我愿知道如何利用核心学科框架提取填充的多功能。
例如,我试图引证:
我有A、B、C、D、E、F和G。
Can you suggest me ?
Thanks in advance.

- (void)drawRect:(CGRect)rect{
CGContextRef context= UIGraphicsGetCurrentContext();
CGContextSetRGBStrokeColor(context, 0.0, 1.0, 0.0, 1.0);
CGContextSetLineWidth(context, 1.0);
CGContextMoveToPoint(context, 10, 50);
CGContextAddLineToPoint(context, 100, 80);
CGContextAddLineToPoint(context, 120, 120);
CGContextAddLineToPoint(context, 60, 80);
CGContextAddLineToPoint(context, 10, 50);
CGContextSetFillColorWithColor(context, [UIColor redColor].CGColor);
CGContextFillPath(context);
}
也可通过<条码>做到这一点。 UIKit (i.e. 更高一级
UIBezierPath *path = [UIBezierPath ...];
...
[UIColor.redColor setFill];
[path fill];
这将填补您的当前图形背景。
