我可以像这样访问和显示来自 Xcode 包的文件：

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

现在我想做的是使用这个 JSON 填写文件的名称，它确实为我获取了正确的名称：

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

如何将这两件事放在一起，以便可以使用 JSON 名称调用捆绑文件？

这是整个事情：

@implementation ReaderDemoController
@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];
    }

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}




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

如果您从“self.localFilename”中获得正确的文件名，那么您只需将其传递给您的文件，如下所示：

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