第iOS開發(fā)之如何給View添加指定位置的邊框線詳解前言

本文主要給大家介紹了關(guān)于iOS如何給View添加指定位置邊框線的相關(guān)內(nèi)容，分享出來供大家參考學(xué)習(xí)，下面話不多說了，來一起看看詳細(xì)的介紹吧。

略微封裝了一下，給View添加指定位置的邊框線，其中位移枚舉的使用詢問了哥們兒，總算搞定；

示例代碼

封裝一：直接封裝成了一個(gè)方法

///邊框類型(位移枚舉)

typedefNS_ENUM(NSInteger,UIBorderSideType){

UIBorderSideTypeAll=0,

UIBorderSideTypeTop=10,

UIBorderSideTypeBottom=11,

UIBorderSideTypeLeft=12,

UIBorderSideTypeRight=13,

設(shè)置view指定位置的邊框

@paramoriginalView原view

@paramcolor邊框顏色

@paramborderWidth邊框?qū)挾?/p>

@paramborderType邊框類型例子:UIBorderSideTypeTop|UIBorderSideTypeBottom

@returnview

-(UIView*)borderForView:(UIView*)originalViewcolor:(UIColor*)colorborderWidth:(CGFloat)borderWidthborderType:(UIBorderSideType)borderType{

if(borderType==UIBorderSideTypeAll){

originalView.layer.borderWidth=borderWidth;

originalView.layer.borderColor=color.CGColor;

returnoriginalView;

///線的路徑

UIBezierPath*bezierPath=[UIBezierPathbezierPath];

///左側(cè)

if(borderTypeUIBorderSideTypeLeft){

///左側(cè)線路徑

[bezierPathmoveToPoint:CGPointMake(0.0f,originalView.frame.size.height)];

[bezierPathaddLineToPoint:CGPointMake(0.0f,0.0f)];

///右側(cè)

if(borderTypeUIBorderSideTypeRight){

///右側(cè)線路徑

[bezierPathmoveToPoint:CGPointMake(originalView.frame.size.width,0.0f)];

[bezierPathaddLineToPoint:CGPointMake(originalView.frame.size.width,originalView.frame.size.height)];

///top

if(borderTypeUIBorderSideTypeTop){

///top線路徑

[bezierPathmoveToPoint:CGPointMake(0.0f,0.0f)];

[bezierPathaddLineToPoint:CGPointMake(originalView.frame.size.width,0.0f)];

///bottom

if(borderTypeUIBorderSideTypeBottom){

///bottom線路徑

[bezierPathmoveToPoint:CGPointMake(0.0f,originalView.frame.size.height)];

[bezierPathaddLineToPoint:CGPointMake(originalView.frame.size.width,originalView.frame.size.height)];

CAShapeLayer*shapeLayer=[CAShapeLayerlayer];

shapeLayer.strokeColor=color.CGColor;

shapeLayer.fillColor=[UIColorclearColor].CGColor;

///添加路徑

shapeLayer.path=bezierPath.CGPath;

///線寬度

shapeLayer.lineWidth=borderWidth;

[originalView.layeraddSublayer:shapeLayer];

returnoriginalView;

}

封裝二：封裝成了類別

.h內(nèi)容

#importUIKit/UIKit.h

typedefNS_OPTIONS(NSUInteger,UIBorderSideType){

UIBorderSideTypeAll=0,

UIBorderSideTypeTop=10,

UIBorderSideTypeBottom=11,

UIBorderSideTypeLeft=12,

UIBorderSideTypeRight=13,

@interfaceUIView(BorderLine)

-(UIView*)borderForColor:(UIColor*)colorborderWidth:(CGFloat)borderWidthborderType:(UIBorderSideType)borderType;

@end

.m內(nèi)容

#importUIView+BorderLine.h

@implementationUIView(BorderLine)

-(UIView*)borderForColor:(UIColor*)colorborderWidth:(CGFloat)borderWidthborderType:(UIBorderSideType)borderT
