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;
- }
-
- return totalSize;
- }
- (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];
-
-
- 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];
- }
