collectionView didSelectItemAtIndexPath with sending images
我正在收藏视图中显示图像。当我选择特定单元格时,详细图像将显示在另一个视图控制器中。委托方法是 didSelectItemAtIndexPath。请帮帮我。
1 2 3 4 5 6 7 8 9 10 11 12 | recipeImages = [NSArray arrayWithObjects:@"img2.png", @"img.png", @"img1.png", @"img3.png", @"img4.png", @"img5.png", @"img6.png", @"img7.png", nil]; - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView1 cellForItemAtIndexPath:(NSIndexPath *)indexPath{ static NSString *identifier = @"Cell"; CustomCell *cell = (CustomCell *)[collectionView1 dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath]; [cell.imageView setImage:[UIImage imageNamed:[recipeImages objectAtIndex:indexPath.row]]]; return cell; } |
检查以下代码:
1 2 3 4 5 6 7 8 | - (void)collectionView:(UICollectionViewCell *)collectionView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { DetailViewController *detailVC = [[DetailViewController alloc] initWithNibName:@"MyCell" bundle:[NSBundle mainBundle]]; detailVC.img= [recipeImages objectAtIndex: indexPath.row]; [self presentViewController:detailVC animated:YES completion:nil]; } |
检查以下代码:
1 2 3 4 5 6 7 8 9 | - (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath { NSString *senderImg=[recipeImages objectAtIndex:indexPath.item]; NextViewController *next = [[NextViewController alloc] initWithNibName:@"NextViewController" bundle:nil]; next.receivedImage=senderImg; [self presentModalViewController:next animated:NO]; } |
NextViewController.h
1 | @property(nonatomic,retain)NSString *receivedImage; |
NextViewController.m
1 2 3 4 5 6 | @syntosize receivedImage; -(void)viewDidLoad { UIImage imageDispay=[UIImage imageNamed:receivedImage]; } |
