Question

Hi I using blocks to implement the pushing of viewcontrollers onto a stack. My code is as follows:

My Question is, for memory management, where can I release the firstView instance? I tried to release it in the completion block itself but I will get a “memory issue” if I press the back button from splashView to the firstView

FirstViewController *firstView = [[FirstViewController alloc]init];

[firstView setCompletionHandler:^(BOOL isRequestInvite){

    splashView=[[AuthSplashController alloc] init];
    [splashView setCompletionHandler:onceCompleted];

    [navCon pushViewController:splashView animated:YES];
    //[firstView release];

}];

[navCon pushViewController:firstView animated:NO];

So in this case, where would be the best place to release firstView?

Answer 1

I think you can release firstView after pushing it on navigation stack, because retain count will be increased:

 [navCon pushViewController:firstView animated:NO];
 [firstView release];

Or you can mark that object as autoreleased:

 FirstViewController *firstView = [[[FirstViewController alloc]init] autorelease];
