Photo bombers - UIRefreshControl, end refreshing

I want to create a pull to refresh for refreshing my collectionView. but when i pull the spinner keeps on going...

in my test method i tried to end refreshing my refresh control, but i get an error that he doesn't know the property 'refreshControl'

In viewDidLoad:

- (void)viewDidLoad {
    [super viewDidLoad];

// Pull to refresh
    UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
    refreshControl.tintColor = [UIColor colorWithRed:242.0 / 255.0 green:122.0 / 255.0 blue:87.0 / 255.0 alpha:1.0];
    [refreshControl addTarget:self action:@selector(test) forControlEvents:UIControlEventValueChanged];
    [self.collectionView addSubview:refreshControl];
    self.collectionView.alwaysBounceVertical = YES;
}

in my test method:

- (void)test {
    NSLog(@"refresh now !!!");
    [self.refreshControl endRefreshing]; // error
}

You can't call self.refreshControl if you don't have a property refreshControl. You are creating this refreshControl object in the viewDidLoad method so you can only manage this object in that method unless you pass it through as a parameter. You need to create it as a property to call self.refreshControl.
