目標C，無法加載存儲在資源文件夾在Xcode

Question

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDicrectory = [paths objectAtIndex:0]; 
NSString *filePath = [documentsDicrectory stringByAppendingPathComponent:@"libdata.xml"]; 
NSString *xmlString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL]; 

xml文件我保存在文件夾資源的XML文件（不小約140K的大小）在Xcode並試圖加載XML文件解析它。但xmlString獲取零。這段代碼有什麼問題？ 在此先感謝

使用NSBundleClass：

NSString * filePath = [ [ NSBundle mainBundle ] pathForResource: @"libdata" ofType: @"xml" ];
