UIBezierPath将矩形和弧绘制在一起

我想画一条这样的路径： 在此处输入图像描述

这就是我写的： 

CGFloat radius = 50; UIBezierPath *path = [UIBezierPath bezierPath]; [path moveToPoint:CGPointMake(radius, CGRectGetMinY(rect))]; [path addLineToPoint:CGPointMake(CGRectGetMaxX(rect) - radius, CGRectGetMinY(rect))]; [path addLineToPoint:CGPointMake(CGRectGetMaxX(rect) -radius, CGRectGetMaxY(rect))]; [path addLineToPoint:CGPointMake(radius, CGRectGetMaxY(rect))]; [path closePath]; UIBezierPath *path1 = [UIBezierPath bezierPathWithArcCenter:CGPointMake(radius, CGRectGetMinY(rect) + radius) radius:radius startAngle:0.5 * M_PI endAngle:1.5 *M_PI clockwise:YES]; UIBezierPath *path2 = [UIBezierPath bezierPathWithArcCenter:CGPointMake(CGRectGetMaxX(rect) - radius, CGRectGetMaxY(rect) - radius) radius:radius startAngle:-0.5 * M_PI endAngle:0.5 *M_PI clockwise:YES]; [path1 appendPath:path]; [path1 appendPath:path2];

所以我得到了这样的结果 结果

我怎么能删除这两个变形线？ 谢谢

试试这个： 

 - (void)drawRect:(CGRect)rect{ CGContextRef context = UIGraphicsGetCurrentContext(); const CGFloat radius = 50; const CGFloat lineWidth = 10; UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:CGRectInset(rect, lineWidth / 2, lineWidth / 2) cornerRadius:radius]; CGContextSetStrokeColorWithColor(context, [UIColor whiteColor].CGColor); path.lineWidth = lineWidth; [path stroke]; CGContextSetFillColorWithColor(context, [UIColor grayColor].CGColor); [path fill]; }

在此处输入图像描述

您可以像这样实现自定义视图： 

 @interface RoundedView: UIView @property (nonatomic, strong) UIColor *strokeColor; @property (nonatomic, strong) UIColor *fillColor; @end @implementation RoundedView - (instancetype)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { self.backgroundColor = [UIColor clearColor]; } return self; } -(void)drawRect:(CGRect)rect{ CGContextRef context = UIGraphicsGetCurrentContext(); const CGFloat radius = 50; const CGFloat lineWidth = 10; UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:CGRectInset(rect, lineWidth / 2, lineWidth / 2) cornerRadius:radius]; CGContextSetStrokeColorWithColor(context, self.strokeColor.CGColor); path.lineWidth = lineWidth; [path stroke]; CGContextSetFillColorWithColor(context, self.fillColor.CGColor); [path fill]; } @end

然后使用它： 

 RoundedView *view = [[RoundedView alloc] initWithFrame:CGRectMake(10, 20, 200, 100)]; [self.view addSubview:view];

这是你需要的，只需要调整它： 

 - (void)drawSkateboard: (CGRect)frame { UIColor* fillColor = [UIColor colorWithRed: 0 green: 0 blue: 0 alpha: 1]; UIBezierPath* bezierPath = UIBezierPath.bezierPath; [bezierPath moveToPoint: CGPointMake(CGRectGetMinX(frame) + 529, CGRectGetMinY(frame) + 414)]; [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 207, CGRectGetMinY(frame) + 414)]; [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame), CGRectGetMinY(frame) + 207) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 93.2, CGRectGetMinY(frame) + 414) controlPoint2: CGPointMake(CGRectGetMinX(frame), CGRectGetMinY(frame) + 320.9)]; [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame), CGRectGetMinY(frame) + 207)]; [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 207, CGRectGetMinY(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame), CGRectGetMinY(frame) + 93.2) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 93.1, CGRectGetMinY(frame))]; [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 529, CGRectGetMinY(frame))]; [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 736, CGRectGetMinY(frame) + 207) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 642.8, CGRectGetMinY(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 736, CGRectGetMinY(frame) + 93.1)]; [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 736, CGRectGetMinY(frame) + 207)]; [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 529, CGRectGetMinY(frame) + 414) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 736, CGRectGetMinY(frame) + 320.9) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 642.9, CGRectGetMinY(frame) + 414)]; [bezierPath closePath]; bezierPath.miterLimit = 4; [fillColor setFill]; [bezierPath fill]; }

这是为了横向Iphone 6+尺寸，它产生这个：

在此处输入图像描述

我将它调整为全屏，以便通过使用整个屏幕边界的百分比和分区来调整它的大小，但这只是一个例子，就是这样。 我会再发一些。

这是另一个，这个与你拥有的非常匹配，这也适用于iphone 6+，全屏宽度，你只需按照（所需高度）*（（[UIScreen mainScreen]的比率）进行数字划分。 bounds.height）/（736））然后对宽度数字做同样的事情，但显然宽度，这将从iphone 6+向上和向下resize 

 - (void)drawSkateboard: (CGRect)frame { UIColor* color = [UIColor colorWithRed: 0.451 green: 0.416 blue: 1 alpha: 1]; UIBezierPath* bezierPath = UIBezierPath.bezierPath; [bezierPath moveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.87704 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.71739 * CGRectGetHeight(frame))]; [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 0.12296 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.71739 * CGRectGetHeight(frame))]; [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.00000 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.49879 * CGRectGetHeight(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 0.05530 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.71739 * CGRectGetHeight(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 0.00000 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.61908 * CGRectGetHeight(frame))]; [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 0.00000 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.49879 * CGRectGetHeight(frame))]; [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.12296 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.28019 * CGRectGetHeight(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 0.00000 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.37850 * CGRectGetHeight(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 0.05530 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.28019 * CGRectGetHeight(frame))]; [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 0.87704 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.28019 * CGRectGetHeight(frame))]; [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 1.00000 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.49879 * CGRectGetHeight(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 0.94470 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.28019 * CGRectGetHeight(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 1.00000 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.37850 * CGRectGetHeight(frame))]; [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 1.00000 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.49879 * CGRectGetHeight(frame))]; [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.87704 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.71739 * CGRectGetHeight(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 1.00000 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.61908 * CGRectGetHeight(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 0.94470 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.71739 * CGRectGetHeight(frame))]; [bezierPath closePath]; bezierPath.miterLimit = 4; [color setFill]; [bezierPath fill]; }

灰色背景，iphone 6+屏幕，白色边框，与您发布的尺寸相同：

并且，最重要的是，这是一个类别，这是非常好的，你插入你的数字，并presto你已完成：
