我有这个班级
class HomePage: UIViewController,UICollectionViewDataSource, UICollectionViewDelegateFlowLayout, UICollectionViewDelegate
在本课程中,我有很多UIViews.One是tabView
。现在我想将collectionView
添加到tabView
的底部,我该怎么做?这是我的`collectionView
var flowLayout = UICollectionViewFlowLayout()
let collectionView = UICollectionView(frame: CGRect(x:0,y:500,width:self.view.frame.size.width,height:100 ), collectionViewLayout: flowLayout)
collectionView.register(UICollectionViewCell.self, forCellWithReuseIdentifier: cellId)
collectionView.delegate = self
collectionView.dataSource = self
collectionView.backgroundColor = .red`
和tabView
tabView.topAnchor.constraint(equalTo: profileInfWrapper.bottomAnchor).isActive = true
tabView.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true
tabView.widthAnchor.constraint(equalToConstant: UIScreen.main.bounds.size.width/4).isActive = true
tabView.heightAnchor.constraint(equalToConstant: 80).isActive = true
答案 0 :(得分:2)
您可以在tabView和设置约束中添加collectionView:
collectionView.translatesAutoresizingMaskIntoConstraints = false
tabView.addSubview(collectionView)
collectionView.topAnchor.constraint(equalTo: tabView.topAnchor, constant: 20).isActive = true
....并添加其他约束
或者您可以在标签视图下添加它,如下所示:
self.view.addSubview(collectionView)
collectionView.topAnchor.constraint(equalTo: tabView.bottomAnchor, constant: 20).isActive = true

顺便说一句,你可以这样设置tabView的宽度:
tabView.widthAnchor.constraint(equalTo: self.view.widthAnchor, multiplier: 0.25).isActive = true
