I was wondering whether or not it is possible to use the NSCoder method: - (void)encodeObject:(id)objv forKey:(NSString *)key to encode either an instance of NSArray or NSDictionary.

Hi, i'm using the iphone sdk (3.0) and i'm trying to create an array of selectors to invoke a variety of methods within one class. Obviously, I'm doing something wrong (I think @selector isn't considered a class and so stuffing them into an NSArray isn't working). I tried this, but it's obviously wrong. Is there a simple way to have...

My strings are fine, but when they get added to an array a weird grouping of "\n\t\t" gets added to the end. So the string "Apple", becomes "Apple\n\t\t" when I look at the array description.

When I debug, I never get the value of an NSString inside of an array. All I see are cryptic symbols, probably memory addresses of something like 0x1dc3753. I dig into all the stuff and expand everything, but no humanly readable value at all. Not really useful at all. How do you go about this (besides NSLogging everything)? ...
