crash - UIActionSheet crashes after appearing again on iPad -


the uiactionsheet crashes after appears second time through..

.h file

..uiactionsheetdelegate>{   uiactionsheet *popupquery; } @property (nonatomic, retain) uiactionsheet *popupquery;

.m file

-(ibaction)showactionsheet:(id)sender {  if (popupquery.visible) {     nslog(@"popupquery isvisible");      [popupquery dismisswithclickedbuttonindex:-1 animated:yes];      return; }else{   popupquery = [[uiactionsheet alloc] initwithtitle:@"title" delegate:self cancelbuttontitle:@"cancel" destructivebuttontitle:@"readibility" otherbuttontitles:@"email url", @"print", nil]; popupquery.actionsheetstyle = uiactionsheetstyleblackopaque; //[popupquery showinview:self.view];   [popupquery showfrombarbuttonitem:actionbutton animated:yes];  [popupquery release]; }   }

when release popupquery after showing actionbutton, relinquish ownership on object. if object gets deallocated popupquery point deallocated object when popupquery.visible might give crash. since have property, can –

self.popupquery = [[[uiactionsheet alloc] initwithtitle:@"title" delegate:self cancelbuttontitle:@"cancel" destructivebuttontitle:@"readibility" otherbuttontitles:@"email url", @"print", nil] autorelease];

remove release statement @ end. object valid when popupquery.visible or self.poupquery.visible in case, have ownership , can safely access object.
