Question

我可以像这样访问和显示Xcode包中的文件：

NSString *file = [[NSBundle mainBundle] pathForResource:@"1" ofType:@"pdf"];

现在我要做的是使用这个JSON填写文件的名称，它会获取正确的名称：

self.localFileName = [BT_strings getJsonPropertyValue:self.screenData.jsonVars:@"localFileName":@""];

如何将这两件事放在一起，以便我可以使用JSON名称调用Bundled文件？

以下是整个事情：

@synthesize localFileName;


- (void)viewDidLoad
{ [BT_debugger showIt:self:@"ZZZZZZZZZZ!!!"];
    [super viewDidLoad];

    self.localFileName = [BT_strings getJsonPropertyValue:self.screenData.jsonVars:@"localFileName":@""];

    self.localFileName = @""; // added this to make it work!!

    NSString *file=[[NSBundle mainBundle]pathForResource:self.localFileName ofType:@"pdf"];

    ReaderDocument *document = [ReaderDocument withDocumentFilePath:file password:nil];

    if (document != nil)
    {
        ReaderViewController *readerViewController = [[ReaderViewController alloc] initWithReaderDocument:document];
        readerViewController.delegate = self;

        readerViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        readerViewController.modalPresentationStyle = UIModalPresentationFullScreen;

        [self presentModalViewController:readerViewController animated:YES];
    }

}

    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);

- (void)dismissReaderViewController:(ReaderViewController *)viewController {
    [self dismissModalViewControllerAnimated:YES];
}

如果您从“self.localFilename”获取正确的文件名，那么除了将其传递给您的文件之外，您无需执行任何操作：

NSString * file = [[NSBundle mainBundle] pathForResource：self.localFileName ofType：@“pdf”];

Json和Bundle资源Xcode
