IOS animation effect

IOS animation effect

Most common Animation:
// Start the animation
[UIView beginAnimations: nil context: nil];
// Set the animation duration
[UIView setAnimationDuration: 2];
// Animation content
Frame. origin. x + = 150;
[Img setFrame: frame];
// Animation ends
[UIView commitAnimations];

Continuous Animation: displays a series of images one by one
NSArray * myImages = [NSArray arrayWithObjects:
[UIImage imageNamed: @myImage1.png],
[UIImage imageNamed: @myImage2.png],
[UIImage imageNamed: @myImage3.png],
[UIImage imageNamed: @myImage4.gif], nil];

UIImageView * myAnimatedView = [UIImageView alloc];
[MyAnimatedView initWithFrame: [self bounds];
MyAnimatedView. animationImages = myImages; // The animationImages attribute returns an array of animation images.
MyAnimatedView. animationDuration = 0.25; // time used to browse the entire image
MyAnimatedView. animationRepeatCount = 0; // 0 = number of times the loops forever animation is repeated
[MyAnimatedView startAnimating];
[Self addSubview: myAnimatedView];
[MyAnimatedView release];

CATransition Public API Animation:
CATransition * animation = [CATransition animation];
// Animation time
Animation. duration = 0.5f;
// Slow down first and then fast
Animation. timingFunction = UIViewAnimationCurveEaseInOut;
Animation. fillMode = kCAFillModeForwards;
// Animation. removedOnCompletion = NO;

// Various animation Effects
/*
KCATransitionFade;
KCATransitionMoveIn;
KCATransitionPush; z
KCATransitionReveal;
*/
/*
KCATransitionFromRight;
KCATransitionFromLeft;
KCATransitionFromTop;
KCATransitionFromBottom;
*/
// Various combinations
Animation. type = kCATransitionPush;
Animation. subtype = kCATransitionFromRight;

[Self. view. layer addAnimation: animation forKey: @ animation];

CATransition Private API Animation:
Animation. type can be set to the following effect:

The following is a blacklist:

SpewEffect: the new layout is released in the middle of the screen to overwrite the old layout.

-GenieEffect: the old version is sucked out at the lower left or lower right of the screen to display the new layout (Aladdin lamp God?) below ?).

-UnGenieEffect: the new layout is released in the lower left or lower right corner of the screen to overwrite the old layout.

-Twist: the layout is transferred horizontally like a tornado.

-Tubey: the layout is vertically attached with an elastic transfer.

-Swirl: the old version rotates at 360 degrees and fades out to display a new layout.

-CharminUltra: the old version fades out and displays the new layout.

-ZoomyIn: the new layout goes from small to front, and the old version disappears from front to front.

-ZoomyOut: zoomyOut appears outside the screen of the new layout, and the earlier version disappears.

-OglApplicationSuspend: the effect of pressing the home button.

UIView Animation:
[UIView beginAnimations: @ animationID context: nil];
[UIView setAnimationDuration: 0.5f];
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
[UIView setAnimationRepeatAutoreverses: NO];
// The following four effects
/*
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView: self. view cache: YES]; // oglFlip, fromLeft
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView: self. view cache: YES]; // oglFlip, fromRight
