Trim string from END

Question

I want to string string from the end of string, is there any api function of string which ONLY removes Space and Newline from END of string.

I wrote manual code to search character from end of string and remove space and newline but it may slow the process.

API function needed..

Thanks in advance

Does your string have spaces in-between words? `hello hello ` vs `hello `? — nattyddubbs, Mar 14 '13 at 12:51
@nattyddubbs , yes my string is containing space and newline in words, its kind of big sentence but I want to remove space and newline from the end only. — Ajay_Kumar, Mar 14 '13 at 12:53

try this one may be it helps you,

-(NSString *)removeEndSpaceFrom:(NSString *)strtoremove{
    NSUInteger location = 0;
    unichar charBuffer[[strtoremove length]];
    [strtoremove getCharacters:charBuffer];
    int i = 0;
    for ( i = [strtoremove length]; i >0; i--){
        if (![[NSCharacterSet whitespaceCharacterSet] characterIsMember:charBuffer[i - 1]]){
            break;
        }
    }
    return  [strtoremove substringWithRange:NSMakeRange(location, i  - location)];
}

and

 NSString *string = @"          this text has spaces before and after         ";
    NSString *trimmedString = [self removeEndSpaceFrom:string];
    NSLog(@"%@",trimmedString);

Trim string from END
