iOS Error (Expected':'before '~' token)

[rustywild]

I Have it:

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
} 
-(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
	CGPoint newTouch = [[touches anyObject]locationInView:[self~CCC superview]]; // Error Expected':'before '~' token

 
	CGPoint lastTouch = [[touches anyObject]previousLocationInView:[self~CCC superview]];
	
	float xDif = newTouch.x - lastTouch.x;
	float yDif = newTouch.y - lastTouch.y;
	
	CGAffineTransform translate = CGAffineTransformMakeTranslation(xDif,~CCC yDif); 
	[self setTransform: CGAffineTransformConcat([self transform],~CCC translate)];
																	

} 
-(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
} 
-(void) touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event {
	[self touchesEnded:touches withEvent:event]; 
}

@end

How i can repair?

thanx

What is 'self~CCC' ?

I'm not sure you can use the character '~' in a variable name. this should probably be 'self.CCC'?

~ is certainly not valid in a variable name: it's a C special character and no special character may appear in a variable name.

If change '~', for '.' it's worse. Give me 5 erros

What was the ~ for. Why did you type it? Until we know that we can't really advise.

I copied the code from a book, I use it to move a photo with multitouch

And this is the problem with copying stuff. Don't copy anything that you don't understand. And that means every character, line and statement.

Which book?

EDIT: Nevermind I see it. It seems to be a typesetting flaw in the eBook version of Rory Lewis' "IPHONE AND IPAD APPS FOR ABSOLUTE BEGINNERS" (who knows. maybe the hardcopy has the same issue). The screenshot of the code doesn't have ~CCC while the code block itself does. In other examples, code blocks include a stylized arrow to visually represent a carriage return, these ~CCCs seem to have been failed arrows.
