need to access directory list in ios - ios

I need to create a folder and files in this path
/var/mobile/Containers/Data/
but when I look for it can't find the folder
my code >>
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDownloadsDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = #"/var/mobile/Containers";//[paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"MyNewFolder/myDB.db"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];

I dint really understood your problem . Hope this helps :
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *path = [paths objectAtIndex:0];
NSLog(#"Saving");
NSUserDefaults *prefs = [[NSUserDefaults alloc] init];
NSString *path1 = [NSString stringWithFormat:#"/var/mobile/Containers"];
NSString *dataPath = [path stringByAppendingPathComponent:path1];
dataPath = [dataPath stringByStandardizingPath];
filePath = [dataPath stringByAppendingPathComponent:#"MyNewFolder/myDB.db"];

Here's the iOS 8 approach Apple recommends to retrieve the location of the Documents directory:
// Returns the URL to the application's Documents directory.
- (NSURL *)applicationDocumentsDirectory
{
return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
}

Create Folder
//-- to select path from image--//
AppDelegate *del = (AppDelegate*)[[UIApplication sharedApplication]delegate];
NSString *dataPath=[del.databasePath copy];
NSString *Documentpath=[del.path_Folder_Document copy];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Fetch path for document directory
dataPath = (NSMutableString *)[documentsDirectory stringByAppendingPathComponent:#"/Images"];
Pathforimage=dataPath;
Add Folder if not Exist
if (![[NSFileManager defaultManager] createDirectoryAtPath:Pathforimage withIntermediateDirectories:NO attributes:nil error:nil])
{
//NSLog(#"directory... /Images already exist..");
}
else
{
//NSLog(#"directory created!");
}
NSString *pathforAudios=[NSString stringWithFormat:#"%#/Images_Audio",Documentpath];
if (![[NSFileManager defaultManager] createDirectoryAtPath:pathforAudios withIntermediateDirectories:NO attributes:nil error:nil])
{
//NSLog(#"directory... /Images already exist..");
}
else
{
//NSLog(#"directory created!");
}
//-- end of path --//
Save Image to Folder
//Save Image to Documents Directory
NSString *imagePath = [Pathforimage stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.jpg",Img_File_Name]];
[UIImageJPEGRepresentation(image, 0.1) writeToFile:imagePath atomically:YES];
imagePath=nil;
image=nil;
Delete Files/Folder
NSFileManager *fileMgr = [NSFileManager defaultManager];
NSError *error = nil;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *files = [fileMgr contentsOfDirectoryAtPath:documentsDirectory error:nil];
NSLog(#"files =%#",files);
NSString *Images_Folder = (NSMutableString *)[documentsDirectory stringByAppendingPathComponent:#"/Images"];
NSArray *fileArray = [fileMgr contentsOfDirectoryAtPath:Images_Folder error:nil];
for (NSString *filename in fileArray)
{
NSLog(#"Images =%#",filename);
[fileMgr removeItemAtPath:[Images_Folder stringByAppendingPathComponent:filename] error:NULL];
}
NSString *Images_Audio_Folder = (NSMutableString *)[documentsDirectory stringByAppendingPathComponent:#"/Images_Audio"];
NSArray *fileArray1 = [fileMgr contentsOfDirectoryAtPath:Images_Audio_Folder error:nil];
for (NSString *filename in fileArray1)
{
NSLog(#"Images_Audio =%#",filename);
[fileMgr removeItemAtPath:[Images_Audio_Folder stringByAppendingPathComponent:filename] error:NULL];
}

Create floder
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"/MyNewFolder"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath:dataPath]){
[fileManager createDirectoryAtPath:dataPath withIntermediateDirectories:YES attributes:nil error:&error]; //Create folder
}else{
NSLog(#"exist");
}
NSLog(#"dataPath:%#",dataPath);

how to delete the specific item in the document directory ios objective c

I want remove specific item from DocumentDirectory i.e I have 50 objects in the DocumentDirectory and i want to remove the 5 different elements from it. I used following code to get the DocumentDirectory objects.
NSURL *vedioURL;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory error:nil];
NSLog(#"files array %#", filePathsArray);
can any one Help me out to solve this problem
You can try the following approach
NSString *path = nil;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
path = [paths[0] stringByAppendingPathComponent:#"YOUR DIR"];
path = [path stringByAppendingPathComponent:#"YOUR FILE"];
NSError *error;
if ([[NSFileManager defaultManager] fileExistsAtPath:path])
{
if (![[NSFileManager defaultManager] removeItemAtPath:path error:&error]) //Delete it
{
NSLog(#"Delete file error: %#", error);
}
}
You can try like this way
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
if (filePathsArray.count >= 6) {
for (NSInteger i=filePathsArray.count-6; i < filePathsArray.count; i++) {
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:[filePathsArray objectAtIndex:i]];
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath]) {
NSError *error;
if (![[NSFileManager defaultManager] removeItemAtPath:filePath error:&error]) {
NSLog(#"Delete error: %#", error);
}
}
}
}

