objective c - How can I access the property in an object that has an unknown class? -

-

my initial code was

[[[show episodes] lastobject] setdescription:nodecontent];

this gets last object episodes array , tries set episode's description property using nodecontent. not work because think compiler not know class of episode object.

i tried providing cast

((episoderepresentation *)[[show episodes] lastobject]).description = nodecontent;

this doesn't work either. have tried unsuccessfully

episoderepresentation *rep = [[show episodes] lastobject]; rep.description = nodecontent;

all these ways leave description null (nodecontent not null, nsstring).

your array empty. try [[show episodes] count] number of objects in array.

btw: naming of classes , methods seems odd. classes begin captal letters , methods lower case letters.
