如何在带有ARC的UIViewController的addSubview之后保留视图 [英] how to retain view after addSubview of UIViewController with ARC

问题描述

当我使用ARC并添加UIViewController的视图时如何处理情况?

How to handle situation when I use ARC and add view of UIViewController?

MyViewController *vc = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil];
[someView addSubview:vc.view]; //this retain vc.view

因为addSubview保留onlu视图，而不是控制器，所以控制器被释放.在ARC之前，有一种可以根据需要保留控制器的方法，但是如何防止ARC释放View Controller?

because addSubview retain onlu view, not controller, so controller is released. Before ARC there was a way to retain controller as long as neede, but how to prevent ARC to release View Controller?

推荐答案

我有类似的情况，通过将vc声明为具有默认Strong属性的属性来解决.

I had similar situation solved by declaring vc as property with default strong attribute.
