Question

我想让我的视图转换为从右向左滑动，而不是从左到右滑动。所以我找到了这段代码：

- (void) imgSlideInFromLeft : (UIView *) view
{
    CATransition *transition = [CATransition animation];
    transition.duration = 0.4;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype =kCATransitionFromLeft;
    transition.delegate = self;
    [view.layer addAnimation:transition forKey:nil];
}

然后我添加了QuartzCore的框架并导入了<QuartzCore/QuartzCore.h>，但我现在收到了这些错误：

您好像忘记将QuartzCore.framework添加到自己的应用中了？

使用CATransition时，链接器命令失败，退出代码为1
