我已经使用此代码创建了自定义圆形视图
//Color Declaration
UIColor *color = [UIColor colorWithRed:0 green:0.429 blue:0 alpha:1];
//Drawing Circle
CGRect circleRect = CGRectMake(20, 20, 170, 170);
UIBezierPath *circlePath = [UIBezierPath bezierPath];
[circlePath addArcWithCenter:CGPointMake(CGRectGetMidX(circleRect), CGRectGetMidY(circleRect))
radius:CGRectGetWidth(circleRect)/2 startAngle:0 * M_PI/180
endAngle:289 * M_PI/180
clockwise:YES];
[circlePath addLineToPoint:CGPointMake(CGRectGetMidX(circleRect), CGRectGetMidY(circleRect))];
[circlePath closePath];
[color setFill];
[circlePath fill];
我的要求是我必须使用手柄重新调整起始角度和结束角度的大小。如何在圆圈周围创建句柄..?如何使用触摸移动手柄
