very strange behavior with UITableView

Question

I have a simple tableView where the value in numberOfRowsInSection depends on the type of data I am displaying, ie, names or details, etc..

The table is first loaded with certain details where the row count is 6. I added an NSLog statement and indeed I am returning 6 rows.

I also have to set the row height and again, my log statements says it is being called 6 times. great. My problem is cellForRowAtIndexPath is only called 5 times. it's missing the last call.

Note: I have a toolBar that reloads the table with different options. When I select a new option then go back, the table populates properly. It has 6 rows as it should have. Everything is connected properly: delegate, datasource and outlet as proven by the fact that the table is being partially loaded. Does anyone have any idea why this is happening or how to fix it?

如果最后一个单元格在屏幕上不可见，那么如果不滚动并使该单元格可见，则将不会调用cellForRowAtIndexPath方法。
