我需要根据这个设计实现进度条:
如您所见,酒吧本身有一个角半径。
这就是我现在使用的代码:
那么,该怎么做? 这是我目前的代码:
- (void)animateProgressBarToPercent:(float)percent
{
if (percent > 1.0f) return;
int radius = 42.7f;
int strokeWidth = 7.f;
CGColorRef color = [UIColor someColor].CGColor;
int timeInSeconds = percent * 5;
CGFloat startAngle = 0;
CGFloat endAngle = percent;
CAShapeLayer *circle = [CAShapeLayer layer];
circle.path = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(0, 0, 2.0*radius, 2.0*radius) cornerRadius:radius].CGPath;
circle.position = CGPointMake(self.center.x - radius, self.center.y + strokeWidth);
circle.fillColor = [UIColor clearColor].CGColor;
circle.strokeColor = color;
circle.lineWidth = strokeWidth;
circle.strokeEnd = endAngle;
[self.layer addSublayer:circle];
CABasicAnimation *drawAnimation = [CABasicAnimation animationWithKeyPath:@"strokeEnd"];
drawAnimation.duration = timeInSeconds;
drawAnimation.repeatCount = 1.0;
drawAnimation.removedOnCompletion = NO;
drawAnimation.fromValue = [NSNumber numberWithFloat:startAngle];
drawAnimation.toValue = [NSNumber numberWithFloat:endAngle];
drawAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
[circle addAnimation:drawAnimation forKey:@"drawCircleAnimation"];
}

Morris.Area({

{ day: "Fri", Reward: 2, Redeem: 0 },
{ day: "Sat", Reward: 1, Redeem: 0 },
{ day: "Sun", Reward: 0, Redeem: 0 },

],

ykeys: ['Reward', 'Redeem'],

hideHover: 'auto',

只需设置circle.lineCap = kCALineCapRound
