UIActionSheet showInview方法导致第二次崩溃应用程序 [英] UIActionSheet showInview method cause crashed the app in second time

问题描述

我正在使用UIActionSheet来选择选项。相同的代码在iOS 7中运行良好，但问题出现在iOS 8中。

I am using UIActionSheet to choose options. The same code work fine in iOS 7 but the problem arise in iOS 8.

actionSheet = [[UIActionSheet alloc] initWithTitle:@"Choose an option" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:Nil otherButtonTitles:@"Option1", @"Option2", @"Option2", nil];

在IBAction上，我使用以下代码显示操作表。

On a IBAction I am using the below code to show action sheet.

[actionSheet showInView:[self view]];

这是第一次正常工作。但是，由于EXE_BAD_ACCESS

It's work fine for the first time. But in second time the app got crashed due to EXE_BAD_ACCESS

推荐答案

从 @TonyMkenu启发的评论我在下面做了以及它的工作。

Inspiring from @TonyMkenu's comment I do below and it's work.

完成dismissViewControllerAnimated后，我发布了操作表。

On completion of dismissViewControllerAnimated I released the action sheet.

[self dismissViewControllerAnimated:YES completion:^{
        actionSheet =nil;
}];

在致电之前，我每次都分配了行动表。

And before calling I allocated the action sheet every time.

if(! actionSheet)
   actionSheet = [[UIActionSheet alloc] initWithTitle:@"Choose an option" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:Nil otherButtonTitles:@"Option1", @"Option2", @"Option2", nil];

[actionSheet showInView:[self view]];
