is groupTableViewBackgroundColor deprecated on iOS 6?

Question

I was just testing my app with iOS 6.0 and Xcode 4.5GM and I have set up a view like this:

[self.view setBackgroundColor:[UIColor groupTableViewBackgroundCol         


        

Answer 1

I've written a UIColor category to replace groupTableViewBackgroundColor:

@interface UIColor (UITableViewBackground)
+ (UIColor *)groupTableViewBackgroundColor;    
@end

@implementation UIColor (UITableViewBackground)

+ (UIColor *)groupTableViewBackgroundColor
{
    __strong static UIImage* tableViewBackgroundImage = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        UIGraphicsBeginImageContextWithOptions(CGSizeMake(7.f, 1.f), NO, 0.0);
        CGContextRef c = UIGraphicsGetCurrentContext();
        [[self colorWithRed:185/255.f green:192/255.f blue:202/255.f alpha:1.f] setFill];
        CGContextFillRect(c, CGRectMake(0, 0, 4, 1));
        [[self colorWithRed:185/255.f green:193/255.f blue:200/255.f alpha:1.f] setFill];
        CGContextFillRect(c, CGRectMake(4, 0, 1, 1));
        [[self colorWithRed:192/255.f green:200/255.f blue:207/255.f alpha:1.f] setFill];
        CGContextFillRect(c, CGRectMake(5, 0, 2, 1));
        tableViewBackgroundImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
    });
    return [self colorWithPatternImage:tableViewBackgroundImage];
}

@end

This solution also allows to tweak the appearance of the background. Feel free to change the drawing code :)

If it helps anyone, here's specifically what I'm doing in my custom view to get this background (using hint from Mr Beloeuvre)

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor clearColor];
    UITableView *tv = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStyleGrouped];
    [self.view addSubview:tv];
    [self.view sendSubviewToBack:tv];
    // ...
}

Try this:

[myTableView setBackgroundView:nil];
[myTableView setBackgroundView:[[[UIView alloc] init] autorelease]];
