how to get rid of heading and trailing white spaces from NSString

Question

My NSString is:

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” )

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” )

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

but unsuccessfully..getting error:
[__NSArrayI stringByReplacingOccurrencesOfString:withString:]: unrecognized selector sent to instance 0x7062200

Answer 1

Your initial declaration of myString is declaring an NSArray, not a NSString. Your calls to stringByReplacingstringByReplacingOccurrencesOfString: withString: should work on the individual NSStrings. Either iterate the array yourself (see here) to trim the strings, or use makeObjectsPerformSelector: (see here) to handle it.

Answer 2

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