将根视图宽度设置为等于动态标签的宽度

Question

I'm using XIB to populate tableview of a chat app (messages). It contains a view and a label on it. The label's text continuously changes. How can I find the width of label and then set width of parent view equal to that?

I'm a newbie to swift. So, in this way, is it possible to set height also?

I have set the number of lines to '0' of the uilabel

Assuming that the "Message Text" label is the only subview within the parent view, you could set the parent view's height and width like so:

if let subview = view.subviews.first {
    // where `view` is your parent view and `subview` is your text label
    view.frame.size.width = subview.frame.width
    view.frame.size.height = subview.frame.height  
}
