回答1:

• Splitting a string:

  NSArray *parts = [string componentsSeparatedByString: @"~"];
  

• Assembling a string from an array:

  NSString *string = [parts componentsJoinedByString: @" "];
  

• Sanitizing a string, by replacing all occurences of ~ with whitespace:

  NSString *string = [string stringByReplacingOccurrencesOfString: @"~"\
                             withString:@" " ]
