UIBezierpath 填充自定义形状答案

【问题描述】：

我试图填充这个形状。但是使用我的代码，它会填充整个视图，而不是内部形状。

UIBezierPath *shape = [UIBezierPath bezierPathWithRect:self.bounds];

[shape moveToPoint:CGPointMake(self.bounds.size.width*0.15, self.bounds.size.height*0.6)];

[shape addCurveToPoint:CGPointMake(self.bounds.size.width*0.85, self.bounds.size.height*0.4)
         controlPoint1:CGPointMake(self.bounds.size.width*0.1, self.bounds.size.height*0.3)
         controlPoint2:CGPointMake(self.bounds.size.width*0.6, self.bounds.size.height*0.5)];

[shape addCurveToPoint:CGPointMake(self.bounds.size.width*0.15, self.bounds.size.height*0.6)
         controlPoint1:CGPointMake(self.bounds.size.width*0.9, self.bounds.size.height*0.7)
         controlPoint2:CGPointMake(self.bounds.size.width*0.4, self.bounds.size.height*0.5)];
[shape closePath];
[[UIColor blueColor] setFill];
[shape fill];
[[UIColor brownColor] setStroke];
[shape stroke];

有什么问题？当我画三角形或任何其他形状时，它可以完美地工作。

【解决方案1】：

UIBezierPath *shape = [UIBezierPath bezierPathWithRect:self.bounds];

这就是问题所在。您正在创建具有视图边界的路径。请改用UIBezierPath *shape = [[UIBezierPath alloc] init];。

【解决方案2】：

试试这个：

我想你只会得到那个形状......

UIBezierPath *shape = [[UIBezierPath alloc] init];

[shape moveToPoint:CGPointMake(45,78)];

[shape addCurveToPoint:CGPointMake(67,51)
         controlPoint1:CGPointMake(43,78)
         controlPoint2:CGPointMake(55,54)];

[shape addCurveToPoint:CGPointMake(144,45)
         controlPoint1:CGPointMake(80,49)
         controlPoint2:CGPointMake(137,60)];

[shape addCurveToPoint:CGPointMake(143,77)
         controlPoint1:CGPointMake(157,34)
         controlPoint2:CGPointMake(143,77)];

[shape addCurveToPoint:CGPointMake(43,84)
         controlPoint1:CGPointMake(143,77)
         controlPoint2:CGPointMake(43,65)];

[shape addCurveToPoint:CGPointMake(43,78)
         controlPoint1:CGPointMake(43,103)
         controlPoint2:CGPointMake(43,78)];
[shape closePath];
[[UIColor blueColor] setFill];
[shape fill];
[[UIColor brownColor] setStroke];
shape.lineWidth = 1;
[shape stroke];

改变 CGPoint 取决于你的形状....

如果还有更多的困惑，试试这个工具并通过绘制形状来获取你的代码......
