Tutorial

The patch is a zip file contains patch.lua and other lua codes. The sample code can be found at /patch folder.

The sample iOS project loads the patch from a url (which you probably want to change in AppDelegate.m) before launch.

The original version in obj-c:

@implementation MainViewController

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return 10;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"Cell"];
    cell.textLabel.text = [NSString stringWithFormat:@"%d", indexPath.row + 1];
    return cell;
}

@end

The pacthed version with lua:

waxClass{"MainViewController", UITableViewController}

function tableView_cellForRowAtIndexPath(self, tableView, indexPath)
	local cell = self:ORIGtableView_cellForRowAtIndexPath(tableView, indexPath) -- The original method is retained with 'ORIG' prefix
	cell:textLabel():setText("" .. (10 - indexPath:row()))
	cell:detailTextLabel():setText("http://github.com/mmin18")
	cell:textLabel():setTextColor(UIColor:redColor())
	return cell
end
