怎么确保在向Iphone真机上加载程序时，能够把文件都加载到/Documents/里面

boolwriteApplicationData(NSData*data, NSString*fileName)

   {

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

       NSString*documentsDirectory = [paths objectAtIndex:0];

       if(!documentsDirectory) {

           NSLog(@"Documents directory not found!");

           returnNO;

       }

       NSString*appFile = [documentsDirectory stringByAppendingPathComponent:fileName];

       return([data writeToFile:appFile atomically:YES]);

   }

    

NSData*applicationDataFromFile(NSString*fileName)

   {

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

       NSString*documentsDirectory = [paths objectAtIndex:0];

       NSString*appFile = [documentsDirectory stringByAppendingPathComponent:fileName];

       NSData*myData = [[[NSDataalloc] initWithContentsOfFile:appFile] autorelease];

       returnmyData;

   }
