如何从NSString中删除标题和尾随空格 [英] how to get rid of heading and trailing white spaces from NSString

问题描述

我的NSString是这样的：

My NSString is like this:

NSString *myString =  
(  
"\n \n 24 K CLUB",  
"\n \n 3 DOLLAR CAFE",  
"\n \n A PEACH OF A PARTY",  
"\n \n A ROYAL AFFAIR CAFE",  
"\n \n AFFAIRS TO REMEMBER CATERERS",  
"\n \n AFRIKAN DELI"  )

如何摆脱这个新行字符和空格，以便我的新字符串如下：
newString：

How to get rid of this new line character and white spaces, so that my new string will be like: newString:

(
"24 K CLUB",  
"3 DOLLAR CAFE",  
"A PEACH OF A PARTY",  
"A ROYAL AFFAIR CAFE",  
"AFFAIRS TO REMEMBER CATERERS",  
"AFRIKAN DELI" 
) 

我试过：

myString = [myString stringByReplacingstringByReplacingOccurrencesOfString:@"\n" withString:@""];  
myString = [myString stringByReplacingstringByReplacingOccurrencesOfString:@" " withString:@""];

但未成功..出现错误：

but unsuccessfully..getting error:

[__NSArrayI stringByReplacingOccurrencesOfString:withString:]: unrecognized selector sent to instance 0x7062200

推荐答案

怎么样 stringByTrimmingCharactersInSet：方法？
通过 stringByTrimmingCharactersInSet：[NSCharacterSet whitespaceAndNewlineCharacterSet] ，它可以删除空格和换行符的两端。

How about stringByTrimmingCharactersInSet: method? By stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet], it can remove both ends of whitespace and newline characters.
