Total number of rows in UITableView with multiple sections

Question

I need to calculate the total number of rows in my UITableView, however I have multiple sections. Is there a property on the table view I can access? If not, how can I find this information?

Answer 1

Create an "Objective-c Category" of UITableView from the new file dialogue of xCode and add this method to it:

-(NSInteger)numberOfRowsInTotal{
    NSInteger sections = self.numberOfSections;
    NSInteger cellCount = 0;
    for (NSInteger i = 0; i < sections; i++) {
        cellCount += [self numberOfRowsInSection:i];
    }

    return cellCount;
}

Then import your category header into any class that you need to access this method in et voila, you have what you're looking for.

Answer 2

You can easily calculate this value by iterating through each section.

NSUInteger allRows = 0;
for(NSInteger i = 0; i < [tableview numberOfSections]; i++)
{
        allRows += [tableview numberOfRowsInSection:i];
}

If you would like a property you can easily add the above code to a category for UITableView.
