I have a horizontal swipe of my UIPageViewController that moves between 3 view controllers. I want to add a Vertical swipe onto this to add a extra level to the navigation.
However I have not found a solution to do so. I have tried adding a simple
UISwipeGestureRecognizer *gestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(swipeHandler:)];
[gestureRecognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];
[self.view addGestureRecognizer:gestureRecognizer];
But this doesn't work as I presume the UIPageView overrides this.
Is there any solution?
If you are doing with storyboards,this tutorial would be helpful
http://www.appcoda.com/uipageviewcontroller-storyboard-tutorial/
I am using pageview controller in my app. I have added same code as yours. and my swipe up event is working fine.
change this line in your code
[gestureRecognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];

I want to implement a custom notification over to be shown from with in my app. It should show a message and allow user to swipe down to reveal couple of buttons for action. I am supporting minimum iOS 6.
By far, I am able to create a custom view subclassing UIView and put up message in it. How do I implement the feature of swipe down to reveal couple of buttons?
Any references would be helpful.
Try with this:
UISwipeGestureRecognizer *gestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(swipeHandler:)];
[gestureRecognizer setDirection:(UISwipeGestureRecognizerDirectionDown)];
[self.view addGestureRecognizer:gestureRecognizer];
-(void)swipeHandler:(UISwipeGestureRecognizer *)recognizer {
NSLog(#"Swipe received.");
}
Add a UIView below your notifications that will have a height of 0 and on swipe down, increase the height of that particular constraint.
I've been looking for solution for this question,but didnt find any one. So I use SWRevealViewController for sidebar menu in my project but I want that side menu would open when user beging to touch from left edge of the view. I want this because I have another swipeGestureRecognizer for left and right swipe.For adding left and right swipes I'm use this code:
UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:#selector(swipedToRight:)];
swipeRight.direction = UISwipeGestureRecognizerDirectionRight;
UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget: self action: #selector(swipedToLeft:)];
swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
So my question is how can I make that side menu would open only when touches begins from left edge?
UPD 1
I use this code to open side menu by panning at any part of the screen
[self.view addGestureRecognizer: self.revealViewController.panGestureRecognizer];
And I have recognizer to swipe to right. The problem is once it open menu and once executes swipe's action. I want to allow to open menu only when touches is from left edge
UPD 2 Solved
I solved it by setting draggable border width:
self.revealViewController.draggableBorderWidth = self.view.frame.size.width / 2;
And now gesture from edge to center opens menu, and from center to right border executes swipe's action
What I would do is modify the already existent pop gesture that is built into the UINavigationController class.
You can add a UIPanGestureRecognizer as you mentioned before or add a subView in the top of your view and add a gesture to it:
UIView *topView = ...
[self.view addSubview: topView];
UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc]
initWithTarget:self action:#selector(didPan:)];
[topView addGestureRecognizer:pan];
What I would do is modify the already existent pop gesture that is built into the UINavigationController class.
Example code to add to your viewWillAppear:
if ([self.navigationController respondsToSelector:#selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
// Your code here
}
My collection view is working great. It shows a grid of photos and lists hundreds of them. You can swipe vertically to scroll through them all. Life is good. However, I now have a new requirement. I need to be able to detect when the user is swiping left or right. I need to be able to intercept this gesture so I can attach behavior to left and right swipes while keeping intact my collection view's vertical scroll capabilities. Any ideas?
You need two recognizers, one for swiping left, and the other for swiping right:
UISwipeGestureRecognizer* swipeUpGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(handleSwipeLeftFrom:)];
swipeUpGestureRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
and for the handler:
- (void)handleSwipeLeftFrom:(UIGestureRecognizer*)recognizer {
}
Finally, you add it to your view:
[view addGestureRecognizer:swipeUpGestureRecognizer];
The same for the other direction (just change all the Lefts to Rights).
add UISwipeGestureRecognizer to the cells settings its direction as below,
UISwipeGestureRecognizer *swipeRightDir = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(didSwipeRightDirection:)];
swipeRightDir.delegate = self;
swipeRightDir.numberOfTouchesRequired = 1;
[swipeRightDir setDirection:UISwipeGestureRecognizerDirectionRight];
I am developing an app and I want to scroll through different UIViewControllers with a UISwipeGestureRecognizer.
Everything works, but there is one thing where I couldn't find a solution for.
I add the UIGestureRecognizers like this
- (void)viewDidLoad {
[super viewDidLoad];
UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(swipeLeft)];
[swipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
[self.view addGestureRecognizer:swipeLeft];
UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(swipeRight)];
[swipeRight setDirection:UISwipeGestureRecognizerDirectionRight];
[self.view addGestureRecognizer:swipeRight];
}
Now I want to know if it is possible to except a part of the self.view where it is possible to swipe to a different view.
I want to do this around a UISwitch.
Can someone please help me?
Best regards,

You can use another UIView and add it to self.view. Those UISwipeGestureRecognizer won't work inside that UIView.
Add another UISwipeGestureRecognizer to the switch, and, on your original swipe gesture recognisers, call requireGestureRecognizerToFail: on the switch's new recognizer.
Hope that makes sense, it's such a verbose class... :\
I suggest you to use the delegate method of a gesture recognizer : gestureRecognizer:shouldReceiveTouch:.
In the touch parameter, you have many information, like the position in the screen. You can use this position and test if it is above the switch frame. Return yes or no depending of if you want to trigger the selector associated to the gesture recognizer or not.
I am creating a storyboard app where the view is changed when the user performs swipe gestures. The issue I am having is that when you drag and drop a gesture recognizer onto the view from themain.storyboard file, the gesture is recognized from anywhere inside the UIView. Basically, I need to recognize a gesture that is performed in a specific area on the screen, similar to how you drag down the notification center in IOS 6. If this is unclear or you need more details, feel free to ask.
Thanks in advance for any help!
I am not sure if this will help you or you tried something like this, but i want to share my idea.
You can try UISwipeGestureRecognizer in your ViewControl.m like below:
UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(swipeToDoMethod)];
[swipeGesture setDirection:UISwipeGestureRecognizerDirectionRight];
[[self innerView] addGestureRecognizer: swipeGesture];
You can add an inner view into your main view and add this gesture to that view.
Hope this helps you, good luck! :)
UISwipeGestureRecognizer *swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(SwipeView)];
[swipe setDirection:UISwipeGestureRecognizerDirectionLeft];
[[self innerView] addGestureRecognizer: swipe];
//UISwipeGestureRecognizerDirectionRight (or) up (or) down
Use another UIView with 0 visibility, put it on area where you want recognize a gesture and then add gesture to this UIView.
This is just an idea.
Hope this will help you.
You can add a subview into your view, set the subview's frame to the area where you want to catch the swipe gesture, add recognizer to it, and set its background color to clear color. Hope it help.
Adding Swift version:
//Add gesture recognizer
let swipeGesture = UISwipeGestureRecognizer(target: self, action: #selector(dismissShowMessageAndButtonDueToSwipeUp))
swipeGesture.direction = .up
backgroundView.addGestureRecognizer(swipeGesture)
