How to make swipe animation on blackberry.
When i swipe the screen, the next information will be shown.
Any sample code is there.?
Edit:
How about this:

I've got a view on the bottom of my ViewController ( similar to Google Maps Bottom Sheet ). The goal is:
When panning up, the view moves towards the pan direction ( essentially follows the finger), when panning ends, the view goes fullscreen. So far so good, all works.
Adding swipe gestures. When swiping up, the view should go full screen.
The issue is that by definition, a swiping gesture is a pan gesture but not the other way around. So unless i go really slow with my panning , the swipe gesture will trigger and the view will go full screen even though im still dragging on the screen.
Simply panning up doesnt look much like the kind of swipe im looking for. The swipe gesture im describing should only trigger if the user "flicked" the view momentarily. If they keep on panning the pan gesture should take precedence.
Any ideas how to achieve this? For reference you could check tap on a pin on google maps on either android or ios.
Its a little hard to describe without showing so if it helps im very open to clarify things.
UPDATES
I think the distinction for a swipe that would override the pan as im describing is that it a) took a short amount of time to complete b)the gesture ended with the user lifting the finger off the screen c) (maybe wrong ) the area traversed should not be too big. Sounds a lot like a flick to me..
If you cannot describe the difference between the two gestures in clearly defined terms then it will be difficult to tell the UIGestureRecognizer how to do so. In addition, it is possible that your user will have difficulty figuring out how to properly interact with the screen if your gestures are too similar or complex.
That being said, you may be able to distinguish between a "swipe" and a "pan" by checking the gesture's velocity. You should be able to play around with the UIGestureRecognizerDelegate methods and achieve the effect you want.
Ok i've achieved what was needed. The short answer is that i was looking for a "flick" gesture instead of a pan gesture. Generally its a nono to add custom gestures but as im replicating the google maps bottom sheet component for ios, it would appear that a custom gesture is the only way.
Using Navillus's comment, I added a velocity and gesture end check in the pan recogniser. The result looked like this:
if(recognizer.state == .ended){
if(recognizer.velocity(in: self).y > CGFloat(500) ){
self.pullUpViewSetMode_SUMMARY()
return;
}
if(recognizer.velocity(in: self).y < CGFloat(-500) ){
self.pullUpViewSetMode_FULL()
return;
}
}
//the rest of the pan handling code, namely translating the view up and up follows here
Hope this helps somebody.
Hi All,
I need to achieve partial swipe left to view button on right side.
I tried multiple solutions found here and official forum but all the resulting in tap action being triggered on the row.
None of them resulted in partial left swipe.
any idea how to achieve it ?
Thanks in advance
From what I understand you might performing this swipe with end point located around that button/row you try to make visible?
If e.g. this row with a button is located lets say between 45%-50% of the height of the screen you need to perform this swipe below or above it on the background to not interact with the element itself during the swipe action which is a touch and move to action after all.
I know how to add UIPreviewActionItem when swipe from the bottom. There is a method previewActionItems(). But how to do the following thing:
Left and right swipe is a custom implementation by Apple engineers. Broke my heart when I found that out as well.
As Apple's documentation says:
Provide peek quick actions, if appropriate. Within a peek, users can swipe up to reveal actions that are related to the item.
There is nothing about left/right swipe.
In my iPad project i have to make
1.Tap gesture
2.Swipe right and Swipe left Gesture
3.Single Finger Pan Gesture
4.Two finger Pan gesture.
5.Long press gesture
I don't know how to handle all these gestures.When Long press gesture is used only Swipe right gesture and two finger Pan gesture has to work. App gets confused at these many gestures in a single screen. How to Handle everything easily. Please help
Firstly i will say your question was little confusing and we can easily add multiple UITapGestures on a singleView without any prob. The OS automatically detects which gestures you are doing. There are many tutorials for that. Look at these links, if you still can find any solution, tell me may be i can try a code piece for u.

I'm trying to figure out how to detect a press and hold, as well as a gesture recognizer on a UIButton.
I did search around and didn't find exactly what I was looking for.
Here is a quick gif to see what I'm trying to do: http://blitzzmobile.com/files/button.gif
(in the case of the gif the user holds on the "5" button and drags up to select the addition button.)
If anyone could give me a tip or point me in the right direction it would be greatly appreciated!
Edit : Also, I'd like to know if its possible to detect the location of the "drag" and animate accordingly. (Example: if someone drags half the distance to show the new menu, the menu animates accordingly) & the method to detect the drag release, not from the UIButton, but when the user lifts his finger after touching the UIButton and dragging, an action is called, is this possible?
For whoever might benefit from this, here is what I did:
-(IBAction) yourAction:(UISwipeGestureRecognizer *)recognizer{
if(yourbutton.highlighted){
//Do your animation/setup here.
}
}
