iOS Tutorial => Objective-C Example

Example

First declare a property like this in the ViewController

@property (nonatomic) UIRefreshControl *refreshControl;

Later in the viewDidLoad() set up the refreshControl as given below:

self.refreshControl = [[UIRefreshControl alloc]init];
[self.tableView addSubview:self.refreshControl];
[self.refreshControl addTarget:self action:@selector(refreshTable) forControlEvents:UIControlEventValueChanged];
//Setting the tint Color of the Activity Animation
self.refreshControl.tintColor = [UIColor redColor];
//Setting the attributed String to the text
NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@"firstsecondthird"];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,5)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(5,6)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(11,5)];
self.refreshControl.attributedTitle = string;

Now The function refreshTable is defined as:

- (void)refreshTable {
    //TODO: refresh your data
    [self.refreshControl endRefreshing];
    [self.refreshControl beginRefreshing];
    [self.tableView reloadData];
    [self.refreshControl endRefreshing];
}
