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.
