iOS开发：读取pdf文件

方法一：使用QLPreviewController 

#pragma mark  浏览存在沙盒的文件

-(void)quickLook

{

    QLPreviewController *QLPreviewVc = [[QLPreviewController alloc] initWithNibName:nil bundle:nil];

    QLPreviewVc.dataSource = self;

    QLPreviewVc.delegate = self;

    

    [self presentViewController:QLPreviewVc animated:YES completion:nil];

}

 

#pragma mark QLPreviewControllerDelegate

- (void)previewControllerDidDismiss:(QLPreviewController *)controller

{

    thePath = nil;

}

 

#pragma mark  QLPreviewControllerDataSource

// 几个文件 显示

- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *) controller

{

        return 1;

}

 

//每个文档的URL

- (id <QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index

{

    if(thePath)

    {

        return [NSURL URLWithString:thePath];

    }

    else

    {

        WTLog(@"NONONONO");

        return nil;

    }

   

}

 

 

方法二：

使用uiwebView，直接播放

-(void)showWebview

{

    NSURL *url = [NSURL URLWithString:self.model.pdfUrl];

    NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:20.0f];

    [_wtWebView loadRequest:request];

    _wtWebView.delegate = self;

    

    _wtWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);

    

    _wtWebView.scalesPageToFit=YES;

    

    _wtWebView.multipleTouchEnabled=YES;

    

    _wtWebView.userInteractionEnabled=YES;

}
