refresh controller for embedded tableview ios 6

Question

Hi i currently have embedded tableview in UIViewController. In the tableview i have collection of json data. I wish to make a refresh controller, so whenever the user pulls down, the json data is refreshed.

I have tried the following code

- (void)viewDidLoad
{
[superviewDidLoad];

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

}

-(void) updateArray{
[self.tableView reloadData];
[self.refreshControl endRefreshing];
}

I am getting an error which says property refreshControl not found in ViewController.

Is it because i am using embedded tableview or am i doing something wrong?

Answer 1

You are instantiating the UIRefreshControl inside the viewDidLoad method. The reference to that object is not visible to the updateArray method. You will need to either make it a property or a instance variable.

@property (strong, nonatomic) UIRefreshControl *refreshControl;

then instead of

UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];

use

refreshControl = [[UIRefreshControl alloc] init];
