how to get rid of heading and trailing white spaces from NSString
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开发者_开发百科 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
How about stringByTrimmingCharactersInSet: method? By stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet], it can remove both ends of whitespace and newline characters.
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.