View the contents of Custom Directory in iOS

I am creating a directory inside my application.Is there a code to view the contents of the directory in xcode. For example in android you can create a custom directory and view its contents using a file manager application. Can the similar procedure be done in apple?
Here is the code which i use to create a directory?
bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier];
fileManager = [NSFileManager defaultManager];
myImageDirectory = [fileManager URLsForDirectory:NSApplicationSupportDirectory inDomains:NSUserDomainMask];
if ([myImageDirectory count] == 1){
NSLog(#"myImageDirectoryIs already present directory is already present");
}else{
directoryPath = [[myImageDirectory objectAtIndex:0] URLByAppendingPathComponent:bundleIdentifier];
NSLog(#"myImageDirectory directory name = %#",[directoryPath absoluteString]);
NSError *theError = nil;
if (![fileManager createDirectoryAtURL:directoryPath withIntermediateDirectories:NO attributes:nil error:&theError]){
NSLog(#"didnt write image data");
}else{
imagePath = [[directoryPath absoluteString] stringByAppendingPathComponent:[NSString stringWithFormat:#"/%#_%#_%#_image.jpg",dIdNo,iIdNo,[self currentDateandTime]]];
[imageData writeToFile:imagePath atomically:YES];
}
}
If your app is running in the simulator you'll need to use Finder. Go to the following directory:
/Users/<username>/Library/Application Support/iPhone Simulator/<iOS version>/Applications/<uuid>/Library/Application Support
If your app is running on the device you can use Xcode:
Connect the device
Choose menu option Window -> Organizer
Go to the Devices Tab
Click Applications under the device menu on the left
Pick your Application
The directory contents will be listed and you can optionally download everything.
try this...
to create a directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"/MyFolder"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
to retrieve contents from directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *customDirectory = [documentsDirectory stringByAppendingPathComponent:#"/MyFolder"];
NSError * error;
NSArray *directoryContents = [[NSFileManager defaultManager]
contentsOfDirectoryAtPath:customDirectory error:&error];
for(NSString *strFile in directoryContents)
{
NSString *strVideoPath = [NSString stringWithFormat:#"%#/%#",customDirectory,strFile];
if([[strVideoPath pathExtension] isEqualToString:#"mp4"] || [[strVideoPath pathExtension] isEqualToString:#"mov"])
{
[urlArray addObject:strVideoPath];
}
}
you can get the contents of the directory(MYNewFolder) from below code:
NSString *stringPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:#"MYNewFolder"];
NSArray *filePathsArray = [[NSFileManager defaultManager]
subpathsOfDirectoryAtPath:stringPath
error:nil];
for ( NSString *apath in filePathsArray )
{
NSLog(#"inside the file path array=%d",apath);
}
Method
-(NSArray *) getObjectsInDirectory:(NSString *)directory {
NSFileManager * fm = [NSFileManager defaultManager];
NSError * error = nil;
NSArray * result = [fm contentsOfDirectoryAtPath:directory error:&error];
return result;
}
How-To
NSString * documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSArray * files = [self getobjectsInDirectory:documentsPath];
This code is used to get an array of the files within the documents directory.
Viewing the Files
NSLog(#"%#", files);
Check this class out, it allows you to simplify so many things in iOS: Atomic Class

Files added to documents directory shows up in Simulator but nothing in iphone

This is the code I'm using and it works in simulator but showing nothing in idevice. If I add an folder or a file through ifunbox it shows up in device though. Do I need any permission to create or add files?
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat: #"/Folders/%#", self.txtFolder.text]];
NSLog(#"%#", dataPath);
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
{
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
[sec1Contents addObject:self.txtFolder.text];
sec1 = [NSArray arrayWithArray:sec1Contents];
[self.tblFiles reloadData];
}
thanks in advance.
Use this code :
NSURL *allitemsImageurl =[NSURL URLWithString: url];
NSData *allItemsImageData = data1; // Load XML data from web
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * documentsDirectoryPath = [paths objectAtIndex:0];
NSString *st1=[ #"img_" stringByAppendingString:[NSString stringWithFormat:#"%d.png",imageCount]];
NSString *allitemsImagePath = [documentsDirectoryPath stringByAppendingPathComponent:st1];
NSLog(#"%#",allitemsImagePath);
[allItemsImageData writeToFile:allitemsImagePath atomically:TRUE];

