UIButton实现左文字右图片
[priceBtnsetTitleEdgeInsets: UIEdgeInsetsMake (0, -priceBtn.imageView.size.width, 0, priceBtn.imageView.size.width)];
[priceBtnsetImageEdgeInsets: UIEdgeInsetsMake (0, priceBtn.titleLabel.bounds.size.width, 0, -priceBtn.titleLabel.bounds.size.width)];
UIButton实现上图下文字
CGSizeimageSize = collectBtn.imageView.frame.size;
CGSizetitleSize = collectBtn.titleLabel.frame.size;
// 图文间隔
CGFloatspacing = 5;
CGFloattotalHeight = (imageSize.height + titleSize.height + spacing);
collectBtn.imageEdgeInsets = UIEdgeInsetsMake( - (totalHeight - imageSize.height), 0.0, 0.0, -titleSize.width);
collectBtn.titleEdgeInsets = UIEdgeInsetsMake(0.0, - imageSize.width, -(totalHeight - titleSize.height), 0.0);
