推荐答案

是的，可以参考下面的代码：

Yes its possible, see the code below:

QLPreviewController* preview = [[QLPreviewController alloc] init];
preview.dataSource = self;
preview.delegate = self;
[self addChildViewController:preview];//*view controller containment
//set the frame from the parent view
CGFloat w= self.quickLookView.frame.size.width; 
CGFloat h= self.quickLookView.frame.size.height;
preview.view.frame = CGRectMake(0, 0,w, h);
[self.quickLookView addSubview:preview.view];    
[preview didMoveToParentViewController:self];
//save a reference to the preview controller in an ivar
self.previewController = preview;
