Extension to UITableViewController in attempt to provide additional features that are reusable in most scenarios.
Configure the loading style, currently support header and footer.
- (void)viewDidLoad
{
[super viewDidLoad];
theTableViewController.loadingStyle = MwfTableViewLoadingStyleFooter; // default is MwfTableViewLoadingStyleHeader
}
Programmatically trigger loading animation
[theTableViewController setLoading:YES animated:YES];
Programmatically stop loading animation
[theTableViewController setLoading:YES animated:NO];
If you need to, you can override few methods to provide custom look and feel for your app.
- (UIView *)createLoadingView
{
// ... construct your custom loading view
return yourAwesomeCustomLoadingView;
}
- (void)willShowLoadingView:(UIView *)loadingView
{
// cast to your implementation
YourAwesomeLoadingView * view = (YourAwesomeLoadingView *)loadingView;
// ... do something about it, e.g. start animating the activity indicator view
}
- (void)didHideLoadingView:(UIView *)loadingView
{
// cast to your implementation
YourAwesomeLoadingView * view = (YourAwesomeLoadingView *)loadingView;
// ... do something about it, e.g. stop animating the activity indicator view
}
A class MwfTableData
is provided to manage your table backing store.
Instead of using NSArray
, this class provides all the convenience you need working with table view.
Creating Table Data
+ (MwfTableData *) createTableData;
+ (MwfTableData *) createTableDataWithSections;
Accessing data
- (NSUInteger) numberOfSections;
- (NSUInteger) numberOfRowsInSection:(NSUInteger)section;
- (NSUInteger) numberOfRows;
- (id) objectForSectionAtIndex:(NSUInteger)section;
- (id) objectForRowAtIndexPath:(NSIndexPath *)ip;
- (NSIndexPath *) indexPathForRow:(id)object;
- (NSUInteger) indexForSection:(id)sectionObject;
Inserting data
- (NSUInteger)addSection:(id)sectionObject;
- (NSUInteger)insertSection:(id)sectionObject atIndex:(NSUInteger)sectionIndex;
- (NSIndexPath *)addRow:(id)object inSection:(NSUInteger)sectionIndex;
- (NSIndexPath *)insertRow:(id)object atIndexPath:(NSIndexPath *)indexPath;
- (NSIndexPath *)addRow:(id)object;
- (NSIndexPath *)insertRow:(id)object atIndex:(NSUInteger)index;
Deleting data
- (NSIndexPath *)removeRowAtIndexPath:(NSIndexPath *)indexPath;
- (NSUInteger)removeSectionAtIndex:(NSUInteger)sectionIndex;
Updating data
- (NSUInteger)updateSection:(id)object atIndex:(NSUInteger)section;
- (NSIndexPath *)updateRow:(id)object atIndexPath:(NSIndexPath *)indexPath;
Override createAndInitTableData
In this method, you can create MwfTableData
instance using one of the creation methods (with or without section) and initialize with some data.
- (MwfTableData *)createAndInitTableData;
{
MwfTableData * tableData = [MwfTableData createTableData];
[tableData addRow:@"Row 1"];
[tableData addRow:@"Row 2"];
[tableData addRow:@"Row 3"];
[tableData addRow:@"Load More"];
return tableData;
}
Performing bulk updates
MwfTableViewController
provides method performUpdates:(void(^)(MwfTableData *))updatesBlock
which you can call to perform bulk updates to your table view (add,remove,update sections/rows). This method will update the backing store as well as updating the table view (using UITableViewRowAnimationAutomatic
for row animation). This method frees you from tracking the changed index sets and paths, and lets you focus on the application logic that updates your table.
- (void)loadMoreData {
[self performUpdates:^(MwfTableData * data) {
// ... call the insert/delete/update method of MwfTableData
}];
}
Reload table view
Setting table data via tableData
property of MwfTableViewController
will trigger tableView's reloadData
.
- (void)reloadEntireTable { // a method in your MwfTableViewController subclass
MwfTableData * tableData = [MwfTableData createTableDataWithSections];
[tableData addSection:@"Section 1"];
[tableData addRow:@"Row 1" inSection:0];
[tableData addRow:@"Row 2" inSection:0];
self.tableData = tableData;
}
