Question

当我启动我的应用程序并从mainViewController转到flipSideViewController时，flipSideViewController中的图像视图将设置动画。我希望每次用户都能为它设置动画从mainViewController转换到flipSideViewController。

以下是一些代码：

[self animate];
//Not sure where to put this instance method. Would I put this in a certain method? I have no idea what I would write for it!

- (void)animate 
{
    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
    animation.toValue = [NSNumber numberWithFloat:((-10*M_2_PI)/180)];
    animation.duration = .3;
    animation.autoreverses = YES;
    animation.repeatCount = 4;
    animation.speed = 9;
    pwAnimation.removedOnCompletion = YES;
    [_ImageView.layer addAnimation:pwAnimation forKey:@"rotation"];
}

使用flipSideViewController的ViewDidAppear委托方法来调用你的-animate方法

如何在显示视图时开始动画？
