您发布的代码几乎是正确的，您只需要将文件路径设置为应用程序包中文件的路径。替换这部分代码：

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

 NSString *documentsDirectory = [paths objectAtIndex:0];

 NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];

只需让它从包中加载文件：

 NSString *pdfFileName = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:fileName];
