ios – 使用UIViewControler和UITableView在UITabBarController中切换选项卡后,UIRefreshControl卡住了

我已经尝试了所有建议的解决方案HERE,但没有一个适合我.

以下是我正在做的事情.

- (void)viewDidLoad {
[super viewDidLoad];

data = [[NSMutableArray alloc] initWithArray:[[DataCache sharedCache] getData]];

[self addNavBar];
[self addDataTable];

//for refreshing the table data
UITableViewController *tableViewController = [[UITableViewController alloc] init];
tableViewController.tableView = dataTable;
refreshControl = [[UIrefreshControl alloc] init];
refreshControl.BACkgroundColor = [UIColor purpleColor];
refreshControl.TintColor = [UIColor whiteColor];
[refreshControl addTarget:self
                   action:@SELEctor(refresh)
         forControlEvents:UIControlEventValueChanged];
[dataTable addSubview:refreshControl];
tableViewController.refreshControl = refreshControl;
}


- (void)refresh {
[self loadSentData];
data = [[NSMutableArray alloc] initWithArray:[[DataCache sharedCache] getSentData]];
[self performSELEctorOnMainThread:@SELEctor(reloadData) withObject:nil waitUntilDone:NO];
}

- (void)reloadData{
[dataTable reloadData];
[refreshControl endrefreshing];
}
