Question

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);
    }
}
