【问题描述】:
我想创建一个与表格视图单元格高度动态相关的页脚。
我最初的情况是这样的:
如果我点击一行,它会将此单元格的高度更改为 194(之前为 44)
它不显示所有行。
如果我得到页脚 -150,它看起来像:
如果我关闭所有单元格,它看起来像这样,我用 -150 到达页脚的 150 在这里是白色的:
我的代码:
var selectedCellIndexPath: Int?
let selectedCellHeight: CGFloat = 194.0
let unselectedCellHeight: CGFloat = 44.0
var cellsHeight = [44, 44, 44]
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.beginUpdates()
if selectedCellIndexPath != nil && selectedCellIndexPath == indexPath.row {
selectedCellIndexPath = nil
}
else {
selectedCellIndexPath = indexPath.row
}
if selectedCellIndexPath != nil {
tableView.scrollToRow(at: indexPath, at: .none, animated: true)
}
tableView.endUpdates()
}
func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
let rowHeight:CGFloat = 44
var rowsHeight:CGFloat = 3 * rowHeight
/*for i in 0..<cellsHeight.count {
rowsHeight += CGFloat(cellsHeight[i])
}*/
let topHeight = UIApplication.shared.statusBarFrame.height + self.navigationController!.navigationBar.frame.height
let viewHeight = self.view.frame.height
let headerHeight:CGFloat = 30
let height = viewHeight - topHeight - rowsHeight - headerHeight //- 150
return CGFloat(height)
}
只有一排的高度为 194,另一排为 44。任何想法如何解决这个问题? 谢谢
编辑:
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}

let cell = tableView.dequeueReusableCell(withIdentifier: "workoutDateCell", for: indexPath) as! WorkoutDateTableViewCell
cell.typeLabel.text = "Beginn"
cell.dateDatepicker.date = Date()
