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

问题描述

我有一个包含8个自定义单元格的表格视图.在第8个单元格中，我添加了启用分页功能的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3、4 ... 10).

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.

scrollView的问题是我不能使用didSelectRowAtIndexPath，因为单元格在scrollView的后面，所以我试图检测scrollView的轻击(不滑动).

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，但它们从未被使用(我知道touches仅适用于UIView，但也许.....)

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

非常感谢您的帮助.

谢谢， 最高

推荐答案

我找到了最简单的解决方案:

I found the simplest solution for my needs:

子类UIScrollView touchesEnded方法并发布通知.

subclass UIScrollView touchesEnded method and post a notification.

在UITableview中，在viewdidAppear中添加一个观察者(在viewdiddisappear中将其删除)，以调用调用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
    */
