    copied!<p>I'm just getting into iOS development. I'm tinkering with core graphics, and I'm trying to figure out how to both limit the size of a drawing, and place it at specific coordinates on the screen. Here is my HomeViewController.m loadView AND addCircle method, and my Artist.m drawRect method:</p> <p>HomeViewController.m -> loadView</p> <pre><code>- (void)loadView { NSLog(@"HomeViewController.m : loadView"); self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; UILabel *lbl; lbl = [[UILabel alloc] initWithFrame:CGRectMake(65, 50, 220, 70)]; lbl.text = @"Home Screen"; lbl.font = [UIFont boldSystemFontOfSize:30]; [self.view addSubview:lbl]; [lbl release]; UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoDark ]; infoButton.frame = CGRectMake(10, 10, 300, 300); [self.view addSubview:infoButton]; [infoButton addTarget:self action:@selector(loadInfo) forControlEvents:UIControlEventTouchUpInside]; [infoButton release]; [self addCircle]; // self.view = [[[Artist alloc] init] autorelease]; } </code></pre> <p>HomeViewController.m -> addCircle</p> <pre><code>- (void)addCircle { Artist *artist = [[[Artist alloc] init] autorelease]; [self.view addSubview:artist]; // [artist drawRect:CGRectMake(100, 100, 100, 100)]; } </code></pre> <p>Artist.m -> drawRect</p> <pre><code>- (void)drawRect:(CGRect)rect { NSLog(@"Artist.m : drawRect"); // Drawing code CGContextRef context = UIGraphicsGetCurrentContext(); CGColorRef red = [[UIColor redColor] CGColor]; CGContextFillRect(context, CGRectMake(130,200,120,120)); CGContextSetFillColorWithColor(context,red); CGContextFillEllipseInRect(context, CGRectMake(130, 200, 120, 120)); } </code></pre> <p>Essentially, I'm trying to avoid having the drawing take up the whole screen, but rather be limited to the size that I make it and sit on top of the other views.</p>
