在以下方法或属性之间的调用是不明确的：'​​MvvmCross.Binding.BindingContext.MvxBindingContextOwnerExtensions

Question

我正在用MvvmCross编写一个简单的Xamarin应用程序。我只是想做一些绑定，但是编译器给了我这个错误

  

以下方法或属性之间的调用不明确：“ MvvmCross.Binding.BindingContext.MvxBindingContextOwnerExtensions.CreateBindingSet（TTarget）”和   'MvvmCross.Binding.BindingContext.MvxBindingContextOwnerExtensions.CreateBindingSet（TTarget）**。在var set = this.CreateBindingSet<LoginViewController, LoginViewModel>();

处引发此错误

我在Xamarin.iOS项目中添加了MvvmCross，MvvmCross.Binding，MvvmCross.Platform和MvvmCross.Core。

请帮助摆脱该错误。下面是我的ViewController的代码：

using Kinettix.Core.ViewModels;
using MvvmCross.Binding.BindingContext;
using MvvmCross.Platforms.Ios.Views;
using UIKit;

namespace Kinettix.iOS.Views
{
    public partial class LoginViewController : MvxViewController<LoginViewModel>
    {
        public LoginViewController() : base("LoginViewController", null)
        {
        }

        public override void ViewDidLoad()
        {
            base.ViewDidLoad();
            this.NavigationController.NavigationBarHidden = true;


            var set = this.CreateBindingSet<LoginViewController, LoginViewModel>();
            set.Apply();

            tfUsername.ShouldReturn+= (sender) =>
            {
                sender.ResignFirstResponder();
                return false;
            };

            tfPassword.ShouldReturn += (sender) =>
            {
                sender.ResignFirstResponder();
                return false;
            };


        }



        public override void DidReceiveMemoryWarning()
        {
            base.DidReceiveMemoryWarning();
            // Release any cached data, images, etc that aren't in use.
        }
    }
}

好的。我找到了我问题的答案。我的iOS项目中有MvvmCross.Core，MvvmCross.Platform，MvvmCross.binding和MvvmCross。它抱怨在MvvmCross和MvvmCross.Binding之间对CreateBindingSet的模棱两可的调用。我删除了所有软件包，仅安装了MvvmCross。这样，它使用MvvmCross调用了CreateBindingSet并成功运行。 ：）
