iOS:一次滚动一个单元格

Question

我现在设置了水平滚动我希望它能够一次滚动/捕捉一个单元格,同时滚动到一边.

有人能解开一些光吗？这是我到目前为止的代码:

- (void)viewDidLoad
{
    [super viewDidLoad];
}

#pragma mark - UICollectionView Datasource

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return 1;
}

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return 20;
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    MyCell *cell = [cv dequeueReusableCellWithReuseIdentifier:@"MyCell" forIndexPath:indexPath];
    cell.backgroundColor = [UIColor whiteColor];
    return cell;
}

#pragma mark - UICollectionViewDelegateFlowLayout

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
    return UIEdgeInsetsMake(50, 20, 50, 20);
}

Answer 1

[collectionView setPagingEnabled:YES]; 可能会做的伎俩？
