Objective-C右填充

问题描述

大家都希望有人可以提供帮助.我正在浏览网络，似乎没有任何意义:S

hello all hope someone can help with that. I was browsing the net and nothing really seems to make sense :S

所以我有一个字符串可以说:"123"，我想使用类似的功能:

so I have a string lets say:"123" and I would like to use a function like:

padr("123", 5, 'x')

，结果应为:

"123xx"

对不起，但是Objective-C是处理字符串:S

Sorry but Objective-C is a nightmare when dealing with strings :S

推荐答案

您可以创建自己的方法来获取初始字符串，所需的长度和填充字符(正如我刚开始做的&在其他类似文章中所描述的)问题)

You could create your own method to take the initial string, desired length, and padding character (as I was starting to do & also described in a few similar questions)

或者您可以使用Apple已经提供的NSString方法;)

Or you could use the NSString method Apple already provides ;)

NSString *paddedString = [@"123" 
                           stringByPaddingToLength: 5 
                           withString: @"x" startingAtIndex:0];

请参见此方法的NSString类参考.
