SDWebImage change cacheMaxCacheAge

Question

How I can change a static value cacheMaxCacheAge when I use SDWebImage? What way is good? I need to cache images for 5 minutes.

[SDWebImageManager sharedManager].imageCache.maxCacheAge = 300; – Englert

Answer 1

In SDWebImage 5.0+ maxCacheAge renamed to maxDiskAge. You can set maximum caching time in seconds like this.

Objetive-c

[SDImageCache sharedImageCache].config.maxDiskAge = 60 * 5; //5 minutes

Swift 4+

SDImageCache.shared.config.maxDiskAge = 60 * 5 //5 minutes

should maxDiskSize be maxDiskAge in your Objective C example? – Fidole

Thanks @Fidole for pointing out, both are different, updated my answer. – Vector

Answer 2

SDWebImage is providing maxCacheAge property to set the maximum caching time in seconds. We can use shared instance method to access this property.

[SDImageCache sharedImageCache].config.maxCacheAge = 60 * 5; //5 minutes

While this code may answer the question, providing additional context regarding why and/or how this code answers the question improves its long-term value. – Publius

Answer 3

SWIFT 5+ , SDWebImage 5.13 +, tvOS15+ and maybe other platforms

I found out that simply setting new maxDiskAge property on tvOS 15+ is not enough when storing image with SDImageCache.shared.store , but you indeed need to manually delete the old cache with deleteOldFiles() function. It happens in my case, even though the performing of old cache deletion is allegedly done by library itself after terminating the app as specified in following SO post. This might be only the case for tvOS, but I am not entirely sure if the problem persists also on another platforms. Here is the solution that worked for me:

Deleting expired cache:

SDImageCache.shared.deleteOldFiles()

Setting max cache disk time in seconds:

SDImageCache.shared.config.maxDiskAge = 100000

Storing images to disk:

SDImageCache.shared.store(image, forKey: key, toDisk: true)
