UIRefreshControl iOS 6 xcode

You can just set it up in your viewDidLoad, if you have a UITableViewController:

UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];[refreshControl addTarget:self action:@selector(refresh)         forControlEvents:UIControlEventValueChanged]; self.refreshControl = refreshControl;

Then you can do your refresh stuff here:

-(void)refresh {    // do something here to refresh.}

When you are done with refreshing, call [self.refreshControl endRefreshing]; to stop the refresh control, as pointed out by rjgonzo.

You can also configure this in Interface Builder. Though the way it currently works, it only saves you a couple of lines of code.

Select the TableViewController scene and in the Attributes Inspector, you'll find a drop down list option for "Refreshing." Set that to "Enabled." You'll notice in the View Controller Hierarchy that a "Refresh Control" has been added (you won't see anything visually added to the scene itself). What's odd is that after hooking up the Refresh Control to an IBAction (Value Change Event) the event doesn't seem to get triggered. I'm guessing that's a bug (?) but meanwhile, setting "Refreshing" to enabled creates the UIRefreshControl object and assigns it to the view controller's refreshControl property. With that done, you can add the event handling line to your viewDidLoad method:

[self.refreshControl addTarget:self action:@selector(refreshView:) forControlEvents:UIControlEventValueChanged];

In your refreshView: method, you can do some work and then stop the refresh animation:

- (void)refreshView:(UIRefreshControl *)sender {    // Do something...    [sender endRefreshing];}

Here how you do pull Down and Refresh

In your UITableViewController.h add UIRefreshControl *refreshControl; and -(void) refreshMyTableView; method global declaration

and in viewDidLoad of UITableViewController.m

//initialise the refresh controllerrefreshControl = [[UIRefreshControl alloc] init]; //set the title for pull request    refreshControl.attributedTitle = [[NSAttributedString alloc]initWithString:@"pull to Refresh"];    //call he refresh function    [refreshControl addTarget:self action:@selector(refreshMyTableView)             forControlEvents:UIControlEventValueChanged];    self.refreshControl = refreshControl;

and refresh function with date and time of refresh

-(void)refreshMyTableView{    //set the title while refreshing    refreshControl.attributedTitle = [[NSAttributedString alloc]initWithString:@"Refreshing the TableView"];    //set the date and time of refreshing     NSDateFormatter *formattedDate = [[NSDateFormatter alloc]init];    [formattedDate setDateFormat:@"MMM d, h:mm a"];    NSString *lastupdated = [NSString stringWithFormat:@"Last Updated on %@",[formattedDate stringFromDate:[NSDate date]]];    refreshControl.attributedTitle = [[NSAttributedString alloc]initWithString:lastupdated];    //end the refreshing    [refreshControl endRefreshing];}
