I’m using a NSMutableArray to hold a bunch of Integers for a program Cocoa-Java, so I can save and reload them easily enough using NSUserDefaults.

I’m putting Integers into the Array, the .plist describes an array of s, but when I try to cast any object which I pull out of the Array with NSArray.objectAtIndex(int index) back to an Integer I get a ClassCastException thrown.

Now here’s the really strange part: the exception message tells me that the object is a Long, not an Integer. As an experiment, I tried casting the Object to a Long, to the same effect, except the exception message reckons I should be casting to an Integer!

Cast it to a Number and run intValue() on it. –TheoHultberg/Iconara
