iOS 同时画虚线和直线

- (void)drawRect:(CGRect)rect {
    [super drawRect:rect];
    
    CGFloat y1 = _textField.bottom;
    CGFloat y2 = _monthPayLabel.bottom;
    
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetStrokeColorWithColor(context, UIColorFromRGB(0xd7dadf).CGColor);
    
    //画两根线，虚线
    CGContextSetLineWidth(context,1);//线宽度
    CGFloat lengths[] = {10,5};//先画4个点再画2个点
    CGContextSetLineDash(context, 0, lengths, 2);
    CGContextMoveToPoint(context, AutoSize(12), y1);
    CGContextAddLineToPoint(context, SCREEN_WIDTH, y1);
    CGContextStrokePath(context);
    //实线
    CGContextSetLineDash(context, 0, NULL, 0);
    CGContextMoveToPoint(context, AutoSize(12), y2);
    CGContextAddLineToPoint(context, SCREEN_WIDTH, y2);
    CGContextStrokePath(context);
    
    CGContextClosePath(context);
