普通下划线可以，但虚线下划线似乎不起作用？UIButton*btn=[UIButtonbuttonWithType:UIButtonTypeCustom];btn.frame=CGRectMake(100,10,300,300);NSMutableAttributedString*titleString=[[NSMutableAttributedStringalloc]initWithString:@"DurgaVundavalli"];//makingtextpropertytounderlinetext-[titleStringaddAttribute:NSUnderlineSty
我正在从UIBezierPath创建一条虚线，如下所示:这是我用来构建和绘制路径的代码:constCGContextRefcontext=UIGraphicsGetCurrentContext();constCGSizevisibleSize=CGSizeMake(self.width-(kIndent*2),self.height-(kIndent*2));UIBezierPath*borderPath=[UIBezierPathbezierPathWithRoundedRect:CGRectMake(kIndent,kIndent,visibleSize.width,visible
我想在我的UITableViewCell中添加一个虚线底部边框。目前，我正在使用以下代码，CAShapeLayer*border=[CAShapeLayerlayer];border.strokeColor=[UIColorcolorWithRed:67/255.0fgreen:37/255.0fblue:83/255.0falpha:1].CGColor;border.fillColor=nil;border.lineDashPattern=@[@1,@1];border.path=[UIBezierPathbezierPathWithRect:cell.bounds].CGPath
CAShapeLayer*circle=[CAShapeLayerlayer];circle.path=[UIBezierPathbezierPathWithRoundedRect:CGRectMake(0,0,2.0*radius,2.0*radius)cornerRadius:radius].CGPath;//Configuretheapperenceofthecirclecircle.fillColor=[UIColorclearColor].CGColor;circle.strokeColor=[UIColorwhiteColor].CGColor;circle.lineWid
我想在我的spritekit游戏中画一条虚线，我可以使用SKShapeNode节点画一条法线，如下所示:UIBezierPath*_path=[UIBezierPathbezierPath];//1CGPointpoint1=CGPointMake(100,100);CGPointpoint2=CGPointMake(150,150);[_pathmoveToPoint:point1];[_pathaddLineToPoint:point2];//2SKShapeNode*line=[SKShapeNodenode];line.path=_path.CGPath;我尝试像这样为UIBe
我想为我的UITextField和UITextView设置一个点线/虚线边框。我该怎么做？我知道，我可以用这行代码设置边框:[self.textFieldCardTitle.layersetBorderWidth:1.0];[self.textFieldCardTitle.layersetBorderColor:[[UIColorwhiteColor]CGColor]];注意:我已经有了在UITextView后面添加一个UIImageView并在那里设置一个带虚线边框的图像的想法。但我不想那样解决。 最佳答案 例如，您可以尝试下一种
我正在ios中开发绘图功能，我有3种类型的线条飞机虚线点缀问题出在点线，当我画得很快时它画得很好，但当我画得慢时它画出实线下面是代码片段，请指导我哪里有问题。-(void)drawingLayerMoved:(UIPanGestureRecognizer*)recognizer{//MOVESTARTif(recognizer.state==UIGestureRecognizerStateBegan){dw_mouseSwiped=NO;dw_lastPoint=[recognizerlocationInView:self.tempDrawImage];UIGraphicsBeginI
我正在尝试使用CGContextSetLineDash绘制虚线。这是我的代码:floatdashPhase=0.0;floatdashLengths[]={30,30};CGContextSetLineDash(context,dashPhase,dashLengths,20.0);self.previousPoint2=self.previousPoint1;self.previousPoint1=previous;self.currentPoint=current;self.mid1=[selfpointBetween:self.previousPoint1andPoint:sel
我试过下面的代码，但它画的是直线，我想要虚线@IBOutletvarnavigationView:MGLMapView!varpolyline:MGLPolyline!overridefuncviewDidLoad(){super.viewDidLoad()varmapCoordinates:[CLLocationCoordinate2D]=[]letnewCoord1=CLLocationCoordinate2D(latitude:8.5241,longitude:76.9366)letnewCoord2=CLLocationCoordinate2D(latitude:11.8745
我正在尝试根据我找到的代码创建一个虚线Polylinehere-thirdanswer.我想到了这个://routeletpath=GMSMutablePath()//populatepathwithcoordinateshere//...letroute=GMSPolyline(path:path)route.strokeWidth=3.0letstyles=[GMSStrokeStyle.solidColor(UIColor(red:0.945,green:0.392,blue:0.278,alpha:1.0)),GMSStrokeStyle.solidColor(UIColor.
