  • splitting string:

    nsarray *parts = [string componentsseparatedbystring: @"~"];

  • assembling string array:

    nsstring *string = [parts componentsjoinedbystring: @" "];

  • sanitizing string, replacing occurences of ~ whitespace:

    nsstring *string = [string stringbyreplacingoccurrencesofstring: @"~"\                            withstring:@" " ]
