Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
type hinting in objective-C??
Hi, recently I accept a job requires using PHP PDO, I am not so comfatable with PDO yet so I did some research I found this regarding classes and interface.
1.) All classes that implement an interface must develop all the methods that have been defined
2.) The class implementing the interface must use the exact same method signatures as are defined in the interface. Not doing so will result in a fatal error
3.) All methods declared in an interface must be public, this is the nature of an interface
4.) A class can implement more than one interface
5.) An interface can be used by the Type Hinting
The first 4 points seem to apply to Objective-C, but point 5 got me curious,
is there Type Hinting in Obj-C as well?
thanks.
