uiswitch

问题 In Xamarin Forms, I created a custom renderer for Switch . On iOS, I updated the scale transform to make it smaller than its default size: Control.Transform = CGAffineTransform.MakeScale((float)0.75, (float)0.75); While this successfully resizes the Switch , it doesn't resize its bounding box. How can I resize it as well? Here the background color of the Switch is set to red in XAML. It looks like the original bounds are still being maintained even though the thumb is smaller. 回答1: You can

问题 I am working on a iOS app that has two ViewControllers . The first is a TableView which creates a row for each index in a array. Each cell of this TableView shows the content in the array corresponding to the index and has a switch. The second ViewController has an image and a label and they are supposed to change depending the switch state. So, how can I get the switch state from a specific cell? import UIKit class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate

Also, it's not possible to tap on just the toggle switch itself - you have to interact with the cell itself to toggle the switch, the switch itself is not an accessible element. In my app I have the exact same setup with a label and a switch. But when I tap the cell with
