iphone将文件夹从包复制到文档 [英] iphone copying folder from bundle to documents

问题描述

我正在努力工作。我正在尝试将文件夹中的文件夹复制到文档目录。

I'm having the hardest time getting this to work. I'm trying to copy a folder from my bundle to the documents directory.

我要找的文件夹在这里：

the folder I'm trying to find is here:

... app / Resources / 12 /（一堆jpgs）

...app/Resources/12/(a bunch of jpgs)

NSString *myPath = [[[NSBundle mainBundle] resourcePath]stringByAppendingPathComponent:@"12"];
NSLog(@"%@",myPath);/// returns "..../MyApp.app/12"

NSArray *arrayOf12s = [[NSFileManager defaultManager]contentsOfDirectoryAtPath:myPath error:nil];

NSLog(@"%@",arrayOf12s);     ////always returns NULL

推荐答案

如何使用-contentsOfDirectoryAtPath中的NSError参数：错误：调用？

How about using the NSError argument in -contentsOfDirectoryAtPath:error: call?

NSString *myPath = [[[NSBundle mainBundle] resourcePath]stringByAppendingPathComponent:@"12"];
NSLog(@"%@",myPath);/// returns "..../MyApp/12"

NSError *error = nil;
NSArray *arrayOf12s = [[NSFileManager defaultManager]contentsOfDirectoryAtPath:resourceDBFolderPath error:&error];

if (error)
   NSLog(@"Error: %@", [error localizedDescription]);

NSLog(@"%@",arrayOf12s);     ////always returns NULL

它可能会对原因有所启发......

It might shine some light on the cause...
