If you are using AutoLayout try to layout your subviews manually. For me my keyboard appeared instantly without delay when i quitted AutoLayout. Before I had I had a delay of about one second.

For example:
first row of keyboard: q w e r t z u i o p
q had a leading space of 15 px
p had a trailing space of 15 px
q w e r t z u i o p had a spacing of 5 px and they had the same width

Instead of using constraints, you can easily code it yourself in layoutSubviews of your views KeyboardViewController:

    NSUInteger numberOfRows = 4;
    CGFloat horizontalSpacing = 5.0;
    CGFloat verticalSpacing = 12.0;
    CGFloat leadingSpacingFirstRow = 3.0;
    CGFloat trailingSpacingFirstRow = 3.0;
    CGFloat topPadding = 25.0;
    CGFloat bottomPadding = 3.0;
    CGFloat width = ( self.bounds.size.width - leadingSpacingFirstRow - trailingSpacingFirstRow - horizontalSpacing * (numberOfButtonsFirstRow - 1) ) / numberOfButtonsFirstRow;
    CGFloat height = ( self.bounds.size.height - topPadding - bottomPadding - verticalSpacing * (numberOfRows - 1) ) / numberOfRows;

Now you can place the buttons in your view:

    // create row 1
    for (NSUInteger i=0; i<numberOfButtonsFirstRow; i++) {
        UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(leadingSpacingFirstRow + i * width + i * horizontalSpacing, topPadding, width, height)];

        [self addSubview:v];
    }
