SDWebImage corrupt images - iphone

Question

I'm using SDWebImage (2.7.3 framework) and I receive corrupt images, I can't understand exactly the problem. If is the code (memory...)
(notes:
I get the same error using the SDWebImage project instead of the framework.
I'm implementing "autorelease" and other kinds of memory management.
This problem arises on devices (iPad), but not in the simulator)
__block CALayer *layerCover = [[CALayer alloc] init];
layerCover.frame = CGRectMake(3, 3, COVER_WIDTH_IPAD_SMALL, COVER_HEIGHT_IPAD_SMALL);
[btn.layer addSublayer:layerCover];
[_scroll addSubview:btn];
[btn release];
//request or load Vods Images
[[SDWebImageManager sharedManager] downloadWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#M", vod.cover]]
delegate:self options:SDWebImageProgressiveDownload success:^(UIImage *image, BOOL cached) {
if (image) {
layerCover.contents = (id)image.CGImage;
}
[layerCover release];
} failure:^(NSError *error) {
[layerCover release];
}];
//another kind
UIImage * imageTv = [UIImage imageNamed:#"bgDefaultTvImage.png"];
UIImageView * bgTvImage = [[UIImageView alloc] initWithFrame:CGRectMake(startX, 20, imageTv.size.width, imageTv.size.height)];
[bgTvImage setImage:imageTv];
CGFloat sizeWithIcon = imageTv.size.width;
CGFloat sizeHeightIcon = imageTv.size.height;
__block UIImageView * bgImageicon = [[UIImageView alloc] initWithFrame:CGRectMake((bgTvImage.frame.size.width-sizeWithIcon)/2,
(bgTvImage.frame.size.height-sizeHeightIcon)/2,
sizeWithIcon,
sizeHeightIcon)];
bgImageicon.contentMode = UIViewContentModeScaleAspectFit;
[bgTvImage addSubview:bgImageicon];
[tvTopView addSubview:bgTvImage];
/*
* Request ProgramImage
*/
[[SDWebImageManager sharedManager] downloadWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#&width=300",program.ProgramImage.imageURL]]
delegate:self options:SDWebImageProgressiveDownload success:^(UIImage *image, BOOL cached) {
if (image) {
iconCanal = image;
[bgImageicon setImage:iconCanal];
}
[bgImageicon release];
}failure:^(NSError *error) {
[bgImageicon release];
}];
Xcode logs:
<Error>: ImageIO: JPEG Corrupt JPEG data: bad Huffman code
<Error>: ImageIO: JPEG Corrupt JPEG data: premature end of data segment

Answer 1

It seems to be the problem of SDWebImageProgressiveDownload flag. Try to disable it, for example like this:
[[SDWebImageManager sharedManager] downloadWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#&width=300",program.ProgramImage.imageURL]]
delegate:self options:0 success:^(UIImage *image, BOOL cached) {
if (image) {
iconCanal = image;
[bgImageicon setImage:iconCanal];
}
[bgImageicon release];
}failure:^(NSError *error) {
[bgImageicon release];
}];
