循环浏览目录并获取所有文件和文件夹的路径 [英] Cycle through a directory and get paths of all the files and folders

问题描述

Hello在那里我坚持这个东西，我需要循环通过一定的 dir ，我需要得到所有的文件名，并得到路径作为一个变量。

Hello there im stuck on this thing where i need to cycle through a certain dir that i need to get all the file names from and get there paths as a variable.

我知道如何创建一个循环，但是为了获取目录的内容，我不知道。

I know how to create a loop, but to get the directory's contents, I do not.

推荐答案

尝试这样：

// If your folder is a document.
NSString *docsDir = [NSHomeDirectory() stringByAppendingPathComponent:  @"Documents"];
// else you can give your folder path as well, if you know 
// for example like this NSString *docsDir = @"user/desktop/testFolder"

NSFileManager *localFileManager = [NSFileManager defaultManager];
NSDirectoryEnumerator *dirEnum = [localFileManager enumeratorAtPath:docsDir];
NSString *file = nil;
NSData *fileContents = [NSData data];
while ((file = [dirEnum nextObject])) 
{
   NSLog(@"your file name%@",file); // This will give your filename
   // Now for getting file path follow below.
   // here we are adding path to filename.
   NSString *fileNamePath = [docsDir stringByAppendingPathComponent:file];
   NSLog(@"your fileNamePath%@",fileNamePath); // This will give your filename path
   fileContents = [NSData dataWithContentsOfFile:fileNamePath]; // This will store file contents in form of bytes

}
