Is there anyway to get the rows count of current tableView?

Not visibleCells, the total rows count.

I know there is a datasource array, but is it possible to obtain without concerning data?

Somebody said this question statement is unclear, so update my situation: I want to insert some rows into tableView, one common way is reassemble the datasource array then use [tableView reloadData] to refresh whole tableView, but I don't wanna do this because of user experiments. Instead I try to use insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation method to just insert the new rows, so one must-do thing is to create the indexPaths. I choose [NSIndexPath indexPathWithIndex:], so you know I should get the previous number of rows then generate indexPaths array and before invoking insertRowsAtindexPaths:withRowAnimation: update the datasource array. It is important for opportunity to update the datasource array by this way. It sucks i think, so I'm a little curious "Is there anyway to get the rows count of current tableView?"

In swift 3:

func getAllRowCount()->Int{
    var rowCount = 0
    for index in 0...self.tableView.numberOfSections-1{
        rowCount += self.tableView.numberOfRows(inSection: index)
    }
    return rowCount
}

To get the total number of rows in your table view, loop through each section in the table view and increment the rowCount by the number of rows in the current section:

NSInteger rowCount = 0;

for (NSInteger i = 0 ; i < tableView.numberOfSections ; i ++) {
    rowCount += [tableView numberOfRowsInSection:i];
}

Simply use [TableView numberOfRowsInSection:yourSection];

If all your table rows have the same height, then you probably can go:

row count = tableView.contentSize.height / tableView.rowHeight

But if you're tableView has different row heights, I can't help you :D
