High memory use

[CavalcanteLeo]

SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadImageWithURL:post.imageURL options:0 progress:^(NSInteger receivedSize, NSInteger expectedSize) 
{
    // float progress = (float)receivedSize/expectedSize;
    // [cell.imageViewFoto updateProgress:progress];
}
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
    if (image) {
        [cell.imageViewFoto setupImageView:post indexPath:indexPath isGrid:NO  image:image];
    }
}];

whats the size of the image you are trying to download?

[CavalcanteLeo]

about 500kb each...
showing in a collectionview, about 18 images at same time...
The problem occurs when i scroll the collectionview, and request more and more and more images...

Maybe i have to disable the memory cache and only store in disk.. but i have no idea how to deal with it

[mythodeia]

did you try setting these two:

[[SDImageCache sharedImageCache] setShouldDecompressImages:NO];
[[SDWebImageDownloader sharedDownloader] setShouldDecompressImages:NO];

by the way, whats the highest resolution of those images?

[CavalcanteLeo]

No, i havent, i will try this code...

The API returns me a lot of images already resized, so i choose witch one to use, depending of the iPhone resolution(100x100, 200x200, 500x500, 1000x1000, 1500x1500, 2000x2000)
in this particular case, im using the 500x500 ( but the print of the collectionview with the images was using 100x100 for testing)

[CavalcanteLeo]

Btw, where should I use this code? appdelegate or viewcontroller?

[mythodeia]

should be before you make your requests. try the appdelegate

[CavalcanteLeo]

On viewcontroller nothing changed... still increasing memory

[CavalcanteLeo]

    "thumbnail": {
      "height": 100,
      "url": "https://timehi.s3-sa-east-1.amazonaws.com/post/160c6ef0a2d2db2a6502.jpg",
      "width": 100
    }

the 100x100 pixels image is about 4kb...

and increase a lot of memory

[mythodeia]

why are you using SDWebImageManager's downloadImageWithURL:... and not [cell.imageView sd_setImageWithURL:...
can you try the demo project? do you see the same increase in memory there too?

[CavalcanteLeo]

i cant show the image as soon as the dowload finish, i have to implement some logic before with the image...

[mythodeia]

if you perform extra actions on the image you could use this

did you try the demo project? does it show the same memory increase?

[CavalcanteLeo]

i will try right now

[CavalcanteLeo]

it still increasing memory with the code bellow:

[cell.image sd_setImageWithURL:downloadImg completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
    if (image) {
        BOOL isGrid = YES;
        if (self.headerProfile.segmentedControl.selectedSegmentIndex == 1) {
            isGrid = NO;
            cell.image.delegate = self;
        }else{
            cell.image.delegate = nil;
        }
        [cell.image setupImageView:post indexPath:indexPath isGrid:isGrid image:image];
    }
}];

[CavalcanteLeo]

also have checked all strong and weak properties referencies... just to double check if the ARC is releasing all object correctly, but it's all right with it

[mythodeia]

try the demo project with your API urls but without doing anything extra to the image after download. do you still see any increase in memory?
