iOS Animation动画 让图片不停的旋转360度

第一种 让图片不停的旋转360度

{

    double angle;

    UIImageView *p_w_picpathView;

}

 p_w_picpathView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 100, 30, 5)];

    p_w_picpathView.p_w_picpath = [UIImage p_w_picpathNamed:@"1111.jpg"];

    [self.view addSubview:p_w_picpathView];

- (void)loopBasicAnimation

{

    //动画

    CABasicAnimation* rotationAnimation;

    rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];

    rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 ];

    rotationAnimation.duration = 0.8;

    rotationAnimation.cumulative = YES;

    rotationAnimation.repeatCount = ULLONG_MAX;

    [p_w_picpathView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];

}

第二种

- (void)stopLoppAnimation1{

    CGAffineTransform endAngle = CGAffineTransformMakeRotation(angle * (M_PI / 180.0f));

//时间

    [UIView animateWithDuration:0.01 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{

        p_w_picpathView.transform = endAngle;

    } completion:^(BOOL finished) {

        angle = angle+10; //旋转速度的快慢

        [self stopLoppAnimation1];

    }];

}
