Question

I work on a project for iPhone iOS4 with Xcode.

From MainViewController I want to draw a little red square (fill only, not stroke) in MyView, a subclass of UIView. How can I pass position and RGB color of the square?

MyView.h (subclass of UIView)

 @interface {
 CGPoint position; // OK
 CGFloat[3] color; // ???
 }
 @property CGPoint position; // OK
 @property CGFloat color;    // ???

MyView.m

 @synthesize position; // OK
 @synthesize color;    // ???

MainViewController.h

 MyView *myRect;
 property IBOutlet MyView *myRect;

MainViewController.m

 @synthesize myRect;

 - (void) viewDidLoad
    myRect.position = CGPointMake (0, 0); // OK
    myRect.color = CGFloat [] = {255, 0, 0, 1}  // ??? 

I think I have no problems with the position of the square. But how can I pass the color of the square?

Thank you.

[myRect setBackgroundColor:[UIColor colorWithRed:color[0] green:color[1] blue:color[2] alpha:1.0]];
