fullRotation.fromValue = [NSNumber numberWithFloat:0];
fullRotation.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
fullRotation.duration = 99.0f;
fullRotation.removedOnCompletion = NO;
fullRotation.fillMode = kCAFillModeForwards;
fullRotation.repeatCount = MAXFLOAT;
[imageView.layer addAnimation:fullRotation forKey:@”360″];
