when I have time I will be back to read a lot more, Please do keep up the
great b.

To be honest, I've not used

To be honest, I've not used storyboards at all, because all of my work still targets iOS 4.x. In fact, my two applications don't even use Interface Builder at all. Therefore, I'm not the person to ask about this.

If you were able to describe and preferably diagram what you want to do, this would make for a good question to ask on Stack Overflow.

Hello Brad, I have downloaded

Hello Brad,

I have downloaded and watched your advanced iOS development course via iTunesU and I have a question. I am working on my frist app and I have yet to find a site/person that can give me an answer

I am using Xcode 4.3.3 with storyboards and I am trying to figure out how to embed videos on the detail split of some of the different views. I am writing an educational app and I have users selecting lessons in the master split on the left, which pulls up a segue that pushes the new lesson into the detail view on the right and each lesson has a video that goes along with it. I have found examples on how to just create a "play movie" button but that's not what I'm looking to do, I would rather it look like if you visited a website and saw the video with a frame waiting to play.

Any suggestions?

That's what happens when the

That's what happens when the CALayer's coordinate system gets inverted. "Top" was defined as being the top of the layer under the Quartz coordinate system, so when UIViews invert their backing layer, this gets flipped as well.

UIView's main layer's

UIView's main layer's coordinate system gets flipped to make the origin point x:0,y:0 at TOP-LEFT corner. When you add an image directly to the layer's contents and set gravity to top, like this:

myView.layer.contents = [[UIImage imageNamed:@"ball.png"] CGImage];
myView.layer.contentsGravity = kCAGravityTop;

ball appears in the bottom. Is it an intentional inconsistency?

Ok, now I can see Block

Ok, now I can see Block section. Thank you very much for your support. Have a nice day. Regards, Lorenzo.

Did you get the class notes

Did you get the class notes for the fall semester? The ones for the spring semester didn't have anything with blocks in them. My notes here for the fall semester have the bit on blocks at the very bottom of the Understanding Cocoa section. There's also a bit on blocks in the Multithreading section, in regards to their use in GCD.

Thank you for your reply.

Thank you for your reply. I've already downloaded course notes, but I can't see Blocks section on Understanding Cocoa note. On the contrary, in the relative video it's possible to see the note for this argument. Thank you very much. Regards.

The class notes are linked to

The class notes are linked to on the left-hand side in iTunes U, and can be found here.

Thanks for sharing these

Thanks for sharing these videos. They are absolutely fantastic!!

P.S. I've just watched the second one, Understanding Cocoa, but I didin't find VoodooPad notes about Blocks and Handling multiple OS and device versions.
