UIButton扩展一个方法:
spacing 图片和文字的间隔
- (void)verticalImageAndTitle:(CGFloat)spacing
{
CGSize imageSize = self.imageView.frame.size;
CGSize titleSize = self.titleLabel.frame.size;
CGSize textSize = [self.titleLabel.text sizeWithFont:self.titleLabel.font];
CGSizeframeSize =CGSizeMake(ceilf(textSize.width),ceilf(textSize.height));
if(titleSize.width+0.5< frameSize.width) {
titleSize.width= frameSize.width;
}
CGFloattotalHeight = (imageSize.height+ titleSize.height+ spacing);
self.imageEdgeInsets=UIEdgeInsetsMake(- (totalHeight - imageSize.height),0.0,0.0, - titleSize.width);
self.titleEdgeInsets=UIEdgeInsetsMake(0, - imageSize.width, - (totalHeight - titleSize.height),0);
}
