How to rename some files programmatically ?

Answer 1

try this code :

NSError * err = NULL;
NSFileManager * fm = [[NSFileManager alloc] init];
BOOL result = [fm moveItemAtPath:@"/tmp/test.tt" toPath:@"/tmp/dstpath.tt" error:&err];
if(!result)
    NSLog(@"Error: %@", err);

other wise use this method to rename file

- (void)renameFileWithName:(NSString *)srcName toName:(NSString *)dstName
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *filePathSrc = [documentsDirectory stringByAppendingPathComponent:srcName];
    NSString *filePathDst = [documentsDirectory stringByAppendingPathComponent:dstName];
    NSFileManager *manager = [NSFileManager defaultManager];
    if ([manager fileExistsAtPath:filePathSrc]) {
        NSError *error = nil;
        [manager moveItemAtPath:filePathSrc toPath:filePathDst error:&error];
        if (error) {
            NSLog(@"There is an Error: %@", error);
        }
    } else {
        NSLog(@"File %@ doesn't exists", srcName);
    }
}

There is no Direct API to rename the file . Though when you move the file from one place to another place, if that file in destination path not exists then iOS will create the file in the given name. For file you can just give the New name of your file, how it should be displayed/referenced.
