Simple editing the tags

[ghostiam]

1. Enable always the delete button:
   • open file AKTagCell.m
   • delete _deleteButton.enabled = selected; from -(void)setSelected:(BOOL)selected
   • replace _deleteButton.enabled = NO; on _deleteButton.enabled = YES; from -(UIButton *)deleteButton
2. Add next code to the file AKTagsInputView.m

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath{
    UIAlertView *alertViewChangeTag = [[UIAlertView alloc] init];
    [alertViewChangeTag setDelegate:self];
    [alertViewChangeTag setTitle:@"Edit tag"];
    [alertViewChangeTag addButtonWithTitle:@"Cancel"];
    [alertViewChangeTag addButtonWithTitle:@"OK"];
    [alertViewChangeTag setAlertViewStyle:UIAlertViewStylePlainTextInput];

    AKTagCell* cell = (AKTagCell*)[collectionView cellForItemAtIndexPath:indexPath];
    [[alertViewChangeTag textFieldAtIndex:0] setText:cell.tagName];
    [[alertViewChangeTag textFieldAtIndex:0] setDelegate:self];
    [alertViewChangeTag show];
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    NSString *newTag = [[alertView textFieldAtIndex:0] text];

    if (buttonIndex == 1 && newTag.length > 0) {
        NSIndexPath* index = [self.collectionView indexPathsForSelectedItems][0];
        [self deleteItemAt:index completion:nil];
        [self addNewItemWithString:newTag completion:nil];
    }
}

Maybe someone deems useful.
