如何从UIButton打开UITableView

Question

我正在使用具有许多单元格的自定义UICollectionView，每个单元格的底部附近都有一个按钮。 我想要做的是单击给定的单元格按钮时显示一个数字列表。 表列表将是简单的数字列表[1-n]，其中n在单元的indexPath（即节和行）上变化。

我想弄清楚的是：

1）每当单击给定单元格的按钮时，如何打开uitableview？ 2）我打开的uitableview是否必须占据整个屏幕？

基本上我不希望它占据整个屏幕（因为我被锁定在“风景”模式下，这看起来很奇怪），所以我想知道如何控制tableView的宽度和高度？

对不起，对于新手iOS问题，非常感谢！

（ flipScore按钮是我要从中打开uitableview的位置

-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
    return 4;
}

-(NSInteger)collectionView:(UICollectionView *)collectionView
    numberOfItemsInSection:(NSInteger)section
{
    return _scoresList.count;
}

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    MainCollectionViewCell *cell = [collectionView
                                      dequeueReusableCellWithReuseIdentifier:@"ScoreCell"
                                      forIndexPath:indexPath];

    cell.layer.borderWidth=1.5f;
    cell.layer.borderColor=[UIColor whiteColor].CGColor;

    [[cell flipScore] addTarget:self action:@selector(flipScore:event:) forControlEvents:UIControlEventTouchUpInside];

    long row = [indexPath row];
    NSString *score;
    NSInteger scoreVal;

            if (scoreVal < 0) {
                // if score negative, player did not make that hand
                [cell.flipScore setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

Answer 1

UITableView不需要占用整个屏幕。 您可以设置表格视图的框架，并根据是否要显示它来设置hidden = YES或=NO 。

Answer 2

您可以使用KGModal 。 您可以使用UITableViewController向您显示数据，然后使用

- (void)showWithContentViewController:(UIViewController *)contentViewController andAnimated:(BOOL)animated;

也不必担心方向，KGModal足够聪明，可以为您处理：)

希望这会起作用。
