Using Cabasicanimation to Rotate a Uiimageview More Than Once

Using CABasicAnimation to rotate a UIImageView more than once

pass incremental value of angle see my code

static int imgAngle=0;
- (void)doAnimation
{
  CABasicAnimation *animation = [CABasicAnimation   animationWithKeyPath:@"transform.rotation.z"];
   animation.duration = 5;
  animation.additive = YES;
  animation.removedOnCompletion = NO;
  animation.fillMode = kCAFillModeForwards;
  animation.fromValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(imgAngle)];
  animation.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(imgAngle+90)];
 [self.imgView.layer addAnimation:animation forKey:@"90rotation"];

  imgAngle+=90;
  if (imgAngle>360) {
      imgAngle = 0;
  }
}

Above code is just for idea. Its not tested

CABasicAnimation of object around itself (360 degrees)

If you want to change the anchor point of stick use:

stick.layer.anchorPoint = CGPointMake(1.0,1.0);

The rotation code I use:

CABasicAnimation *rotateAnim = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
    rotateAnim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
    rotateAnim.fromValue = [NSNumber numberWithFloat:0];
    rotateAnim.toValue = [NSNumber numberWithFloat:(360 * M_PI / 180.0f)];
    rotateAnim.repeatCount = HUGE_VALF;
    rotateAnim.duration = 2.5;
    rotateAnim.removedOnCompletion = NO;

    [view.layer addAnimation:rotateAnim forKey:@"rotationAnimation"];

Rotating UIImageView more than 180 degrees using animations on iOS

//Add This in header prefix

 #define MAXFLOAT    0x1.fffffep+127f

// add For rotation

 [UIView animateWithDuration:1.5 animations:^{
      CABasicAnimation *fullRotation;
    fullRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
    fullRotation.fromValue = [NSNumber numberWithFloat:0];
    fullRotation.toValue = [NSNumber numberWithFloat:(2*M_PI))];
    fullRotation.duration =1.0f;
    fullRotation.repeatCount = MAXFLOAT;
    // add animation in your view
    [yourView.layer addAnimation:fullRotation forKey:@"360"];
    [self performSelector:@selector(stopRotate:) withObject:yourView afterDelay:1.0];
}];

And Add this code to stop rotation From view

-(void)stopRotate :(UIView *)yourView
{
  [yourView.layer removeAnimationForKey:@"360"];
}

Rotate and translate UIImageView off and on screen

try This, it will Work for you

  CABasicAnimation* rotationAnimation;
    rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
    rotationAnimation.toValue = [NSNumber numberWithFloat: -M_PI * 2.0 /* full rotation*/ * 2 * 1 ];
    rotationAnimation.duration = 1;
    rotationAnimation.cumulative = YES;
    rotationAnimation.repeatCount = 1.0; 
    rotationAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    rotationAnimation.delegate = self;

    CABasicAnimation* translationAnimation;
    translationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.translation.x"];
    translationAnimation.toValue = [NSNumber numberWithFloat:-700];
    translationAnimation.duration = 1;
    translationAnimation.cumulative = YES;
    translationAnimation.repeatCount = 1.0; 
    translationAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    translationAnimation.removedOnCompletion = NO;
    translationAnimation.fillMode = kCAFillModeForwards;

    CAAnimationGroup *group = [CAAnimationGroup animation];
    group.animations = [NSArray arrayWithObjects:rotationAnimation,translationAnimation, nil];
    group.delegate = self;
    group.removedOnCompletion = NO;
    group.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

    [[self.imageView.layer addAnimation:group forKey:@"randt"];

Rotate imageView random

You can use CABasicAnimation to animate z rotation. You can do as follow:

let rotateView = CABasicAnimation()
let randonAngle = arc4random_uniform(361) + 360
rotateView.fromValue = 0
rotateView.toValue = Float(randonAngle) * Float(M_PI) / 180.0
rotateView.duration = 1
rotateView.repeatCount = 0
rotateView.removedOnCompletion = false
rotateView.fillMode = kCAFillModeForwards
rotateView.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseOut)
view.layer.addAnimation(rotateView, forKey: "transform.rotation.z")
