我有一个非常简单的问题——太简单了,我觉得有点尴尬。当我无法从 appdelegate 类访问窗口时,如何向视图添加控件。这是我从中遍历的屏幕。(这只是 viewdidload 方法)
我以为 window.AddSubview(btnSubmit); 会起作用,但在 appdelegate 类之外无法识别窗口。
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
var btnSubmit = UIButton.FromType (UIButtonType.RoundedRect);
var frame = new System.Drawing.RectangleF (35f, 30f, 250f, 40f);
btnSubmit.Frame = frame;
btnSubmit.SetTitle ("Return Home", UIControlState.Highlighted);
btnSubmit.TouchUpInside += (sender, e) =>
{
btnSubmit.SetTitle("Clicked", UIControlState.Normal);
};
// Perform any additional setup after loading the view, typically from a nib.
}
