如何在UILabel.text中添加制表符空间 [英] how to add tab space into UILabel.text

问题描述

我有一个UILabel实例，比如mylabel。

I have a UILabel instance, say mylabel.

我想做的是这样的：

mylabel.text = @"Age\tLimit\tYear"; 

instead of  

mylabel.text = @"Age           Limit       Year";

但是当我尝试时，\t无法识别。如何实现呢？

But when i tried, \t is not recognized. How to achieve it?

推荐答案

您还可以先格式化字符串

You can also format string first

NSString *formattedString = [NSString stringWithFormat:@"Age%8s%8s",[@"Limit" UTF8String], [@"Year" UTF8String]];

mylabel.text = formattedString;

不幸的是，％@ formatter不会添加空格来调整字段宽度。
所以我使用带有％s说明符的UTF8String来调整宽度。

Unfortunately, %@ formatter doesn't add spaces to adjust field width. So I use UTF8String with %s specifier to adjust width.

注意：
Width指定要输出的最小字符数，通常是用于填充表格输出中的固定宽度字段，否则字段会更小，但不会导致超大字段的截断。

Note: Width specifies a minimum number of characters to output, and is typically used to pad fixed-width fields in tabulated output, where the fields would otherwise be smaller, although it does not cause truncation of oversized fields.
