Calculate the contentsize of scrollview

Question

I\'m having a scrollview as the detailedview of tableview cell. There are multiple views on the detailedview like labels, buttons etc. which I\'m creating through interface

Answer 1

I had the same situation, but then I wrote a new version in Swift 4 mirroring the better answer in Objective-C by Hannes Larsson:

import UIKit

extension UIScrollView {
    func fitSizeOfContent() {
        let sumHeight = self.subviews.map({$0.frame.size.height}).reduce(0, {x, y in x + y})
        self.contentSize = CGSize(width: self.frame.width, height: sumHeight)
    }
}
