The Rewrite Has Arrived: TOMFileManager.

TKMFileManager

TKMFileManager is a simple tool to manage your iOS App's files, written in Objective-C. Instead of using NSFileManager and the lengthy amount of code needed for a simple operation, you can write it in just one line with TKMFileManager!
To be perfectly honest, there's not much that is super special about it - except instead of writing this:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *newDirectory = [documentsDirectory stringByAppendingPathComponent:@"/newDirectory"];

if (![[NSFileManager defaultManager] fileExistsAtPath:newDirectory])
{
	[[NSFileManager defaultManager] createDirectoryAtPath:newDirectory withIntermediateDirectories:NO attributes:nil error:nil];
}

You can simply write this:

TKMFileManager *manager = [[TKMFileManager alloc] init];
[manager createSubdirectory:@"/NewDirectory" inDirectory:manager.documentsDirectory];

Sure, almost anyone could write something like this, but why bother when its already written for you - for free!

Plus, this is the only file manager on GitHub with Appldoc style documentation, which can be found here

Installation

Without CocoaPods

1. Simply copy TKMFileManager.h and TKMFileManager.m into your project's files.
   

2. In the file in which you'd like to use TKMFileManager, add the following line to your import statements:

#import "TKMFileManager.h"

With CocoaPods

Simply add the following to your podfile:

pod 'TKMFileManager', '~> 1.0'

Then run a pod install inside your terminal, or from CocoaPods.app.

Usage

To create a new TKMFileManager object (named manager in this example), simply write:

TKMFileManager *manager = [[TKMFileManager alloc] init];

If, for some reason, you don't want to initialize it right away, you can simply write: ```Objective-C TKMFileManager *manager = [TKMFileManager alloc]; ``` However, before you can use it, you ***MUST*** initialize the TKMFileManager object: ```Objective-C [manager init]; ```
Now that you've created your TKMFileManager object, you're reading to begin managing your files:

Creating A New Directory

TKMFileManager does NOT default to any specific directory, so when making a new directory you will need to specify the FULL path of your new directory. Luckily, this is easy as TKFileManager does provide easy access to the directories you're likely to use:

manager.documentsDirectory //Path for the Documents Directory
manager.mainBundleDirectory //Path for the Main Bundle's directory

So, to create a new directory in your app's Documents Directory, you simply need to say:

[manager createDirectory:[manager.documentsDirectory stringByAppendingPathComponent:@"NewDirectory"]];

Alternatively, you can accomplish this by using the createSubdirectory method:

[manager createSubdirectory:@"NewDirectory" inDirectory:manager.documentsDirectory];

To make things easier for you, createSubdirectory is smart enough to add "/" in front of your subdirectory's name, should you forget to.
When using createDirectory you will either need to have the "/" already included in your path's string, or you'll need to use stringByAppendingPathComponent.

Copying A Directory

Copying a directory makes a copy of the directory's files in a new location, while leaving the files in the original directory intact.
To copy a directory, you need to have the full path to the directory you wish to copy and the full path of the directory to wish you would like to copy it. If the destination directory does not exist, it will be created. For this example, we will copy the contents of the mainBundleDirectory to the documentsDirectory:

[manager copyDirectory:manager.mainBundleDirectory toDirectory:manager.documentsDirectory];

Note: that this does not create a "mainBundle" subdirectory in the Documents Directory, but rather it copies the contents of mainBundleDirectory directly to documentsDirectory.
If you wish for the contents to be copied to a subdirectory of the Documents Directory, you will first need to create it and then copy into it:

NSString *mainBundleInDocuments = [manager.documentsDirectory stringByAppendingPathComponent:@"MainBundleFiles"];
[manager copyDirectory:manager.mainBundleDirectory toDirectory:mainBundleInDocuments];

Moving A Directory

Moving a directory moves the a directory's files to a new location. The files are will no longer be able to be found the original directory, as they no longer exist there. If the destination directory does not exist, it will be created.
Like copying a directory, when moving a directory you must have the full path of the source directory and the destination directory:

NSString *mainBundleInDocuments = [manager.documentsDirectory stringByAppendingPathComponent:@"MainBundleFiles"];
[manager moveDirectory:manager.mainBundleDirectory toDirectory:mainBundleInDocuments];

NOTE: It is NOT recommended that you move the contents of mainBundleDirectory to any other directory.

Deleting A Directory

Deleting a directory will delete it's contents and the directory itself from the parent directory.
To delete a directory, you simple need to use the deleteDirectory method:

//(this example assumes "mainBundleInDocuments" is a valid variable)
[manager deleteDirectory:mainBundleInDocuments];

If the directory you are attempting to delete does not exist, nothing will happen.

Copying A File

If you know a file's full path, you can copy it to a directory (if the destination directory doesn't exist, it will be created):

[manager copyFile:[manager.mainBundleDirectory stringByAppendingPathComponent:@"default.n64skin"] toDirectory:manager.documentsDirectory];

Moving A File

If you know a file's full path, you can move it to a directory (if the destination directory doesn't exist, it will be created):

[manager moveFile:[manager.mainBundleDirectory stringByAppendingPathComponent:@"default.2600skin"]  toDirectory:manager.documentsDirectory];

Remember: If you move a file, it will no longer be in the original directory

Deleting A File

If you know a file's full path, you can delete it with the deleteFile method:

[manager deleteFile:[manager.documentsDirectory stringByAppendingPathComponent:@"testROM.z64"]];

Getting A File's Path

If you know what directory a file is in, you can get it's full path be using the getFile method:

NSString *dogeMemePath = [manager getFile:@"doge.png" inDirectory:manager.documentsDirectory];

This will search through the directory & its subdirectories, and will return the full path for your file (handy if you don't know if its in a subdirectory or not).

But, what if you don't know quite where a file's stored? Well, with TKMFileManager's exclusive findAndGetFile method, it will search all available directories (currently only Main Bundle & Documents) and all their subdirectories until it finds your file:

NSString *triggeredMemePath = [manager findAndGetFile:@"triggered.png"];

This feature also extends to moving, copying, and deleting a file, like so:

[manager findAndCopyFile:@"repost.png" toDirectory:manager.documentsDirectory];
[manager findAndMoveFile:@"moveItSomewhereElsePatrick.png" toDirectory:manager.documentsDirectory];
[manager findAndDeleteFile:@"harambe.png"];
