Views Navigation Using Swipe Gesture

Question

How can I switch views vertically using swipe gestures ?

Answer 1

Certainly! Just set your viewController to be the UIGestureRecognizerDelegate and declare UISwipeGestureRecognizer *swipeLeftRecognizer; (also retain and synthesize). Then, in the implementation, set up the recognizers with

    UIGestureRecognizer *recognizer;
    // RIGHT SWIPE
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self 
                                                           action:@selector(handleSwipeFrom:)];
    [self.view addGestureRecognizer:recognizer];
    [recognizer release];
    // LEFT SWIPE
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
    self.swipeLeftRecognizer = (UISwipeGestureRecognizer *)recognizer;
swipeLeftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.view addGestureRecognizer:swipeLeftRecognizer];
self.swipeLeftRecognizer = (UISwipeGestureRecognizer *)recognizer;
    [recognizer release];

Then trigger the actions you want with the method

- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
    if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft) {
        // load a different viewController
    } else {
        // load an even different viewController
    }
}

What you do here is specific to your app. You can switch the tabBar selection, jump through a navigationController, present a different view modally, or just do a simple slide in transition.
