以下是您在本地阅读和存储PDF文件的方法：

首先创建UIWebView并包含＆lt;＆lt; UIWebViewDelegate ＆gt;＆gt;

  NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
  NSString *documentsPath = [paths objectAtIndex:0];
  NSString *filePath = [documentsPath stringByAppendingPathComponent:@"YourPDF.pdf"]; 
 if(![[NSFileManager defaultManager] fileExistsAtPath:filePath]){
           // download file , here "https://s3.amazonaws.com/hgjgj.pdf" = pdf downloading link
         NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"https://s3.amazonaws.com/hgjgj.pdf"]];
            //Store the downloaded file  in documents directory as a NSData format
         [pdfData writeToFile:filePath atomically:YES];
    }

     NSURL *url = [NSURL fileURLWithPath:filePath];
     NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
     [yourWebView setUserInteractionEnabled:YES];
     [yourWebView setDelegate:self];
     yourWebView.scalesPageToFit = YES;
     [yourWebView loadRequest:requestObj];

或者，如果您只是想从资源文件夹中读取/加载pdf，那么只需执行以下操作：

     NSString*  filePath= [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"pdf"]];
    /// or you can even read docs file as : pathForResource:@"sample" ofType:@"docx"]
     NSURL *url = [NSURL fileURLWithPath:filePath];
     NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
     [yourWebView setUserInteractionEnabled:YES];
     [yourWebView setDelegate:self];
     yourWebView.scalesPageToFit = YES;
     [yourWebView loadRequest:requestObj];
