There are many iOS apps that require tons of images to be simultaneously downloaded, stored, and presented to the end-user without negatively impacting a user’s experience. Shelby.tv is one of these apps.
A couple months ago I put together a solution to this problem in the form of an asynchronous image downloader, with optional cache-storage, that also utilizes Apple’s Grand Central Dispatch technology to swiftly obtain, store, and present these images to the end user. I call it Asynchronous Freeloader.
My implementation is/does the following:
- iOS 5+ Compatible
- ARC Compliant
- Image Scaling
- Disk Caching with Garbage Collection
- Support for Custom and Generic Placeholders
- Multithreaded Image Downloading and Processing (via Grand Central Dispatch)
The best part, all of this functionality is yours with one line of code:
+ (void)loadImageFromLink:(NSString *)webLinkToImage
forImageView:(UIImageView *)imageView
withPlaceholderView:(UIView*)placeholderView;The code and README can be found on the project’s Github page.
Enjoy!
Great tool, Arthur! Thanks for sharing!
