iphone - Getting EXC_BAD_ACCESS when loading view (MBProgressHUD+ASIHTTPRequest) -

-

greetz,

i having issues managing "loading" screen on mainviewcontroller (the first view user accesses.) first view downloads image , puts on uiimageview. while happens mbprogresshud displayed. then, user goes secondview own controller. user uploads image , goes back. when user goes mainview, mainview gets reloaded same image before not displayed. logically, "loading" mbprogresshud should display aswell. nonetheless crashes before can let display, crashes while making transition.

the thing error exc_bad_access comes if have mbprogresshud implemented (must problem memory management don't seem it...) these segments code in question:

mainviewcontroller.m

- (void)viewdidload {       hud = [[mbprogresshud alloc] initwithview:self.view];    [self.view addsubview:hud];    hud.delegate = self;    hud.labeltext = @"please wait";    [hud showwhileexecuting:@selector(loadingofimageandinformation) ontarget:self        withobject:nil animated:yes];    [super viewdidload]; }  - (void) loadingofimageandinformation {     // [...] url , blabla.     asihttprequest *request = [asihttprequest requestwithurl:imageurl];     [request setdelegate:self];     [request setdidfinishselector:@selector(requestloaddone:)];     [request setdidfailselector:@selector(requestloadwentwrong:)];     [request setdownloadprogressdelegate:hud];     [request startasynchronous]; }  - (void)hudwashidden {    // remove hud screen when hud hidded    [hud removefromsuperview];    [hud release];    // hud = nil; tried because found on     // answer in s.o. didn't quite work.     // don't think same case.    // tried putting on dealloc method ,     // didreceivememorywarning no avail...  }

this other question treats similar problem didn't solve mine.

thank future help!!

you set hud downloadprogressdelegate of request. perhaps request tries send message after release hud. if run code in debugger, stack trace on crash should tell if case.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
