Reference Counting (arc).
@ for NSLiteral, so that "" doesn't mean C-string.


Set tableView delegate and dataSource = self.
Set numberOfRowsInSection
Set cell


Use a navigation controller, to use the movies view controller, and set the root view controller as the new navigation controller.

TableView does not load all the contents of all the rows at once. It sets them up on a need-to-use basis. It kicks out the contents of cells not being seen.

Create a subclass of TableViewCell, MovieCell. Set labels, set 0 as the number of lines in the summary label.

Now, back to MoviesViewController. 
self.tableView registerNib:[UINib:nibWithNibName:@"" for CellReuseIdentifier@"MovieCell". In cellForRowAtIndexPath [tableView dequeueReusableCellWithIdentifier:@"MovieCell"]

In viewDidLoad, create an NSURL *url. Also, create a request:
NSURL *req = [[NSURLRequest alloc] initWithURL:url];
[NSURlConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:(..) {
  NSDictionary *responseDictionary = [NSJSONSerialization JSONOb
  
  self.movies = responseDictionary[@"movies"]
  
No NPE in ObjC :-| nil.size returns 0.


Set the title and synopsis, and reloadData.

Tip: Don't name your outlet of an Image View as 'imageView'. That will clash with the TableView. Now, get the url. 

ObjC: [movie valueForKeyPath:@"posters.thumbnail"]; // Nested access of keying in a dictionary.
Use CocoaPod, set up AFNetworking

ObjC: can add methods even after class has been declared.

#import "UIImageView+AFNetworking.h"
[cell.posterView setImageWithURL] <= Not a part of CocoaTouch, its in AFNetworking.


XCode: key-value coding compliant => missing connection.
XCode: NSRangeException Set exception handler.

tableView didSelectRowAtIndexPath to do some work around. 
pushViewController to get to the detail view controller.

ScrollViews are dumb. You need to tell them how big is your text. TableView is derived from ScrollView. You can set the scroll size. Parallax view => register callbacks.
