你们可以做以下工作,但首先确保你确定UIText。 代表你本人的外地代表

#define kOFFSET_FOR_KEYBOARD 350;

//method to move the view up/down whenever the keyboard is shown/dismissed

    CGRect rect = self.view.frame;
    if (movedUp)
    {
        // 1. move the view s origin up so that the text field that will be hidden come above the keyboard 
        // 2. increase the size of the view so that the area behind the keyboard is covered up.

        if (rect.origin.y == 0 ) {
            rect.origin.y -= kOFFSET_FOR_KEYBOARD;

您不应信任<代码>text FieldDidBeginEditing:,以调整关键板,因为即使用户正在使用物理键盘打打字,不会展示一个屏幕板。

Instead listen to the UIKeyboardWillShowNotification, that is only triggered when the keyboard will actually be displayed. You need to do a three step process:

1. Determine actual size of keyboard from the notifications userInfo dictionary. The size will differ from landscape/portrait, and different devices.
2. Update the contentInset using the determined size. You can do it animated, the notification will even tell you the duration for the keyboard animation.
3. Scroll the textfield into view, very easy to forget this!
