ios - 想知道我的 Xcode 项目中是否存在使用 objective-c 的目录？

Question

我使用此代码在项目中创建了一个目录

NSError * error = nil;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);    
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/createDirectory1"];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]) 
{
    [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
    NSLog(@"Create a new Dir");
}
else 
{
    NSLog(@"Dir already exist");
}

现在我想检查该目录是否存在？我怎样才能通过 Objective C 代码得到它？

    NSString *docPath = [NSSearchPathForDirectoriesInDomains (NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
    NSString *filePath=[NSString stringWithFormat:@"%@/createDirectory1", docPath];
    BOOL fileExists=[[NSFileManager defaultManager] fileExistsAtPath:filePath];
    if (!fileExists)
    {

    }
    else
    {
       // Your Code
    }
