搜索栏消失SWIFT 5

Question

我在搜索页面上有一个搜索栏。搜索栏可以正常工作，但我想通过在搜索页面上添加一些标签来简化搜索。我找到了TTGTagCollectionView库。

当我使用TTGTagCollectionView时，搜索栏消失。我不明白为什么 enter image description here

这是我的配置代码

let collectionView = TTGTextTagCollectionView()

  override func viewDidLoad() {
    super.viewDidLoad()
    tagsConfig()
}
 
override func viewDidLayoutSubviews() {
     super.viewDidLayoutSubviews()
     collectionView.frame = CGRect(x: 0, y: (view.frame.height/6), width: view.frame.size.width, height: 100)
 }
 func tagsConfig(){
    collectionView.alignment = .center
    collectionView.delegate = self
    blackView.addSubview(collectionView)
    let tagConfig = TTGTextTagConfig()
    
    tagConfig.backgroundColor = #colorLiteral(red: 0.1333333333, green: 0.1333333333, blue: 0.1333333333, alpha: 1)
    tagConfig.textColor = .white
    tagConfig.borderColor = .white
    tagConfig.borderWidth = 1
    collectionView.backgroundColor = .white
    collectionView.addTags(["x","y","a","b","c","hi","you","test","hello","swift"], with: tagConfig)
    
    
}
