AnimationsView_1 = [[UIImageView alloc] initWithFrame:CGRectMake(0, 64, imageView.width , imageView.width *(150.0/1788.0))];
AnimationsView_1.image=imageNamed(@"PointerIocon");
AnimationsView_1.centerX=self.width/2.0;
AnimationsView_1.centerY=imageView.centerY;
[self addSubview:AnimationsView_1];
CABasicAnimation* rotationAnimation;
rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 ];
rotationAnimation.duration = 5;
rotationAnimation.cumulative = YES;
rotationAnimation.repeatCount = 1000;
[AnimationsView_1.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];
其他方法：
-(void) startAnimation
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.01];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(endAnimation)];
imageView.transform = CGAffineTransformMakeRotation(angle * (M_PI / 180.0f));
[UIView commitAnimations];
}
-(void)endAnimation
{
angle += 10;
[self startAnimation];
}
当然你可以用block的方式写也是一样的。
- (void)startAnimation
{
CGAffineTransform endAngle = CGAffineTransformMakeRotation(imageviewAngle * (M_PI / 180.0f));
[UIView animateWithDuration:0.01 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
imageView.transform = endAngle;
} completion:^(BOOLfinished) {
angle += 10; [self startAnimation];
}];
}
PS：其中angle是double类型。
这下就可以360度旋转了。
