Default Chap. 13 Try It Out Accessing the Videos in the Photo Library

Hi, there.
I'm trying to follow this "TRY IT OUT: Accessing the Videos in the Photo Library"
But, the sample code didn't work. :'(
I'm developing the application on iOS 4.2 (iPod touch 4th.)

I can pick my video, but it doesn't play back.
Please help me.

Thank you.

Default Chapter 13 - Photo and Video Library

I'm ok with the photo library working but when I get to the Try It Out for Access the Videos in the Photo Library I get a warning on this line:

NSArray *mediaTypes = [NSArray arrayWithObjects:kUTTypeImage, kUTTypeMovie, nil];
The warning is 'Passing argument 1 of 'arrayWithObjects:' from incompatible pointer...'

I get the same error when trying to run the sample code from the book. Haven't figured it out yet.

You have to cast the const CFStringRef to an NSString.

NSArray *mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage, //etc.
