Question

im working on application that have search view, the search view contain a tableView with 3 sections - i implement the section manually by

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{
    // Return the number of sections.
    return 3;
}


- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{

    if (section == 0){
        UITextField *title = [[UITextField alloc]initWithFrame:CGRectMake(0, 0, 320, 10)];
        [title setBackgroundColor:[UIColor lightGrayColor]];
        [title setTextAlignment:UITextAlignmentRight];
        [title setFont:[UIFont boldSystemFontOfSize:15]];
        [title setText:@"videos"];
        return title ;
    }
    if (section == 1){
        UITextField *title = [[UITextField alloc]initWithFrame:CGRectMake(0, 0, 320, 10)];
        [title setBackgroundColor:[UIColor lightGrayColor]];
        [title setTextAlignment:UITextAlignmentRight];
        [title setFont:[UIFont boldSystemFontOfSize:15]];
        [title setText:@"documents"];
        return title ; 
    }
    if (section == 2){
        UITextField *title = [[UITextField alloc]initWithFrame:CGRectMake(0, 0, 320, 10)];
        [title setBackgroundColor:[UIColor lightGrayColor]];
        [title setTextAlignment:UITextAlignmentRight];
        [title setFont:[UIFont boldSystemFontOfSize:15]];

as you can see- i have title with the names of the sections, but how should i determine the correct sections for the cells ? im parsing all the data to one array and then getting it out using dictionary:

NSDictionary *object = [ResultsArrayDisplay objectAtIndex:indexPath.row];

please help me, im after few hours of tries with nothing helpful in the internet so far.

This is your problem:

im parsing all the data to one array and then getting it out using dictionary:

Put the data for each section in its own array then use indexPath.section to determine which array to use. For each section it will give you rows for that section only so you can use the indexPath.row to index into each of your arrays.

If you insist on keeping everything in one array, then you will have to maintain a count of how many of each type you have and then use that to figure out which array index you need.

In either case be sure to implement numberOfRowsinSection:. If you're using multiple arrays then this will just be the array count for that section otherwise it will be the portion of your main array that is used in that section.

ok, im working on it.. i will let you know if i need any help. TNX — Amir Foghel, May 29 '12 at 18:01
