ios – 如何截断UITableView Cell TextLabel中的文本,以便它不会隐藏DetailTextLabel？

在布局具有UITableViewCellStyle.Value1样式的单元格时,标题标签似乎优先,并将详细标签推出视图.解决方案可能是继承UITableViewCell并覆盖其layoutSubviews()：

override func layoutSubviews() {
        super.layoutSubviews()

        if let detail = self.detailTextLabel {
            // this will do the actual layout of the detail 
            // label's text,so you can get its width
            detail.sizeToFit() 

            // you might want to find a cLever way to calculate this
            // instead of assigning a literal
            let rightMargin: CGFloat = 16

            // adjust the detail's frame
            let detailWidth = rightMargin + detail.frame.size.width
            detail.frame.origin.x = self.frame.size.width - detailWidth
            detail.frame.size.width = detailWidth
            detail.textAlignment = .Left

            // Now truncate the title label        
            if let text = self.textLabel {
                if text.frame.origin.x + text.frame.size.width > self.frame.width - detailWidth {
                    text.frame.size.width = self.frame.width - detailWidth - text.frame.origin.x
                }
            }
        }
    }

请注意,尽管detail.textAlignment = .Left我们考虑了细节的宽度,实际文本最终与右侧对齐.
