Remove Whitespace from NSString

In Cocoa Touch you always need to write more to achieve the same …

NSString *string = @" spaces in front and at the end ";
NSString *trimmedString = [string stringByTrimmingCharactersInSet:
                                  [NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSLog(trimmedString)

While such a standard task might look excessively much code to write, you gain many additional possibilites of what you could want to trim away. NSCharacterSet also knows these other sets. 

• alphanumericCharacterSet
• capitalizedLetterCharacterSet
• controlCharacterSet
• decimalDigitCharacterSet
• decomposableCharacterSet
• illegalCharacterSet
• letterCharacterSet
• lowercaseLetterCharacterSet
• newlineCharacterSet
• nonBaseCharacterSet
• punctuationCharacterSet
• symbolCharacterSet
• uppercaseLetterCharacterSet
• whitespaceAndNewlineCharacterSet
• whitespaceCharacterSet
