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;}

新版的SDImageCache类，已增加此方法

[[SDImageCache sharedImageCache] getSize];

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];}
