airplane = [[flyingObject alloc] init]; [airplane setPosition:[NSNumber numberWithFloat:0] Y:[NSNumber numberWithFloat:0]]; [airplane setSpeed:[NSNumber numberWithFloat:1]]; [airplane setHeadingByDegree:[NSNumber numberWithFloat:45]]; [airplane setMaxTurnSpeedByDegree:[NSNumber numberWithFloat:10]];

Keep in mind that [NSNumber numberWithFloat:1] creates an object that is autoreleased. Your flying object class should retain all of those NSNumber objects that you are sending to it.

For example:

- (void)setSpeed:(NSNumber*)newSpeed
{
if( newSpeed )
	[newSpeed retain];

if( speed )
	[speed release];

speed = newSpeed;

return;
}
