I don't think that's a good a solution, but I'll post it. Any comments will be appreciated))
titleSize = button.titleLabel.frame.size;
button.imageEdgeInsets = UIEdgeInsetsMake(-titleSize.height, 0.0f, 0.0f, -titleSize.width);
[button setSize:CGSizeMake(titleSize.width, titleSize.height + imageSize.height)];
So, I've just set button size manually and that's how it looks now
Thank you
