SDWebImage not displaying image from URL which is too long and with some special characters.
image URL is:
http://akns-images.eonline.com/eol_images/Entire_Site/2018223/rs_600x600-180323073745-600-michael-davidson-fdny-032218.jpg?fit=around%7C450:350&crop=450:350;center,top&output-quality=100
[albumImageview sd_setImageWithURL:[NSURL URLWithString:aboveURL] placeholderImage:[UIImage imageNamed:placeholder] options:SDWebImageRefreshCached];
Use the following method
[albumImageview sd_setImageWithURL:[NSURL URLWithString:#"http://akns-images.eonline.com/eol_images/Entire_Site/2018223/rs_600x600-180323073745-600-michael-davidson-fdny-032218.jpg?fit=around%7C450:350&crop=450:350;center,top&output-quality=100"] placeholderImage:[UIImage new] completed:^(UIImage * _Nullable image, NSError * _Nullable error, SDImageCacheType cacheType, NSURL * _Nullable imageURL) {
albumImageview.image = image;
}];

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=(

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 want dynamic height image show in tableview, image is come from url so I am using the sdwebimage.
Sdwebimage set image in background thread.
[self.imageView sd_setImageWithURL:[NSURL URLWithString: encodedurl1] completed:^(UIImage * _Nullable image, NSError * _Nullable error, SDImageCacheType cacheType, NSURL * _Nullable imageURL) {
}];
I am update the constraint height of image view in this thread.
[self.imageView sd_setImageWithURL:[NSURL URLWithString: encodedurl1] completed:^(UIImage * _Nullable image, NSError * _Nullable error, SDImageCacheType cacheType, NSURL * _Nullable imageURL) {
CGFloat multiplier = (CGRectGetWidth(self.imageView.bounds) / image.size.width);
[self.imageViewHeightConstraint setConstant:multiplier * image.size.height];
}];
This code is helpful for me but I get image size in background thread
So, I take a time to update the height of constraint image view
I am search and goggling last 2 days.
This type issue get many developer, but not answer in any question in stack overflow.
do the update in main thread like
[self.imageView sd_setImageWithURL:[NSURL URLWithString: encodedurl1] completed:^(UIImage * _Nullable image, NSError * _Nullable error, SDImageCacheType cacheType, NSURL * _Nullable imageURL) {
dispatch_async(dispatch_get_main_queue(), ^{
CGFloat multiplier = (CGRectGetWidth(self.imageView.bounds) / image.size.width);
[self.imageViewHeightConstraint setConstant:multiplier * image.size.height];
[self setNeedsUpdateConstraints];
});
}];
Try this Helper method which created for my project.
-(void)imageWithURL:(NSURL *)imageurl WithIndexPath:(NSIndexPath *)indexpath WithCallback:(void(^)(UIImage *downloadedImage,BOOL isCache , NSIndexPath *imageIndexPath))callback{
if (![[SDWebImageManager sharedManager ]diskImageExistsForURL:imageurl]) {
[[SDWebImageManager sharedManager]downloadImageWithURL:imageurl options:0 progress:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
// resize image here
callback(image , NO,indexpath);
}];
}
else{
UIImage *image = [[SDImageCache sharedImageCache] imageFromDiskCacheForKey:[imageurl absoluteString]] ;
// resize image here
callback(image, YES ,indexpath);
}
}
Call this method in cellForRowAtIndexPath
dispatch_async( dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[self imageWithURL:[NSURL URLWithString:objPreparations.strImageURL] WithIndexPath:indexPath WithCallback:^(UIImage *downloadedImage, BOOL isCache, NSIndexPath *imageIndexPath) {
if (downloadedImage) {
dispatch_async( dispatch_get_main_queue(), ^{
UITableViewCell *existcell = [tableView cellForRowAtIndexPath:imageIndexPath];
if (existcell) {
// assign image to cell here
[tableView reloadRowsAtIndexPaths:#[imageIndexPath] withRowAnimation:UITableViewRowAnimationNone];
}
});
}
}];
});
Dont Forgot
In viewDidLoad
tblView.estimatedRowHeight = 44.0 ;
tblView.rowHeight = UITableViewAutomaticDimension;
And also Give top,bottom,leading,trailing constraints to imageview and greater than equal height constraint to imageview
in my application i am downloading an image from url from webservice using SDWebImage Library. I have nothing problem with this code
[imgQuestionContainer sd_setImageWithURL:[NSURL URLWithString:#"url"] placeholderImage:#"abc.png" options:SDWebImageProgressiveDownload];
with above code i have successfully load the image in imageview...
But my problem is that if i have url for the image but image is not available at that particular path of url. So, how to know that image is not available so i can load next data.
Thanks.
[cell.imageView setImageWithURL:[NSURL URLWithString:#"http://www.domain.com/path/to/image.jpg"]
placeholderImage:[UIImage imageNamed:#"placeholder.png"]
success:^(UIImage *image) {
if(image){
}else{
}
}
failure:^(NSError *error) {
}];
];
This is what exactly i wanted.
[imgQuestionContainer sd_setImageWithURL:[NSURL URLWithString:[[arrOfLoadedPuzzel objectAtIndex:0] objectForKey:#"puzzle_question"]]
placeholderImage:nil
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL)
{
if(error)
{
// image is not available
}
else
{
// image is available
}
}];
I tried over 100 methods to animate images using SDWebImage but always fail. Do I understand good to using blocks? I am having IBOutlet property image names images1. I made array to store values and animate 3 images.
NSMutableArray *imagegallery = [[NSMutableArray alloc] init];
NSLog(#"IMAGES-%#", imagegallery);
[self.images1 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:#"Img1"]]
placeholderImage:[UIImage imageNamed:#"placeholder.png"]
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
[imagegallery addObject:image];
NSLog(#"Ima1-------%#", image);
}];
[self.images1 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:#"Img2"]]
placeholderImage:[UIImage imageNamed:#"placeholder.png"]
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
[imagegallery addObject:image];
}];
[self.images1 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:#"Img3"]]
placeholderImage:[UIImage imageNamed:#"placeholder.png"]
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
[imagegallery addObject:image];
}];
self.images1.animationImages = imagegallery; //this line gets error
self.images1.animationDuration = 0.5;
[self.view addSubview:self.images1];
[self.images1 startAnimating];
I think when you set self.images1.animationImages = imagegallery because your image couldn't be loaded yet, method setImageWithURL:placeholderImage:completed: is an asynchronous function. you should try another way
like:
Animate images in uiimageview
The problem is that imageGallery contains strings as well as the images you add in the completed block. There's no reason to set imageGallery to be a copy of animatee in the first place since you never use those strings in imageGallery. Just create a new empty mutable array for imageGallery.
I am trying to show progress view with SDWebImage but when i try below code then it return "0" in "receivedSize"
[cell. ImageHotDish setImageWithURL:[NSURL URLWithString:picName]
placeholderImage:[UIImage imageNamed:nil]
options:0 progress:^(NSUInteger receivedSize, long long expectedSize) {
NSLog(#"Downloaded = %#",receivedSize);
} completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
[cell.ImageHotDish setImageWithURL:[NSURL URLWithString:picName]];
}];
I am getting null velue in "receivedSize"
Can any one tell me where i am doing wrong
I have already check this solution but its not showing progress but just an activity indicator. What i am trying to get how much image have been downloaded.
