Question

当我的UITableViewCell行显示出来时，它们的高度为44，绝对不应该这样做。我已经限制了整个路径的顶部到底部，正如您在下面的警告中看到的关于不良约束。

忽略它不喜欢我的$ ballIsSquare $高度/宽度约束的事实，我仍然应该有一个高度超过44的单元格。它显示几乎圆形的球，意味着高度几乎是55高（因为它显示$ ballWidth $为55.但是，它根本没有显示日期标签，这被限制在球的上方。任何想法细胞是什么被迫如此小？

视图控制器为此指定估计行高100，并且rowHeight设置为UITableViewAutomaticDimension。

我认为“UISV-alignment”和UISV-canvas-connection是来自正在使用的UIStackView的约束（例如$ ballsBottom $指的是球UIStackView）

UIView-Encapsulated-Layout-Height在我看来是真正的问题。

Will attempt to recover by breaking constraint

Answer 1

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
{
    if(indexPath.section == 0){
        return 50
    }else{
        return 120
    }
}

在视图控制器中添加此委托方法

或者您可以使用

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat { 
       return UITableViewAutomaticDimension
}

用于自动尺寸

为什么我的UITableViewCell行被强制为44？
