Question

I want to display Image,Title name,and two left right buttons. That I have done successfully.
Here is the code:

    UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 200, 100)];

    UIButton *leftButton = [[UIButton alloc]init];
    [leftButton setImage:[UIImage imageNamed:@"previous-arrow.png"] forState:UIControlStateNormal];
    [leftButton addTarget:self action:@selector(goPrevious:) forControlEvents:UIControlEventTouchUpInside];
    [leftButton setFrame:CGRectMake(20, 50, 14, 13)];

    UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Title.png"]];
    [imageView setFrame:CGRectMake(leftButton.frame.origin.x+leftButton.frame.size.width+4, 20, 50, 50)];

    UILabel *nameLabel = [[UILabel alloc]initWithFrame:CGRectMake(imageView.frame.origin.x+imageView.frame.size.width+4, 30, 100, 40)];
    NSString *cName = [NSString stringWithFormat:@"%@",[NameArray objectAtIndex:indexPath.section]];

    [nameLabel setTextColor:[UIColor whiteColor]];
    [nameLabel setBackgroundColor:[UIColor clearColor]];
    [nameLabel setContentMode:UIViewContentModeScaleAspectFill];
    [nameLabel setTextAlignment:UITextAlignmentLeft];
     CGSize expectedLabelSize = [cName sizeWithFont:nameLabel.font 
                                        constrainedToSize:CGSizeMake(100, 40) 
                                            lineBreakMode:nameLabel.lineBreakMode]; 
    [nameLabel setFrame:CGRectMake(imageView.frame.origin.x+imageView.frame.size.width+4, 35, expectedLabelSize.width, expectedLabelSize.height)];
    nameLabel.text=cName;

    UIButton *rightButton = [[UIButton alloc]init];
    [rightButton setImage:[UIImage imageNamed:@"next-arrow.png"] forState:UIControlStateNormal];
    [rightButton setFrame:CGRectMake(nameLabel.frame.origin.x+nameLabel.frame.size.width+4, 50, 14, 13)];
    [rightButton addTarget:self action:@selector(next:) forControlEvents:UIControlEventTouchUpInside];

    [view addSubview:nameLabel];
    [view addSubview:imageView];
    [view addSubview:leftButton];
    [view addSubview:rightButton];

    self.navigationItem.titleView = view; 

This code is written in cellForRowAtIndexPath. The view is showing properly on navigation bar but after scrolling the tableview. Initially it is displaying on wrong coordinates.

Please Suggest.

Put this code in viewWillAppear or viewDidAppear. It’s not meant to be in tableView protocol!
