Scenes

Aliquando invenimus talem missionem interactive: UITableView habemus
Pone eam in fenestra pop-up. Haec fenestra pop-up lapsus ostendi potest et evanescit (swiping manu tua). Productum informationem et commentarium (similis commentarii Douyin in fenestra pop-up), et cum delapsus est, si tableView ad summum delapsus est, gestu lapso respondere potes et per fenestram pop-up deorsum labi.

Ideae

Primum, tabula View in sententia pop-up habemus. Haec tableView normaliter labi potest. Tum gestus inclinatus ad sententiam pop-upi addimus fenestra.Propterea, haec sententia pop- sursum est procuratorem qui gestibus respondet
quadrata et in

  • (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *) otherGestureRecognizer
    In proxy methodo, si gestu Recognizer est suus gestus lapsus et alius Gesture Recognitor est lapsus gestus tabulae View, oportet simul responsionem sustinere, id est, reverti ETIAM our
    Cum tabulae tabulae ad summitatem spectant, necesse est ut librum gestum tablView ad responsionem non sustineat. Alioquin tabulaView in librum perget cum ad summum librum causa pop-ups et tableView In casu simultanei scrolling, hoc est quod nolumus, ergo cum tablView libri ad summum, necesse est ut tabulae View pangesture.enabled = NO.

Dual ungunt gestu volumen responsionis mechanism

Gestum inclinatum ad fenestram pop-up addimus, et responsionis methodus tractabilis est:
Per probationem invenimus quodCum cartis manu nostra in tableView, quotiescunque exequimur
Ante tabulam View ineundo methodum scrollViewDidScroll, modus manubrii exsecutus est.

Quaeso addere imaginem descriptionem

Quin etiam in ungunt (idem ungunt, si velum manus non relinquit);
Si positum est in modum responsionis handlePan
self.tableView.panGestureRecognizer.enabled = NO;
self.tableView librum non vult in hoc lapsu, etiam si self.tableView.panGestureRecognizer.enabled = ETIAM ponitur post self.tableView.panGestureRecognizer.enabled = NO, librum non habebit.

Hoc ostendit, quod gestum in responsione ad illapsum, self.tableView.panGestureRecognizer.enabled = NO summam prioritatem habet.
