Creating image which sweeps across the screen - ios

Question

I'm trying to create a banner that sweeps across the current scene. I want to create a banner which sweeps down the screen to show the current round. My attempt at it is creating a UIImageView and add it to the current view. However, i assume its calling the didMoveToView Function and resetting everything in that scene, which is something i dont want it to do. Here is my attempt:
-(void)createBanner{
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Banner"]];
[imageView setFrame:CGRectMake(0,0, imageView.frame.size.width, imageView.frame.size.height)];
[imageView setClipsToBounds:YES];
[self.view addSubview:imageView];
CABasicAnimation *sweep = [CABasicAnimation animationWithKeyPath:#"position"];
sweep.fromValue = [NSValue valueWithCGPoint:CGPointZero];
sweep.toValue = [NSValue valueWithCGPoint:CGPointMake(0.0, self.frame.size.height)];
sweep.duration = 10;
sweep.additive = YES;
[imageView.layer addAnimation:sweep forKey:#"sweep"];
}
EDIT: i am using sprite kit in order to create the game.

As hamobi said, it's best to use an 'SKSpriteNode' in Sprite Kit and not UIKit. Assuming your'e adding to an 'SKScene', your code above translated to Sprite Kit is:
-(void)createBanner{
SKSpriteNode* spriteNode = [SKSpriteNode spriteNodeWithImageNamed:#"Banner"]
//It's good practice not to resize the sprite in code as it should already be the right size but...
spriteNode.size = CGSizeMake(self.size.width, self.size.height)
//Set its center off to the left of the screen for horizontal sweep, or you can do vertical and set it off the top of the screen...
spriteNode.postion = CGPointMake(-spriteNode.size.width/2, self.size.height/2)
self.addChild(spriteNode)
//Then to sweep from left to right...
SKAction* sweep = [SKAction moveTo:CGPointMake(spriteNode.size.width/2, self.size.height/2) duration:10]
spriteNode.runAction(sweep)
}
I think that covers most of it.
