I am unable to download the image in Objective c Using SDWebImage 4.4.5 version., I tried the following , nothing worked.
Try 1:
[self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] completed:^(UIImage * _Nullable image, NSError * _Nullable error, SDImageCacheType cacheType, NSURL * _Nullable imageURL) {
}];
Try 2:
[self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] placeholderImage:nil options:SDWebImageRefreshCached completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) { if(image != nil){
self.thumbnailImageView.image = image;
} else {
NSLog(#"Photo Not Available, fetch");
[self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] placeholderImage:nil options:SDWebImageRefreshCached completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
if(image != nil) { NSLog(#"Lo Res Image Loaded by %ld from '%#'", (long)cacheType, imageURL);
self.thumbnailImageView.image = image;
} else {
self.thumbnailImageView.image = nil;
} }];
} }];
Try 3:
[[SDWebImageDownloader sharedDownloader] downloadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDownloaderUseNSURLCache progress:nil completed:^(UIImage *image, NSData *data, NSError *error, BOOL finished) {
}];
Try 4:
SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager loadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDelayPlaceholder progress:^(NSInteger receivedSize, NSInteger expectedSize, NSURL * _Nullable targetURL) {
} completed:^(UIImage * _Nullable image, NSData * _Nullable data, NSError * _Nullable error, SDImageCacheType cacheType, BOOL finished, NSURL * _Nullable imageURL) {
}];
Try 5:
SDWebImageDownloader *manager = [SDWebImageManager sharedManager].imageDownloader;
[manager setValue:#"application/vnd.learning.events.v1+json" forHTTPHeaderField:#"Accept"];
[manager setValue:#"en-US" forHTTPHeaderField:#"Accept-Language"];
[manager setValue:#"application/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
//[manager setValue:savedEmail forHTTPHeaderField:#"Email"];
[manager setValue:savedToken forHTTPHeaderField:#"Authorization"];
[manager downloadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDownloaderHighPriority progress:^(NSInteger receivedSize, NSInteger expectedSize, NSURL * _Nullable targetURL) {
} completed:^(UIImage * _Nullable image, NSData * _Nullable data, NSError * _Nullable error, BOOL finished) {
self.thumbnailImageView.image = image;
}];
In all the above cases, getting the following error:
Error Domain=NSURLErrorDomain Code=-999 "cancelled" UserInfo={NSErrorFailingURLStringKey=https://thisisnotcorrecturl.net/api/BAImage?ActionFlagId=97&id=615, NSErrorFailingURLKey=https://thisisnotcorrecturl.net/api/BAImage?ActionFlagId=97&id=615, _NSURLErrorRelatedURLSessionTaskErrorKey=(

), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <92586538-B07D-46FB-8694-3B29AA3F0CB4>.<7>, NSLocalizedDescription=cancelled}
Earlier, we used v3.5.4 version used, able to download the image with the following code. It's working good.
[self.thumbnailImageView setImageWithURL:[NSURL URLWithString:thumbnailURLString]
placeholderImage:nil
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
if (image != nil){
self.thumbnailImageView.image = [self imageResizingToAspetRatio:image];
}
}];
Kindly let me know if did any mistake, or any suggestions.
Update 1:
Tried to download the image using post man. Kindly check the image.
The same image URL is working on SDWebImage v3.5.4 after i upgraded to SDWebImage v4.4.5, it is not lodging the image.
Is there any configurations am i missing? Installed pod 'SDWebImage/WebP' also, added SD_WEBP=1 in Build settings -> Preprocessor macros.
Error: Error Domain=SDWebImageErrorDomain Code=0 "Downloaded image has 0 pixels" UserInfo={NSLocalizedDescription=Downloaded image has 0 pixels}

Basically, SDWebImage has no issue for downloading them from any URL if the URL contains an image.
But in your case, you have tried to get an image from JSON. Your server API returns a JSON object that contains the image as base64String. When you get the JSON response then you need to get the base64String from json and then create an image from the base64String.
You can use this method for decoding string to image using Objective C.
- (UIImage *)decodeBase64ToImage:(NSString *)strEncodeData {
NSData *data = [[NSData alloc]initWithBase64EncodedString:strEncodeData options:NSDataBase64DecodingIgnoreUnknownCharacters];
return [UIImage imageWithData:data];
}
First, update pod and try SDWebImage pod version 3.8.2.
And the second thing is to check your image URL. because I personally test image download with this pod version and downloading functionality is working.
I faced the same issue and I was trying webP images. I realised later that I need to add webP coder to SDImageCodersManager. Something like
SDImageCodersManager.shared.addCoder(SDImageWebPCoder.shared)
I did this in AppDelegate.
If you are suffering such type issue from SDWebImage library you can go with other one as well which are supporting base64 string object
One of best library I found is "Kingfisher"
Hope you like this and it will solve your issue.
I am using SDWebImage to get image from url. I want to get the size of remote image in order to do some layout calculation. Since I only know the url of the image, how can I get it from SDWebImage object?
please try this one, Its may be work for you
-(UIImage *)downloadImageAsync:(NSString *)imageKey
{
NSLog(#"image key : %#",imageKey);
__block UIImage *returnedImage;
SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadWithURL:[NSURL URLWithString:imageKey] options:0 progress:^(NSUInteger receivedSize, long long expectedSize){
NSLog(#"received size %d expected size %lld", receivedSize, expectedSize);
}completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType,BOOL finished){
if(image && finished) {
returnedImage = image;
}
}];
if(returnedImage == nil) {
NSLog(#"Returned Image Nil");
}
return returnedImage;
}
If I just download like this, it store in default folder.
SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadImageWithURL:[NSURL URLWithString:urlStr]
options:0
progress:^(NSInteger receivedSize, NSInteger expectedSize) {
// progression tracking code
}
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
if (image)
{
}
}];
How can I group images into different folder? I saw initWithNamespace but I don't know how to use. If I use that method, how can I refer to default folder again also?
I am using SDWebImageImagemanger to hadnle asyn call and caching. However it does not return the image to the cell.imageview.view. Here is the code:
NSString *imageURLString=[[tableData objectAtIndex:indexPath.row] valueForKey:#"picture"];
NSURL *url = [NSURL URLWithString:imageURLString];
SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadWithURL:url
options:0
progress:^(NSInteger receivedSize, NSInteger expectedSize)
{
// progression tracking code
}
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished)
{
if (image)
{
cell.imageView.image = image;
}
}];
You should use it this way:
NSString* imageURL = [[tableData objectAtIndex:indexPath.row] valueForKey:#"picture"];
[cell.imageView setImageWithURL:[NSURL URLWithString:imageURL]];
For that, first import the category:
#import <SDWebImage/UIImageView+WebCache.h>
Please note that you don't use the manager at all, you just use the UIImageView+WebCache category provided by the library, which gives you the setImageWithURL: method. There are other variants of the method which allows you to keep track of the download process, a completion handler, etc.
I'm using SDWebImage to fetch images in my project, but I'm facing just one issue that I haven't been able to solve so far.
Basically if an image has a temporary redirect (307 redirect which nowadays is a standard code for redirect) the library doesn't follow the redirect and just returns an error.
This doesn't happen with images with a 302 redirect. Any ideas how to solve this problem?
PS: Just in case someone needs the code on how I'm loading the images, I'm doing this:
SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadWithURL:imageURL
options:0
progress:^(NSInteger receivedSize, NSInteger expectedSize) {
// progression tracking code
}
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished) {
if (image) {
[_photo setImage:image];
}
}];
