Question

I have a TableView with 10 sections that are loaded from a plist file and I have switches with which some of the sections can be turned off. I need to set a specific background color for each section with the fact that the section can be disabled.

Example:

for section Black I need to set black background

for section Red I need to set red background

and so on…

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UIView *tempHeaderView=[[UIView alloc]initWithFrame:CGRectMake(0,0,320,44)];
     tempHeaderView.backgroundColor=[UIColor blackColor];

     [tempHeaderView addSubView: tempHeaderLabel];
     return tempHeaderView;
}

Answer 1

Keep an NSArray of UIColor objects as an instance variable of your class (the view controller that acts as delegate/data source), say you call it sectionColors. You can initialize the colors in this array from values in your plist, or hard-code the colors.

Then, use this code:

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UIView *tempHeaderView=[[UIView alloc]initWithFrame:CGRectMake(0,0,320,44)];


    // This changed:
    tempHeaderView.backgroundColor = [sectionColors objectAtIndex:section];

    [tempHeaderView addSubView: tempHeaderLabel];

    return tempHeaderView;
    // Use 'return [tempHeaderView autorelease];' in a non-ARC environment
}

This is how you could initialize the array:

// Assuming your table has three sections (indices 0 through 2)

UIColor* colorForSection0 = [UIColor colorwithRed:redValue0 green:greenValue0 blue:blueValue0 alpha:1.0];
// redValue0, etc. are floats between 0.0 and 1.0 that you can read from a .plist
// Alternatively, store them as integers between 0 and 255, and divide them by 255.0 
// and store on CGFloat variables before creating color.

// ...Do the same for the other colors...

// Now that you have the colors, create array and store in ivar 'sectionColors'
sectionColors = [[NSArray alloc] initWithObjects: 
    ColorforSection0, ColorForSection1, colorForSection2, nil];

(the code above should go inside the table view data source’s initializer)
