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;

}
