NSString stringWithFormat with tabs instead of spaces

提问by cyclingIsBetter

You can see that I add 40 spaces after my string but it starts at index 0. Can I do the same thing with tab "\t" instead of spaces " "?

您可以看到我在字符串后添加了 40 个空格,但它从索引 0 开始。我可以用制表符“\t”而不是空格“”来做同样的事情吗?

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

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

Yes@"\t"将放置制表符而不是空格。
此外,您的线路可能更简单一点:

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