Software documentation for the NSAnimation class

NSAnimation : NSObject

Declared in:
AppKit/NSAnimation.h
Conforms to:
NSCopying
NSCoding
GSAnimation
Availability: MacOS-X 10.4.0

Objects of the NSAnimation class manage the timing and progress of animations in the user interface. The class also lets you link together multiple animations so that when one animation ends another one starts. It does not provide any drawing support for animation and does not directly deal with views, targets, or actions.

Instance Variables

Method summary

addProgressMark: 

- (void) addProgressMark: (NSAnimationProgress)progress;
Availability: MacOS-X 10.4.0

Adds the progress mark to the receiver.

animationBlockingMode 

- (NSAnimationBlockingMode) animationBlockingMode;
Availability: MacOS-X 10.4.0

Returns the blocking mode the receiver is next scheduled to run under.

animationCurve 

- (NSAnimationCurve) animationCurve;
Availability: MacOS-X 10.4.0

Returns the animation curve the receiver is running under.

clearStartAnimation 

- (void) clearStartAnimation;
Availability: MacOS-X 10.4.0

Clears linkage to another animation that causes the receiver to start.

clearStopAnimation 

- (void) clearStopAnimation;
Availability: MacOS-X 10.4.0

Clears linkage to another animation that causes the receiver to stop.

currentProgress 

- (NSAnimationProgress) currentProgress;
Availability: MacOS-X 10.4.0

Returns the current progress of the receiver.

currentValue 

- (float) currentValue;
Availability: MacOS-X 10.4.0

Returns the current value of the effect based on the current progress.

delegate 

- (id) delegate;
Availability: MacOS-X 10.4.0

Returns the delegate of the receiver.

duration 

- (NSTimeInterval) duration;
Availability: MacOS-X 10.4.0

Returns the duration of the animation, in seconds.

frameRate 

- (float) frameRate;
Availability: MacOS-X 10.4.0

Returns the frame rate of the animation.

initWithDuration: animationCurve: 

- (id) initWithDuration: (NSTimeInterval)duration animationCurve: (NSAnimationCurve)curve;
Availability: MacOS-X 10.4.0

Returns an NSAnimation object initialized with the specified duration and animation-curve values.

isAnimating 

- (BOOL) isAnimating;
Availability: MacOS-X 10.4.0

Returns a Boolean value that indicates whether the receiver is currently animating.

progressMarks 

- (NSArray*) progressMarks;
Availability: MacOS-X 10.4.0

Returns the receiver's progress marks.

removeProgressMark: 

- (void) removeProgressMark: (NSAnimationProgress)progress;
Availability: MacOS-X 10.4.0

Removes a progress mark from the receiver. A value that does not correspond to a progress mark is ignored.

runLoopModesForAnimating 

- (NSArray*) runLoopModesForAnimating;
Availability: MacOS-X 10.4.0

Overridden to return the run-loop modes that the receiver uses to run the animation timer in.

setAnimationBlockingMode:

setProgressMarks: 

- (void) setProgressMarks: (NSArray*)progress;
Availability: MacOS-X 10.4.0

Sets the receiver's progress marks to the values specified in the passed-in array. The new marks are t

startAnimation
