How to share views using Xcode swipe gestures

Question

I use Xcode to develop a Cocoa touchscreen application for the iOS platform, but I'm having trouble finding how to implement a realistic gesture that allows the user to swipe left or right to switch to the new ViewController (nib / xib file). I did a swapView IBAction with a button and a modal transition, and I read about Apple TouchGestureRecognizer , but I don’t know how to implement a swipe action that will change the look.

I DO NOT want to use scrolling, since I have dozens of view controllers that I want the user to scroll through.

Here is an example:

First View Controller.xib: SwipeRight - transition to the second View Controller.xib

Second View Controller.xib:
SwipeLeft - Go to the first View Controller.xib
SwipeRight - transition to the third View Controller.xib

etc.

I have not used UISwipe / Touch Gestures before, but I used the 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]; } 

Does the napkin use a similar method, formatted differently? If so, how can I sort and format it.

thanks

Edit - answer as a comment on the question

Put it in your view

 UISwipeGestureRecognizer *swipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeftDetected:)]; swipeRecognizer.direction = UISwipeGestureRecognizerDirectionLeft; [self.view addGestureRecognizer:swipeRecognizer]; [swipeRecognizer release]; 

Then add a selector 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 another ViewView control that you change using

 #import "SecondViewController" 

at the top of your main file. Hope this helps.

Answer 1

This sounds like the perfect time to use the UIGestureRecognizer or, more specifically, the UISwipeGestureRecognizer .

For more information on how to use them, see the Gesture Recognition section of the Event Handbook.

Suppose you want to swipe left to open another view on the right.

In the storyboard, drag the gesture pointer. This will make the icon below the view controller; drag this icon and go to the ViewController you want to go to. This will add segue, select custom segue. Then create the 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]; }]; }
