memory management

[ivano.malavolta]

Hi all,
I am working on an app in which I need to manage a gallery of 150
large-sized images.

I would like to reuse the ImageExample of Leaves, but I am afraid that
with such a high
number of large-sized images I will have big memory problems, can you
confirm me that?
Or, in Leaves memory is managed somewhere else within the framework?

Cheers,
Ivano

Ivano,

Leaves cache only holds 3 in memory:
- previous
- current
- next

Please let me know if you need help with your project.

Best,
Ryan

Hi Ryan,
thanks very much for the quick reply.
The problem is that in the example file:

https://github.com/shuhongwu/leaves-zoom-enhanced/blob/master/Classes/ImageExampleViewController.m

I see this:

- (id)init {
if (self = [super init]) {
images = [[NSArray alloc] initWithObjects:
[UIImage imageNamed:@"kitten.jpg"],
[UIImage imageNamed:@"kitten2.jpg"],
[UIImage imageNamed:@"kitten3.jpg"],
nil];
}
return self;
}

And I got quite scared of the various imageNamed calls!
My scenario is that I have 150 jpg images to show (I got them from a PDF),
each image is around 1 Mb.

Do you have any suggestions on how I could proceed from here?
At the moment, I am thinking to develop by myself a scrollview with
zoom and paging,
in which I can load and dealloc the images when needed...

Cheers,
Ivano
