uiview - Adding actions to buttons in a subview -

-

in app call uiview , uiview settings screen in app , have buttons in uiview , question how add actions buttons iv added uiviews subview? thanks,

assuming you're writing code in view controller settings uiview, uiview bound view property of controller, , have referenced 1 of buttons variable button, here write:

- (void)viewdidload {     [super viewdidload];     [button addtarget:self                action:@selector(buttonpressed)      forcontrolevents:uicontroleventtouchupinside]; }  - (void)buttonpressed {     // things here in response button being pressed }

another way write method passing in pointer button pressed, so:

- (void)viewdidload {     [super viewdidload];     [button addtarget:self                action:@selector(buttonpressed:) // note colon here      forcontrolevents:uicontroleventtouchupinside]; }  - (void)buttonpressed:(id)sender {     uibutton *buttonwhichwaspressed = (uibutton *)sender;     // can things hide button, change text, etc. }

rather calling addtarget:action:forcontrolevents:, though, in interface builder (you should doing this) after defining buttonpressed or buttonpressed: method above, in .xib file button go second tab in inspector after clicking on button (it should button connections), , click-drag touch inside event file's owner, , select "buttonpressed" list.

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...
