I have a custom tableviewcell with the standard disclosure indicator positioned in the centre vertically by default. How can I move this standard disclosure indicator vertically like in the iOS mail app?

推荐答案

你可以调整默认附件的位置.然后，您可以简单地在 layoutSubviews 或您选择的任何位置更新附件按钮的框架:

You can adjust the position of the default accessory by subclassing your cell and finding the UIButton in the cell's subviews (which represents the indicator) and holding a reference to it. You can then simply update the frame of the accessoryButton in layoutSubviews or wherever you choose like so:

class CellSubclass: UITableViewCell {

    var accessoryButton: UIButton?

    override func awakeFromNib() {
        super.awakeFromNib()
        accessoryType = .DisclosureIndicator
        accessoryButton = subviews.flatMap { $0 as? UIButton }.first
    }

    override func layoutSubviews() {
        super.layoutSubviews()
        accessoryButton?.frame.origin.y = 8
    }
}
