3. UINavigationController

5. ViewController *c = [[ViewController alloc]
initWithNibName:@"ViewController"
bundle:nil];
UINavigationController *nc =
[[UINavigationController alloc]
initWithRootViewController:self.viewController];

6. - (IBAction)buttonTapped
{
UIViewController *c =
[[SubViewController alloc]
initWithNibName:@"SubViewController"
bundle:nil];
[self.navigationController pushViewController:c
animated:YES];
}

7. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:
(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil
bundle:nibBundleOrNil];
if (self)
{
self.title = @"ViewController";
}
return self;
}

9. UITabBarController

initWithNibName:@"ViewController"
bundle:nil];
SubViewController *s = [[SubViewController alloc]
initWithNibName:@"SubViewController"
bundle:nil];
UITabBarController *tc = [[UITabBarController alloc] init];
tc.viewControllers = [NSArray arrayWithObjects:c, s, nil];

12. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:
(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil
bundle:nibBundleOrNil];
if (self)

24. UIGestureRecognizer
UIView:
- (void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer

25. UITapGestureRecognizer
UITapGestureRecognizer *t = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:@selector(tapped)];
t.numberOfTapsRequired = 1;
t.numberOfTouchesRequired = 1;
[self.view addGestureRecognizer:t];

26. UIPanGestureRecognizer
UIPanGestureRecognizer *p = [[UIPanGestureRecognizer alloc]
initWithTarget:self
action:@selector(pan:)];
[self.view addGestureRecognizer:p];
- (void)pan:(UIPanGestureRecognizer *)sender
{
CGPoint t = [sender translationInView:self.view];
CGPoint v = [sender velocityInView:self.view];
NSLog(@"%@", NSStringFromCGPoint(t));
NSLog(@"%@", NSStringFromCGPoint(v));
}

27. UIPinchGestureRecognizer
UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc]
initWithTarget:self
action:@selector(pinch:)];
[self.view addGestureRecognizer:pinch];
- (void)pinch:(UIPinchGestureRecognizer *)sender
{
CGFloat scale = sender.scale;
NSLog(@"%g", scale);
}

28. UIRotationGestureRecognizer
UIRotationGestureRecognizer *r = [[UIRotationGestureRecognizer alloc]
initWithTarget:self
action:@selector(rotate:)];
[self.view addGestureRecognizer:r];
- (void)rotate:(UIRotationGestureRecognizer *)sender
{
CGFloat r = sender.rotation;
NSLog(@"%g", r);
}

29. UISwipeGestureRecognizer *s = [[UISwipeGestureRecognizer alloc]
initWithTarget:self
action:@selector(pan:)];
s.direction = UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:s];
• UISwipeGestureRecognizer
• UILongPressGestureRecognizer
UILongPressGestureRecognizer *p = [[UISwipeGestureRecognizer alloc]
initWithTarget:self
action:@selector(pan:)];
p.minimumPressDuration = 0.5;
[self.view addGestureRecognizer:p];

30. UIGestureRecognizerDelegate
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer;
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
shouldRecognizeSimultaneouslyWithGestureRecognizer:
(UIGestureRecognizer *)otherGestureRecognizer;
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
shouldReceiveTouch:(UITouch *)touch;

31. UIGestureRecognizerState
typedef enum {
UIGestureRecognizerStatePossible,
UIGestureRecognizerStateBegan,
UIGestureRecognizerStateChanged,
UIGestureRecognizerStateEnded,
UIGestureRecognizerStateCancelled,
UIGestureRecognizerStateFailed,
UIGestureRecognizerStateRecognized =
UIGestureRecognizerStateEnded
} UIGestureRecognizerState;
