我有UIViewController
初始化UIView
。
此视图包含UITextField
或UIButton
等互动元素。
视图添加在方法底部的ViewDidLoad上,以确保当我看到它时,可以通过用户交互来访问。
但是当我显示视图时,无法在此视图上进行任何交互。
这是唯一可能的吗?我做错了吗?
The View
public class AddBusinessEventView : UIView
{
public UILabel LblTitle;
public UITextField TxtType;
public UIButton BtnClose;
public AddBusinessEventView(nfloat bw, nfloat bh)
{
//Bouton pour fermer le popup
BtnClose = new UIButton();
BtnClose.SetImage(UIImage.FromFile("Images/Boutons/lightbox_close.png"), UIControlState.Normal);
BtnClose.Frame = new CGRect(bw - 80, 30, BtnFermer.ImageView.Image.CGImage.Width * 0.5, BtnFermer.ImageView.Image.CGImage.Height * 0.5);
//Doit se trouver par dessus txtSite et ajouté après dans la vue pour se trouvé en premier plan
LblTitle = new UILabel();
LblTitle.Frame = new CGRect((bw - (lw + 200)) / 2, 100, lw + 200, 30);
LblTitle.Text = "Fill with your event elements";
LblTitle.Font = UIFont.FromName("GillSans-Bold", 22);
LblTitle.TextColor = UIColor.FromRGB(211, 3, 67);
LblTitle.TextAlignment = UITextAlignment.Center;
TxtType = new UITextField(new CGRect((bw - 750) / 2, 140, 350, 40));
TxtType.BackgroundColor = UIColor.White;
TxtType.TextAlignment = UITextAlignment.Center;
TxtType.BorderStyle = UITextBorderStyle.RoundedRect;
TxtType.AutocorrectionType = UITextAutocorrectionType.No;
TxtType.AutocapitalizationType = UITextAutocapitalizationType.AllCharacters;
TxtType.Placeholder = "Type";
AddSubviews(BtnClose, LblTitle, TxtType);
}
}
UIViewController
partial class EvenementViewController : EnhancedUIViewController
{
AddBusinessEventView AddBusinessEventView;
public EvenementViewController(IntPtr handle) : base(handle) { }
public EvenementViewController() : base() { }
public override void ViewDidAppear(bool animated)
{
base.ViewDidAppear(animated);
if (myEvent == null)
{
ShowAddBusinessEventView();
}
}
public override void ViewDidLoad()
{
base.ViewDidLoad();
nfloat bw = View.Bounds.Width;
nfloat bh = View.Bounds.Height;
//Another Elements are adding to view here
//...
AddBusinessEventView = new AddBusinessEventView(bw, bh);
AddBusinessEventView.Hidden = true;
//Much more View.Add with all elements here
//...
View.Add(AddBusinessEventView);
AddBusinessEventView.BtnType.TouchUpInside += BtnClose_TouchUpInside;
}
#region BusinessEventAdd
void ShowAddBusinessEventView()
{
UIView.Animate(duration: 1,
delay: 0,
options: UIViewAnimationOptions.CurveEaseInOut,
animation: () =>
{
AddBusinessEventView.Alpha = 1.0f;
},
completion: () =>
{
AddBusinessEventView.Hidden = false;
AddBusinessEventListener();
}

}
void HideAddBusinessEventView()
{
UIView.Animate(duration: 1,
delay: 0,
options: UIViewAnimationOptions.CurveEaseInOut,
animation: () =>
{
AddBusinessEventView.Alpha = 0.0f;
},
completion: () =>
{
AddBusinessEventView.Hidden = true;
RemoveBusinessEventListener();
}
);
}
void BtnClose_TouchUpInside(object sender, EventArgs e)
{
System.Diagnostics.Debug.Print("Touching myself");
}

请将EnhancedViewController称为标准的UIViewController,我正在添加一些增强功能,以向用户显示来自Overlay的消息。
正如我所说,我们不能与TxtType或BtnClose互动。
编辑:
不确定它是否可以提供帮助;但是当View
添加到View
上的主UIViewController
时,它会很好地显示,但所有用户互动都是此View
下元素的捕获
即:AddBusinessEventView
充当弹出窗口,所以它覆盖了所有其他元素,当我按下一个元素时,如果在此View
之前添加的另一个元素在其中,则它是这个元素而不是抓住触摸事件的AddBusinessEventView
元素。
如上所述,主要目的是在不同文件上剪切View元素,以提高此应用程序的可读性和可维护性。enter code here

没有理由你不能这样做。 您可以像
那样构建代码然后在任何Controller中使用View1和View2。
我尝试了你的代码,我正确地弹出了所有东西。 正如您所说,如果视图显示在屏幕上,但是来自下方的另一个视图中的元素与用户交互,则您可以尝试将视图置于最前面。
试试这个
View.BringSubviewToFront(AddBusinessEventView);
在ViewDidLoad函数的末尾。
