UIKeyboardBoundsUserInfoKey已弃用

Question

我正在尝试使用下面的代码，但Xcode告诉我UIKeyboardBoundsUserInfoKey已被弃用，我想知道更新的代码是什么：

NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];

以下是上下文中的代码：

-(void) keyboardDidHide: (NSNotification *)notif {


    NSDictionary* info = [notif userInfo];
    NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
    CGSize keyboardSize = [aValue CGRectValue].size;
    CGRect viewFrame = self.view.frame; 
    viewFrame.size.height += keyboardSize.height;
    scrollView.frame = viewFrame;

    if (!keyboardVisible) {
        //NSLog(@"Keyboard is already hidden. Ignoring notification.");
        return;
    }

    keyboardVisible = NO;

}

您可以使用UIKeyboardFrameBeginUserInfoKey或UIKeyboardFrameEndUserInfoKey键代替UIKeyboardBoundsUserInfoKey。
