自定义UITableViewCell，向其中添加button，button的点击事件无法响应

stackoverflow

I faced a similar issue. I was programmatically adding an UIButton to the UITableViewCell via addSubview. The button would not respond to touch events. Using Debug View Hierarchy, I finally discovered that any subviews added to the UITableViewCell was behind contentView, which was blocking user input from reaching the UIButton. The issue was resolved by adding the UIButton to contentView instead of the UITableViewCell.

这是因为向cell addSubview:button button会被cell自带的contentView挡住，应该向cententView添加subview
