EPSReactiveTableViewController is a subclass of UITableViewController that automatically populates a table view, and animates the insertion and deletion of rows by observing changes to an array of model objects. It uses ReactiveCocoa, and is designed to be used with the MVVM pattern.
EPSReactiveCollectionViewController provides similar functionality for collection view controllers.
Subclass EPSReactiveTableViewController, and write an init method which calls initWithStyle:bindingToKeyPath:onObject: on super to set up the binding. The value at the key path must always be an NSArray containing objects that implement -isEqual: and -hash. No object should appear in the array more than once. In the init method, register a cell class for use with the class of object that will be contained in the observed array. (The cell class must conform to <EPSReactiveTableViewCell>.)
- (id)init {
EPSExampleViewModel *viewModel = [EPSExampleViewModel new];
self = [super initWithStyle:UITableViewStylePlain bindingToKeyPath:@"sortedObjects" onObject:viewModel];
[self registerCellClass:[EPSNoteCell class] forObjectsWithClass:[EPSNote class]];
...
return self;
}If you want to know when a cell is tapped on, subscribe to the didSelectRowSignal property.
[self.didSelectRowSignal subscribeNext:^(RACTuple *tuple) {
RACTupleUnpack(id object, NSIndexPath *indexPath, UITableView *tableView) = tuple;
// Do something with `object`
}];You don’t need to write any <UITableViewDataSource> methods.
