Renaming and moving file using NSFIleManager - iphone

Question

This is my code to rename and move file from a temporary directory to My Documents directory.
So the problem is within two sections of mode Create a Directory and Attempt to move. The rest all is working correctly..
When I comment out the Create directory section, the Attempt to Move section logs in the console:
Unable to Move the File..Error Code 4.
Now I researched error code 4 and it means that the directory does not exist. So I added the code to create the directory.
Now when I run the program the directory is created but the Attempt to Move section logs:
Unable to Move File..error code 512
Now researching on it it is due to the file already exists. The destination must not exist.
So I am pretty confused, since both error codes are contracting each other.
{
NSError *error;
NSFileManager* manager = [[NSFileManager alloc] init];
NSString* tempFile =[NSTemporaryDirectory() stringByAppendingPathComponent:#"recordTest.caf"];
if (tempFile)
{
// Get the Documents Directory
NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents"];
NSLog(#"Documents directory: %#",
[manager contentsOfDirectoryAtPath:documentsDirectory error:&error]);
//Get the User File Save Name from the text field
NSString *UserText = [[self FileNameText] text];
// Rename the file, by moving the file
NSString *filePath2 = [documentsDirectory
stringByAppendingPathComponent:[NSString stringWithString:UserText]];
// Create a Directory
if( [manager createDirectoryAtPath:[NSString stringWithFormat:#"%#/%#",documentsDirectory,UserText] withIntermediateDirectories:NO attributes:nil error:&error]!= YES)
{
NSLog(#"Directory error");
}
if([manager fileExistsAtPath:[NSString stringWithFormat:#"%#/%#",documentsDirectory,UserText]])
{
NSLog(#"Path exist");
NSLog(#"Documents directory: %#",
[manager contentsOfDirectoryAtPath:documentsDirectory error:&error]);
}
// Attempt the move
if ([manager moveItemAtPath:tempFile toPath:filePath2 error:&error] != YES)
{
NSLog(#"Unable to move file: %#", [error localizedDescription]);
}
else
{
if ([manager removeItemAtPath:tempFile error:&error] != YES)
NSLog(#"Unable to delete file: %#", [error localizedDescription]);
}
}
[manager release];
}

Answer 1

The problem is most likely that the file you are trying to move doesn't exist.
replace
if (tempFile) //this will return YES every time, telling you you have a string!
with
if ([manager fileExistsAtPath:tempFile]) //this will tell you if the file exists at that path
A few notes
1. To see with your eyes if the file you are looking for really exists, check the simulator application folders at something similar to this:
/Users/yogevshelly/Library/Application\ Support/iPhone\
Simulator/5.0/Applications
then browse to a specific application
2. Don't just append strings to get folders , do something like this:
NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [dirPaths objectAtIndex:0];
3. The following line will create a folder with the file's name as the folders name!:
[manager createDirectoryAtPath:filePath2 withIntermediateDirectories:NO attributes:nil error:&error]
creating a folder from a filename seems weird, what you want to do is either copy the file to an existing directory or first create a directory and copy the file into-it

Answer 2

you use the metod
contentsOfDirectoryAtPath: withIntermediateDirectories: attributes:error
this method create directory but you pass it the filename.
i think you create /Documents/filename/ instead of /Documents/filename

Answer 3

As per my understanding the problem part of the code is following one
// Create a Directory
if( [manager createDirectoryAtPath:[NSString stringWithFormat:#"%#/%#",documentsDirectory,UserText] withIntermediateDirectories:NO attributes:nil error:&error]!= YES)
{
NSLog(#"Directory error");
}
You are creating a folder in with the file name in same location .... try commenting the the above code .. it should work.
