Question

I have 2 scrollviews and 1 imageview.

now Inside Main scrollview I have another scrollview and in this scrollview I have image.

so, my Main Scrollview named “ScrollView” and sub scrollview named “scrView“

now I am able to add “scrView” inside “ScrollView” but I can not see my image inside “scrView“

My coding is as follows:

int numberOfPages = 10;
    [scrollView setPagingEnabled:YES];
    [scrollView setContentSize:CGSizeMake(scrollView.bounds.size.width * numberOfPages, scrollView.bounds.size.height)];

    CGRect pageFrame;
    CGRect imageFrame;
    UIImageView *imageView;

    for(int i=0; i < numberOfPages; i++)
    {
        pageFrame = CGRectMake(i * scrollView.bounds.size.width+50, 0.0f, scrollView.bounds.size.width-100, scrollView.bounds.size.height);
        UIScrollView *scrView = [[UIScrollView alloc] init];
        imageFrame = CGRectMake(i * scrView.bounds.size.width, 0.0f, scrView.bounds.size.width, scrView.bounds.size.height);
        imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image1.jpg"]];
                    [scrView setFrame:pageFrame];
        [imageView setFrame:imageFrame];
        [scrView setBackgroundColor:[UIColor redColor]];

        [scrollView addSubview:scrView];
        [scrView addSubview:imageView];

        [imageView release];
    }

If you look at the code I have added imageView as a subView of scrView but I am not able to see image in simulator.

what is the problem?

share your ideas with me.

thanks…

This is working try this code.Problem was with your imageview frame

int numberOfPages = 10;
[scrollView setPagingEnabled:YES];
[scrollView setContentSize:CGSizeMake(scrollView.bounds.size.width * numberOfPages, scrollView.bounds.size.height)];

CGRect pageFrame;
CGRect imageFrame;
UIImageView *imageView;

for(int i=0; i < numberOfPages; i++)
{
    pageFrame = CGRectMake(i * scrollView.bounds.size.width+50, 0.0f, scrollView.bounds.size.width-100, scrollView.bounds.size.height);
    UIScrollView *scrView = [[UIScrollView alloc] initWithFrame:pageFrame];
    imageFrame = CGRectMake(0.0, 0.0f, scrView.bounds.size.width, scrView.bounds.size.height);

    imageView = [[UIImageView alloc] initWithFrame:imageFrame];
    imageView.image=[UIImage imageNamed:@"image1.jpg"];

   // [scrView setFrame:pageFrame];

    [scrView setBackgroundColor:[UIColor redColor]];
    [scrView addSubview:imageView];
    [scrollView addSubview:scrView];


    [imageView release];
}
