当我在 iOS 13 模拟器上部署时，class Program
{
static void Main(string[] args)
{
var p = new Person
{
Professions = new List<Profession>
{
new Profession("Joker"),
new Profession("Smoker"),
new Profession("Midnight toker")
}
};
var accessor = ObjectAccessor.Create(p);
var professions = accessor[nameof(Person.Professions)];
if (professions is IEnumerable)
{
foreach (var profession in (IEnumerable)professions)
{
Console.WriteLine(profession);
}
}
}
}
class Person
{
public List<Profession> Professions { get; set; }
}
class Profession
{
public string Name { get; set; }
public Profession( string name)
{
Name = name;
}
public override string ToString()
{
return Name;
}
}
不会调用其操作选择器。相同的代码适用于 iOS 12 模拟器设备和真实的iOS 13硬件。
UIScreenEdgePanGestureRecognizer我已经创建了small sample project。在iOS 12模拟器中滑动即可。在iOS 13模拟器中，不会调用选择器方法override func viewDidLoad() {
super.viewDidLoad()
let edgePan = UIScreenEdgePanGestureRecognizer(target: self, action: #selector(screenEdgeSwiped))
edgePan.edges = .left
view.addGestureRecognizer(edgePan)
}
@objc func screenEdgeSwiped(_ recognizer: UIScreenEdgePanGestureRecognizer) {
if recognizer.state == .recognized {
print("swipe gesture recognized ✔︎")
}
}
。

尝试为iOS模拟器启用Window > Show Device Bezels。我向Apple提交了一个有关此功能不能像以前那样起作用的错误（FB7253111），但他们说这是有意更改。
