Add two observers
添加两个观察者
NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardVisible:", name: UIKeyboardDidShowNotification, object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardHidden:", name: UIKeyboardDidHideNotification, object: nil)
func keyboardVisible(notif: NSNotification) {
print("keyboardVisible")
}
func keyboardHidden(notif: NSNotification) {
print("keyboardHidden")
}
Whenever the keyboard is visible keyboardVisiblewill be called and whenever the keyboard is hidden keyboardHiddenwill be called.
每当键盘可见时keyboardVisible将被调用，每当键盘隐藏时keyboardHidden将被调用。

Try this check:
试试这个检查：
let app = XCUIApplication()
XCTAssert(app.keyboards.count > 0, "The keyboard is not shown")
Or check for specific keyboard keys like:
或检查特定的键盘键，如：
let app = XCUIApplication()
XCTAssert(app.keyboards.buttons["Next:"].exists, "The keyboard has no Next button")
You can also control interactions on the keyboard:
您还可以控制键盘上的交互：
let app = XCUIApplication()
app.keyboards.buttons["Next:"].tap()

I found the keyboard count check didnt work on one of my apps (it returned a count of 1 even when the keyboard was hidden), so amended it slightly:
我发现键盘计数检查在我的一个应用程序上不起作用（即使键盘隐藏，它返回的计数也是 1），所以稍微修改了一下：
private fund isKeyboardShown() -> Bool {
return XCUIApplication().keyboards.keys.count > 0
}
