NSString stringWithFormat with tabs instead of spaces

Question

你可以看到我在我的字符串之后添加了40个空格，但它从索引0开始。我可以用标签“\\ t”而不是空格“”来做同样的事吗？

NSString *firstString = [[NSString stringWithFormat:@"%@",stringToWrite] stringByPaddingToLength:40 withString:@" " startingAtIndex:0];

Answer 1

Yes @"\\t" will put tab instead of spaces.
Also, your line could be a bit more simple :

NSString *firstString = [stringToWrite stringByPaddingToLength:40
                                                    withString:@" "
                                               startingAtIndex:0];
