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
