UIRefreshControl without UITableViewController
Just curious, as it doesn't immediately seem possible, but is there a sneaky way to leverage the new iOS 6 UIRefreshControl
class without using a UITableViewController
subclass?
I often use a UIViewController
with a UITableView
subview and conform to UITableViewDataSource
and UITableViewDelegate
rather than using a UITableViewController
outright.
On a hunch, and based on DrummerB's inspiration, I tried simply adding a UIRefreshControl
instance as a subview to my UITableView
. And it magically just works!
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
[refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged];
[self.myTableView addSubview:refreshControl];
This adds a UIRefreshControl
above your table view and works as expected without having to use a UITableViewController
:)
EDIT: This above still works but as a few have pointed out, there is a slight "stutter" when adding the UIRefreshControl in this manner. A solution to that is to instantiate a UITableViewController, and then setting your UIRefreshControl and UITableView to that, i.e.:
UITableViewController *tableViewController = [[UITableViewController alloc] init];
tableViewController.tableView = self.myTableView;
self.refreshControl = [[UIRefreshControl alloc] init];
[self.refreshControl addTarget:self action:@selector(getConnections) forControlEvents:UIControlEventValueChanged];
tableViewController.refreshControl = self.refreshControl;
To eliminate the stutter that is caused by the accepted answer, you can assign your UITableView
to a UITableViewController
.
_tableViewController = [[UITableViewController alloc]initWithStyle:UITableViewStylePlain];
[self addChildViewController:_tableViewController];
_tableViewController.refreshControl = [UIRefreshControl new];
[_tableViewController.refreshControl addTarget:self action:@selector(loadStream) forControlEvents:UIControlEventValueChanged];
_theTableView = _tableViewController.tableView;
EDIT:
A way to add a UIRefreshControl
with no UITableViewController
with no stutter and retain the nice animation after refreshing data on the tableview.
UIRefreshControl *refreshControl = [UIRefreshControl new];
[refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged];
[self.theTableView addSubview:refreshControl];
[self.theTableView sendSubviewToBack:refreshControl];
Later when handling the refreshed data...
- (void)handleRefresh:(UIRefreshControl *)refreshControl {
[self.theTableView reloadData];
[self.theTableView layoutIfNeeded];
[refreshControl endRefreshing];
}
What you would try is use container view inside ViewController you are using. you can define clean UITableViewController subclass with dedicated tableview and place that in the ViewController.
