i have app color wheel , i'm trying pick random color within color wheel. however, i'm having problems verifying random point falls within color wheel. here's code is: cgpoint randompoint = cgpointmake(arc4random() % (int)colorwheel.bounds.size.width, arc4random() % (int)colorwheel.bounds.size.height); uicolor *randomcolor = [self colorofpoint:randompoint]; cgpoint pointinview = [colorwheel convertpoint:randompoint fromview:colorwheel.window]; if (cgrectcontainspoint(colorwheel.bounds, pointinview)) { nslog(@"%@", randomcolor); } else { nslog(@"out of bounds"); } a couple of other methods of verifying point i've tried no luck: if (cgrectcontainspoint(colorwheel.frame, randompoint)) { nslog(@"%@", randomcolor); } if ([colorwheel pointinside:[self.view convertpoint:randompoint toview: colorwheel] withevent: nil]) { nslog(@"%@", randomcolor); } sometimes it'll output "out of bounds", , it...
