单击UIDatePicker后关闭键盘

Question

当用户点击UITextField然后点击直接开始与UIDatePicker控件交互时，我似乎无法解除键盘。

我正在使用以下功能来点按键盘：

// The following code will remove the keyboard when it is not editing...
var g = new UITapGestureRecognizer(() => View.EndEditing(true));
View.AddGestureRecognizer(g);

当用户点击UIDatePicker控件开始调整日期时，能否告诉我如何解除键盘？

Answer 1

您必须在ui元素上调用.ResignFirstResponder()。这应该会解雇键盘。

Answer 2

试试这段代码：

var tap = new UITapGestureRecognizer ();
tap.AddTarget (() => this.View.EndEditing (true));
this.View.AddGestureRecognizer (tap);
tap.CancelsTouchesInView = false;
