    sdwebimage如何获取缓存大小以及清除缓存

    1.找到SDImageCache类
    2.添加如下方法:

    - (float)checkTmpSize {
        float totalSize = 0;
        NSDirectoryEnumerator *fileEnumerator = [[NSFileManager defaultManager] enumeratorAtPath:diskCachePath];
        for (NSString *fileName in fileEnumerator) {
           NSString *filePath = [diskCachePath stringByAppendingPathComponent:fileName];
           NSDictionary *attrs = [[NSFileManager defaultManager] attributesOfItemAtPath:filePath error:nil];
           unsigned long long length = [attrs fileSize];
          totalSize += length / 1024.0 / 1024.0;
        } // NSLog(@"tmp size is %.2f",totalSize); return totalSize;
    }

    3.在设置里这样使用
    #pragma 清理缓存图片   
      
    - (void)clearTmpPics  
    {  
        [[SDImageCache sharedImageCache] clearDisk];  
      
    //    [[SDImageCache sharedImageCache] clearMemory];//可有可无   
      
        DLog(@"clear disk");      
      
        float tmpSize = [[SDImageCache sharedImageCache] checkTmpSize];  
      
        NSString *clearCacheName = tmpSize >= 1 ? [NSString stringWithFormat:@"清理缓存(%.2fM)",tmpSize] : [NSString stringWithFormat:@"清理缓存(%.2fK)",tmpSize * 1024];  
      
        [configDataArray replaceObjectAtIndex:2 withObject:clearCacheName];  
      
        [configTableView reloadData];  
    }
