UITableViewCell 内的 UIScrollView 触摸检测 [英] UIScrollView inside UITableViewCell touch detect

问题描述

我有一个带有 8 个自定义单元格的 tableview.在第 8 个单元格中，我添加了一个启用分页的 scrollView，这样我就可以在没有非常高的单元格的情况下显示第 1 页和第 2 页(或第 3、4...10 页).

I have a tableview with 8 custom cells. in the 8th cell I added a scrollView with paging enabled so I can show page 1 and page 2 (or 3, 4... 10) without have a very high cell.

问题出在 scrollView 我不能使用 didSelectRowAtIndexPath 因为单元格在 scrollView 后面所以我试图检测 scrollView 点击(不是滑动).

The problem is with the scrollView I can't use didSelectRowAtIndexPath because the cell is behind the scrollView so I'm trying to detect scrollView tap (not swipe).

我玩过 touchesBegan 和 touchesEnded 但他们从来没有被调用过(我知道 touches 只适用于 UIView，但也许......)

I played with touchesBegan and touchesEnded but they are never called (I know touches work with UIView only, but maybe.....)

非常感谢任何帮助.

谢谢，最大

推荐答案

我找到了最简单的解决方案:

I found the simplest solution for my needs:

继承 UIScrollView touchesEnded 方法并发布通知.

subclass UIScrollView touchesEnded method and post a notification.

在 UITableview 中添加一个观察者在 viewdidAppear 中(在 viewdiddisappear 中移除它)来调用一个调用 tableview didSelectRowForIndexPath 的函数.

In the UITableview add an observer in viewdidAppear (remove it in viewdiddisappear) to call a function that call tableview didSelectRowForIndexPath.

类似的东西(快速版本)

Something like this (swift version)

// myScrollView.swift

import UIKit

class myScrollView: UIScrollView {
    override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
            NSNotificationCenter.defaultCenter().postNotificationName("selectTVRow", object: nil)
    }
}

在您的 tableView 中:

In your tableView:

// ItemsList.swift

    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
        NSNotificationCenter.defaultCenter().addObserver(self, selector: "selectFourthRow", name: "selectTVRow", object: nil)
    }

    override func viewDidDisappear(animated: Bool) {
        super.viewDidDisappear(animated)
        NSNotificationCenter.defaultCenter().removeObserver(self, name: "selectfourthrow", object: nil)
    }

    func selectFourthRow() {
        let rowToSelect:NSIndexPath = NSIndexPath(forRow: 4, inSection: 0);
        self.tableView(self.tableView, didSelectRowAtIndexPath: rowToSelect);
    }

    /*
    .... rest of your tableview Datasource and Delegate methods...
    numberOfSectionsInTableView, numberOfRowsInSection, cellForRowAtIndexPath
    */
