UIImageView with ScrollView

[erdinc27]

i have an array with links of images. and i want to add them to my scrollView.i wrote that codes for that but it doesnt show anything. how i can do that ?

- (void)scrollViewDidScroll:(UIScrollView *)_scrollView {

	
	scrscroll.delegate = self;
	
	scrscroll.indicatorStyle = UIScrollViewIndicatorStyleDefault;
	scrscroll.clipsToBounds = YES;
	scrscroll.scrollEnabled = YES;
	scrscroll.pagingEnabled = YES;
	int i=0;
	CGFloat cx = 0;
	for ( ; i< [buyukResimLink count] ;i++)
	{
		UIImage *image = [UIImage imageWithData:[[NSData alloc] initWithContentsOfURL:[[NSURL alloc] initWithString:[buyukResimLink objectAtIndex:i]]]];
	
		UIImageView *resimView=[[UIImageView alloc] initWithImage:image];
		CGRect rect = resimView.frame;
		rect.size.height = image.size.height;
		rect.size.width = image.size.width;
		rect.origin.x = ((scrscroll.frame.size.width - image.size.width) / 2) + cx;
		rect.origin.y = ((scrscroll.frame.size.height - image.size.height) / 2);
		resimView.frame=rect;
		
		[scrscroll addSubview:resimView];
		[resimView	release];
		cx += scrscroll.frame.size.width;
	}
}

I don't see anywhere that you are setting the contentSize property for the scrollveiw?


On a side note: there are several memory leaks here

UIImage *image = [UIImage imageWithData:[[NSData alloc] initWithContentsOfURL:[[NSURL alloc] initWithString:[buyukResimLink objectAtIndex:i]]]];

Also, depending on what buyukReseimLink objectAtIndex:i is, if it's a remote URL, then there is gonna be a huge delay in each of these images downloading synchronously like this. Depending on their size, it could take a while before they are downloaded and anything shows up on your screen.

i wrote that in viewDidLoad like here

[scrscroll setContentSize: CGSizeMake(scrscroll.bounds.size.width * [buyukResimLink count], scrscroll.bounds.size.height)] ;

but my mistake was i didnt write this

scrscroll.delegate=self;

after that it works now. thanks for help and answer.
