UIBezierPath 一起绘制矩形和圆弧

Question

我想这样画一条路：

这是我写的：

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

那两条多余的线怎么去掉？谢谢

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];
}

这是一个风景 Iphone 6+ 大小，它产生这个：

我将它的大小设置为全屏，以便您可以根据需要使用整个屏幕边界的百分比和分区来调整它的大小，但这只是一个示例，仅此而已。我再 post 几个。

这是另一个，这个与你所拥有的非常匹配，它的大小也适合 iphone 6+，全屏宽度，你只需按（所需高度）的比例对数字进行除法)*(([UIScreen mainScreen].bounds.height)/(736)) 然后对宽度数字执行相同的操作，但宽度明显，这将从 iphone 6+ 上下调整

- (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];
}

结果：

灰色背景，iphone 6+ 屏幕，白色边框，与您post编辑的尺寸相同：

- (void)drawSkateboard: (CGRect)frame  {
    UIBezierPath* rectanglePath = [UIBezierPath bezierPathWithRect: CGRectMake(CGRectGetMinX(frame), CGRectGetMinY(frame), 736, 414)];
    [UIColor.lightGrayColor setFill];
    [rectanglePath fill];

    UIBezierPath* bezierPath = UIBezierPath.bezierPath;
    [bezierPath moveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.82853 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.69300 * CGRectGetHeight(frame))];
    [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 0.17147 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.69300 * CGRectGetHeight(frame))];
    [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.06291 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.50000 * CGRectGetHeight(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 0.11182 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.69300 * CGRectGetHeight(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 0.06291 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.60628 * CGRectGetHeight(frame))];
    [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 0.06291 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.50000 * CGRectGetHeight(frame))];
    [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.17147 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.30700 * CGRectGetHeight(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 0.06291 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.39396 * CGRectGetHeight(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 0.11168 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.30700 * CGRectGetHeight(frame))];
    [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 0.82853 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.30700 * CGRectGetHeight(frame))];
    [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.93709 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.50000 * CGRectGetHeight(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 0.88818 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.30700 * CGRectGetHeight(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 0.93709 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.39372 * CGRectGetHeight(frame))];
    [bezierPath addLineToPoint: CGPointMake(CGRectGetMinX(frame) + 0.93709 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.50000 * CGRectGetHeight(frame))];
    [bezierPath addCurveToPoint: CGPointMake(CGRectGetMinX(frame) + 0.82853 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.69300 * CGRectGetHeight(frame)) controlPoint1: CGPointMake(CGRectGetMinX(frame) + 0.93709 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.60604 * CGRectGetHeight(frame)) controlPoint2: CGPointMake(CGRectGetMinX(frame) + 0.88818 * CGRectGetWidth(frame), CGRectGetMinY(frame) + 0.69300 * CGRectGetHeight(frame))];
    [bezierPath closePath];
    bezierPath.miterLimit = 4;

    [UIColor.blueColor setFill];
    [bezierPath fill];
    [UIColor.whiteColor setStroke];
    bezierPath.lineWidth = 5.5;
    [bezierPath stroke];
}

结果：

而且，最重要的是，这是一个类别，这非常好，你输入你的数字，然后你就完成了：

    CGPointMake(rect.origin.x + X * limitedRadius,\
                rect.origin.y + Y * limitedRadius)

Answer 2

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];
}

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];
