NSFileManager: Copy file not success - iphone

Question

I want to copy files located at /Library to the folder /User/Library/AddressBook/Sample/,
I used:
[[NSFileManager defaultManager] copyItemAtPath: #"/Library/MyFile.mp3"
toPath: #"/User/Library/AddressBook/Sample/MyFile.mp3"
error: &error];
But I encountered an error that says `Operation could not be completed. No such file or
directory`
I am working on a jailbroken iPhone.

Answer 1

The directory:
/User/Library/AddressBook/Sample/
does not exist on a phone normally. Have you added the Sample subdirectory, before trying to copy the mp3 file into it?
With the NSFileManager methods, I would also recommend using the error object to help you debug:
NSError* error;
[[NSFileManager defaultManager] copyItemAtPath:#"/Library//MyFile.mp3" toPath: #"/User/Library/AddressBook/Sample/MyFile.mp3" error:&error];
if (error != nil) {
NSLog(#"Error message is %#", [error localizedDescription]);
}
Also, it looks like there is a mistake in your spelling of copyItemAtPath, but probably it's only in your question, and not in your code? Anyway, please double-check.
And, you have a double-slash (//) in your path, too, but I don't think that's hurting you. Just take it out, and be careful when typing :)
Update
If you are just running this app normally, but on a jailbroken phone, your app won't have access to those directories. Apps installed normally, on a jailbroken phone, still are sandboxed. The jailbreak doesn't remove all the rules on the phone. If you install the app in /Applications, like true jailbreak apps are, then that code should work for you.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *libraryDirectory = [paths objectAtIndex:0];
NSLog(#"%#",libraryDirectory); // Library path
NSString *AddressBookPath = [libraryDirectory stringByAppendingPathComponent:#"AddressBook"];
if (![[NSFileManager defaultManager] fileExistsAtPath:AddressBookPath])
{
NSError* error;
// Create "AddressBook Dir"
if([[NSFileManager defaultManager] createDirectoryAtPath:AddressBookPath withIntermediateDirectories:NO attributes:nil error:&error])
{
// Create "Sample Dir"
NSString *samplePath = [AddressBookPath stringByAppendingPathComponent:#"Sample"];
if (![[NSFileManager defaultManager] fileExistsAtPath:AddressBookPath])
{
NSError* error;
if([[NSFileManager defaultManager] createDirectoryAtPath:AddressBookPath withIntermediateDirectories:NO attributes:nil error:&error])
{
// Copy Files Now
NSError* error;
NSString *fromPath = [libraryDirectory stringByAppendingPathComponent:#"MyFile.mp3"];
NSString *toPath = [samplePath stringByAppendingPathComponent:#"MyFile.mp3"];
[[NSFileManager defaultManager] copyItemAtPath:fromPath toPath:toPath error:&error];
if (error != nil)
{
NSLog(#"Error message is %#", [error localizedDescription]);
}
}
}
}
else
{
NSLog(#"[%#] ERROR: attempting to write create MyFolder directory", [self class]);
NSAssert( FALSE, #"Failed to create directory maybe out of disk space?");
}
}
