我正在使用 ScrollView 。在我的 ScrollView 中有收藏 View 。我的收藏 View 最后 3 个元素隐藏在空白区域中。在滚动 ScrollView 时，它们不显示。它们在滚动 CollectionView 时显示。我想在 Scroll ScrollView 上显示所有 Collection Cell。不滚动 CollectionView。
-(NSInteger)numberOfSectionsInCollectionView:
(UICollectionView *)collectionView {
return 1; // The number of sections we want
}
-(NSInteger)collectionView:(UICollectionView *)collectionView
numberOfItemsInSection:(NSInteger)section {
return 5; // the number of cells we want
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionViewd
cellForItemAtIndexPath:(NSIndexPath *)indexPath {
CollectionCell* cell =
[collectionViewd dequeueReusableCellWithReuseIdentifier:@"collectionView2CellIdentifier"
forIndexPath:indexPath]; // Create the cell from the storyboard cell
cell.layer.cornerRadius = 4;
cell.layer.borderWidth = 1;
cell.layer.borderColor = [UIColor grayColor].CGColor;
cell.yellow.layer.cornerRadius=4;
cell.red.layer.cornerRadius=4;
cell.title.text =[titleArray objectAtIndex:indexPath.row];
cell.date.text =[dateArray objectAtIndex:indexPath.row];
cell.incomeText.text =[netIncomeArray objectAtIndex:indexPath.row];
cell.expenseText.text =[netExpenseArray objectAtIndex:indexPath.row];
cell.saving.text =[savingArray objectAtIndex:indexPath.row];
cell.expensePecentageText.text =[expensePercentage objectAtIndex:indexPath.row];
cell.savingPercentage.text =[netProfitPercentage objectAtIndex:indexPath.row];
return cell; // Return the cell
}
- (CGFloat)collectionView:(UICollectionView *) collectionView
layout:(UICollectionViewLayout *) collectionViewLayout
minimumInteritemSpacingForSectionAtIndex:(NSInteger) section {
return 2.0;
}
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
{
return UIEdgeInsetsMake(2, 2, 2, 2);
}
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
return CGSizeMake(155, 158);
}
[scrollView setContentSize:CGSizeMake(0, expenseButton.frame.origin.y+expenseButton.frame.size.height+collection.frame.size.height+16)];
最佳答案
首先统计collectionview的高度 By :
例如
titleArray.count * 160(158px 单元格高度 + 2px 单元格间距)
然后将这个高度分配给collectionview frame
还将此分配给 ScrollView 内容大小高度。
这肯定会为您解决问题。
