UIRefreshControl is not working in collection view

I have added a UIRefreshControl to my collection view:

 self.refreshControl = [[UIRefreshControl alloc]init];
[self.refreshControl addTarget:self action:@selector(refreshCV:) forControlEvents:UIControlEventValueChanged];
[self.collectionView addSubview:self.refreshControl]; 

- (void)refreshCV:(UIRefreshControl *)refresh{ 
      NSLog(@"Refresh");
      [refresh endRefreshing];
}

But it is not working always. In other words, sometimes when pulling down it is doesn't call the refresh function. How to solve this?

Try this answer. You have to set alwaysBounceVertical property of collection view.

#pragma mark UIRefreshControl

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

    //add UIRefreshControl to Collection view
    [self.collectionView addSubview:refreshControl];
}

- (void)refresh:(id)sender 
{
    UIRefreshControl *refreshControl = (UIRefreshControl *)sender;

    // End the refreshing
    if (refreshControl) {
        [refreshControl endRefreshing];
    }

}

Here is an example of a UIRefreshControl.

UIRefreshControl *control = [[UIRefreshControl alloc] initWithFrame:CGRectZero];
control.tintColor = someColor;
[control sizeToFit];
[tableView addSubview:control];

You add refreshCV as the target function for refresh control while you actually have refreshTV below. Please check to make sure which function you want indeed.

If you are not using UITableViewController class, then do as below

UITableViewController *tableViewController = [[UITableViewController alloc] init];
tableViewController.tableView = self.myTableView;
self.refreshControl = [[UIRefreshControl alloc] init];
[self.refreshControl addTarget:self action:@selector(refreshTV:) forControlEvents:UIControlEventValueChanged];
tableViewController.refreshControl = self.refreshControl;

- (void)refreshTV:(UIRefreshControl *)refresh{ 
      NSLog(@"Refresh");
      [refresh endRefreshing];
}
