I create two file paths with this code:
NSString *fileName = [[self genRandStringLength:15] stringByAppendingString:#".mp4"];
NSString *finalFilePath = [self.videoFiles stringByAppendingString:fileName];
NSString *tmpFile = [NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:#"temp.mp4"]];
[[NSFileManager defaultManager] removeItemAtPath:tmpFile error:NULL];
Then i have some code to create video file and the i want to save it in the Document Folder:
[[NSFileManager defaultManager] copyItemAtPath:tmpFile toPath:finalFilePath error:&err];
And i get this error:
Error Domain=NSCocoaErrorDomain Code=4 "The file “temp.mp4” doesn’t exist."
UserInfo={NSSourceFilePathErrorKey=/private/var/mobile/Containers/Data/Application/E5B7BBCB-311F-41A3-949D-8A309F535C95/tmp/temp.mp4, NSUserStringVariant=(

), NSDestinationFilePath=/var/mobile/Containers/Data/Application/E5B7BBCB-311F-41A3-949D-8A309F535C95/Documents/VideoFiles/0iWDmhLvbbzM6SE.mp4, NSFilePath=/private/var/mobile/Containers/Data/Application/E5B7BBCB-311F-41A3-949D-8A309F535C95/tmp/temp.mp4, NSUnderlyingError=0x12f0099b0 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}
Any idea what can be the problem?
Just for some checking i try to copy the video to the iPhone Photo library with :
UISaveVideoAtPathToSavedPhotosAlbum(tmpFile, self, nil, nil);
And it's work fine, so the file is exist.
Use this code
NSString *fileName = [[self genRandStringLength:15] stringByAppendingString:#".mp4"];
NSString *finalFilePath = [self.videoFiles stringByAppendingString:fileName];
NSString *tmpFile = [NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:#"temp.mp4"]];
NSFileManager *fileManager = [NSFileManager defaultManager];
BOOL success = [fileManager fileExistsAtPath:tmpFile];
if (success)
{
[[NSFileManager defaultManager] copyItemAtPath:tmpFile toPath:finalFilePath error:&err];
[[NSFileManager defaultManager] removeItemAtPath:tmpFile error:NULL];
}

I'm trying to copy a json file from the application bundle to the Document directory, but surprisingly i'm not able to do that. Here's the code:
NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [array lastObject];
NSString *path = [docDir stringByAppendingPathExtension:#"themes.json"];
if (![[NSFileManager defaultManager] fileExistsAtPath:path])
{
NSString *themesPath = [[NSBundle mainBundle] pathForResource:#"themes" ofType:#"json"];
NSError *error = nil;
[[NSFileManager defaultManager] copyItemAtPath:themesPath toPath:path error:&error];
if (error)
NSLog(#"Error %#", error);
}
It produces the following error:
Error Domain=NSCocoaErrorDomain Code=513 "The operation couldn’t be completed. (Cocoa error 513.)" UserInfo=0x194a0e90 {NSSourceFilePathErrorKey=/var/mobile/Applications/ACED3EF9-B0D8-49E8-91DE-37128357E509/Frinder.app/themes.json, NSUserStringVariant=(

