i want to know the contents in a directory either its documents or any other.
if there is a file or more than one i need those file names.
actually i am creating the export directory in documents directory..
and if export is empty then i am copying the zip file from main bundle to export folder
but the following code is not working. though the export is empty its not going in to that if block..r there any hidden files..? and in the last for loop its not doing any thing.
how to do this.
please help me out
self.fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
self.documentsDir = [paths objectAtIndex:0];
//creating folder 'export' to recieve the file from iTunes
NSString *srcFilePath = [NSString stringWithFormat:#"%#/export", self.documentsDir];
[fileManager createDirectoryAtPath:srcFilePath
withIntermediateDirectories:NO
attributes:nil
error:nil];
//copying the zip file into exprort from bundle if export is empty
if(![fileManager fileExistsAtPath:srcFilePath]) {
NSLog(#"File exists at path: %#", srcFilePath);
NSString *resZipfile = [[NSBundle mainBundle] pathForResource:#"sample" ofType:#"zip"
inDirectory:#"pckg"];
NSLog(#"zip file path ...%#", resZipfile);
NSData *mainBundleFile = [NSData dataWithContentsOfFile:resZipfile];
[[NSFileManager defaultManager] createFileAtPath:srcFilePath
contents:mainBundleFile
attributes:nil];
}
NSString *eachPath;
NSDirectoryEnumerator *dirEnum = [fileManager enumeratorAtPath:srcFilePath];
for(eachPath in dirEnum) NSLog(#"FILE: %#", eachPath);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSFileManager *manager = [[NSFileManager alloc] init];
NSDirectoryEnumerator *fileEnumerator = [manager enumeratorAtPath:documentsPath];
for (NSString *filename in fileEnumerator) {
// Do something with file
}
[manager release];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsPath = [paths objectAtIndex:0];
NSString *srcFilePath = [NSString stringWithFormat:#"%#/export", self.documentsDir];
BOOL isDir;
BOOL exists = [[NSFileManager defaultManager] fileExistsAtPath:srcFilePath] isDirectory:&isDir];

NSData *mainBundleFile = [NSData dataWithContentsOfFile:resZipfile];
[[NSFileManager defaultManager] createFileAtPath:srcFilePath

Swift 4 version:
guard let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first,
let fileEnumerator = fileManager.enumerator(atPath: path) else {
return
}
let fileNames = fileEnumerator.flatMap { $0 as? String } //Here You will have Array<String> with files in current folder and subfolders of your application's Document directory

I am using the following line of code to save my file of yoyo.txt in the Documents folder ::
NSString *docDir = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents"];
NSLog(#"docDir is yoyo :: %#", docDir);
NSString *FilePath = [docDir stringByAppendingPathComponent:#"yoyo.txt"];
However, I wish to save my file in a folder of yoyo i.e. inside the Documents folder i.e. I want to create another folder named as "yoyo" and then save my file of yoyo.txt into it. How can I do that ?? Thanks.
Here is a sample code (assume manager is [NSFileManager defaultManager]):
BOOL isDirectory;
NSString *yoyoDir = [docDir stringByAppendingPathComponent:#"yoyo"];
if (![manager fileExistsAtPath:yoyoDir isDirectory:&isDirectory] || !isDirectory) {
NSError *error = nil;
NSDictionary *attr = [NSDictionary dictionaryWithObject:NSFileProtectionComplete
forKey:NSFileProtectionKey];
[manager createDirectoryAtPath:yoyoDir
withIntermediateDirectories:YES
attributes:attr
error:&error];
if (error)
NSLog(#"Error creating directory path: %#", [error localizedDescription]);
}
+(void)createDirForImage :(NSString *)dirName
{
NSString *path;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
path = [[paths objectAtIndex:0] stringByAppendingPathComponent:dirName];
NSError *error;
if (![[NSFileManager defaultManager] fileExistsAtPath:path]) //Does directory already exist?
{
if (![[NSFileManager defaultManager] createDirectoryAtPath:path
withIntermediateDirectories:NO
attributes:nil
error:&error])
{
NSLog(#"Create directory error: %#", error);
}
}
}
Here dataPath will be the final path for saving your file
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"/yoyo"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]){
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
}
dataPath = [dataPath stringByAppendingPathComponent:#"/yoyo.txt"];
i have one subfolder in Resources with name SketchImages which contains 300 PNG images, what i need to do is on the startup of my app copy this folder in document folder of iphone sdk, i am trying the following code with no luck
BOOL success;

