是否可以将UIViewController的Title绑定到ViewModel字符串属性？它似乎永远不会更新.作为一个副作用,如果你没有在绑定之前将标题设置为某些东西,那么当set.Apply()被调用时,Mvvmcross代码中会出现崩溃.
UIViewController没有.xib,我不确定这是否是问题的一部分.
public override void ViewDidLoad()
{
base.ViewDidLoad();
var set = this.CreateBindingSet<HomeView, HomeViewModel>();
set.Bind(Title).To(vm => vm.ProjectName);
set.Apply();
}
这是堆栈跟踪
