Question

我们的申请中遇到了一个令人讨厌的问题。我们使用UIWebView作为某些卡支付资料（3Dsecure）并遇到了UIKeyboard的问题。点击网页的输入字段时，它会获得焦点，您可以看到光标，但键盘不会出现：

Input field has cursor, but no keyboard on the screen

但实际上你可以按下按钮并输入作品：

另一个奇怪的行为是关于通知。如果我将观察者添加到UIKeyboardWillShowNotification，UIKeyboardDidChangeFrameNotification和UIKeyboardDidShowNotification，则只会调用willShow方法。通知数据也与UITextField的键盘通知不同。

的UITextField ：

{name = UIKeyboardWillShowNotification; userInfo = {
UIKeyboardAnimationCurveUserInfoKey = 7;
UIKeyboardAnimationDurationUserInfoKey = "0.35";
UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 216}}";
UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 460}";
UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 460}";
UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 352}, {320, 216}}";
UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 352}, {320, 216}}";}}

网页输入字段

{name = UIKeyboardWillShowNotification; userInfo = {
UIKeyboardAnimationCurveUserInfoKey = 7;
UIKeyboardAnimationDurationUserInfoKey = "0.25";
UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 260}}";
UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 698}";
UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 438}";
UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 568}, {320, 260}}";
UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 308}, {320, 260}}";}}

已经尝试过任何与半身相关的UIWebView-keyboard修正案，例如[window makeKeyAndVisible]。没运气。经常在模拟器和设备上重现（iPhone5 iOS8.4，模拟器iPhone5 iOS8.3）。

还有一件事：离开此屏幕后，调用原生UITextField的键盘也会被破坏 - 它们出现（没有动画），您可以输入一些字母。但是当你完成键盘停留在屏幕上并将触摸传递到视图时。

有什么想法吗？真的很感激对此的一些想法！提前谢谢！

UIWebView键盘是透明的
