iOS UIButton 图文上下布局

继承UIButton类创建
在.m中添加方法

- (void)layoutButtonWithImageTitleSpace:(CGFloat)space {
    CGFloat imageWith = self.imageView.image.size.width;
    CGFloat imageHeight = self.imageView.image.size.height;
    CGFloat labelWidth = self.titleLabel.intrinsicContentSize.width;
    CGFloat labelHeight = self.titleLabel.intrinsicContentSize.height;
    
    UIEdgeInsets imageEdgeInsets = UIEdgeInsetsMake(-labelHeight-space/2.0, 0, 0, -labelWidth);
    UIEdgeInsets labelEdgeInsets = UIEdgeInsetsMake(0, -imageWith, -imageHeight-space/2.0, 0);
    self.titleEdgeInsets = labelEdgeInsets;
    self.imageEdgeInsets = imageEdgeInsets;
}

在需要的时候调用后，Button会改为上下布局
