我有一个奇怪的事情。在模拟器iOS 10.3上。以下代码工作正常。
set.Bind(Circle1).For("Selected").To(vm => vm.PincodeCircles[0].Activated);
在我的iPad Pro 12.9上,出现以下错误:
[0:] MvxBind:警告:2.68无法为PincodeCircles [0]选择的绑定创建目标绑定。激活
我已经尝试了以下内容:
set.Bind(Circle1).For(button => button.Selected).To(vm => vm.PincodeCircles[0].Activated);
并给出了同样的错误:
[0:] MvxBind:警告:4.27无法为PincodeCircles [0]选择的绑定创建目标绑定.Activated
在viewmodel上激活的定义如下:
public bool Activated
{
get { return this._activated; }
set { this.SetProperty(ref this._activated, value); }
}
Cirle1按钮的类型为UICircleButton。这是班级:
using CoreGraphics;
using Foundation;
using System;
using UIKit;
namespace NN.Plugin.Utils.iOS
{
public partial class UICircleButton : UIButton
{
public UICircleButton(IntPtr handle) : base(handle)
{
Layer.BorderColor = UIColor.Black.CGColor;
Layer.BorderWidth = 2;
}
public nfloat BorderWidth
{ get
{
return Layer.BorderWidth;
}
set
{
Layer.BorderWidth = value;
}
}
public CGColor BorderColor
{
get
{
return Layer.BorderColor;
}
set
{
Layer.BorderColor = value;
}
}
public nfloat PointSize
{
get => Font.PointSize;
set => Font = Font.WithSize(value);
}
public override CGRect ContentRectForBounds(CGRect rect)
{
var newRect = base.ContentRectForBounds(rect);
Layer.CornerRadius = newRect.Width / 2;
return newRect;
}
}
}
