Question

最终结果是在旋转设备后调整cell.title和cell.description的大小，使其填满整个屏幕。这个collectionviewcontroller在Viewcontroller中，所以我需要一个特定于细胞的解决方案。

- (UICollectionViewCell *) collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{


  if(collectionView == collection1)
  {


SliderCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"articleCellslider1"
                                                                           forIndexPath:indexPath];

NSDictionary *item = [_articleListslider objectAtIndex:indexPath.item];

// set the article image
[cell.image setImageWithURL:[item objectForKey:@"image"]];

// set the text of title UILabel
cell.title.text = [NSString stringWithFormat:@"%@\n\n\n\n", [item objectForKey:@"title"]];
cell.title.textColor = [UIColor colorWithRed:33.0f/255.0f green:74.0f/255.0f blue:146.0f/255.0f alpha:1.0f];
cell.title.backgroundColor = [UIColor colorWithRed:255.0f/255.0f green:255.0f/255.0f blue:255.0f/255.0f alpha:0.5f];

// set the text of summary UILabel
cell.description.text = [NSString stringWithFormat:@"%@\n\n\n\n\n\n\n\n\n", [item objectForKey:@"description"]];
cell.description.font = [UIFont fontWithName:@"Helvetica Neue" size:14];
cell.description.backgroundColor = [UIColor colorWithRed:255.0f/255.0f green:255.0f/255.0f blue:255.0f/255.0f alpha:0.5f];

cell.targetURL = [item objectForKey:@"link"];

cell.sliderphoto = [item objectForKey:@"sliderphoto"];

cell.date.text = [NSString stringWithFormat:@"%@\n\n\n\n", [item objectForKey:@"pubDate"]];

cell.category.text = [NSString stringWithFormat:@"%@\n\n\n\n", [item objectForKey:@"category"]];


return cell;

[self performSegueWithIdentifier:@"Slider" sender:indexPath];



}

我希望在旋转时特别调整大小的单元格是cell.title和cell.description

覆盖其中一个旋转UIviewController委托方法，尝试willRotateToInterfaceOrientation（可能做了而不是更好）然后当你抓住它时，重新加载你的表视图并设置一些标志以知道它被旋转。

然后实现UICollectionViewDelegateFlowLayout，collectionView：layout：sizeForItemAtIndexPath：（根据方向在这里改变大小）

如何在旋转时为UICollectionView调整特定单元格的大小？
