如何在UIViewcontroller（StoryBoard）内部向上移动模式UIView

Question

i've got a UIView, dragged of Object Library, inside of a UIViewcontroller created by StoryBoard.

Inside of this UIView, I put two Text Field to grab user name and password, and one button to log in.

How can I move only this View when the keyboard appears? I'm able to move the whole View Controller, but i can't find a solution to move only the View.

I just dragged one View of the Object Library, inside my Viewcontroller and created one Outlet in .h Viecontroller - @property (weak, nonatomic) IBOutlet UIView *contentView; and connected do this View, i'm in doubt too if I need to do something more to add the view to the project.

Thanks in advance!!

You have to subscribe for UIKeyboardWillShowNotification and UIKeyboardWillHideNotification . Then move modal view up when keyboard appears, down when keyboard hides.

Then animate modal view up or down whether keyboard will show or hide:

Move up:

[UIView animateWithDuration:ANIMATION_DURATION animations:^{
    CGRect currentFrame = modalView.frame;
    currentFrame.origin.y -= VIEW_FRAME_OFFSET;
    modalView.frame = currentFrame;
}];

Move down:

[UIView animateWithDuration:ANIMATION_DURATION animations:^{
    CGRect currentFrame = modalView.frame;
    currentFrame.origin.y += VIEW_FRAME_OFFSET;
    modalView.frame = currentFrame;
}];

Also if you want you can use other keyboard notifications listed here .
