Images in a Scroll View
Tuesday, September 1st, 2009
I know that when I was a beginning iPhone developer doing things that seem so simple now weren’t so simple back then. Just because I didn’t know any better and was unaware of the tools and API’s available to me.
One thing that I’ve been doing a lot recently is putting several images in a UIScrollView, so I thought I’d post the barebones version of the code here in case anyone finds it useful. Hopefully I’ll be able to add more snippets in the future.
#define IMAGE_WIDTH 320
#define IMAGE_HEIGHT 416
- (void)viewDidLoad
{
[super viewDidLoad];
NSArray *photos = nil; // TODO – fill with your photos
// note that the view contains a UIScrollView in aScrollView
int i=0;
for ( NSString *image in photos )
{
UIImage *image = [UIImage imageNamed:[photos objectAtIndex:i]];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.clipsToBounds = YES;
imageView.frame = CGRectMake( IMAGE_WIDTH * i++, 0, IMAGE_WIDTH, IMAGE_HEIGHT);
[aScrollView addSubview:imageView];
[imageView release];
}
aScrollView.contentSize = CGSizeMake(IMAGE_WIDTH*i, IMAGE_HEIGHT);
aScrollView.delegate = self;
}
#define IMAGE_HEIGHT 416
- (void)viewDidLoad
{
[super viewDidLoad];
NSArray *photos = nil; // TODO – fill with your photos
// note that the view contains a UIScrollView in aScrollView
int i=0;
for ( NSString *image in photos )
{
UIImage *image = [UIImage imageNamed:[photos objectAtIndex:i]];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.clipsToBounds = YES;
imageView.frame = CGRectMake( IMAGE_WIDTH * i++, 0, IMAGE_WIDTH, IMAGE_HEIGHT);
[aScrollView addSubview:imageView];
[imageView release];
}
aScrollView.contentSize = CGSizeMake(IMAGE_WIDTH*i, IMAGE_HEIGHT);
aScrollView.delegate = self;
}
