This should be a simple one, basically I have a few paths drawn with core graphics, and I want to be able to rotate them (for convenience). I've tried using CGContextRotateCTM(context); but it's not rotating anything. Am I missing something?
Here's the source for drawRect
- (void)drawRect:(CGRect)rect {
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetLineWidth(context, 1.5);
CGContextSetStrokeColorWithColor(context, [UIColor whiteColor].CGColor);
CGContextSetShadow(context, CGSizeMake(0, 1), 0);
CGContextBeginPath(context);
CGContextMoveToPoint(context, 13.5, 13.5);
CGContextAddLineToPoint(context, 30.5, 13.5);
CGContextAddLineToPoint(context, 30.5, 30.5);
CGContextAddLineToPoint(context, 13.5, 30.5);
CGContextAddLineToPoint(context, 13.5, 13.5);
CGContextClosePath(context);
CGContextMoveToPoint(context, 26.2, 13.5);
CGContextAddLineToPoint(context, 26.2, 17.8);
CGContextAddLineToPoint(context, 30.5, 17.8);
CGContextMoveToPoint(context, 17.8, 13.5);
CGContextAddLineToPoint(context, 17.8, 17.8);
CGContextAddLineToPoint(context, 13.5, 17.8);
CGContextMoveToPoint(context, 13.5, 26.2);
CGContextAddLineToPoint(context, 17.8, 26.2);
CGContextAddLineToPoint(context, 17.8, 30.5);
CGContextStrokePath(context);
CGContextSetFillColorWithColor(context, [UIColor whiteColor].CGColor);
CGContextSetShadowWithColor(context, CGSizeMake(0, 0), 0, [UIColor clearColor].CGColor);
CGContextFillRect(context, CGRectMake(26.2, 13.5, 4.3, 4.3));
CGContextFillRect(context, CGRectMake(13.5, 13.5, 4.3, 4.3));
CGContextFillRect(context, CGRectMake(13.5, 26.2, 4.3, 4.3));
CGContextRotateCTM(context, M_PI / 4);
}
