In my application is like (Montage) to show a lot of images, videos , music and also to mainatain the image id for its own identification and other purpose. I need to know the whether the all image is show using sdwebimage in imageview or after i logged in all images to download and saved it to local files ? Tell me which is good ?
SDWebImage is already providing caching mechanism, so instead of downloading all images at once use SDWebImage
SDWebImage also using lazy load, so the performance of your application will be good.
But if you try to download all images at once, it will degrade your app performance. You need to wait before loading view till downloading end.

I am having a sample application which is having networking images, how to display preloaded cache images when navigating between pages. Because it is taking some time for loading from api calls. instead of placeholder how to display same image which loaded previously.
I am trying to use flutter_cache_manager 0.1.1, cached_network_image 0.4.1+1
plugins but still unable to achieve.
I think you are looking for FadeInImage where you can set a placeholder image until the actual image becomes available.
The actual image can come from various ImageProviders like NetworkImageWithRetry or similar.
I'm using SDWebImage in my project to load and cache images from web. I want to use SwiftPhotoGallery as a gallery library. In the documentation, it states that "SwiftPhotoGallery integrates seamlessly with SDWebImage".
However I didn't find a way how to integrate. Because SwiftPhotoGallery is working with UIImages (SwiftPhotoGalleryDataSource method required UIImage as a result) and SDWebImage is working with UIImageViews (it sets image automatically, when download is finished).
I have around 1000 ’s of Images, I want show them in my app. What are the possibilities to do that..
The ideas which I’m thinking
1.Saving all images in phone gallery. accessing images form gallery… but It seems not possible as each iOS app has its own sandbox.
2.Saving in my bundle which will increase the memory size.
In android there is a control called “ViewPager”, how can i achieve the same control in iOS ….
Tried scrollview with paging technique but crashes due to memory ....
Please guide me…..
I dont think you can show images from the gallery directly to your application . But you can store it into document directly , for that you have to first pick images from the gallery . you can refer
How to load photos from photo gallery and store it into application project?
And next time when you start application you can load images from the document directory so you dont need to go to the gallery again .
Hi i am pretty new to IOS so pardon for silly questions . I am working on an app which loads large images in a tableview. Images to be loaded are of large size (>5MB) so i am trying to resize the image into thumbnails ,cache it and the load it asynchronously to table view. i found many ways and discussions for doing the same for network images (SDWebImages etc.) but i couldn't get anything for doing the same with local images (camera/photo library). Can any one tell me how to implement it?
You need to implement lazy loading of image along with asynchronous loading of images.

Say I load a webpage with an image on it. Is there a way to reuse this loaded image within a UIImageView without reloading the image from a url?
If the image is cached by URL loading system, it will come from the cache when you try to load it.
Sorry I can't give a large explanation as im on y phone but I feel like what your looking for is 'core data store' there are several examples of how to use this framework, but it's quite complicated and has a large learning curve with ios development.
Also you say 'a' uiwebview. Does that mean that the URL your accessing to show within your uiwebview is static? If so, just copy and save the image and store the image in your project for future reference.
Or are you allowing the user to keep swapping through links in the uiwebview and store all those images that popup on the web page?
Sorry I'm just unclear with the question... Please no down votes :)
