工作中我們常常碰到這樣的點擊按鈕颅停，實現(xiàn)方法有很多種，今天給大家介紹下我這邊使用UIButton titleEdgeInsets和imageEdgeInsets的實現(xiàn)方案富弦。

直接上代碼雾袱，方法調(diào)用前先設(shè)置圖片和文字

@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)

? ? ? ? }

? ? }
