UIAlertController泄漏 [英] Leaks with UIAlertController

问题描述

我在我的应用中添加了 UIAlertController ，方法是使用以下方法在 UIViewController 上创建一个类别：

I added UIAlertController in my app by creating a category on UIViewController with the following method:

- (void)showAlertViewWithTitle:(NSString *)title
                       message:(NSString *)message
                       actions:(NSArray *)alertActions
{
   UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title ? : @"" message:message preferredStyle:UIAlertControllerStyleAlert];

   if (alertActions.count) {
      for (UIAlertAction *action in alertActions) {
         [alertController addAction:action];
      }
   } else {
      UIAlertAction *action = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil];
      [alertController addAction:action];
   }

   [self presentViewController:alertController animated:YES completion:nil];
}

首先，一切看起来都不错但是当我用仪器分析泄漏时，每次我称之为这种方法，会出现一些泄漏：

At first, everything looks great but when I analyze leaks with Instruments, each time I call this method, some leaks appear:

以下是 showAlertViewWithTitle：message：actions：的调用是如何完成的

Here is how the call of showAlertViewWithTitle:message:actions: is done

[self showAlertViewWithTitle:nil message:@"Test message" actions:nil];

我知道为什么会收到所有这些泄漏？

Any idea why I get all these leaks?

- 编辑 -

我在示例项目中尝试了以下内容：

I tried the following in a sample project:

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"title" message:@"message"
                                                   delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertView show];

我得到同样的泄密。我真的不确定发生了什么...

and I get the same leaks. I'm really not sure what's going on...

推荐答案

这是一个iOS错误。

这也是SO问题的重复 UTAlertController或UIActionSheet的iOS 8仅内存泄漏提前1天发布。

This is also a duplicate of SO question iOS 8 Only Memory Leak with UIAlertController or UIActionSheet posted 1 day earlier.

参见 Apple Bug Reporter 问题 21005708 ，ARC下的UIAlertController内存泄漏。

See Apple Bug Reporter issue 21005708, Memory leak in UIAlertController under ARC.
