Typhoon inject xib loaded table cells

Question

I'm trying to migrate some of my view controllers and UITableView subclasses over to using Typhoon, but I can't find any documentation around what to do with cells that are generated from a tableView's dequeReusableCellWithIdentifier .

The TableViewController I'm working with uses multiple cell types which it registers with the TableView in viewDidLoad using registerNib:forCellReuseIdentifer: .

What should we do to have Typhoon inject cells loaded from xibs?

Answer 1

Probably the easiest thing to do would be to create a view assembly for your xib loaded table cells, and make this one of your application assemblies. Assuming you're using plist integration then you'd add it to your app's plist as:

<key>TyphoonInitialAssemblies</key>
<array>
    <string>ViewProvider</string>
    <string>ApplicationAssembly</string>
    <string>CoreComponentsAssembly</string>
    <string>NetworkAssembly</string>
</array>

Logically it would sit to the side of your top-level application assembly.

@interface ViewProvider : TyphoonAssembly

//Reference any other assemblies that you need
@property(nonatomic, strong, readonly) CoreComponents *coreComponents;

//Create a definition for the table cell with the injections that need to happen. 
- (UITableViewCell*)myTableViewCell;

Next inject this into your view controller.

@interface MyViewController : UIViewController

@property (nonatomic, strong) InjectedClass(ViewAssembly) viewProvider;

@end 

@implementation MyViewController

- (UITableViewCell *)tableView:(UITableView *)tableView 
    cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    //Load the cell from the XIB first. 
    //And now tell Typhoon to inject it
    [self.viewProvider inject:cell];
    //The above matches by type, you can also provide an @selector() 
    //definition in the assembly

    //Any other config to the cell
    return cell;

}