How to call an directory when saving

II have created multiple directories like this
NSArray *directoryNames = [NSArray arrayWithObjects:#"hats",#"bottoms",#"right",#"left",nil];
however I do not know how to save into a specific directory.I save like this
NSString *filePath = [folderPath stringByAppendingPathComponent:#"IMAGE_NAME_HERE.PNG"];
NSData *imageData = UIImagePNGRepresentation(captureImage.image);
[imageData writeToFile:filePath atomically:YES];
However I do not know how to specify the directory. I only want the user to save into directory hats. How can I do this?
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsPath = [paths objectAtIndex:0];
NSString *imageCacheDirPath = [docsPath stringByAppendingPathComponent:#"hats"];
NSString *imageCachePath = [imageCacheDirPath stringByAppendingPathComponent:#"IMAGE_NAME_HERE.PNG"];
if (![[NSFileManager defaultManager] fileExistsAtPath: imageCacheDirPath])
[[NSFileManager defaultManager] createDirectoryAtPath:imageCacheDirPath
withIntermediateDirectories:NO
attributes:nil
error:NULL];
[[NSFileManager defaultManager] createFileAtPath:imageCachePath
contents:dataObj
attributes:nil];

How to get the list of directores in NSDocumentDirectory?

I have created some directories in NSDocumentDirectory as
if (![tbxCreateFolder.text isEqualToString:#""]) {
NSArray *arrPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryStr = [arrPaths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectoryStr stringByAppendingPathComponent:[NSString stringWithFormat:#"/%#",tbxCreateFolder.text]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]){
NSError* error;
if([[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]){
NSLog(#"success");
//Perfrom DB Insertation
}
else
{
NSLog(#"[%#] ERROR: attempting to write create MyFolder directory", [self class]);
NSAssert( FALSE, #"Failed to create directory maybe out of disk space?");
}
}
}
Now i want to get the list of directories that i have created in document folder but response is
NSArray *arrPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePathString = ([arrPaths count] > 0) ? [arrPaths objectAtIndex:0] : nil;
NSLog(#"dirContents %#",basePathString);
Response is:
/Users/amir/Library/Application Support/iPhone Simulator/6.1/Applications/7003E8D5-CCBB-4E54-896B-F4BD2F4D2CB1/Documents
Here is the code:
NSString *documentDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
// create directory named "test"
[[NSFileManager defaultManager] createDirectoryAtPath:[documentDirPath stringByAppendingPathComponent:#"test"] withIntermediateDirectories:YES attributes:nil error:nil];
// retrieved all directories
NSLog(#"%#", [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentDirPath error:nil]);
NSArray *paths = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentDirPath error:nil];
BOOL isDir = NO;
for (NSString *path in paths) {
if ([fileManager fileExistsAtPath:path isDirectory:&isDir] && isDir) {
// path is directory
}
}
You could always enumerate the contents of the top level directory using -fileExistsAtPath:isDirectory: like this:
NSFileManager *sharedFileManager = [NSFileManager defaultManager];
NSDirectoryEnumerator *files = [sharedFileManager enumeratorAtPath:yourPath];
for (NSString *path in files) {
BOOL isDirectory = NO;
[sharedFileManager fileExistsAtPath:path isDirectory:&isDirectory];
if (isDirectory) {
// you found a directory, so do what you will with it
}
}
You can do this with few simple lines of code
NSString *documentDirectoryPath = // Initialize with Documents path
BOOL isDir = NO;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *files = [fileManager contentsOfDirectoryAtPath:documentDirectoryPath error:NULL];
NSMutableArray *directoriesPaths = [NSMutableArray array];
for (NSString *filePath in files) {
if ([fileManager fileExistsAtPath:filePath isDirectory:&isDir] && isDir) {
[directoriesPaths addObject:filePath];
}
}
NSLog(#"directories %#", directoriesPaths);
try this,
NSArray *arrPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *strFilePath = [[arrPath objectAtIndex:0]
[[NSFileManager defaultManager] createDirectoryAtPath:[strFilePath stringByAppendingPathComponent:#"Sample"] withIntermediateDirectories:YES attributes:nil error:nil];
