    NSFileManager *fileManager = [[[NSFileManager alloc] init] autorelease];

    NSURL *directoryURL = [NSURL URLWithString:@"toolKitRes/model"];   // URL pointing to the directory you want to browse

    NSArray *keys = [NSArray arrayWithObject:NSURLIsDirectoryKey];

    

    NSDirectoryEnumerator *enumerator = [fileManager

                                         enumeratorAtURL:directoryURL

                                         includingPropertiesForKeys:keys

                                         errorHandler:^(NSURL *url, NSError *error) {

                                             // Handle the error.

                                             // Return YES if the enumeration should continue after the error.

                                             return YES;

                                         }];

    vector<string> fullPathList;

        NSError *error;

        NSNumber *isDirectory = nil;

        if (! [url getResourceValue:&isDirectory forKey:NSURLIsDirectoryKey error:&error]) {

            // handle error

            

        }

        else if (! [isDirectory boolValue]) {

            // No error and it’s not a directory; do something with the file

            NSString *str_NS=[[url absoluteString] stringByReplacingPercentEscapesUsingEncoding: NSUTF8StringEncoding];

            NSLog(@"%@",str_NS);

            

            string fullPath=[str_NS cStringUsingEncoding:NSASCIIStringEncoding];

            filePathList.push_back(fullPath);

        }else if([isDirectory boolValue]){

            NSString *str_NS=[[url absoluteString] stringByReplacingPercentEscapesUsingEncoding: NSUTF8StringEncoding];

           NSLog(@"%@",str_NS);

            

            string fullPath=[str_NS cStringUsingEncoding:NSASCIIStringEncoding];

            directoryPathList.push_back(fullPath);

        

        }

    }

}

注意：要用

NSString *str_NS=[[url absoluteString] stringByReplacingPercentEscapesUsingEncoding: NSUTF8StringEncoding]; (见参考[2])

不能像 参考[1] 中那样写成

NSString *str_NS=[url absoluteString];

否则如果路径中带有空格，则会变成%20。
