如何从NSString中删除标题和尾随空格

Question

我的NSString是这样的:

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:

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

我试过了 :

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

但没有成功..忘记错误:

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

如何stringByTrimmingCharactersInSet:方法？通过stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet],它可以删除空白和换行符的两端.