stringByAppendingPathComponent:#"DB"];
//[fileManager createDirectoryAtPath: documentDBFolderPath attributes:nil];
[fileManager copyItemAtPath:resourceDBFolderPath toPath:documentDBFolderPath
error:&error];
}
any help will be highly appriciated
You use the wrong subfolder name:
NSString *resourceDBFolderPath = [[[NSBundle mainBundle] resourcePath]
stringByAppendingPathComponent:#"SketchImages"];

I am trying to copy a couple of image files from my MainBundle/SampleImages folder to the application NSDocumentDirectory/Library folder, but am unable to do so. I have checked that the images are in .app/Mainbundle/SampleImages directory and I have also checked that the Library folder is being created in the NSDocumentsDirectory, but no files are copied.
I have tried two approaches, given below, but with no success.
here is the code that I am using to copy files.
First Method
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentLibraryFolderPath = [documentsDirectory stringByAppendingPathComponent:#"Library"];
NSString *resourceSampleImagesFolderPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"SampleImages"];
NSData *mainBundleFile = [NSData dataWithContentsOfFile:resourceSampleImagesFolderPath];
[[NSFileManager defaultManager] createFileAtPath:documentLibraryFolderPath
contents:mainBundleFile
attributes:nil];
Second Method
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentSampleImagesFolderPath = [documentsDirectory stringByAppendingPathComponent:#"Library"];
NSString *resourceSampleImagesFolderPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"SampleImages/"];
[fileManager createDirectoryAtPath: documentSampleImagesFolderPath attributes:nil];
if([fileManager copyItemAtPath:resourceSampleImagesFolderPath toPath:documentSampleImagesFolderPath error:&error]) {
NSLog(#"success");
}
else {
NSLog(#"Failure");
NSLog(#"%d",error);
}
I have spent a couple of hours looking for a solution, any help here would be appreciated greatly.
Thank You

I got it done with the second method by changing it bit.
There is no need for creating the directory as the SDK docs say that the destination directory must not exist.
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentDBFolderPath = [documentsDirectory stringByAppendingPathComponent:#"Library"];
NSString *resourceDBFolderPath = [[[NSBundle mainBundle] resourcePath]
stringByAppendingPathComponent:#"SampleImages"];
[fileManager copyItemAtPath:resourceDBFolderPath toPath:documentDBFolderPath error:&error];
I current have everything setup to read from the documents directory and write to it , but Cannot do it because the file doesnt exist yet.
How is a file created within the code?
If you already have a template version of the document in your application's bundle then you should be able to write it to the application's document directory using something similar to the following. I haven't tested this code so I've probably got a few things wrong but that's the general idea.
- (void) applicationDidFinishLaunching {
NSArray* directories = NSSearchPathsForDirectoriesInDomain(NSDocumentsDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [directories objectAtIndex: 0];
NSString* path = [documentsDirectory stringByAppendingPathComponent: #"Something.plist"];
if (![[NSFileManager sharedInstance] fileExistsAtPath: path]) {
NSString* infoTemplatePath = [[NSBundle mainBundle] pathForResource: #"Something" ofType: #"plist"];
NSDictionary* info = [NSDictionary dictionaryWithContentsOfFile: infoTemplatePath];
[info writeToFile: path];
}
}
Use NSFileManger's fileExistsAtPath: to see if the file exist. If not create it before going on to the code that requires the file.
This one works better for me:
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentDBFolderPath = [documentsDirectory stringByAppendingPathComponent:#"*.db"];
if (![fileManager fileExistsAtPath:documentDBFolderPath])
{
NSString *resourceDBFolderPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"*.db"];
[fileManager copyItemAtPath:resourceDBFolderPath toPath:documentDBFolderPath error:&error];
}
