大佬教程收集整理的这篇文章主要介绍了从 UIButton swift 呈现 UICollectionView，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
首先，我希望我不会违反任何规则或延长时间，但我真的被困住并花了一整天的时间，所以我很乐意获得帮助:)
好的，所以我有一个使用 Panmodel 3rd party 的弹出视图控制器，我在 UIbutton 自定义单元格中有一个 UItableVIEw，现在我想在用户按下按钮，现在我按照 Ray 教程（Link）了解如何制作自定义日历，但它仍然对我不起作用，出于某种原因，当我按下按钮时，它只显示清晰的视图 + 冻结我的屏幕：|，我将发布我的 tableVIEw 设置的代码 + UIbutton 的单元格，不打算发布日历的代码，因为它很长而且我不想发送垃圾邮件，如果需要我会发布:) 再次感谢您的帮助，真的花了一整天的时间，发现自己没有解决方案，所以这是我的代码：
代码：tableVIEwVC：
import UIKit import PanModal class FiltertableVIEwController: UItableVIEwController,PanModalPresentable { var panScrollable: UIScrollVIEw? { return tableVIEw } var albumsPickerIndexPath: IndexPath? // indexPath of the currently shown albums picker in tablevIEw. var datesCell = DatesCell() overrIDe func vIEwDIDLoad() { super.vIEwDIDLoad() setuptableVIEw() // registertableVIEwCells() } overrIDe func vIEwDIDLayoutSubvIEws() { super.vIEwDIDLayoutSubvIEws() // tableVIEw.frame = vIEw.bounds } overrIDe var preferredStatusbarStyle: UIStatusbarStyle { return .Lightcontent } // MARK: - VIEw Configurations func setuptableVIEw() { tableVIEw.leftAnchor.consTraint(equalTo: vIEw.leftAnchor,constant: 0).isActive = true tableVIEw.topAnchor.consTraint(equalTo: vIEw.topAnchor,constant: 0).isActive = true tableVIEw.rightAnchor.consTraint(equalTo: vIEw.rightAnchor,constant: 0).isActive = true tableVIEw.bottomAnchor.consTraint(equalTo: vIEw.bottomAnchor,constant: 0).isActive = true tableVIEw.separatorStyle = .singleline tableVIEw.isScrollEnabled = false tableVIEw.allowsSelection = true tableVIEw.rowHeight = UItableVIEw.automaticDimension tableVIEw.estimatedRowHeight = 600 tableVIEw.register(UItableVIEwCell.self,forCellReusEIDentifIEr: "cell") tableVIEw.BACkgroundcolor = #colorliteral(red: 1,green: 1,blue: 1,Alpha: 1) } func indexPathToInsertDatePicker(indexPath: IndexPath) -> IndexPath { if let albumsPickerIndexPath = albumsPickerIndexPath,albumsPickerIndexPath.row < indexPath.row { return indexPath } else { return IndexPath(row: indexPath.row + 1,section: indexPath.section) } } // MARK: - UItableVIEwDatasource overrIDe func tableVIEw(_ tableVIEw: UItableVIEw,numberOfRowsInSection section: int) -> Int { // if DatePicker is already present,we add one extra cell for that if albumsPickerIndexPath != nil { return 5 + 1 } else { return 5 } } overrIDe func tableVIEw(_ tableVIEw: UItableVIEw,cellForRowAt indexPath: IndexPath) -> UItableVIEwCell { switch indexPath.row { case 0: let byActivityCell = UINib(nibname: "byActivityCell",bundle: nil) self.tableVIEw.register(byActivityCell,forCellReusEIDentifIEr: "byActivityCell") let activityCell = tableVIEw.dequeueReusableCell(withIDentifIEr: "byActivityCell",for: indexPath) as! byActivityCell activityCell.SELEctionStyle = .none return activityCell case 1: let byTypeCell = UINib(nibname: "ByType",bundle: nil) self.tableVIEw.register(byTypeCell,forCellReusEIDentifIEr: "byTypeCell") let typeCell = tableVIEw.dequeueReusableCell(withIDentifIEr: "byTypeCell",for: indexPath) as!

发现问题，是自动布局的问题，我把自动布局改成这样：
override func viewDidLoad() { super.viewDidLoad() collectionView.BACkgroundColor = .yellow view.addSubview(dimmedBACkgroundView) view.addSubview(collectionView) var consTraints = [ dimmedBACkgroundView.leadingAnchor.consTraint(equalTo: view.leadingAnchor),dimmedBACkgroundView.TrailingAnchor.consTraint(equalTo: view.TrailingAnchor),dimmedBACkgroundView.topAnchor.consTraint(equalTo: view.topAnchor),dimmedBACkgroundView.bottomAnchor.consTraint(equalTo: view.bottomAnchor) ] consTraints.append(contentsOf: [ //1 collectionView.leadingAnchor.consTraint( equalTo: view.readableContentGuide.leadingAnchor),collectionView.TrailingAnchor.consTraint( equalTo: view.readableContentGuide.TrailingAnchor),//2 collectionView.centerYAnchor.consTraint( equalTo: view.centerYAnchor,constant: 10),//3 collectionView.heightAnchor.consTraint( equalTo: view.heightAnchor,multiplier: 0.5) ]) NSLayoutConsTraint.activate(consTraints) // NSLayoutConsTraint.activate([ // dimmedBACkgroundView.leadingAnchor.consTraint(equalTo: view.leadingAnchor),// dimmedBACkgroundView.TrailingAnchor.consTraint(equalTo: view.TrailingAnchor),// dimmedBACkgroundView.topAnchor.consTraint(equalTo: view.topAnchor),// dimmedBACkgroundView.bottomAnchor.consTraint(equalTo: view.bottomAnchor) // ]) }
