这个问题基于Detach子目录到单独的Git存储库中

我想分离一对,而不是分离一个子目录.例如,我当前的目录树如下所示:

/apps
  /AAA
  /BBB
  /CCC
/libs
  /XXX
  /YYY
  /ZZZ

而我想这样做:

/apps
  /AAA
/libs
  /XXX

该--subdirectory-filter参数git filter-branch将无法工作,因为它在第一次运行时除去了给定目录之外的所有内容.我认为使用--index-filter所有不需要的文件的参数会起作用(尽管很乏味),但如果我尝试不止一次运行它,我会得到以下消息:

Cannot create a new backup.
A previous backup already exists in refs/original/
Force overwriting the backup with -f

有任何想法吗？TIA

我现在遇到一个奇怪的问题,即一个存储NSDictionary的NSUserDefaults,然后取回其转换为一个NSCFString.

这是我保存数据的地方:

- (void)saveProgress
{
    // Save our progress to the user defaults.
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSMutableDictionary *progressDict = [NSMutableDictionary dictionary];
    if ([defaults objectForKey:@"session_progress"] != nil) {
        [progressDict addEntriesFromDictionary:[defaults dictionaryForKey:@"session_progress"]];
    }
    NSMutableDictionary *targetsDict = [NSMutableDictionary dictionary];
    if ([progressDict objectForKey:@"targets"] != nil) {
        [targetsDict addEntriesFromDictionary:[progressDict objectForKey:@"targets"]];
    }
    NSMutableDictionary *trackableDict = [NSMutableDictionary dictionary];
    if ([targetsDict objectForKey:@"mda_sao_ext_04"]) {
        [trackableDict addEntriesFromDictionary:[targetsDict objectForKey:@"mda_sao_ext_04"]];
    }
    [trackableDict setObject:[NSNumber numberWithBool:YES]
                      forKey:@"viewed"];
    NSLog(@"SAVE Trackable %@ %@", [trackableDict class], trackableDict);
    [targetsDict setObject:trackableDict …
