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];
- }
