Answer 1

I ran into the same issue and I think the valueForPasteboardType family of methods are broken and always return NSData. Here is my solution:

NSArray * lArrayFromPasteBoard = [pPasteBoard valueForPasteboardType:@"com.my.custom.type"];
if ([lArrayFromPasteBoard isKindOf:[NSData class]])
{
    lArrayFromPasteBoard = [[NSPropertyListSerialization propertyListWithData:(NSData*)lArrayFromPasteBoard options:0 format:0 error:0];
}

hopefully this will make it so the code in the if won't get called anymore once apple fixes their bug

Answer 2

As of iOS 8.3, UIPasteboard still has this bug. I wrote an extension for UIPasteboard to handle this:

extension UIPasteboard {
    func arrayForPasteboardType(pasteboardType: String) -> NSArray? {
        switch valueForPasteboardType(pasteboardType) {
        case let array as NSArray:
            return array
        case let data as NSData:
            if let array = NSPropertyListSerialization.propertyListWithData(data, options: 0, format: nil, error: nil) as? NSArray {
                return array
            }
        default:
            break
        }

        return nil
    }
}
