UIBezierPath将矩形和圆弧绘制在一起

Question

我想画一条这样的路径：

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

我怎么能删除这两条新生的线？感谢

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];
}

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];
}

这适用于Iphone 6+尺寸，它产生了这个：

我将其调整为全屏，以便您通过使用整个屏幕边界的百分比和分区来调整大小以满足您的需要，但这只是一个示例，就是这样。我会发布一些。

这是另一个，这个与你拥有的非常匹配，这个尺寸也适用于iphone 6+，全屏宽度，你只需按照（所需高度）*的比例进行数字划分（（[UIScreen] mainScreen] .bounds.height）/（736））然后对宽度数字做同样的事情，但宽度明显，这将从iphone 6+向下调整大小

- (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，与您发布的尺寸相同：

- (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：

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，然后你就完成了：

#define TOP_LEFT(X, Y)\
    CGPointMake(rect.origin.x + X * limitedRadius,\
                rect.origin.y + Y * limitedRadius)
#define TOP_RIGHT(X, Y)\
    CGPointMake(rect.origin.x + rect.size.width - X * limitedRadius,\
                rect.origin.y + Y * limitedRadius)
#define BOTTOM_RIGHT(X, Y)\
    CGPointMake(rect.origin.x + rect.size.width - X * limitedRadius,\