), NSFilePath=/var/mobile/Applications/ACED3EF9-B0D8-49E8-91DE-37128357E509/Frinder.app/themes.json, NSDestinationFilePath=/var/mobile/Applications/ACED3EF9-B0D8-49E8-91DE-37128357E509/Documents.themes.json, NSUnderlyingError=0x194a0400 "The operation couldn’t be completed. Operation not permitted"}
After a search i've found this question and tried to modify my code as follows:
if (![[NSFileManager defaultManager] fileExistsAtPath:path])
{
NSString *themesPath = [[NSBundle mainBundle] pathForResource:#"themes" ofType:#"json"];
NSData *data = [NSData dataWithContentsOfFile:themesPath];
BOOL success = [[NSFileManager defaultManager] createFileAtPath:path contents:data attributes:nil];
if (!success)
NSLog(#"Fail");
}
but it doesn't work either. success variable is NO. The last thing i tried was:
[data writeToFile:path atomically:YES];
but still in vain. it returns NO.
I need to note that the issue arises on a device only. On a simulator it works all right.
Can anybody give me a clue?
The first example is correct on one thing:
[docDir stringByAppendingPathExtension:#"themes.json"];
should be:
[docDir stringByAppendingPathComponent:#"themes.json"];
This becomes clear we you read the error message, you see that it tries to write the file to /var/mobile/Applications/ACED3EF9-B0D8-49E8-91DE-37128357E509/Documents.themes.json. Notice that there a . where there should be a /.
The stringByAppendingPathExtension: is used for adding a extension to a file, jpg, txt, html,.....
stringByAppendingPathComponent will add a file to a path, by adding the correct directory separator, you case /.
You second example will definitely fail since the app bundle is readonly.
I try to get my file in my self created Directory in the Documents Directory into a NSData Object like this:
NSString *path = [documentsDirectory stringByAppendingFormat:#"%#%#",#"/",fileName];
NSError* errorr = nil;
NSData *fileData = [NSData dataWithContentsOfFile:path options: 0 error: &errorr];
if (fileData == nil)
{
NSLog(#"Failed to read file, error %#", errorr);
}
else
{
}
But i always get this error:
Failed to read file, error Error Domain=NSCocoaErrorDomain Code=257 "The operation couldn’t be completed. (Cocoa error 257.)" UserInfo=0x156be110 {NSFilePath=/var/mobile/Applications/679253E3-652C-45EE-B589-609E52E4E3B0/Documents/upload/test.xml, NSUnderlyingError=0x156ba7f0 "The operation couldn’t be completed. Permission denied"}
So if i check if the file is readable:
if ([[NSFileManager defaultManager] isReadableFileAtPath: path] == YES)
NSLog (#"File is readable");
else
NSLog (#"File is read only");
i get the result that the file is readable, so why do i get the error if i want to parse that file into NSData?!
UPDATE: i created my file like this:
NSString *filePath = [self dataFilePath:fileName];
[xmlData writeToFile:filePath atomically:YES];
- (NSString *)dataFilePath: (NSString *) path {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [[paths objectAtIndex:0] stringByAppendingPathComponent:#"upload"];
NSError *error = nil;
if (![[NSFileManager defaultManager] fileExistsAtPath:documentsDirectory])
[[NSFileManager defaultManager] createDirectoryAtPath:documentsDirectory withIntermediateDirectories:NO attributes:nil error:&error];
NSString *documentsPath = [documentsDirectory
stringByAppendingPathComponent:path];
return documentsPath;
}
UPDATE2: After creating the file, i move it into another Directory with this function:
- (void)moveXmlFilesToUploadDirectory
{
#try {
//Check if FILES_DIR exists
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [[paths objectAtIndex:0] stringByAppendingPathComponent:FILES_DIR];//filesDir
NSString *uploadDirectory = [[paths objectAtIndex:0] stringByAppendingPathComponent:UPLOAD_DIR];//filesDir
if ([[NSFileManager defaultManager] fileExistsAtPath:documentsDirectory])
{
NSString *extension = #"xml";
NSArray *contents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:NULL];
NSEnumerator *e = [contents objectEnumerator];
NSString *filename;
while ((filename = [e nextObject])) {
if ([[filename pathExtension] isEqualToString:extension]) {
[[NSFileManager defaultManager] moveItemAtPath:documentsDirectory toPath:[uploadDirectory stringByAppendingPathComponent:filename] error:NULL];
}
}
}
}
#catch (NSException *exception) {
}
#finally {
}
}
Maybe the Problem is after moving the file! Cause if i try to get my file into a NSData before i move it, everything works...
It seems that you try to copy the whole directory to a destination meant to be a file. The result is that the filepath is a directory path in the end so you can't open it like a file which leads to the permission error message.
You should update your copy code to
while ((filename = [e nextObject])) {
if ([[filename pathExtension] isEqualToString:extension]) {
[[NSFileManager defaultManager] moveItemAtPath:[documentsDirectory stringByAppendingPathComponent: filename] toPath:[uploadDirectory stringByAppendingPathComponent:filename] error:NULL];
}
}
to copy every file individually. That will create than the actual file at the destination path intend of a directory.
The chances are high that you don't have the right permissions for that file. Please check the permissions and add read access for the current user or "everyone". You can set the read permissions for your user by the info dialog (cmd + i) or in the terminal with chmod u+r test.xml. Eventually you have to set the owner before with
sudo chown yourusername test.xml
Hope that makes sense.
I am trying to copy a file from one folder to another folder in documents directory like this:
- (void)saveFile:(NSString *)folderPath
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"destination.png"];
NSError *error = nil;
NSString *srcPath = [folderPath stringByAppendingPathComponent:#"filename.png"];
BOOL success = [[NSFileManager defaultManager] copyItemAtPath:srcPath toPath:documentsDirectory error:&error];
if (error)
{
NSLog(#"%#",error);
}
if (success == YES)
{
NSLog(#"Copied");
}
else
{
NSLog(#"Not Copied");
}
}
When i log error, it gives me the following message:
Error Domain=NSCocoaErrorDomain Code=516 "The operation couldn’t be completed. (Cocoa error 516.)" UserInfo=0x9d665a0 {NSUserStringVariant=(

), NSFilePath=/Users/username/Library/Application Support/iPhone Simulator/5.1/Applications/BC37C9D7-7995-47C1-8131-2B07BADCBECB/Documents/foldername/B713320C-2CA0-4FD3-93F6-71D76B102B83/src.png, NSDestinationFilePath=/Users/username/Library/Application Support/iPhone Simulator/5.1/Applications/BC37C9D7-7995-47C1-8131-2B07BADCBECB/Documents, NSUnderlyingError=0x9d41c60 "The operation couldn’t be completed. File exists"}
Issue 1:
The issue occurred because, the directory already contains a file with same file name.
You should check whether the file exist in the folder or not like:
- (void)saveFile:(NSString *)folderPath
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"destination.png"];
NSError *error = nil;
NSString *srcPath = [folderPath stringByAppendingPathComponent:#"filename.png"];
if ([[NSFileManager defaultManager] fileExistsAtPath:dataPath])
{
//removing file
if (![[NSFileManager defaultManager] removeItemAtPath:dataPath error:&error])
{
NSLog(#"Could not remove old files. Error:%#",error);
}
}
BOOL success = [[NSFileManager defaultManager] copyItemAtPath:srcPath toPath:dataPath error:&error];
if (success == YES)
{
NSLog(#"Copied");
}
else
{
NSLog(#"Not Copied %#", error);
}
}
Issue 2:
You must provide a file name not a directory.
Replace:
BOOL success = [[NSFileManager defaultManager] copyItemAtPath:srcPath toPath:documentsDirectory error:&error];
With:
BOOL success = [[NSFileManager defaultManager] copyItemAtPath:srcPath toPath:dataPath error:&error];
copyItemAtPath: is giving error as that file is already exist in that location. So you should do this before you copy file.
if ([[NSFileManager defaultManager] fileExistsAtPath: srcPath])
[[NSFileManager defaultManager] removeItemAtPath: srcPath error:nil];
Replace this line:
BOOL success = [[NSFileManager defaultManager] copyItemAtPath:srcPath toPath:documentsDirectory error:&error];
With:
BOOL success = [[NSFileManager defaultManager] copyItemAtPath:srcPath toPath:dataPath error:&error];
