ios - 3D Touch 到一个类中的多个按钮

Question

我正在 iOS 中实现 3d touch peek an pop 功能。

这是我为一个按钮写的代码

- (UIViewController *)previewingContext:(id <UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{

    UIViewController *detailVC = [self.storyboard instantiateViewControllerWithIdentifier:@"detail"];


    detailVC.preferredContentSize = CGSizeMake(0.0, 500.0);

    previewingContext.sourceRect = self.btnDetail.frame;

    return detailVC;
}

这只是同一个 View 中的一个按钮，我还有 4 个其他按钮，我想在同一个类中应用 3d 触摸。我怎样才能做到这一点？？

您只需检查位置即可。例如:

- (UIViewController *)previewingContext:(id <UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{
    if(CGRectContainsPoint(self.btnDetail.frame,location)){
        UIViewController *detailVC = [self.storyboard instantiateViewControllerWithIdentifier:@"detail"];


        detailVC.preferredContentSize = CGSizeMake(0.0, 500.0);

        previewingContext.sourceRect = self.btnDetail.frame;

        return detailVC;
    }
    if(CGRectContainsPoint(self.otherBtn.frame,location)){
        UIViewController *otherVC = [self.storyboard instantiateViewControllerWithIdentifier:@"other"];


        otherVC.preferredContentSize = CGSizeMake(0.0, 500.0);

        previewingContext.sourceRect = self.otherBtn.frame;

        return otherVC;
    }
    …
}
