Question

I have 2 questions.

1.) I have a tableView, and it will have more than 100 rows (of data). But i will only display 10 records at a time. when the user scrolls down and below the 10th row i want to add a button, which says load the next 10 records and load the previous 10 records. How do i add these buttons ? note: that these buttons only appear when you scroll down to the last record of your table view (I found a similar example in iTunes too)

2.) I need those 2 buttons to have an arrow shape (As a Navigation button)

How do i get this done programatically. (I will not be using the interface builder to create this)

Answer 1

Use these steps and code.

1) create Button

2) Background Image for the UIButton

3) Add target (getNext10List)

4) Create footer view

5) Add the view in your cell.

    UIButton *pagingButton = [UIButton buttonWithType:UIButtonTypeCustom];
    pagingButton.frame = CGRectMake(0, 5, 316, 35);
    pagingButton.backgroundColor = [UIColor clearColor];
    UIImage *buttonImageNormal = [UIImage imageNamed:@"[e-mail]"];
    [pagingButton setBackgroundImage:buttonImageNormal forState:UIControlStateNormal];
    [pagingButton addTarget:self action:@selector(getNext10List) forControlEvents:UIControlEventTouchUpInside];

    //create a footer view on the bottom of the tabeview
    footerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 316, 45)];
    [footerView addSubview:pagingButton];

    messageTableView.tableFooterView = footerView;     
    [[self view] addSubview:messageTableView];
