iOS Some Size issue I think.

[IDMah]

Hi again..

I'm trying to animate with a UIImageView.
using this.

-(void)animateNewStampImage:(UIImage *)myStamp ToHere:(CGRect)finalRect
{
	
	CGRect bounds = [self bounds];
	
	CGPoint topLeftCorner;
	CGPoint centre;
	topLeftCorner.x = bounds.origin.x + bounds.size.width ; // in percentage of screen size //
	topLeftCorner.y = bounds.origin.y + bounds.size.height; // in percentage of the screen size // 
	
	centre.x = bounds.origin.x + bounds.size.width / 2; // in percentage of screen size //
	centre.y = bounds.origin.y + bounds.size.height/ 2; // in percentage of the screen size // 
	/*
	UIImage* animStampImage = UIGraphicsGetImageFromCurrentImageContext();
	UIGraphicsEndImageContext();
	*/
	UIImageView *myNewStamp = [[[UIImageView alloc]initWithImage:[myStamp stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]]retain]; 
							
	myNewStamp.bounds = CGRectMake(0,0,bounds.size.width,bounds.size.height);
	//[myNewStamp setFrame:CGRectMake(0,0,bounds.size.width,bounds.size.height)];
	//[myNewStamp setBounds:CGRectMake(0,0,bounds.size.width,bounds.size.height)];
	
	//NSLog(@"animating Stamp");
	//UIImageView * myNewStamp = [[UIImageView alloc] initWithImage:myStamp];
	//[myNewStamp setFrame:CGRectMake(0,0,bounds.size.width,bounds.size.height)];
	
	CABasicAnimation *opacityAnimm = [CABasicAnimation animationWithKeyPath:@"opacity"];
	CABasicAnimation *scaleAnimm = [CABasicAnimation animationWithKeyPath:@"transform"];
	CABasicAnimation *positionAimm = [CABasicAnimation animationWithKeyPath:@"position"];
	
	scaleAnimm.fromValue = [NSValue valueWithCATransform3D:CATransform3DMakeScale(1,1,1.0)];
	scaleAnimm.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeScale(.1,.1,1.0)];		
	scaleAnimm.removedOnCompletion = YES;
	
	CGPoint positionStampNew = finalRect.origin;
	//positionAimm.fromValue =[NSValue valueWithCATransform3D:CATransform3DMakeTranslation(positionStampNew.x,positionStampNew.y,0)];
	//positionAimm.fromValue =[NSValue valueWithCATransform3D:CATransform3DMakeTranslation(positionStampNew.x,positionStampNew.y,0)];
	positionAimm.fromValue =[NSValue valueWithCGPoint:positionStampNew];
	//NSLog(@" x: %f y: %f",finalRect.origin.x,finalRect.origin.y);
	
	CGPoint sumRandomPosition = CGPointMake(arc4random()%20+finalRect.origin.x,arc4random()%20+finalRect.origin.y);
	positionAimm.toValue = [NSValue valueWithCGPoint:sumRandomPosition];
	//positionAimm.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeTranslation(sumRandomPosition.x,sumRandomPosition.y,0)];
	positionAimm.removedOnCompletion = YES;
	NSLog(@" x: %f y: %f to X:%f Y:%f",positionStampNew.x,positionStampNew.y,sumRandomPosition.x,sumRandomPosition.y);
	
	opacityAnimm.toValue = [NSNumber numberWithFloat:0.6];
	opacityAnimm.fromValue = [NSNumber numberWithFloat:0.1];
	opacityAnimm.removedOnCompletion = YES;
	
	CAAnimationGroup *animGroupp = [CAAnimationGroup animation];
	
	animGroupp.animations = [NSArray arrayWithObjects:opacityAnimm,scaleAnimm,positionAimm,nil];
	animGroupp.delegate = self;
	animGroupp.duration = 1.4;
	
	//[UIView setAnimationDidStopSelector:@selector(stopButton)];	 
	// [myNewStamp layer] //
	//
	
	[[myNewStamp layer] addAnimation:animGroupp forKey:@"newStamAnim"];
	
	[self addSubview:myNewStamp];
	[myNewStamp release];
	
}

called from this inside:

- (void)drawRect:(CGRect)rect {
// stampPost is a CGPoint read from an array of objects 
// stampSize is a CGSize read from an array of objects  --- both are correct when NSLogged - printed 

if (newStampMarker){
CGRect newStampRec = CGRectMake(stampPost.x,stampPost.y, stampSize.width, stampSize.height);
uiimage = [UIImage imageNamed:@"SmileyStampYellow.png"];
[self animateNewStampImage:uiimage ToHere:newStampRec];
}
// also using this to draw non new stamps works fine // 
[uiimage drawInRect:CGRectMake(stampPost.x,stampPost.y, stampSize.width, stampSize.height)];

// and I add it to the View with this. //
        UIImage* blendedImage = UIGraphicsGetImageFromCurrentImageContext();
	UIGraphicsEndImageContext();
	
	UIImageView *stampOverlay = [[UIImageView alloc] initWithImage:blendedImage]; 
	
	[blendedImage release];
	//[uiimage release];
	
	[stampOverlay setFrame:CGRectMake(0,0,bounds.size.width,bounds.size.height)];
	[stampOverlay setAlpha:STAMPBASE];
	
	[self addSubview:stampOverlay];
	


}

So my sticker appear ok but the animating ones are too big and not in the right spot, how do I scale them to match the view / drawInRect image.

P.S sorry for the messy code..
thank

works better on Layer.

Ok think this is a Nube mistake.
but seem to work better on a Layer.

added this..

CALayer *newStampLayer = [[CALayer alloc] init];
	[newStampLayer setBounds:bounds];
	
	//newStampLayer  // 	
	CGImageRef refStamp = [myStamp CGImage];
	
	[newStampLayer setContents:(id) refStamp];

	[[self layer] addSublayer:newStampLayer];
	[newStampLayer release];
	// .... and later locked the sticker to final position //
        //
        animGroupp.removedOnCompletion = NO;// <----- this is so counter intuitive !!! //
	animGroupp.fillMode = kCAFillModeForwards;
        [newStampLayer  addAnimation:animGroupp forKey:@"newStamAnim"];

Still looking for a way to relate one for one positioning on a scaled View

fudged to work.

I kept picking scales to make the Sticker fit. but there has to be a better way..

Help !!!!

also tried to add rotation.. with ..

// I wasn't using the right animationWithKeyPath:
CABasicAnimation *rotateAnimm = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
// this is the right one for what I wanted	
CGFloat rotRand = (arc4random()%42)*(M_PI/180); //  radians // 
	
rotateAnimm.fromValue = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(rotRand,0,0,1)]; // tried  0,0,1 and 1,0,0 nothing..  
	
// added to CAAnimationGroup of Course.. //

nothing spins..

Ok got it.. see above .. stupidity...

Animate in Context.

Not sure if I'm barking up the wrong tree but is there a way to
Animate in Context? and would that solve my sizing problems??

but can't seem to find anything in setting it in the layer or animation
level.

thanks
