Get current indexPath row with multiple sections?

first you do not need the first if because it would not run through the for-next. Then you are adding one which is not necessary and then you can just add the indexPath.row like that:

    NSInteger sumSections = 0;
    for (int i = 0; i < indexPath.section; i++) {
        int rowsInSection = [activitiesTable numberOfRowsInSection:i];
        sumSections += rowsInSection;
    }
    currentRow = sumSections + indexPath.row;
