NSString remove whitespace characters-include trim on both sides of the character ()

Remove spaces:

NSString *cleanstring = [dirtystring stringbytrimmingcharactersinset:[nscharacterset Whitespaceandnewlinecharacterset]];

There is also the removal of more than the space, as follows:

NSString *thestring = @ "Hello This is a long string! ";

Nscharacterset *whitespaces = [Nscharacterset whitespacecharacterset];
Nspredicate *noemptystrings = [nspredicate predicatewithformat:@ "Self! ="];

Nsarray *parts = [TheString componentsseparatedbycharactersinset:whitespaces];
Nsarray *filteredarray = [parts filteredarrayusingpredicate:noemptystrings];
TheString = [Filteredarray componentsjoinedbystring:@ ""];
NSLog (@ "%@", thestring);
