iPhone：获取位于资源文件夹子文件夹中的文件路径

问题描述

我是新的iPhone编程。我想读取位于资源文件夹子文件夹中的文本文件的内容。

资源文件夹结构如下：

资源

1. Folder1 ----> Data.txt


2. Folder2 ----> Data.txt


3. Folder3 ----> Folder1 ----> Data.txt

有多个名为Data.txt的文件，如何访问每个文件夹中的文件？我知道如何读取文本文件，但如果资源结构类似于上面的结构，那么如何获得路径？

例如，如果我想从文件夹3访问Data.txt文件，我如何获得文件路径？

请建议。

  NSBundle * thisBundle = [NSBundle bundleForClass：[self class]]; 
 NSString * filePath = nil; 
 
 if（filePath = [thisBundle pathForResource：@DataofType：@txtinDirectory：@Folder1]）{
 
 theContents = [[NSString alloc] initWithContentsOfFile：filePath]; 
 
 //完成后，开发人员有责任释放内容
 
} 
  

请注意，您可以使用-pathForResource：ofType：inDirectory访问子目录中的ressources。

I am new to iPhone programming. I want to read the content of a text file located in a subfolder of the Resource folder.

The Resource folder structure is the following:

Resource

1. Folder1---->Data.txt
2. Folder2---->Data.txt
3. Folder3---->Folder1---->Data.txt

There are multiple files named "Data.txt", so how can I access the files in each folder? I know how to read the text file, but if the Resource structure is similar to the above structure then how can I get the path?

For example, if I want to access the "Data.txt" file from Folder3, how can I get the file path?

Please suggest.

解决方案

To continue psychotiks answer a full example would look like this:

NSBundle *thisBundle = [NSBundle bundleForClass:[self class]];
NSString *filePath = nil;

if (filePath = [thisBundle pathForResource:@"Data" ofType:@"txt" inDirectory:@"Folder1"])  {

    theContents = [[NSString alloc] initWithContentsOfFile:filePath];

    // when completed, it is the developer's responsibility to release theContents

}

Notice that you can use -pathForResource:ofType:inDirectory to access ressources in sub directories.
