iphone - Help with UIPopOverController size -

-

so have view bunch of button in uiscrollview. when user presses button, want uipopovercontroller display pointing @ selected button. kind of works, popover wrong size , points random point in view. here code. in advance.

-(void)detail:(id)sender{     uibutton *button = sender;     nslog(@"tag = %i", button.tag);      uinavigationcontroller *navcontroller = [[uinavigationcontroller alloc] initwithrootviewcontroller:viewcontroller];     if (ui_user_interface_idiom() == uiuserinterfaceidiompad) {     self.popover = [[uipopovercontroller alloc] initwithcontentviewcontroller:navcontroller];     self.popover.delegate = self;     [self.popover presentpopoverfromrect:button.bounds inview:self.view permittedarrowdirections:uipopoverarrowdirectionany animated:yes]; }

than problem size of popover: in view inside popover, have:

self.contentsizeforviewinpopover = scroll.contentsize; nslog(@"%f, %f", scroll.contentsize.height, scroll.contentsize.width); nslog(@"showing: %f, %f",  self.contentsizeforviewinpopover.height,  self.contentsizeforviewinpopover.width);

and both logs matching. think should work correctly. doesn't. here screen shot. let me know if need more of code. in advance.

screen shot of error

regarding size of popover only: managed variable heighted uilabel:

uilabel *hinweis; hinweis.text = @"..."; hinweis.frame = cgrectmake(x,y,width,800); [hinweis sizetofit];

and arrow: have tried different inview param self.parentviewcontroller.view?

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
