iphone - Release UIViewController give exception -


i have uiviewcontroller add uiviewcontroler this:

reportviewcontroller *reportvc = [[reportviewcontroller alloc]initwithnibname:@"reportviewcontroller" bundle:nil]; [self.view addsubview:reportvc.view];

and try add 

[reportvc release];

after lines , exepction when try remove reportvc.view 

[self.view removefromsuperview];

did make error while release this?

in code removing "self.view" superview, shouldn't.
have remove "reportvc.view" superview.

you can write this:

[reportvc.view removefromsuperview];  [reportvc release];  reportvc = nil;
