如何在旋转了的试图中,使keyboard的方向正确?

设置当前statusbar的方向即可:

- (void)viewWillAppear: (BOOL)animated    // Called when the view is about to made visible. Default does nothing

{

    [[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];

    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:YES];

}
