UIAnimation

An abstract superclass used to animate properties of a UIView. It is supported by a collection concrete subclasses provided for the alpha, frame, scroll position, affine transformation (including a special subclass for rotation), and zooming.

// Constants

typedef enum {

    kUIAnimationCurveEaseInEaseOut,

    kUIAnimationCurveEaseIn,

    kUIAnimationCurveEaseOut,

    kUIAnimationCurveLinear

} UIAnimationCurve;



@interface UIAnimation : NSObject {}

// Creating animations

// Properties

- (float)progressForFraction:(float)fraction;


// Implemented by subclasses

- (void)setProgress:(float)progress;


// Controlling animations

- (void)stopAnimation;


@end



// Provided UIAnimation subclasses


// alpha

@interface UIAlphaAnimation : UIAnimation {}


- (void)setStartAlpha:(float)alpha;

- (void)setEndAlpha:(float)alpha;


- (float)alphaForFraction:(float)fraction;


@end


// frame

@interface UIFrameAnimation : UIAnimation {}


- (void)setStartFrame:(CGRect)frame;

- (void)setEndFrame:(CGRect)frame;


- (CGRect)endFrame;


@end


// rotation

@interface UIRotationAnimation : UIAnimation {}


- (void)setStartRotationAngle:(float)angle;

- (void)setEndRotationAngle:(float)angle;


@end


// scroll

@interface UIScrollAnimation : UIAnimation {}


- (void)setStartPoint:(CGPoint)startPoint;

@end


// transform

@interface UITransformAnimation : UIAnimation {}


- (void)setStartTransform:(CGAffineTransform)transform;

- (void)setEndTransform:(CGAffineTransform)transform;


- (CGAffineTransform)transformForFraction:(float)fraction;


@end


// zoom

@interface UIZoomAnimation : UIAnimation {}


+ (float)defaultDuration;


+ (id)zoomAnimationForTarget:(id)target endScale:(float)scale endScrollPoint:(CGPoint)point;

+ (id)zoomAnimationForTarget:(id)target focusRect:(CGRect)focusRect deviceBoundaryRect:(CGRect)deviceBoundaryRect scale:(float)scale;


- (void)setEndScale:(float)scale;

- (void)setStartScale:(float)scale;

- (void)setEndScrollPoint:(CGPoint)point;

- (void)setStartScrollPoint:(CGPoint)point;


@end



UIView (Animation) from UIAnimation.h

This category on UIView allows for automatically animating view properties, and also allows modifying global animation parameters inside an animation grouping. This is the preferred way to animate views.

@interface UIView (Animation)


+ (void)enableAnimation;

+ (void)disableAnimation;


+ (void)beginAnimations:(id)unknown;

+ (void)endAnimations;


+ (void)setAnimationAutoreverses:(BOOL)autoreverses;

+ (void)setAnimationCurve:(UIAnimationCurve)animationCurve;

+ (void)setAnimationDelay:(double)startDelay;

+ (void)setAnimationDelegate:(id)delegate;

+ (void)setAnimationDuration:(double)duration;

+ (void)setAnimationFrameInterval:(double)minimumTimeIntervalBetweenFrames;

+ (void)setAnimationFromCurrentState:(BOOL)shouldAnimateFromCurrentState;

+ (void)setAnimationPosition:(CGPoint)position;

+ (void)setAnimationStartTime:(double)startTime;

+ (void)setAnimationRepeatCount:(float)repeatCount;

+ (void)setAnimationRoundsToInteger:(BOOL)shouldRoundToInteger;

+ (void)setAnimationWillStartSelector:(SEL)willStartSelector;

+ (void)setAnimationDidStopSelector:(SEL)willEndSelector;


- (void)addAnimation:(UIAnimation *)animation forKey:(NSString *)key;


@end



UIAnimator from UIAnimation.h

UIAnimator provides a shared controller for starting and stopping global animations. The animation methods in UIView are preferred over UIAnimator.

@interface UIAnimator : NSObject {}


+ (id)sharedAnimator;


+ (void)disableAnimation;

+ (void)enableAnimation;


- (void)addAnimation:(UIAnimation *)animation withDuration:(double)duration start:(BOOL)start;

- (void)addAnimations:(NSArray *)animations withDuration:(double)duration start:(BOOL)start;

- (void)removeAnimationsForTarget:(id)target;

- (void)removeAnimationsForTarget:(id)target ofKind:(Class)classOfTarget;


- (void)startAnimation:(UIAnimation *)animation;

- (void)stopAnimation:(UIAnimation *)animation;


- (float)fractionForAnimation:(UIAnimation *)animation;


@end



UIResponder

UIResponder is an abstract superclass that provides the event handling and responder chain controller. See also NSResponder.

struct __GSEvent;

typedef struct __GSEvent GSEventRef;


@interface UIResponder : NSObject {}


// events

- (void)mouseDown:(GSEventRef)event;

- (void)mouseUp:(GSEventRef)event;

- (void)mouseDragged:(GSEventRef)event;

- (void)mouseEntered:(GSEventRef)event;

- (void)mouseExited:(GSEventRef)event;

- (void)mouseMoved:(GSEventRef)event;

- (void)scrollWheel:(GSEventRef)event;

- (void)keyDown:(GSEventRef)event;

- (void)keyUp:(GSEventRef)event;

- (void)gestureStarted:(GSEventRef)event;

- (void)gestureEnded:(GSEventRef)event;

- (void)gestureChanged:(GSEventRef)event;


// controlling the responder chain

- (id)nextResponder;

- (unsigned int)becomeFirstResponder;

- (BOOL)canBecomeFirstResponder;

- (BOOL)resignFirstResponder;

- (BOOL)canResignFirstResponder;

- (BOOL)isFirstResponder;

- (id)firstResponder;


@end



UIWindow

UIWindow handles events and mangages the device display for a UIView that is visible onscreen. See also NSWindow.

@interface UIWindow : UIView {}


// finding the key window

+ (UIWindow *)keyWindow;


// unknown

+ (CGRect)constrainFrameToScreen:(CGRect)rect;


// designated initializer

- (id)initWithContentRect:(CGRect)frame;


// the contentView should be set immediately after creating the window

- (UIView *)contentView;

- (void)setContentView:(UIView *)contextView;


// window properties

- (void)setFrame:(CGRect)fp8;

- (void)setTransform:(CGAffineTransform)fp8;


// handling interface events

- (BOOL)shouldRespondToStatusBarHeightChange;

- (void)handleStatusBarHeightChange;


// events and responders

- (void)sendEvent:(UIEvent *)event;

- (void)setBecomeKeyOnOrderFront:(BOOL)shouldBecomeKey;

- (void)orderFront:(id)sender;

- (void)orderOut:(id)sender;

- (void)makeKey:(id)sender;

- (id)firstResponder;

- (id)nextResponder;


// coordinate conversion

- (CGPoint)warpPoint:(CGPoint)point;

- (CGPoint)convertWindowToDevice:(CGPoint)point;

- (CGPoint)convertDeviceToWindow:(CGPoint)point;


// setting the backlight level

- (void)setLevel:(float)level;

- (float)level;


// unknown

- (void)setOutput:(int)output;

- (int)output;

- (void)synchronizeDrawingWithID:(int)fp8;

- (void *)createCoreSurfaceWithFrame:(CGRect)fp8;

- (void *)createCoreSurface;

- (id)representation;

- (void)writeSnapshotsToDir:(NSString *)directoryPath;

- (int)controlTint;
