我想填充形状的内部,但没有用处。它只是描绘路径,但不填充你好颜色。我GOOGLE了,但没有作为填充不工作。指导我做错了什么。填充内部的路径保持线宽可见
CGContextRef ctx = UIGraphicsGetCurrentContext();
CGContextAddPath(ctx, pathi);
CGContextSetStrokeColorWithColor(ctx, [UIColor redColor].CGColor);
CGContextSetFillColorWithColor(ctx, [UIColor yellowColor].CGColor);
CGContextSetLineWidth(ctx, 3.0);
CGContextSetLineCap(ctx, kCGLineCapSquare);
CGContextSetAllowsAntialiasing(ctx, NO);
// CGContextStrokePath(ctx);
CGContextDrawPath(ctx, kCGPathFillStroke);
编辑:为伯提的代码是
- (CGMutablePathRef)getPath {
if (self.shapeType == NOSHAPE) {
return nil;
}
[lineHeight removeAllObjects];
[linesArray removeAllObjects];
CGMutablePathRef path = CGPathCreateMutable();
switch (self.shapeType) {
case Rectangle_SHAPE:{
Line *l1 = [[Line alloc] initWithLineName:LineName_a_S
starttPoint:self.bound.origin
endPoint:CGPointMake(self.bound.size.width, self.bound.origin.y) scalingFactor:1.0
linePosition:LINE_DIRECTION_HORIZONTAL];
[lineHeight addObject:[NSNumber numberWithFloat:l1.lineLength]];
[linesArray addObject:l1];
Line *l2 = [[Line alloc] initWithLineName:LineName_c_S
starttPoint:CGPointMake(self.bound.size.width, self.bound.origin.y)
endPoint:CGPointMake(self.bound.size.width, self.bound.size.height) scalingFactor:1.0
linePosition:LINE_DIRECTION_VERTICAL];
[lineHeight addObject:[NSNumber numberWithFloat:l2.lineLength]];
[linesArray addObject:l2];
Line *l3 = [[Line alloc] initWithLineName:LineName_b_S
starttPoint:CGPointMake(self.bound.size.width, self.bound.size.height)
endPoint:CGPointMake(self.bound.origin.x, self.bound.size.height) scalingFactor:1.0
linePosition:LINE_DIRECTION_HORIZONTAL];
[lineHeight addObject:[NSNumber numberWithFloat:l3.lineLength]];
[linesArray addObject:l3];
Line *l4 = [[Line alloc] initWithLineName:LineName_d_S
starttPoint:CGPointMake(self.bound.origin.x, self.bound.size.height)
endPoint:self.bound.origin scalingFactor:1.0
linePosition:LINE_DIRECTION_VERTICAL];
[lineHeight addObject:[NSNumber numberWithFloat:l4.lineLength]];
[linesArray addObject:l4];
CGPathAddPath(path, NULL, [l1 getPath]);
CGPathAddPath(path, NULL, [l2 getPath]);
CGPathAddPath(path, NULL, [l3 getPath]);
CGPathAddPath(path, NULL, [l4 getPath]);
[l1 release];
[l2 release];
[l3 release];
[l4 release];
break;
}
default:
break;
}
return path;
}
我也创造其他形状和路径在相同的方式进行。 行类给我从开始和结束点的线。请告诉我,如果有什么我失踪。
你在看什么?只有红色的轮廓? (你实际看到的图像+预计可能会有用) –
只是红色的轮廓。 – fibnochi
我试过了,我能够得到边框并使用相同的代码分隔填充颜色。我用这个为你的“pathi” CGPathRef pathi = CGPathCreateWithEllipseInRect(CGRectMake(0,0,100,100),nil); 现在我的猜测是要么你的路径不是一个大的矩形,或者你正在使用较大的值的宽度大小,这是隐藏你的填充颜色。 –
