Accessing UITableView cells (iOS)

Overview

Sometimes it is necessary to access UITableView cells by their section and row index. The following code demonstrates how this can be done.

PYTHON:

def main():
    simulator = startApplication("Contacts~iphone")
    waitForApplicationLaunch()

    o = waitForObject("{type='UITableView' visible='1'}")
    c = get_uitableview_cell(o, 0, 0)
    test.log("cell.accessibilityLabel: %s" % c.accessibilityLabel)

def get_uitableview_cell(uitableview_obj, section_index, row_index, verbose=True):
    if verbose:
        test.log("get_uitableview_cell(): Number of sections in UITableView: %s" % uitableview_obj.numberOfSections())
        for section_index in range(uitableview_obj.numberOfSections()):
            section_rows = uitableview_obj.numberOfRowsInSection_(section_index)
            test.log("get_uitableview_cell(): Rows in section #%s: %s" % (section_index, section_rows))
    index_path = NSIndexPath.indexPathForRow_inSection_(row_index, section_index)
    data_source = uitableview_obj.dataSource
    cell = data_source.tableView_cellForRowAtIndexPath_(uitableview_obj, index_path)
    return cell
test.py

Other implementations

JavaScript:

function get_uitableview_cell(uitableview_obj, section_index, row_index, verbose) {
    if (verbose) {
        test.log("get_uitableview_cell(): Number of sections in UITableView: %s" % uitableview_obj.numberOfSections());
        for (section_index in range(uitableview_obj.numberOfSections())) {
            section_rows = uitableview_obj.numberOfRowsInSection_(section_index);
            test.log("get_uitableview_cell(): Rows in section #" + section_index + ": " + section_rows);
        }
    }
    index_path = NSIndexPath.indexPathForRow_inSection_(row_index, section_index);
    data_source = uitableview_obj.dataSource;
    cell = data_source.tableView_cellForRowAtIndexPath_(uitableview_obj, index_path)
    return cell;
}
test.js

Logging UITableView contents

With the above function it is now very easy to log the contents of a UITableView:

function main() {
    // ...

    obj = waitForObject("{type='UITableView' visible='1'}");
    log_uitableview(obj);
}

function get_uitableview_cell(...) {
    ...
}

function log_uitableview(uitableview_obj)
{
    var section_count = uitableview_obj.numberOfSections();
    for (var section_index = 0; section_index < section_count; section_index++) {
        section_row_count = uitableview_obj.numberOfRowsInSection_(section_index);
        test.log("Rows in section " + section_index + ": " + section_row_count);
        for (var row_index = 0; row_index < section_row_count; row_index++) {
            cell = get_uitableview_cell(uitableview_obj, section_index, row_index);
            test.log("Cell at section " + section_index + ", row " + row_index + ": " + cell.text, cell);
        }
    }
}
test.js
