[已解决]Swift中的UITableView中自定义UITableViewCellAccessoryType

Swift crifan 5212浏览 0评论

[记录]用swift实现TableView中添加用户头像和右边显示时间

期间,需要去显示自定义的

 

然后要去确保右边显示

上边显示日期或对应文字:昨天

下边显示图片:开启免打扰模式

 

然后试了试:

enum UITableViewCellAccessoryType : Int {
    case None
    case DisclosureIndicator
    case DetailDisclosureButton
    case Checkmark
    case DetailButton
}

都没有符合要求的。

 

所以要去解决。

 

搜:

swift custom UITableViewCellAccessoryType

swift custom UITableViewCell AccessoryType

参考:

Swift tableView cell set accessory type – Stack Overflow

感觉是:

可以设置accessoryType为None,然后自定义accessoryView

去试试

 

然后是可以工作的:

        cell.accessoryType = UITableViewCellAccessoryType.None
        cell.accessoryView = UIView(frame: CGRectMake(0, 0, 48, 48))
        cell.accessoryView?.backgroundColor = UIColor.greenColor()

效果:

can show right accessory of table view cell

 

然后再去想办法:

自定义内部的view,

上面加个文字:显示时间

下面显示图片:显示防打扰

 

然后用代码:

       cell.accessoryType = UITableViewCellAccessoryType.None
        cell.accessoryView = UIView(frame: CGRectMake(0, 0, 48, 48))
        //cell.accessoryView?.backgroundColor = UIColor.yellowColor()
       
        let lastPublishTimeText = UILabel(frame: CGRectMake(0, 0, (cell.accessoryView?.bounds.size.width)!, 12))
        lastPublishTimeText.text = "昨天"
        lastPublishTimeText.textColor = UIColor.grayColor()
        lastPublishTimeText.font = UIFont.boldSystemFontOfSize(10)
        lastPublishTimeText.textAlignment = NSTextAlignment.Center
       
        let preventDisturbIconView = UIImageView(image:UIImage(named:"prevent_disturb.png"))
        preventDisturbIconView.frame = CGRectMake(
            12,
            12,
            preventDisturbIconView.bounds.size.width,
            preventDisturbIconView.bounds.size.height)
       
        cell.accessoryView?.addSubview(lastPublishTimeText)
        cell.accessoryView?.addSubview(preventDisturbIconView)

效果是:

table view cell right show clock

 

暂时凑合着可以显示了。

但是很明显:

accessory,离右边还是有点距离的-》所以要去搞懂,accessory如何靠最右对齐:

[无需解决]Swift中UITableView中让Cell的Accessory靠右对齐

 

以及:

对于前面加的cell.accessoryView的UIView内部,如何让一个label和一个Image的view,内部如何对齐父级的View,即cell.accessoryView:

[已解决]Swift中子View如何设置在父级View的对齐方式

[已解决]Swift中的UITableView中自定义UITableViewCellAccessoryType

期间,需要去:

对于cell的accessory的view中的:

上面的label

下面的image

两个view,设置子view在父view(accessory)中的对齐方式:

比如靠左或靠右对齐。

 

最后用代码:

        cell.accessoryType = UITableViewCellAccessoryType.None
        cell.accessoryView = UIView(frame: CGRectMake(0, 0, CGFloat(rowHeight), CGFloat(rowHeight)))
        //cell.accessoryView?.backgroundColor = UIColor.yellowColor()
       
        //let lastPublishTimeText = UILabel(frame: CGRectMake(0, 0, (cell.accessoryView?.bounds.size.width)!, 24))
        let lastPublishTimeText = UILabel(frame: CGRectMake(0, 0, (cell.accessoryView?.bounds.size.width)!, CGFloat(rowHeight)/2))
       
        lastPublishTimeText.text = "昨天"
        lastPublishTimeText.textColor = UIColor.grayColor()
        lastPublishTimeText.font = UIFont.boldSystemFontOfSize(10)
       
        let preventDisturbIconView = UIImageView(image:UIImage(named:"prevent_disturb_16x24.png"))
        preventDisturbIconView.frame = CGRectMake(
            0, //32,
            CGFloat(rowHeight)/2, //24,
            //preventDisturbIconView.frame.size.width,
            //preventDisturbIconView.bounds.size.width,
            preventDisturbIconView.bounds.size.width,
            //(cell.accessoryView?.bounds.size.width)!,
            //preventDisturbIconView.bounds.size.height)
            CGFloat(rowHeight)/2)

        cell.accessoryView?.addSubview(lastPublishTimeText)
        cell.accessoryView?.addSubview(preventDisturbIconView)
       
        //both align center of accessory
        lastPublishTimeText.textAlignment = NSTextAlignment.Center
        preventDisturbIconView.center = CGPointMake(
            (cell.accessoryView?.bounds.size.width)!/2,
            preventDisturbIconView.bounds.size.height/2 + lastPublishTimeText.frame.size.height)
       
        //both align right of accessory
        lastPublishTimeText.textAlignment = NSTextAlignment.Right
        preventDisturbIconView.frame.origin.x = (cell.accessoryView?.bounds.size.width)! - preventDisturbIconView.bounds.size.width

效果如下:

finally right show customized accessory

 

[总结]

此处,想要自定义UITableView中的UITableViewCellAccessoryType,主要思路是:

设置为accessoryType为UITableViewCellAccessoryType.None

然后再去新建一个UIView给accessoryView

然后再去把其他自定义的子view加入到这个accessoryView中即可

示例代码:

cell.accessoryType = UITableViewCellAccessoryType.None
cell.accessoryView = UIView(frame: CGRectMake(0, 0,80,55))

let lastPublishTimeText = UILabel(frame: CGRectMake(0, 0, (cell.accessoryView?.bounds.size.width)!, CGFloat(rowHeight)/2))
lastPublishTimeText.textColor = UIColor.grayColor()
lastPublishTimeText.font = UIFont.boldSystemFontOfSize(10)

let preventDisturbIconView = UIImageView(image:UIImage(named:"prevent_disturb_16x24.png"))
preventDisturbIconView.frame = CGRectMake(0,27,80,27)

//both align right of accessory
lastPublishTimeText.textAlignment = NSTextAlignment.Right
preventDisturbIconView.frame.origin.x = (cell.accessoryView?.bounds.size.width)! - preventDisturbIconView.bounds.size.width

cell.accessoryView?.addSubview(lastPublishTimeText)
cell.accessoryView?.addSubview(preventDisturbIconView)
