I have to access image from document library in iOS 6 .
strImgSign = [NSString stringWithFormat:#"%#/Documents//%#", NSHomeDirectory(),strImgSign];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
NSString *strImgSign = [[arrNameFinal objectAtIndex:indexPath.row] objectForKey:#"signimage"];

But image access in iOS 7,8 is perfect Working.
You should not build the directory from the NSHoneDirectory or use path separators in you string.
Correct way to build directories:
NSString *imagePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents"];
imagePath = [imagePath stringByAppendingPathComponent:strImgSign];
But even better and only correct way is to use the correct directory:
NSString *documentPath =[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSString *imagePath = [documentPath stringByAppendingPathComponent:strImgSign];
There is an extra / in your path:
strImgSign = [NSString stringWithFormat:#"%#/Documents//%#", NSHomeDirectory(),strImgSign];
Change that to:
strImgSign = [NSString stringWithFormat:#"%#/Documents/%#", NSHomeDirectory(),strImgSign];
But as mentioned by #rckoenes, it's not the correct way of building file system paths. If your image is located in document directory you can use:
NSString *docDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *yourImagePath = [docDirectory stringByAppendingPathComponent:strImgSign];
But I'm not sure how it worked for you in iOS 7 and iOS 8
NSString *filename = [filepart lastObject];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString documentsDirectory = [paths objectAtIndex:0];
NSString inboxPath = [documentsDirectory stringByAppendingPathComponent:#"Inbox"];
NSString *filePath = [inboxPath stringByAppendingPathComponent:filename];

I have a .zip folder which contains some images. I want it to unzip into Documents directory in iOS device. I tried with the following link,
download and unzip file in iOS-Stack Overflow
Here is the code that I tried in my app,
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask,
YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filepath = [documentsDirectory stringByAppendingPathComponent:#"Obj.zip"];
ZipArchive *zipArchive = [[ZipArchive alloc] init];
[zipArchive UnzipOpenFile:filepath Password:#""];
[zipArchive UnzipFileTo:[documentsDirectory stringByAppendingPathComponent:#"Obj"] overWrite:YES];
[zipArchive UnzipCloseFile];
And then I printed the all files in Document Directory, but the Obj.zip is the only file(Obj.zip is the file that wants to unzip) that exist in the Documents Directory. How can I done this?
Thanks in Advance!
Use SSZipArchive. Here is a sample code. https://github.com/soffes/ssziparchive
Also I believe the unzipping would create a folder in documents directory which would contain the files. Please check that
NSString *zipPath = [[NSBundle mainBundle] pathForResource:zipFileName ofType:#"zip"];
NSString *destinationPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];
Update : Get zip file from documents directory
NSString *filename = #"MyZipFile.zip";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString * zipPath = [documentsDirectory stringByAppendingPathComponent:filename];
NSString *destinationPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];
I'm working with Objective C (IOS) and I found this code:
Person *aPerson = <#Get a Person#>;
NSString *archivePath = <Path for the archive#>;
BOOL success = [NSKeyedArchiver archiveRootObject:aPerson toFile:archivePath];
I would like to know what the archivePath should be to save the file in documents directory.
Thank you
To figure out archivePath:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *archivePath = [documentsPath stringByAppendingPathComponent:#"Person"];
I have text file text.txt in my xcode project and I need to write NSString init from my iOS app. I've tried this code
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex: 0];
NSString *docFile = [docDir stringByAppendingPathComponent: #"text.txt"];
NSString *content = #"Test";
[content writeToFile: docFile atomically: NO];
But it doesn't work for me... So can you help me with it?
this worked for me
//Method writes a string to a text file
-(void) writeToTextFile{
//get the documents directory:
NSArray *paths = NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
//make a file name to write the data to using the documents directory:
NSString *fileName = [NSString stringWithFormat:#"%#/text.txt",
documentsDirectory];
//create content - four lines of text
NSString *content = #"Test";
//save content to the documents directory
[content writeToFile:fileName
atomically:NO
encoding:NSStringEncodingConversionAllowLossy
error:nil];
}

Problem in writing to a file in application bundle
I am trying to write a String to a file using the following code :

NSLog(#"Path : , %#", file);
NSError *error=NULL;
NSString *data=#"teleiwne";
[data writeToFile:file atomically:YES encoding:NSUTF8StringEncoding error:&error];

I don't get any error but nothing is written to file
I tried the following code and it worked :
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *appFile = [documentsDirectory stringByAppendingPathComponent:#"set.txt"];
NSString *data=#"Kostas";
[data writeToFile:appFile atomically:YES];
NSString *myData = [NSString stringWithContentsOfFile:appFile];
NSLog(#"Data : %# ",myData);
You aren't allowed to write to the App directory. Try writing to the Documents directory inside that app folder.
NSString *data = #"testData";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *appFile = [documentsDirectory stringByAppendingPathComponent:#"settings.txt"];
[data writeToFile:appFile atomically:YES];
I need to search a file in documents directory of iOS but i don't know the extension of that file. How to search the file without extension.
Below is the code if you know the filename.extension(abc.txt). How can i search for the same file with jsut filename(abc)
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"abc.txt"];

NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *directoryContent = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil];
NSString *fileWithExt = nil;
for (NSString *file in directoryContent )
{
if([file stringByDeletingPathExtension] isEqualsTo:#"abc"]
{
fileWithExt = file;
break;
}
}
P.S. : The fileWithExt will contain the first file with name abc
