ReloadData doesn't fire tableView:numberOfRowsInSection:

Question

I just encouter a problem, that I call UITableView reloadData method, but nothing happened. No tableView:numberOfRowsInSection is called.

The scenario is:

Table works fine in view A (has the UITableView), then view B shows and hide, after this step, the UITableView reloadData is not working anymore. I am sure reloadData is called in main UI thread and the data source has been changed. Also NO IBOutlet connection issue.

Answer 1

尝试将对reloadData的调用放在viewWillAppear中。

Answer 2

Set BreakPoint on [tableView reloadData]; check that your tableView object is not nil.
