我想在uiview中绘制多个UIBezierPath,具有不同的笔画和填充颜色.
这是代码
- (void)drawRect:(CGRect)rect {
context = UIGraphicsGetCurrentContext();
[[UIColor grayColor] setFill];
[[UIColor greenColor] setStroke];
UIBezierPath *aPath = [[UIBezierPath alloc] init];
[aPath moveToPoint:CGPointMake(227,34.25)];
[aPath addLineToPoint:CGPointMake(298.25,34.75)];
[aPath addLineToPoint:CGPointMake(298.5,82.5)];
[aPath addLineToPoint:CGPointMake(251,83)];
[aPath addLineToPoint:CGPointMake(251,67.5)];
[aPath addLineToPoint:CGPointMake(227.25,66.75)];
[aPath closePath];
aPath.lineWidth = 2;
[aPath fill];
[aPath stroke];
UIBezierPath* aPath2 = [[UIBezierPath alloc] init];
[aPath2 moveToPoint:CGPointMake(251.25,90.5)];
[aPath2 addLineToPoint:CGPointMake(250.75,83.25)];
[aPath2 addLineToPoint:CGPointMake(298.5,83)];
[aPath2 addLineToPoint:CGPointMake(298.5,90.25)];
[aPath2 closePath];
aPath2.lineWidth = 2;
[aPath2 fill];
[aPath2 stroke];
[paths addObject:aPath2];
问题是笔画和填充颜色是在当前上下文中设置的.
在同一个CGContextRef中可以用不同的颜色绘制不同的UIBezierPath吗？
或者我必须在单独的uiview中绘制每个UIBezierPath？
解决方法
你应该添加
[desiredStrokeColor setStroke]; [desiredFillColor setFill];
表明这些是在这种情况下必须进一步使用的新颜色.你每次打电话之前都应该这样做
[aNewPath fill]; [aNewPath stroke];
以便用这些颜色绘制路径.
不需要为每个贝塞尔路径使用新的视图.
