Question

我使用SDImageCache从表视图缓存图像，但是当向下滚动时，内存不断增加。所以我检查了库并在SDImageCache.h中找到了属性来设置maxMemoryCost并期望缓存将被删除超过此限制。但在我的测试中，[SDImageCache sharedImageCache]不会删除任何内容。所以这个房产目前什么也没做。

应用程序最终会因巨大的内存大小而崩溃。

您好我遇到了同样的问题并修复了我的AppDelegate didFinishLaunchingWithOptions方法

上添加这一行

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    SDWebImageDownloader.shared().shouldDecompressImages = false
    SDImageCache.shared().shouldDecompressImages = false
}

这应该可以解决问题，这里建立了https://github.com/SDWebImage/SDWebImage/issues/1544#issuecomment-423445538

SDImageCache.shared().config.maxCacheAge = 3600 * 24 * 7 //1 Week

SDImageCache.shared().maxMemoryCost = 1024 * 1024 * 20 //Aprox 20 images

//SDImageCache.shared().config.shouldCacheImagesInMemory = false //Default True => Store images in RAM cache for Fast performance

SDImageCache.shared().config.shouldDecompressImages = false

SDWebImageDownloader.shared().shouldDecompressImages = false

SDImageCache.shared().config.diskCacheReadingOptions = NSData.ReadingOptions.mappedIfSafe

希望这可以帮助你，让我知道

对我来说，清除内存缓存可以解决此问题。

- (void)viewWillDisappear:(BOOL)animated {
    [self clearImageCacheFromMemory];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    [self clearImageCacheFromMemory];
    // Dispose of any resources that can be recreated.
}

-(void)clearImageCacheFromMemory{
    SDImageCache *imageCache = [SDImageCache sharedImageCache];
    [imageCache clearMemory];
}

SDImageCache set maxMemoryCost不执行任何操作。记忆力不断增加
