Core Animation Programming Summary 2

Animation

The animation occurs automatically in a separate thread, without further interaction with your application.

Animation Classes and Timing

- CABasicAnimation

- CAKeyframeAnimation

- CATransition

- CAAnimationGroup

Implicit Animation

Implicitly animating multiple properties of multiple layers

theLayer.opacity = 0.0;
theLayer.zPosition = -100;

Explicit Animation

ex 1 

CABasicAnimation *theAnimation;
theAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"];
theAnimation.duration = 3.0;
theAnimation.repeatCount = 2;
theAnimation.autoreverse = YES;
theAnimation.fromValue = [NSNumber numberWithFloat:1.0];
theAnimation.toValue = [NSNumber numberWithFloat:0.0];
[theLayer addAnimation:theAnimation forKey:@"animateOpacity"];

ex 2

CIFileter *filter = [CIFilter filterWithName:@"CIBloom"];
[filter setDefaults];
[filter setValue:[NSNumber numberWithFloat:5.0] forKey:@"inputRadius"];
[filter setName:@"pulseFilter"];
[selectionLayer setFilters:[NSArray arrayWithObject:filter]];
CABasicAnimation* pulseAnimation = [CABasicAnimation animation];
pulseAnimation.keyPath = @"filters.pulseFilter.inputIntensity";
pulseAnimation.fromValue = [NSNumber numberWithFloat:0.0];
pulseAnimation.toValue = [NSNumber numberWithFloat:1.5];
pulseAnimation.duration = 1.0;
pulseAnimation.repeatCount = HUGE_VALF;
pulseAnimation.autoreverses = YES;
pulseAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
[selectionLayer addAnimation:pulseAnimation forKey:@"pulseAnimation"];

Starting and Stopping Explicit Animations

addAnimation:forKey:

removeAnimationForKey:

removeAllAnimations

Layer Actions

A Layer is responsible for mapping action identifiers to the appropriate action objects.

typically, action objects are an instance of a CAAnimation subclass, which implements the CAAction protocol.

When an instance of CAAnimation receives the runActionForKey:object:arguments: message it responds by adding itself to the layer's animations

The Role of Action Objects

Adopting the CAAction Protocol

?

- (void) runActionForKey:(NSString*)key
object:(id)anObject
arguments:(NSDictionary*)dict
{
[(CALayer*)anObject addAnimation:self forKey:key];
}

Overriding an Implied Animation

- (id<CAAction>)actionForLayer:(CALayer*)theLayer
forKey:(NSString*)theKey
{
CATransition *theAnimation = nil;
if ([theKey isEqualToString:@"contents"])
{
theAnimation = [[CATransition alloc] init];
theAnimation.duration = 1.0;
theAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
theAnimation.type = kCATransitionPush;
theAnimation.subtype = kCATransitionFromRight;
}
return theAnimation;
}

Implied animation for the sublayers property

NSMutableDictionary *customActions = [NSMutableDictionary dictionaryWithDictionary:[theLayer actions]];
//diable the animation for the sublayers property
[customActions setObject:[NSNull null] forKey:@"sublayers"];
theLayer.actions = customActions;

Transactions

Implicit transactions

theLayer.opacity = 0.0;
theLayer.zPosition = -200;
theLayer.position = CGPointMake(0.0, 0.0);

Explicit transactions

Explicit transactions are particularly useful when setting the properties of many layers at the same time (for example, while laying out multiple layers)

Temporarily disabling a layer's actions

[CATransaction begin];
[CATransaction setValue:(id)kCFBooleanTrue
forKey:kCATransactionDisableActions];
[aLayer removeFromSuperlayer];
[CATranscation commit];

Overriding the animation duration

[CATransaction begin];
[CATransaction setValue:[NSNumber numberWithFloat:10.0f]
forKey:kCATransactionAnimationDuration];
theLayer.zPosition = 200.0;
theLayer.opacity = 0.0;
[CATransaction commit];

Nesting explicit transactions

[CATransaction begin]; //outer transaction
//change the animation duration to 2 secs
[CATransaction setValue:[NSNumber numberWithFloat:2.0f]
forKey:kCATransactionAnimationDuration];
theLayer.position = CGPointMake(0.0, 0.0);
[CATransaction begin]; //inner transaction
[CATransaction setValue:[NSNumber numberWithFloat:5.0f]
forKey:kCATransactionAnimationDuration];
theLayer.zPosition = 200.0;
theLayer.opacity = 0.0;
[CATransaction commit]; //inner transaction
[CATransaction commit]; //outer transaction

Laying Out Core Animation Layers

Contraints Layout Manager

Default Value Support

+(id)defaultValueForKey:(NSString*) key
{
if ( [key isEqualToString:@"masksToBounds"] )
return [NSNumber numberWithBool:YES];
return [super defaultValueForKey:key];
}

myLayer.transform.rotation.x = 0; // this is wrong
[myLayer setValue:[NSNumber numberWithInt:0] forKeyPath:@"transform.rotation.x"];
//this is right.

Core Animation Programming Guide Summary

Core animation classes

- Layer classes that provide content for display

- Animation and timing classes

- Layout and constraint classes

- A transaction class that groups multiple layer changes into an atomic update

Layer classes

CALayer is the parent class for all types of Core animation layers.

CALayer diverges from the application kit and cocoa touch view classes in that it's not necessary to subclass CALayer in order to display content.

Animation and Timing Classes

CAAnimation adopts CAMediaTiming protocol which provides the simple duration,speed and repeat count for an animation.

and adopts CAAction protocol.

- CATransition

- CAAnimationGroup

- CAPropertyAnimation

- CABasicAnimation 

- CAKeyframeAnimation

Layout Manager Classes

- CAContraint

Transaction Management Classes

Core Animation Rendering Architecture

NSView,UIView are objects in the MVC pattern.

