How to swap views using a swipe gesture XCode - iphone

Question

I am using XCode to develop a Cocoa touch application for the iOS platform but have had trouble finding out how to get a swipe gesture implemented that would allow the user to swipe their finger left or right to change to a new ViewController (nib/xib file). I have done a swapView IBAction using a button and modal transitioning and I have read about Apple's TouchGestureRecognizer but I don't know how to implement a swipe action that would allow a view change.
I do NOT want to use a scroll view, as I have several dozen view controllers, that I want the user to be able to swipe through.
Here is an example:
First View Controller.xib:
SwipeRight- Go to second View Controller.xib
Second View Controller.xib:
SwipeLeft- Go to first View Controller.xib
SwipeRight- Go to third View Controller.xib
etc, etc
I have not used UISwipe/Touch Gestures before but I have used an IBAction method to switch views using a button with Modal Transitioning (see below):
-(IBAction)swapViews; {
SecondViewController *second2 =[[SecondViewController alloc initWithNibName:#"SecondViewController" bundle:nil];
second2.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:second2 animated:YES];
[second2 release];
}
Is using a swipe to do a similar method formatted differently? If so, how do I sort this out and format it.
Thank You
Edit - Answer as Per Comment on Question
Place this in your viewDidLoad
UISwipeGestureRecognizer *swipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(swipeLeftDetected:)];
swipeRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:swipeRecognizer];
[swipeRecognizer release];
Then add a selector as by pasting the following code into your main...
- (IBAction)swipeLeftDetected:(UIGestureRecognizer *)sender {
NC2ViewController *second2 =[[NC2ViewController alloc] initWithNibName:#"NC2ViewController" bundle:nil];
second2.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:second2 animated:YES];
[second2 release];
}
Then just make sure you import the otherViewController you are swapping to using
#import "SecondViewController"
at the top of your main file. Hope this helps.

This sounds like a perfect time to use UIGestureRecognizer or, more specifically, UISwipeGestureRecognizer.
For more info on how to use them, read up in the Gesture Recognizers section of the Event Handling Guide.

Lets assume you want to swipe left to bring up another view from the right.
In the storyboard, drag and drop a swipe gesture recognizer. It will make an icon below the view controller; drag this icon and drop onto the ViewController you want to navigate to. This will add a segue, select custom segue. Then create a UIStoryboardSegue class. Add the following code:
- (void)perform {
UIViewController* source = (UIViewController *)self.sourceViewController;
UIViewController* destination = (UIViewController *)self.destinationViewController;
CGRect sourceFrame = source.view.frame;
sourceFrame.origin.x = -sourceFrame.size.width;
CGRect destFrame = destination.view.frame;
destFrame.origin.x = destination.view.frame.size.width;
destination.view.frame = destFrame;
destFrame.origin.x = 0;
[source.view.superview addSubview:destination.view];
[UIView animateWithDuration:0.5
animations:^{
source.view.frame = sourceFrame;
destination.view.frame = destFrame;
}
completion:^(BOOL finished) {
UIWindow *window = source.view.window;
[window setRootViewController:destination];
}];
}
