为 UICollectionView 指定行号和列号 [英] Specify row and column number for UICollectionView

问题描述

我想展示一个 UICollectionView，它正好包含 2 行，每行 100 个单元格.

I want to show a UICollectionView which contains exactly 2 rows and 100 cells in each row.

// 1
- (NSInteger)collectionView:(UICollectionView *)view numberOfItemsInSection:(NSInteger)section {

    return 100;
}
// 2
- (NSInteger)numberOfSectionsInCollectionView: (UICollectionView *)collectionView {
    return 2;
}
// 3
- (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    MyCell *cell = [cv dequeueReusableCellWithReuseIdentifier:@"cell" forIndexPath:indexPath];

        cell.lbl.text = @"Data";

    return cell;
}

我得到了这个:
