SDWebimage如何获取缓存大小以及清除缓存

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];  

}
