Question

I’m trying to create a custom view for my UITableView footerView that has a button in it. I can see it there, but when I touch it, nothing happens… can you see what’s wrong here:

- (void)viewDidLoad {
    [super viewDidLoad];

    if(self.tableView.tableFooterView == nil) {
        //allocate the view if it doesn't exist yet
        UIView *footerView  = [[UIView alloc] init];

        //create the button
        UIButton *addNewBtn = [UIButton buttonWithType:UIButtonTypeCustom];     
        //the button should be as big as a table view cell
        [addNewBtn setFrame:CGRectMake(0, 0, 320, [AddMerchantTVC cellHeight])];

        //set title, font size and font color
        [addNewBtn setTitle:@"Add New" forState:UIControlStateNormal];
        [addNewBtn.titleLabel setFont:[UIFont boldSystemFontOfSize:20]];
        [addNewBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        [addNewBtn addTarget:self action:@selector(addNew:) forControlEvents:UIControlEventTouchUpInside];

        UIImageView *cellGradient = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cellGradient.png"]];
        cellGradient.frame = CGRectMake(0, 54, 320, 16);
        [footerView addSubview:cellGradient];

        //add the button to the view
        [footerView addSubview:addNewBtn];
        footerView.userInteractionEnabled = YES;
        self.tableView.tableFooterView = footerView;
        self.tableView.tableFooterView.userInteractionEnabled = YES;

        [footerView release];
        [cellGradient release];
}

- (void)addNew:(id)sender {
    // This is never called
    NSLog(@"Touched.");
}

You’re not setting the footerView’s frame. Set the frame of the footerView to be at least as high as the button otherwise the touches don’t get passed down to the button.
