I'm using scrollview for image loading.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
dataPath = [documentsDirectory stringByAppendingPathComponent:#"/Images"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];
NSArray *docsArray = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:dataPath error:&error];
for (int i = 0; i < [docsArray count]; i++)
{
NSString *strPath = [docsArray objectAtIndex:i];
if([strPath containsString:[NSString stringWithFormat:#"%#_",strID]])
{
[imgArray addObject:[UIImage imageWithContentsOfFile:[NSString stringWithFormat:#"%#/%#",dataPath,strPath]]];
NSLog(#"%#%#",dataPath,strPath);
}
}
if([imgArray count]>0)
[self showImages];

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);
}
}
}
}
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);
I am using the code
NSArray *directoryNames = [NSArray arrayWithObjects:#"hats",#"bottoms",#"right",#"left",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
for (int i = 0; i < [directoryNames count] ; i++) {
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:i]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder
NSString *folderPath = [documentsDirectory stringByAppendingPathComponent:#"hats"]; // "right" is at index 2, per comments & code
NSString *filePath = [folderPath stringByAppendingPathComponent:#"IMAGE_NAME_HERE.PNG"];
NSData *imageData = UIImagePNGRepresentation(captureImage.image);
[imageData writeToFile:filePath atomically:YES];
}
to save however it always replaces itself so I can't save multiple photo's. How should I make it so that it will stop doing that without duplicating itself?
You're always saving to the same place, per this code:
NSString *folderPath = [documentsDirectory stringByAppendingPathComponent:#"hats"]; // "right" is at index 2, per comments & code
NSString *filePath = [folderPath stringByAppendingPathComponent:#"IMAGE_NAME_HERE.PNG"];
NSData *imageData = UIImagePNGRepresentation(captureImage.image);
[imageData writeToFile:filePath atomically:YES];
Looping through the array just saves everything to the 'hats' path every time. You're already calculating the place to store the image based on the array object, through the dataPath object. You just aren't doing anything with that. Instead, do this:
for (int i = 0; i < [directoryNames count] ; i++) {
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:i]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder
[imageData writeToFile:dataPath atomically:YES];
}
I am saving an image however it is just duplicating itself since I only set only one name however I want it to count up so that it wont replace itself. Is there any way to do this?
NSArray *directoryNames = [NSArray arrayWithObjects:#"hats",#"bottoms",#"right",#"left",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
for (int i = 0; i < [directoryNames count] ; i++) {
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:i]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder
NSString *folderPath = [documentsDirectory stringByAppendingPathComponent:#"hats"]; // "right" is at index 2, per comments & code
NSString *filePath = [folderPath stringByAppendingPathComponent:#"hats.PNG"]; // you maybe want to incorporate a timestamp into the name to avoid duplicates
NSData *imageData = UIImagePNGRepresentation(captureImage.image);
[imageData writeToFile:filePath atomically:YES];
}
Use timestamp value as filename to avoid duplicates
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];
