UIRefreshControl is in wrong position in UITableViewController

Question

I\'ve seen quite a few problems with UIRefreshControl, and I\'m having a problem as well with my UITableViewController. The problem occurs so randomly and henceforth I cannot fi

Answer 1

This is a known bug with iOS7; sometimes the refresh control is put incorrectly in the front of the view hierarchy instead of back. You can counter part of the problem by sending it to back after layout:

- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];

    [self.refreshControl.superview sendSubviewToBack:self.refreshControl];
}

Animation will still be imperfect, but at least it will still be below the table view. Please open a bug report with Apple for this issue.

Also, as stated in another answer, you should not add the refresh control to the view hierarchy yourself. The table view controller will do that for you. But that is not the issue here.

Swift version

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    refreshControl?.superview?.sendSubview(toBack: refreshControl!)
}
