如何 set/change UIBarButtonItem 的标题字体大小

Question

这是我做的例子

self.NavigationItem.SetRightBarButtonItem(new UIBarButtonItem(Title:"want to let this text be smaller", UIBarButtonItemStyle.Plain, (object sender, EventArgs e) => webView.EvaluateJavascript ("window.location.href=")), true);

试了很多方法都没有解决这个问题

试试这个：

var button = new UIBarButtonItem("want to let this text be smaller", UIBarButtonItemStyle.Plain, (object sender, EventArgs e) => webView.EvaluateJavascript ("window.location.href="));

var fontAttribute = new UITextAttributes();
fontAttribute.Font = UIFont.SystemFontOfSize(8);

button.SetTitleTextAttributes(fontAttribute, UIControlState.Normal);

NavigationItem.SetRightBarButtonItem(button, true);
