Question

我使用ExpandableView创建了一个菜单我有这个github存储库：

https://github.com/SubhiH/ExpandableTableView

实施后我需要知道如何知道单击单元格标签的时间，因为我需要在单击此标签时进行制作，然后将其重定向到另一个视图。每个标签都会重定向到不同的视图，以便了解何时单击它们。重定向我已经知道该怎么做但我试图检查标签何时被选中而不能。

有谁知道如何调整代码才能做到这一点？

下面是菜单图片和代码示例：

当我点击col3_row1等中的示例时，看到我想知道的图像，而不是在主单元格中。

Answer 1

如果你搜索这样的解决方案：

let label = tableView.cellForRowAtIndexPath(indexPath)?.viewWithTag(3)!
if (CGRectContainsPoint(label.frame, pointInCell)) {
    // user tapped image
} else {
    // user tapped cell
}

然后这个解决方案可以完美地为您量身定做：

Distinguish which part of UITableViewCell has been clicked

Answer 2

使用标签的手势属性并在其中指定点击手势，您可以通过该手势触发标签触摸上的方法。这是代码：

//Creating Label
actionlabel = UILabel()

//Setting Frame
actionlabel.frame = CGRectMake(...) // Provide label frame accordingly

//Adding TapGesture to make UILabel touchable
let tapGesture = UITapGestureRecognizer(target: self, action: "fireActionMethod:")

谢谢。
