I have these 2 methods in the View class. the drawRect method always gets called when the view is initalized. But i can't get the drawLine method to work. It doesn't do anything when it gets called. Am i supposed to deal with cgimagecontext or something like that? please help!!
(void)drawRect:(CGRect)rect {
// Drawing code
// Drawing code
CGContextRef contextRef = UIGraphicsGetCurrentContext();
//CGContextSetRGBFillColor(contextRef, 0, 0, 255, 1);
CGContextSetRGBStrokeColor(contextRef, 0, 0, 0, 1);
CGContextSetLineWidth(contextRef, 5.0);
CGContextBeginPath(contextRef);
CGContextMoveToPoint(contextRef, 0, 0);
CGContextAddLineToPoint(contextRef, 320, 480);
CGContextStrokePath(contextRef);
}
-(void)drawLine:(CGPoint)from to:(CGPoint) to {
// Drawing code
CGContextRef contextRef = UIGraphicsGetCurrentContext();
//CGContextSetRGBFillColor(contextRef, 0, 0, 255, 1);
CGContextSetRGBStrokeColor(contextRef, 0, 128, 0, 1);
CGContextSetLineWidth(contextRef, 5.0);
CGContextBeginPath(contextRef);
CGContextMoveToPoint(contextRef, 0, 0);
CGContextAddLineToPoint(contextRef, 320, 50);
CGContextStrokePath(contextRef);
}
