* Creating a view in Code

- (void)loadView{

MyView *myView = [[MyView alloc] initWithFrame:frame];

self.view = myView;

[myView release];

}

* View controller lifecycle

- (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)bundle { }

- (void)viewDidLoad {}

- (void)viewWillAppear:(BOOL)animated {}

- (void)viewWillDisappear:(BOOL)animated {}

* Loading & Saving data

NSUserDefaults

Property lists

SQLite

Web services

* Supporting interface rotation

- (void)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

return (interfaceOrientation == UIInterfaceOrientationPortrait);

// This view controller only supports portrait.

// retrun (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);

// This view controller supports all orientations except for upside-down.

}

* Autoresizing your views

view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;
