__MACOSX 错处。

[ShouBinCheng]

解压产生__MACOSX文件夹，当资质文件没首字母小于M时下载后移除文件操作错误。 应修改为：

+ (void)formatSakuraPath:(NSString *)sakuraPath cleanCachePath:(NSString * _Nullable)cachePath {
    if (!sakuraPath || !sakuraPath.length) return;
    if (cachePath) {
        [TXSakuraManager tx_clearSakuraCacheWithPath:cachePath];
    }
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error = nil;
   //修改处 start
    NSMutableArray *folders = [fileManager contentsOfDirectoryAtPath:sakuraPath error:&error].mutableCopy;
    if ([folders containsObject:@"__MACOSX"]) {
        [folders removeObject:@"__MACOSX"];
    }
    //end
    NSString *folderName = sakuraPath.lastPathComponent;
    NSString *tempName = [folders.lastObject stringByAppendingString:folderName];
    NSString *moveItemPath = [sakuraPath stringByAppendingPathComponent:folders.lastObject];
    NSString *tempItemPath = [[sakuraPath stringByDeletingLastPathComponent] stringByAppendingPathComponent:tempName];
    [fileManager moveItemAtPath:moveItemPath toPath:tempItemPath error:&error];
    [fileManager removeItemAtPath:sakuraPath error:&error];
    [fileManager moveItemAtPath:tempItemPath toPath:sakuraPath error:&error];
#ifdef DEBUG
    NSLog(@"folders:%@", folders);
    NSLog(@"sakuraPath:%@--%@",sakuraPath, error);
#endif
}
