ios - How to prevent scrollview in UITableView when user swipe gesture down two touches? -

-

I think that when user swip direction is down on UITWV, I do some stuff and not scrolling the table is. How can I do this?

If you want your UISwipeGestureRecognizer UITableView's UIPanGestureRecognizer < With / code>, you just need to set up and implement a representative of your swipe gesture

- (BOOL) Gesture: Identifier: (UIGestureRecognizer *) The gesture must be recognized with synonymsistician : (UIGestureRecognizer *) otherGestureRecognizer

then return yes .

If you want to disrupt the tableview's pan gesture, you probably can not use the UISwipeGestureRecognizer to do this, since the user actually swiped a certain distance until it Not really.

If you need it, then maybe you can use a UIPanGestureRecognizer for counterfeit behavior. I was able to get something similar: 

  #pragma icon UIViewController lifecycle - (zero) viewDidoadload [[Super Viewedloadload]; UIPanGestureRecognizer * panner = [[UIPanGestureRecognizer alloc] initWithTarget: Auto Actions: @Selector (Dipan :)]; [Pager set deliget: self]; [Painter Setminman OffTouch: 2]; [Self-Televisions Ext Gesturerequiser: Pener]; } #pragma Custom Swipe Reaction Mark - (Zero) didSwipe {NSLog (@ "SWIPED!"); } #pragma mark UIPanGestureRecognizer response - (zero) didPan: (UIPanGestureRecognizer *) identifier {[self cancelGestureRecognizer: self.tableView.panGestureRecognizer]; If (recognizer.state == UIGestureRecognizerStateChanged) {CGPoint Translation = [Identifier Translation InView: self.view]; If (translate. Y> 20) {[self-naspeep]; [Self-cancellation: Protector: Identifier]; }}} #pragma mark UIGestureRecognzierDelegate implementation - (bool) gestureRecognizer: (UIGestureRecognizer *) gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer: (UIGestureRecognizer *) otherGestureRecognizer {// Note: returning yes blindly in this case is usually a bad idea. You should check the identifiers here. Yes come back } #pragma Icon UIGestureRecognizer The stuff that should be in a range and this file is not. - (empty) CancelTesterer: (UIGestureRecognizer *) identifier {if (recognizer.enabled) {[identifier set enabled: no]; [Enable identifier set: Yes]; He said, in most cases this makes it a better user experience to use only a pan gesture and to make any animation / transition / interaction based on the distance they have installed (). CGP translation is ).

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
