如何在目标C中添加QLPreviewController作为Subview

问题描述

是否可以将QLPreviewController添加到UIView作为子视图。

Is it possible to add QLPreviewController to UIView as sub view.

我试过这样

[self.view addSubview:previewViewController.view] 

我也叫过 reloadData

[previewViewController reloadData];

我查看此网址。但是我不明白什么是 self.pdfPreviewView

I check with this URL Adding QLPreviewController as subview doesn't load PDF . But I did not understand what is self.pdfPreviewView

请指导我如何将QLPreviewController添加为子视图。 。

Please guide me how I can add QLPreviewController as sub view..

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;
