如何从iPhone文档目录中读取pdf文件？

目前我正在iPhone应用程序中工作，我在资源文件夹中有一个pdf文件（本地pdf文件），然后我成功读取了该pdf文件（paper.pdf），下面我提到了读取本地pdf文件供您参考。

Example:

CFURLRef pdfURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("paper.pdf"), NULL, NULL);
pdf = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
CFRelease(pdfURL);

然后我尝试将pdf文件（来自URL）存储在NSDocument目录中，存储成功。

NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://www.msy.com.au/Parts/PARTS.pdf"]];

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
 NSString *documentsDirectory = [paths objectAtIndex:0]; 
 NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"myPDF11.pdf"];
 [pdfData writeToFile:filePath atomically:YES];

然后我尝试阅读该 pdf 文件（来自 NSDocument 目录），但我不知道，请帮助我。

提前致谢

它非常简单，请使用下面的代码将您的 pdf 从文档目录显示到 Webview

从文档目录加载 PDF

 - (void)viewDidLoad
 {
[super viewDidLoad];

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 367)];
webView.scalesPageToFit = YES;

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
 NSString *documentsDirectory = [paths objectAtIndex:0]; 
 NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"myPDF11.pdf"];

NSURL *targetURL = [NSURL fileURLWithPath:filePath];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];

[self.view addSubview:webView];
[webView release];
 }

从应用程序包资源文件夹加载 PDF

 - (void)viewDidLoad
 {
[super viewDidLoad];

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 367)];
webView.scalesPageToFit = YES;

NSString *path = [[NSBundle mainBundle] pathForResource:@"myPDF11" ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];

[self.view addSubview:webView];
[webView release];
 }
