Question

我想要缩小＆＃34;预览＆＃34;另一个ViewController中的另一个ViewController。这可能吗？不需要任何交互，因此它基本上可以是截图，但缩小。我可以通过手动截取屏幕并将其保存为图像来解决，但ViewController包含大量本地化并且不断更新，因此如果可以以编程方式完成此操作。

这可能吗？

编辑：子视图存储在故事板中

编辑：这就是我解决它的方式：

//Load the viewcontroller and view
previewViewController = [self.storyboard instantiateViewControllerWithIdentifier:[PLACEHOLDER_VIEWCONTROLLER_NAMES objectAtIndex:self.identifier]];
[self addChildViewController:previewViewController];
[self.placeholderView.superview addSubview:previewViewController.view];
previewViewController.view.transform = CGAffineTransformMakeScale(scale*2, scale*2);
CGPoint center = self.placeholderView.center;
center.y += 25;
previewViewController.view.center = center;

Answer 1

使用viewController.view，然后将其缩小为：

viewController.view.transform = CGAffineTransformMakeScale(0.5, 0.5);

Answer 2

Add your another view controller view as subview to first viewcontroller


[UIView animateWithDuration:2.0f animations:^{

    InnerView.userInteractionEnabled = NO;

    //Always starts from original scale
    InnerView.transform = CGAffineTransformMakeScale(0.5, 0.5);

    //Incremental scale
    //InnerView.transform = CGAffineTransformScale(InnerView.transform, 0.5, 0.5);


} completion:^(BOOL finished) {


    NSLog(@"in Half size");

}];




[UIView animateWithDuration:2.0f animations:^{

    InnerView.transform = CGAffineTransformIdentity;


} completion:^(BOOL finished) {

    InnerView.userInteractionEnabled = YES;

    NSLog(@"Normal size");


}];
