how to override UIView.pointInside in swift? -


i'm trying port code obj-c swift, experienced lot of troubles.

one of issues overriding pointinside of uiview class:

class myview : uiview{ func pointinside(point: cgpoint, withevent event: uievent) -> bool {     if point.x < 0 {         return false     } else {         return true      } }}

if don't add "override", error:

/xxx.swift:37:10: method 'pointinside(_:withevent:)' objective-c selector 'pointinside:withevent:' conflicts method 'pointinside(_:withevent:)' superclass 'uiview' same objective-c selector

if add "override", error:

/xxx.swift:37:19: method not override method superclass

according doc, there should pointinside function

https://developer.apple.com/library/ios/documentation/uikit/reference/uiview_class/#//apple_ref/occ/instm/uiview/pointinside:withevent:

the function in uikit declared as

func pointinside(_ point: cgpoint, withevent event: uievent?) -> bool

the optionality (namely uievent?) needs match.

this error message seems less useful; might want file bug.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
