Question

I’m trying to add UIScrollView with paging as a header to my table, but unfortunately it is not displayed correctly.
The htableHaderView is resized to the size of my imagesScrollView, but only half of it is displayed the rest area is blank.

- (void)viewDidLoad
{
    [super viewDidLoad];

    ImagesViewController *imagesScrollView = [[ImagesViewController alloc] initWithNibName:@"ImagesViewController" bundle:nil];


    tableView.tableHeaderView = imagesScrollView.view;
    imagesScrollView = nil;

}

Thanks for helping

I tried the following code:

ViewController.h

#import <UIKit/UIKit.h>
@interface ViewController : UITableViewController
@end

ViewController.m

#import "ViewController.h"
#import "ImagesViewController.h"
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
    ImagesViewController *imageVC  = [[ImagesViewController alloc] initWithNibName:@"ImagesViewController" bundle:nil];
    [[self tableView] setTableHeaderView:[imageVC view]];
    imageVC = nil;
}
@end

ImagesViewController.h

#import <UIKit/UIKit.h>
@interface ImagesViewController : UIViewController
@property (strong, nonatomic) IBOutlet UIScrollView *ScrollView;
@property (strong, nonatomic) IBOutlet UIView *ViewInScrollView;
@end

ImagesViewController.m

#import "ImagesViewController.h"
@implementation ImagesViewController
@synthesize ScrollView;
@synthesize ViewInScrollView;
- (void)viewDidLoad {
    [super viewDidLoad];
    [[self ViewInScrollView] setFrame:CGRectMake(0, 0, 768 * 2, 400)];
    [[self ViewInScrollView] setBackgroundColor:[UIColor orangeColor]];
    [[self ScrollView] setContentSize:[[self ViewInScrollView] frame].size];
}
@end

ImagesViewController‘s xib is a view, 768 wide by 200 tall (I made an iPad-based UITableView single-view application). Inside its view is a UIScrollView, set to take up the entire [view frame] area. Then I put a UIView inside of it.

My testing gives me a header that is an orange rectangle, and I can scroll it around as you would expect. This leads me to believe that maybe you need to check the shocks/struts of your imagesScrollView in Interface Builder. Make sure all of the margins and widths are fixed/flexible as you need for it to display properly.
