ios - UICollectionView 单元格之间的距离不变

Question

我正在开发 iOS 应用程序，但我曾一度陷入困境。

我正在使用水平collectionView，我想减少两个collectionViewCell之间的间距，我已经编写了下面的代码片段，但它不会改变之间的间距细胞。

.h 类

@property(强，非原子)IBOutlet UICollectionView *CollectnVw;

.m 类

- (void)viewDidLoad{
   [_CollectnVw registerNib:[UINib nibWithNibName:@"FilterCustomCell" bundle:nil] forCellWithReuseIdentifier:@"collectionViewCell"];
    _CollectnVw.backgroundColor = [UIColor clearColor];

    UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];
    [flowLayout setItemSize:CGSizeMake(100, 35)];
    [flowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal];
    [_CollectnVw setCollectionViewLayout:flowLayout];
    [_CollectnVw setAllowsSelection:YES];
    _CollectnVw.delegate=self;

}

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
    return [FilterNameArr count];
}

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

    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"collectionViewCell" forIndexPath:indexPath];
    UILabel *titleLabel = (UILabel *)[cell viewWithTag:96];
    [titleLabel setText:[FilterNameArr objectAtIndex:indexPath.row]];

    cell.layer.borderWidth=1.0f;
    cell.layer.borderColor=[UIColor blueColor].CGColor;
    return cell;
}


- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionView *)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section
{
    return 50; // This is the minimum inter item spacing, Doesn't changing.....
}

我能够看到我的单元格，但单元格之间的间距没有改变，我希望单元格之间的间距为零...

请帮助并提前致谢

写到这里终于解决了问题，

flowLayout.minimumInteritemSpacing=0.0f;
flowLayout.minimumLineSpacing=0.0f;
