我有 UITableView。在 UITableViewCell 中,我放置了 UICollectionView。当前所有行单独滚动。我需要的是当用户以水平方式(从左到右或从右到左)滚动任何行时,所有行必须以相同的模式滚动。

我点击了下面的链接但是没有成功

Scroll Multiple UICollectionView with one collectionview IOS

Manually scrolling two UICollectionViews showing the same content

请看我的代码

View Controller

import UIKit

class ViewController: UIViewController, UITableViewDataSource {

var categories = ["Header 1", "Header 2", "Header 3", "Header 4", "Header 5", "Header 6", "Header 7", "Header 8"]

@IBOutlet var myTableView: UITableView!

override func viewDidLoad() {
super.viewDidLoad()

myTableView.dataSource = self
}

override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}

func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return categories[section]
}

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return categories.count
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("cell") as? CategoryRow
if cell == nil {
cell = CategoryRow(style:UITableViewCellStyle.Subtitle, reuseIdentifier:"cell")
}
else {
}
cell!.tag = indexPath.section
cell?.collection.reloadData()
return cell!
}
}

MyCollectionViewCell

import UIKit

class MyCollectionViewCell: UICollectionViewCell {

@IBOutlet var title: UILabel!
@IBOutlet var data: UILabel!
}

类别行

import UIKit

Synchronized horizontal scrolling of collection views in tableview rows

提前致谢

最佳答案

假设您有 2 个 Collection View 。你可以做的是这样的事情。

// say cv0 and cv1 are outlets to two table views

func scrollViewDidScroll(scrollView: UIScrollView) {
if scrollView == self.cv0 {
self.cv1.contentOffset = self.cv0.contentOffset
}
else {
if scrollView == self.tv1 {
self.cv0.contentOffset = self.cv1.contentOffset
}
}
}

如果你想要更多的 Collection View ,你可以写一个通用的方法来处理它。您可以将 scrollView 传递给此方法,并相应地设置堆栈 contentOffSet 中的所有其他 ScrollView 。
