Question

我遇到了问题，当设备方向是FaceUp时，来自UIKeyboardWillShowNotification观察者的userInfo没有给我很好的价值......

//WHEN FACEUP -> Wrong Values
Keyboard will show: {
    UIKeyboardAnimationCurveUserInfoKey = 7;
    UIKeyboardAnimationDurationUserInfoKey = "0.25";
    UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 0}}";
    UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 568}";
    UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 568}";
    UIKeyboardFrameBeginUserInfoKey = "NSRect: {{inf, inf}, {0, 0}}";
    UIKeyboardFrameChangedByUserInteraction = 0;
    UIKeyboardFrameEndUserInfoKey = "NSRect: {{inf, inf}, {0, 0}}";
}

//WHEN PORTRAIR -> good values
Keyboard will show: {
    UIKeyboardAnimationCurveUserInfoKey = 7;
    UIKeyboardAnimationDurationUserInfoKey = "0.25";
    UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 216}}";
    UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 676}";
    UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 460}";
    UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 568}, {320, 216}}";
    UIKeyboardFrameChangedByUserInteraction = 0;
    UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 352}, {320, 216}}";
}

我正在使用UINavigationController，supportedInterfaceOrientations返回0。我需要它返回0，因为我手动旋转视图，如果我使用UIInterfaceOrientationX，视图旋转不能正常工作...

我所指的方向不是界面的方向，而是设备方向。（你拿着手机的方式）

编辑3：

只有当我在faceUP中推送一个新的ViewController时才会发生这种情况，如果我在portait中推送它，它的工作原理...... 并且需要知道的重要事项：当错误发生时，键盘不显示

编辑4：

我找到了修复错误的方法，但很可能被Apple拒绝：

objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationPortrait );

我仍然在寻找一个不会被Apple拒绝的解决方案

您可以检查状态栏方向并确定它是纵向还是横向，我正在使用此宏

#define IS_PORTRAIT UIInterfaceOrientationIsPortrait([UIApplication sharedApplication].statusBarOrientation)