Core Animation Layers are model objects.

the actual display is not the layer's responsibility.

a presentation tree and a render tree.

layer-tree -> Presentation-tree -> Render-tree (Private)

Layer-tree Hierarchy

Displaying Layers in Views

[theView setLayer: theRootLayer];

[theView setWantsLayer:YES];

Adding,Removing Layers from a Hierarchy

while inserting,removing,replacing layers cause kCAOnOrderIn, kCAOnOrderOut, kCATransition triggered.

Repositioning and Resizing Layers

If a layer's needsDisplayOnBoundsChange property is YES, the layer's content is recached when the layer's bounds changes. this value is no by default.

Autoresizing Layers

CAAutoresizingMask

Clipping Sublayers

masksToBounds determines if sublayers are clipped to the parent.

Providing Layer Content

When using Cocoa views you must subclass NSVIew or UIView and implement drawRect: in order to display anything. However CALayer instances can often be used directly, without requiring subclassing. Because CALayer is a key-value coding compliant container class, that is you can store arbitrary values in any instance, subclassing can often be avoided entirely.

Providing CALayer Content

- Explicitly set the contents property of a layer instance using a CGImageRef that contains the content image.

- Specify a delegate that provides, or draws, the content.

- Subclass CALayer and override one of the display methods.

Setting the Contents Property

CALayer *theLayer;
theLayer = [CALayer layer];
theLayer.position = CGPointMake(50,50);
theLayer.bounds = CGRectMake(0,0,100,100);
theLayer.contents = theImage; //CGImageRef

Using a Delegate to Provide Content

displayLayer: or drawLayer:inContext: are called by sending it a setNeedsDisplay or setNeedsDisplayInRect: or needsDisplayOnBoundsChange = YES.

Subclassing is not required to store the state value, coz the CALayer instance acts as a key-value coding container.

- (void)displayLayer:(CALayer*)theLayer
{
if ([[theLayer valueForKey:@"state"] boolValue])
{
theLayer.contents = [someHelperObject loadStateYesImage];
}
else {
theLayer.contents = [someHelperObject loadStateNoImage];
}
}

if you must the layer's content rather than loading it from an image, use drawLayer:inContext:

- (void)drawLayer:(CALayer*)theLayer inContext:(CGContextRef)theContext
{
CGMutablePathRef thePath = CGPathCreateMutable();
CGPathMoveToPoint( thePath,NULL,15.0f,15.f);
CGPathAddCurveToPoint( thePath, NULL, 15.f,250.f,295.f,250.f,295.f,15.f );
CGContextBeginPath(theContext);
CGContextAddPath(theContext, thePath);
CGContextSetLineWidth( theContext, [[theLayer valueForKey:@"lineWidth"] floatValue]);
CGContextStokePath(theContext);
CFRelease(thePath);
}

Providing CALayer Content by Subclassing

using property rather than depending on the key-value coding container.

- (void)display{ if(self.state) { self.contents = [someHelperObject loadStateYesImage]; } else { self.contents = [someHelperObject loadStateNoImage]; }}
- (void)drawInContext:(CGContextRef)theContext{ CGMutablePathRef thePath = CGPathCreateMutable(); CGPathMoveToPoint(thePath,NULL,15.f,15.f); CGPathAddCurveToPoint(thePath,NULL,15.f,250.f,295.f,250.f,295.f,15.f); CGContextBeginPath(theContext); CGContextAddPath(theContext, thePath); CGContextSetLineWidth(theContext,self.lineWidth); CGContextSetStrokeColorWithColor(theContext, self.lineColor); CGContextStrokePath(theContext); CFRelease(thePath);}

Positioning Content Within a Layer

contentsGravity property allows you to position and scale the layer's contents image within the layer bounds. by default, the content image fills the layer's bounds entirely, ignoring the natural aspect ratio of the image.

if we added more codes in setter/getter methods, we must override them by ourself in inherited class.

@interface ParentClass:NSObject

@property (nonatomic) int type;

- (void)updateData;

@implentation ParentClass

@synthesize type = _type;

- (void) setType:(int) pType {

    _type = pType;

}

- (void) updateData

{

    self.type ++;

    NSLog("%d",self.type);

}

- (void) doSomething

{

    NSLog(@"ParentClass:doSomething called!!");

}

@end

@interface ChildClass: ParentClass

@end

@implementation ChildClass

@synthesize type = _type;

- (void) updateData {

    [super updateData];    // doSomething is not called!!

}

- (void) doSomething

{

   NSLog(@"ChildClass:doSomething called!!");

}

@end

changed this.

@implementation ChildClass

@synthesize type = _type;

- (void) setType:(int) pType {
    _type = pType;

    

    [self doSomething];
}

- (void) updateData {
    [super updateData];    // doSomething is called
}

- (void) doSomething
{
   NSLog(@"ChildClass:doSomething called!!");
}

@end

coz, @synthesize make default setter/getter methods by itself. so these methods are different from them that you implemented in super class.

Objective-C setter method

@property(nonatomic,retain) NSObject * exVal;

@synthesize exVal;

- (void)setExVal:(NSObject*) val {

   [exVal release]; 
   exVal = [val retain];
}

this is wrong. coz if val is equal to exVal, both exVal and val are released. and then nil retain.

- (void)setExVal:(NSObject*) val {

    [val retain];

    [exVal release];

    exVal = val;

}

this is right.

Big Endian, Little Endian

Big Endian, Little Endian

I sometimes got confused about these.
What is big or little?
and
What is Endian?

I will try to figure these out at this time.

------------------------
big, little : the value of byte
endian : the end of memory that occupied by the value in row.


so, Big endian means that Big value of byte is located in the end of memory.
