iphone - Setting Property on UIButton in Loop -

-

i'm spinning in circles on best way implement this, maybe can me out:

how can make when uibutton responds selector highlightimage, can set desired challengeid = index of appdelegate.availablearray?

in cellforrowatindexpath method, i'm creating uiscrollview buttons:

scrollview = [[uiscrollview alloc] initwithframe:cgrectmake(0, 0, tv.frame.size.width, 78)];     [scrollview setcontentsize:cgsizemake(500, 78)];      [self createscrollbuttons];      [[cell contentview] addsubview:scrollview];

my createscrollbuttons loops , creates buttons in scrollview so, looping on number of elements in availablearray

- (void) createscrollbuttons {     superherogameappdelegate *appdelegate = (superherogameappdelegate *)[[uiapplication sharedapplication] delegate];      int x = 0;     int y = 0;     nslog(@"challenge array = %@",appdelegate.availablearray);     (int = 0; < [appdelegate.availablearray count]; i++) {         nslog(@" id= %d", [[[appdelegate.availablearray objectatindex:i]valueforkey:@"id"] intvalue]);         [self createbuttonatx:x andy:y withchallenge:[[appdelegate.availablearray objectatindex:i]valueforkey:@"id"]];         x += 90;     }  }

createbuttonatx andy withchallenge called each element inavailablearray`, positioning them correctly along scrollview.

- (void)createbuttonatx:(int) x andy:(int) y withchallenge:(id)challengeid {     cgrect buttonrect = cgrectmake(x, y, 80, 78);      challengebutton *capebutton = [challengebutton buttonwithtype:uibuttontypecustom];      [capebutton setbackgroundcolor:[uicolor clearcolor]];     [capebutton setframe:buttonrect];      [capebutton addtarget:self action:@selector(highlightimage:) forcontrolevents:uicontroleventtouchupinside];      uiimage *capeimage = [uiimage imagenamed:@"capepower.png"];     [capebutton setbackgroundimage:capeimage forstate:uicontrolstatenormal];      [scrollview addsubview: capebutton]; }

highlightimage called each buttons selector, determine button pressed. (and ideally element availablearray button associated with)... i've subclasses uibutton , added int value able call [sender setchallengeid:]

- (void) highlightimage:(id)sender {      if([sender isselected] == no){         [sender setselected:yes];          [sender setchallengeid:selectedchallenge];         nslog(@"sender = %d",[sender challengeid]);              uiimage *selectedimage = [uiimage imagenamed:@"powerbarhand.png"];         [sender setbackgroundimage:selectedimage forstate:uicontrolstateselected];      }     else {         [sender setbackgroundimage:[uiimage imagenamed:@"handstandpower.png"] forstate:uicontrolstatenormal];            [sender setselected:no];         selectedchallenge = 0;     } }

my problem cannot figure out how appdelegate's availablearray element highlightimage, uibutton's [capebutton addtarget:challengeid action:@selector(highlightimage:) forcontrolevents:uicontroleventtouchupinside] not allow me pass challengeid loop earlier in flow.

i able pass integer value setchallengeid, , handling expected. need appdelegate.availablearray id value loop.

any direction great!:)

you availablearray highlightimage: same way got createscrollbuttons:

superherogameappdelegate *appdelegate = (superherogameappdelegate *)[[uiapplication sharedapplication] delegate];

and access appdelegate.availablearray.

i think that's not question meant ask, though. think want call setchallengeid: on each challengebutton create in createbuttonatx:andy:withchallenge:. in highlightimage: selectedchallenge = [sender challengeid] rather [sender setchallengeid:selectedchallenge].

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...

c# - How to set Z index when using WPF DrawingContext? -

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.
