Question

I have a tableview where i return the no of sections and no of rows for each sections dynamically. I can implement it like this

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if(  section == 0)
    return [array count];

    if(  section == 1)
    return [array2 count];

    if(  section == 2)
    return [array3 count];
}

if i am aware that i have 3 sections i can do it in this above mentioned way. But how to dynamically define the no of rows for different sections. e.g:- u have if(section == 0). i dont want to hard code the value of 0,1,2 here. I am not sure about the total no of sections. How can we do it we want to return the no of rows dynamically for different sections? I have an array to display no of sections and different arrays to display no of rows for each section. How to dynamically mention in the method “numberOfRowsInSection”?

Answer 1

here you can follow this approach , you can put all your countable arrays in another NSMutableArray like lets say tmpArray (e.g. tmpArray[0] = array or tmpArray[1] = array2 , or just by appending [tmpArray addObject:array] ..),

then you can go like this

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{
    return [[tmpArray objectAtIndex:section] count];
}

i hope this will help you to solve your problem ..
