工作中我们常常碰到这样的点击按钮，实现方法有很多种，今天给大家介绍下我这边使用UIButton titleEdgeInsets和imageEdgeInsets的实现方案。

直接上代码，方法调用前先设置图片和文字

@objcfuncchangeImageTitleLocation(type: ChangeButtonImageLocationType,distance:  CGFloat)  {

        layoutIfNeeded()

        letbtnWidth =frame.width

        letbtnHeight =frame.height

        letimageFrame =imageRect(forContentRect:CGRect(x:0,y:0,width:  btnWidth,height: btnHeight))

        lettitleFrame =titleRect(forContentRect:CGRect(x:0,y:0,width: btnWidth,height: btnHeight))

        iftype == .top|| type == .bottom{

            lettitleDistance =  (btnWidth-titleFrame.width)/2- titleFrame.origin.x

            letimageDistance = (btnWidth-imageFrame.width)/2- imageFrame.origin.x

            iftype == .top{

                lettitleHDistance =  (btnHeight + imageFrame.size.height- titleFrame.size.height+ distance)/2- titleFrame.origin.y

                letimageHDistance = (btnHeight - imageFrame.size.height- titleFrame.size.height- distance)/2- imageFrame.origin.y

                titleEdgeInsets=UIEdgeInsets(top: titleHDistance,left: titleDistance,bottom: -titleHDistance,right: -titleDistance)

                imageEdgeInsets=UIEdgeInsets(top: imageHDistance,left: imageDistance,bottom: -imageHDistance,right: -imageDistance)

            }else{

                lettitleHDistance =  (btnHeight - imageFrame.size.height- titleFrame.size.height- distance)/2- titleFrame.origin.y

                letimageHDistance = (btnHeight - imageFrame.size.height+ titleFrame.size.height+ distance)/2- imageFrame.origin.y

                titleEdgeInsets=UIEdgeInsets(top: titleHDistance,left: titleDistance,bottom: -titleHDistance,right: -titleDistance)

                imageEdgeInsets=UIEdgeInsets(top: imageHDistance,left: imageDistance,bottom: -imageHDistance,right: -imageDistance)

            }

        }elseiftype == .right{

            lettitleDistance =  (btnWidth-titleFrame.width-imageFrame.width-distance)/2- titleFrame.origin.x

            letimageDistance =  (btnWidth+titleFrame.width-imageFrame.width+distance)/2- imageFrame.origin.x

            titleEdgeInsets=UIEdgeInsets(top:0,left: titleDistance,bottom:0,right: -titleDistance)

            imageEdgeInsets=UIEdgeInsets(top:0,left: imageDistance,bottom:0,right: -imageDistance)

        }else{

            lettitleDistance =  (btnWidth-titleFrame.width+imageFrame.width+distance)/2- titleFrame.origin.x

            letimageDistance =  (btnWidth-titleFrame.width-imageFrame.width-distance)/2- imageFrame.origin.x

            titleEdgeInsets=UIEdgeInsets(top:0,left: titleDistance,bottom:0,right: -titleDistance)

            imageEdgeInsets=UIEdgeInsets(top:0,left: imageDistance,bottom:0,right: -imageDistance)

        }

    }
