ipad - UITableView does not respond to scrolling and touches -

-

i've created custom uiview, , inside uiview, add uitableview thus:

    treeview = [[uitableview alloc] initwithframe:cgrectmake(0, 80, slider.frame.size.width, slider.frame.size.height - 80)];     [treeview setdelegate:self];     [treeview setdatasource:self];     [self addsubview:treeview];     [treeview release];

when app loads, table seems load fine. however, when try scroll table, not respond touches @ all.

i implement these delegate/data source methods:

- (nsinteger)numberofsectionsintableview:(uitableview *)tableview; - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section; - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath; - (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath;

does have idea why so?

thanks

there several possibilities:

  • your custom view, or 1 of superviews, has userinteractionenabled set no.
  • there view on top of custom view, or on top of table view within custom view.
  • the custom view table view inside smaller table view (with clipstobounds=no, subview extends beyond bounds of parent can seen not interacted with). or same view in stack.
  • the custom view (or 1 of superviews) overrides pointinside:withevent: or hittest:withevent: incorrectly.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
