Question

我有一个TableView，在UITableViewCell中我有一个UICollectionView。现在在我的collectionView中，对于每个collectionViewCell，都有一个创建单元格和删除单元格按钮选项。因此，对于创建单元格，我必须使用CreateViewController，对于删除按钮，我必须删除各自的collectionViewCell。

import UIKit

class TableCollectionCell: UITableViewCell {

@IBOutlet weak var collectionView: UICollectionView!

override func awakeFromNib() {
    super.awakeFromNib()

    //collectionView cell
    collectionView!.register(UINib(nibName: "CreateGroupCell", bundle: nil), forCellWithReuseIdentifier: "CreateGroupCell")
}

override func setSelected(_ selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

}
}

//Collection View
extension TableCollectionCell : UICollectionViewDataSource ,UICollectionViewDelegateFlowLayout
{
 func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
 {
    return 4
 }

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CreateGroupCell", for: indexPath) as! CreateGroupCell

    cell.groupName.text = ""
    CreateCardView(viewCorner: cell.cardView)

    if(0 == indexPath.row)
    {
        //cell.btnDotted.tag = indexPath.row
        //cell.btnShare.tag = indexPath.row
        cell.btnDotted.setImage(UIImage(named: "Info"), for: UIControlState.normal)
        cell.btnShare.setImage(UIImage(named : "AddGroup"), for: UIControlState.normal)
    }

    else if(indexPath.row >= 1 && indexPath.row <= 3)
    {
        cell.btnDotted.isHidden = true
        cell.btnShare.isHidden = true
        cell.groupImage.image = UIImage(named: "group_dull_card.png")
    }

    else
    {

    }

    return cell
}


func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    if ( 0 == indexPath.row) {


    }
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {

    return CGSize(width: 200, height: 150)
}
}

现在在我的didSelectRow方法if（indexPath.row == 0）然后我必须去CreateViewController。

我该怎么做？我也是代表的新人。

didSelectRow方法

ViewPager viewPager;
ViewPagerAdapter adapter;


viewPager = (ViewPager) findViewById(R.id.tabanim_viewpager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabanim_tabs);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabanim_tabs);
setupViewPager(viewPager);
tabLayout.setupWithViewPager(viewPager);


viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        @Override
        public void onPageSelected(int position) {
            adapter.getItem(position).onResume();
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {
        }

        @Override
        public void onPageScrollStateChanged(int arg0) {
        }
    });


public void setupViewPager(ViewPager upViewPager) {
    adapter = new ViewPagerAdapter(getSupportFragmentManager());
    adapter.addFrag(new ViewTodayFragment(),"Daily");
    adapter.addFrag(new ViewWeekFragment(),"Weekly");
    adapter.addFrag(new ViewMonthFragment(),"Monthly");
    adapter.addFrag(new ViewYearFragment(),"Yearly");
    viewPager.setAdapter(adapter);
}

如何使用集合查看单元格查看下一个视图？
