当 ViewController 被关闭时，本地创建的对象会被释放吗？

Question

I'm throwing up around 50 UIImageViews into a view via a loop, looks something like this (Photo is just my subclass):

Photo *photoImage = [[Photo alloc] initWithImage:photo];
[self.view addSubview:photoImage];

My current design flow uses the presentViewController and dismissViewController to move along views. When this I decide to dismiss this view, are these objects removed from memory and cleaned up? Also, are my array objects removed when the viewController is dismissed, or am I suppose to be using viewDidUnload?

I'm using ARC btw. Thanks

Answer 1

use Autorelease

Photo *photoImage = [[Photo alloc] initWithImage:photo]Autorelease];

[self.view addSubview:photoImage];
