JSON和捆綁資源的Xcode

Question

我可以訪問和顯示來自Xcode的捆綁像這樣的文件：

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

現在我想要做的就是使用此JSON這確實給我拿在文件的名稱填寫正確的名稱：

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

如何將這兩個東西放在一起，以便我可以使用JSON名稱調用捆綁文件？

這裏是整個事情：

{ [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.delegate = self; 

     readerViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

     [self presentModalViewController:readerViewController animated:YES]; 
    } 

}

如果從「self.localFilename」得到正確的文件名，那麼你需要做什麼，但它傳遞給你的文件爲：

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