由于本人比較懶，很少寫博客彼乌，由于一個(gè)朋友公司需要實(shí)現(xiàn)下面這個(gè)等級(jí)效果，自己也閑來無聊渊迁，就用UIBezierPath實(shí)現(xiàn)了慰照，并做個(gè)記錄。直接上代碼吧
//創(chuàng)建貝塞爾路徑
UIBezierPath *path = [UIBezierPath bezierPathWithArcCenter:CGPointMake(centerX, centerY) radius:radius startAngle:(0.5f*M_PI) endAngle:2.5f*M_PI clockwise:YES];
//添加背景圓環(huán)
CAShapeLayer *backLayer = [CAShapeLayer layer];
backLayer.frame = self.bounds;
backLayer.fillColor =? [[UIColor clearColor] CGColor];
backLayer.strokeColor? = [UIColor colorWithRed:26.0/255.0f green:126.0/255.0f blue:255.0/255.0f alpha:1].CGColor;
backLayer.lineWidth = _lineWidth;
backLayer.path = [path CGPath];
backLayer.strokeEnd = 1;
[self.layer addSublayer:backLayer];
//設(shè)置漸變顏色
CAGradientLayer *gradientLayer =? [CAGradientLayer layer];
gradientLayer.frame = self.bounds;
[gradientLayer setColors:[NSArray arrayWithObjects:(id)[RGB(63, 204, 132) CGColor],(id)[RGB(98, 254, 52) CGColor], nil]];
gradientLayer.startPoint = CGPointMake(0, 0);
gradientLayer.endPoint = CGPointMake(0, 1);
[gradientLayer setMask:_proLayer]; //用progressLayer來截取漸變層
[self.layer addSublayer:gradientLayer];
//添加火柴棍
