Image In Scroll View - iphone

Question

I am using the following code to try and display an image in a UIScrollView.
[self.jarView addSubview:imgView];
It does not work. However, it works when I add the subview to my normal view. My UIScrollView is called jarView and imgView is a UIImageView.
Thanks

Answer 1

This works fine for me:
UIScrollView *scrollview;
scrollview= [[UIScrollView alloc] initWithFrame:CGRectMake(,,,)];// set scroll view size
view = [[UIView alloc] initWithFrame:CGRectMake(y1,x1,y2,x2)]; //set the view size
UIImage *image1 = [UIImage imageNamed:imageName];
image=[[UIImageView alloc]initWithImage:image1];// take image size according to view
[view addSubview:image];
[scrollview addSubview:view];
[view release];
At last define how much scrollview is scroll:
scrollview.contentSize = CGSizeMake(width,height);

Answer 2

Make sure that your scrollView.contentSize property value is set correctly (width and height should be > 0).

Here I am posting my answer. Try it.
You can load all the images to an array. And you can design a view having one image view and try the below code:
array name: examplearray and view name :exampleview
-(void)updateImagesInScrollView
{
int cnt = [examplearray count];
for(int j=0; j< cnt; ++j)
{
NSArray *nibContents = [[NSBundle mainBundle] loadNibNamed:#"exampleview"
owner:self
options:nil];
UIView *myView = [nibContents objectAtIndex:0];
exampleview * rview= (exampleview *)myView;
/* you can get your image from the array and set the image*/
rview.imageview.image = yourimage;
/*adding the view to your scrollview*/
[self.ScrollView addSubview:rview];
}
/* you need to set the content size of the scroll view */
self.ScrollView.contentSize = CGSizeMake(X, self.mHorizontalScrollView.contentSize.height);
}

I am giving you my sample code. In this code i add multiple images on scroll view and this work fine for me:
UIScrollView *scrollview;
- (void)anyFunction
{
scrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 30, 320, 50)];
NSInteger viewcount = [cat_Products count]; // if you have four content your view count is 4..(four)..in my case i fetch it from database
CGFloat y2 = 0;
UIView *view;
UIImageView *imageView;
NSString *imageName;
for(int i = 0; i< viewcount; i++)
{
CGFloat y = i * 64;
y2 = y2 + 64;
view = [[UIView alloc] initWithFrame:CGRectMake(y, 0, y2, 50)];
imageName = [[NSString alloc] initWithFormat:#"c%i", (i + 1)]; // my image name is c1, c2, c3, c4 so i use this
UIImage *image1 = [UIImage imageNamed:imageName];
imageView = [[UIImageView alloc] initWithImage:image1];
[view addSubview:imageView];
[scrollview addSubview:view];
[view release];
[imageView release];
[imageName release];
}
scrollview.contentSize = CGSizeMake(viewcount*64,0); //viewcount*64 because i use image width 64..and second parameter is 0..because i not wants vertical scrolling...
[myView addSubview:scrollview];
[scrollview release];
}
I hope this helps.
