Custom transition between viewcontrollers holding tableviews. Each cell is animated to simulate a 'wave effect'.

- Add
pod 'AMWaveTransition'to your Podfile - Run
pod install - Run
open App.xcworkspace
github "andreamazz/AMWaveTransition"
- Subclass
AMWaveViewControllerand overridevisibleCellsor follow these steps:
Implement UINavigationControllerDelegate and this delegate method:
- (id<UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController
animationControllerForOperation:(UINavigationControllerOperation)operation
fromViewController:(UIViewController*)fromVC
toViewController:(UIViewController*)toVC {
if (operation != UINavigationControllerOperationNone) {
// Return your preferred transition operation
return [AMWaveTransition transitionWithOperation:operation];
}
return nil;
}Remember to set your instance as the navigation delegate:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self.navigationController setDelegate:self];
}
- (void)dealloc {
[self.navigationController setDelegate:nil];
}Implement th AMWaveTransitioning protocol by returning your tableview's visible cells:
- (NSArray*)visibleCells {
return [self.tableView visibleCells];
}To implement the interactive gesture create a new property in your view controller:
@property (strong, nonatomic) IBOutlet AMWaveTransition *interactive;initialize it in your viewDidLoad:
self.interactive = [[AMWaveTransition alloc] init];Attach the gesture recognizer in your viewDidAppear: and detach it in the viewDidDisappear::
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self.interactive attachInteractiveGestureToNavigationController:self.navigationController];
}
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
[self.interactive detachInteractiveGesture];
}If the view controller you are transitioning to has no table view, don't implement visibleCells, the library will handle the transition correctly.
As you can see in the sample project, the best results are obtained by setting the view and the cells' background to clearColor, and setting a background color or a background image to the navigation controller.
