- self.pregress = [[CAShapeLayer alloc]init];
- _pregress.frame = CGRectMake(15,18, 64,64);
- _pregress.lineWidth= 3;
- _pregress.fillColor= [UIColor colorWithWhite:0 alpha:0].CGColor;
- _pregress.strokeColor = RGBCOLOR(225,140,150).CGColor;
- _pregress.lineCap = @"round";
- _pregress.strokeStart = 0;
- _pregress.strokeEnd = 0;
-
- _pregress.path = CGPathCreateWithEllipseInRect(pregress_bg.bounds, NULL);
- _pregress.transform = CATransform3DMakeRotation(M_PI, 0, 0, 1);
- [self.layer addSublayer:_pregress];
