZero];
[self.navigationController pushViewController:vc animated:YES];
}
-(UICollectionViewController*)nextViewControllerAtPoint:(CGPoint)p
{
FullScreenCollectionViewController* nextCollectionViewController = [[FullScreenCollectionViewController alloc] initWithCollectionViewLayout:[[FullScreenFlowLayout alloc] init]];
nextCollectionViewController.useLayoutToLayoutNavigationTransitions = YES;
nextCollectionViewController.title = @"FullScreen";
return nextCollectionViewController;
}
在FullScreenCollectionViewController，我註冊FullPho toCell類
[self.collectionView registerClass:[FullPhotoCell class] forCellWithReuseIdentifier:CELL_ID_FULL];
但是序列代碼永遠不會調用
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
FullPhotoCell* cell = (FullPhotoCell *)[collectionView dequeueReusableCellWithReuseIdentifier:CELL_ID_FULL forIndexPath:indexPath];
NSLog(@"Reuse FULL Cell");
FICDPhoto *photo = [_photos objectAtIndex:indexPath.row];
cell.imageView.image = [photo sourceImage];
return cell;
}
新的佈局是適用，FullScreenCollectionViewController的viewDidLoad中也呼籲，但日誌消息「複用小區」告訴全屏的CollectionView仍然使用舊的光電類。
我還是不明白是什麼問題。請幫幫我！
