I have a UIView, I want to animate it using rotation. I also want to use autorun. I have already seen many common stackoverflow questions, but I have not found a suitable solution. So, start with my interface and animation code; I have a UIView with an image that needs to be rotated. And right now I have a button that activates the rotation. In the screenshot you can see the red cross, it should be the center of rotation (right now in the image, but I want to make the center of rotation outside the rotated UIView, I know that this can be archived using AnchorPoint).

This is my rotation animation code:
#define ROTATE_DURATION 3.0
- (IBAction)rotateArrow {
CGAffineTransform transform = self.hand.transform;
NSLog(@"layer possition before animation x: %f; y: %f",self.hand.layer.position.x,self.hand.layer.position.y);
[UIView animateWithDuration:ROTATE_DURATION/3 delay:0.0 options:UIViewAnimationOptionCurveLinear animations:^{
self.hand.transform = CGAffineTransformRotate(transform, 2*M_PI/3) ;
[self.hand layoutIfNeeded];
NSLog(@"layer possition after animation 1 x: %f; y: %f",self.hand.layer.position.x,self.hand.layer.position.y);
}
completion:^(BOOL finished) {
[UIView animateWithDuration:ROTATE_DURATION/3 delay:0.0 options:UIViewAnimationOptionCurveLinear animations:^{
self.hand.transform = CGAffineTransformRotate(transform, -2*M_PI/3) ;
[self.hand layoutIfNeeded];
NSLog(@"layer possition after animation 2 x: %f; y: %f",self.hand.layer.position.x,self.hand.layer.position.y);
}
completion:^(BOOL finished) {
[UIView animateWithDuration:ROTATE_DURATION/3 delay:0.0 options:UIViewAnimationOptionCurveLinear animations:^{
self.hand.transform = CGAffineTransformRotate(transform, 0) ;
[self.hand layoutIfNeeded];
NSLog(@"layer possition after animation 3 x: %f; y: %f",self.hand.layer.position.x,self.hand.layer.position.y);
}
completion:^(BOOL finished) {
}];
}];
}];
}
