multiple methods named '-position' found

[Shingo Satou]

Hi Guys,

I wrote the following programs.

-(void)changeSelectedIndex:(NSInteger)theSelectedIndex
{
	selectedIndex=theSelectedIndex;
	
	if (selectedIndex == [names count]) selectedIndex=[names count]-1;
	if (selectedIndex < 0) selectedIndex=0;

	selectionLayer.position = [[[menusLayer sublayers]
		objectAtIndex:selectedIndex] position];
};

When I Bild it, the following errors are output.

/Users/user/Desktop/CoreAnimationMenu/MenuView.m:160: warning:

/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSScriptObjectSpecifiers.h:191:
