多重选择在IOS中无法正常工作 [英] Multi select is not working properly in IOS

问题描述

我在iOS表格视图中为行设置复选标记时遇到问题 如果我在上方选择了一个元素，那么下一个第13个元素也会被选中，我不确定为什么吗?

I have a problem with setting the checkmark for a row in iOS table view If I select one element above, the next 13th element is also getting selected, I not sure why?

在设置复选标记之前，我必须对表做些什么，因为我只是在检查一个条件，如果该条件为真，则将附件类型设置为复选标记，下面是代码.

Should I have to do something with the table before setting the checkmark, cause I am just checking one condition and if that condition is true I am setting the accessoryType as checkmark, below is the code.

注意:-发生这种情况时，第13行将不会被选中，它只会更改该行的附件类型.

Note:- When this happen the 13th row will not get selected, it just changes the accessory type of that row.

if let cell = tableView.cellForRowAtIndexPath(indexPath) {
                if cell.selected {
                    if(self.sections[indexPath.section].files[indexPath.row].type != "cloud"){
                        print(self.sections[indexPath.section].files[indexPath.row])
                        cell.accessoryType = .Checkmark
                        NSNotificationCenter.defaultCenter().postNotificationName("enableOptions", object: nil)
                    }
                }
            }

CellForIndexPath代码:

CellForIndexPath Code:

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! MyFilesTableViewCell

        let fileSection = sections[indexPath.section]
        let file = fileSection.files[indexPath.row]

        cell.title.text = file.name
        if file.timeStamp.isEmpty{
            cell.timeStamp.hidden = true
        }else{
            cell.timeStamp.hidden = false
            cell.timeStamp.text = file.timeStamp
        }
        cell.icon.image = file.icon
        cell.actionsBtn.row = indexPath.row
        cell.actionsBtn.section = indexPath.section
        cell.actionsBtn.setTitle("\u{f142}", forState: .Normal)
        cell.actionsBtn.addTarget(self, action: #selector(MyFilesTableViewController.buttonClicked(_:)), forControlEvents: UIControlEvents.TouchUpInside)
        if(editingTable){
            cell.actionsBtn.hidden = true
        }else{
            cell.actionsBtn.hidden = false
        }
        if(file.type == "cloud"){
            cell.actionsBtn.hidden = true
        }
        cell.progressBar.progress = 0.0
        cell.progressBar.hidden = true
        return cell
    }

推荐答案

您的单元格在cellForRowAtIndexPath中可重用的问题.请使用下面的代码.

Its problem with your cell reusable in cellForRowAtIndexPath. Kindly use the below code.

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! MyFilesTableViewCell

cell.accessoryType = .None

if cell.selected {
                if(self.sections[indexPath.section].files[indexPath.row].type != "cloud"){
                    print(self.sections[indexPath.section].files[indexPath.row])
                    cell.accessoryType = .Checkmark
                }
            }

let fileSection = sections[indexPath.section]
let file = fileSection.files[indexPath.row]

cell.title.text = file.name
if file.timeStamp.isEmpty{
    cell.timeStamp.hidden = true
}else{
    cell.timeStamp.hidden = false
    cell.timeStamp.text = file.timeStamp
}
cell.icon.image = file.icon
cell.actionsBtn.row = indexPath.row
cell.actionsBtn.section = indexPath.section
cell.actionsBtn.setTitle("\u{f142}", forState: .Normal)
cell.actionsBtn.addTarget(self, action: #selector(MyFilesTableViewController.buttonClicked(_:)), forControlEvents: UIControlEvents.TouchUpInside)
if(editingTable){
    cell.actionsBtn.hidden = true
}else{
    cell.actionsBtn.hidden = false
}
if(file.type == "cloud"){
    cell.actionsBtn.hidden = true
}
cell.progressBar.progress = 0.0
cell.progressBar.hidden = true
return cell
}
