我想在iOS搜索栏中隐藏“取消”按钮。我已经实现了以下自定义渲染器代码，但似乎无法正常工作。如果有人知道解决方案，请分享。

public class iOSSearchBar : SearchBarRenderer 
    {
        protected override void OnElementChanged(ElementChangedEventArgs<SearchBar> args)
        {
            base.OnElementChanged(args);

        UISearchBar bar = (UISearchBar)this.Control;

        bar.AutocapitalizationType = UITextAutocapitalizationType.None;
        bar.AutocorrectionType = UITextAutocorrectionType.No;
        //bar.BarStyle = UIBarStyle.Default;
        //bar.BarTintColor = UIColor.LightGray;
        //bar.KeyboardType = UIKeyboardType.ASCIICapable;
        bar.SearchBarStyle = UISearchBarStyle.Minimal;
        bar.SetShowsCancelButton(false, false);
        bar.ShowsCancelButton = false;
}
}
