Rotate image like wheel Animation and which stops at random position - ios

Question

I am creating a game in which the dice action is shows in a circle.When user clicks on the wheel it rotates and stop at random position.
I search and found some code which I tried to implement like:-
[UIView beginAnimations:#"RotationAnimation" context:nil];
CALayer *myLayer = diceCircle.layer;
CABasicAnimation *fullRotationAnimation;
fullRotationAnimation = [CABasicAnimation animationWithKeyPath:#"transform.rotation"];
fullRotationAnimation .fromValue = [NSNumber numberWithFloat:0];
// fullRotationAnimation.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
fullRotationAnimation.toValue = [NSNumber numberWithFloat:angle];
fullRotationAnimation.duration = 0.5; // speed for the rotation. Smaller number is faster
fullRotationAnimation.repeatCount = 1; // number of times to spin. 1 = once
[myLayer addAnimation:fullRotationAnimation forKey:#"360"];
[UIView commitAnimations];
angle is coming from:-
-(IBAction)diceButtonClicked:(id)sender
{
float angle=arc4random()%360;
NSLog(#"%f",angle);
float rad=radians(angle);
NSLog(#"%f",rad);
[self rotateDiceMethod:rad];
}
But the wheels stop at same position everytime and also does not always animate.Please suggest me some approach or sample code for implementing the required functionality.
Thanks in advance!

Answer 1

It's my old code for the same task:
CGFloat randValue= arc4random() % 10;
self.angleRotate = (randValue+30);
CABasicAnimation *spinAnimation = [CABasicAnimation animationWithKeyPath:#"transform.rotation.z"];
spinAnimation.fromValue = [NSNumber numberWithFloat:self.angle];
spinAnimation.toValue = [NSNumber numberWithFloat:self.angle+self.angleRotate];
spinAnimation.duration = 2.0f;
spinAnimation.cumulative = YES;
spinAnimation.additive = YES;
spinAnimation.removedOnCompletion = NO;
spinAnimation.delegate = self;
spinAnimation.timingFunction = [CAMediaTimingFunction
functionWithName:kCAMediaTimingFunctionEaseOut];
spinAnimation.fillMode = kCAFillModeForwards;
[self.arrow.layer addAnimation:spinAnimation forKey:#"spinAnimation"];
and when rotation is stopped
- (void)animationDidStop:(CAAnimation *)spinAnimation finished:(BOOL)flag{
self.angle += self.angleRotate;
while (self.angle >= M_PI*2.0) {
self.angle -= M_PI*2.0;
}
NSLog(#"angleRotate value is: %f", self.angleRotate);
NSLog(#"angle value is: %f", self.angle);
self.angleRotate = 0;
}
