objective-c – 如何将QLPreviewController添加为目标C中的子视图

可以将QLPreviewController添加到UIView作为子视图.

我试过这样

[self.view addSubview:previewViewController.view]

我也叫reloadData

[previewViewController reloadData];

我检查这个URL Adding QLPreviewController as subview doesn’t load PDF.但我不明白是什么是self.pdfPreviewView

请指导我如何添加QLPreviewController作为子视图..

解决方法

是可能的,请看下面的代码：

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,w,h);
[self.quickLookView addSubview:preview.view];    
[preview didMovetoParentViewController:self];
//save a reference to the preview controller in an ivar
self.previewController = preview;
