Question

I m a total beginner in iOS development and need a bit of help:

I have a UIViewController with 2 nested TableViews.
(Implementation like here)

.h file

#import <UIKit/UIKit.h>

@interface TabAboutViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> {
}

    @property (nonatomic, strong) NSArray *navigationList;

@end

.m file

#import "TabAboutViewController.h"

@interface TabAboutViewController ()

@end

@implementation TabAboutViewController

#pragma mark -
#pragma mark Synthesize

@synthesize navigationList;
@synthesize informationTableView;

#pragma mark -
#pragma mark View Load

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    navigationList = [NSArray arrayWithObjects:@"Was leistet die App?",@"Wie wird gemessen?",@"Wie wird ausgewertet?",@"Was sind die Vorteile?",nil];
}

#pragma mark -
#pragma mark View UnLoad

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.

}

#pragma mark -
#pragma mark View Rotates

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

#pragma mark -
#pragma mark Table Management

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Return the number of rows in the section.
    return [self.navigationList count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"aboutCell"];
    NSString *cellText = [self.navigationList objectAtIndex:indexPath.row];
    cell.textLabel.text = cellText;

    return cell;
}

@end

Now i want to set the background Color for one of the TableViews in the UIViewController, but i dont know how and where to do it. i dont want to change it in the storyboard.

Answer 1

You can do that in -viewDidLoad:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.myTableView.backgroundColor = [UIColor red];
    // ...
}

And don’t forget to add an IBOutlet to the table view in the .h file if you didn’t already do that and link to it from Interface Builder:

@property (weak, nonatomic) IBOutlet UITableView *myTableView;

If you use tags to identify your views, you can do something like this:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    UITableView *myTableView = [self.view viewWithTag:1]; // Or what ever tag you associate with the table view
    myTableView.backgroundColor = [UIColor red];
    // ...
}
