iOS8beta中的UIActionSheet崩溃 [英] UIActionSheet crash in iOS8beta
本文介绍了iOS8beta中的UIActionSheet崩溃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的代码只需点击按钮即可显示UIActionSheet。
但是当我在iPad中使用XCode5.1 + iOS8beta构建它时会崩溃。
I have code which simply display UIActionSheet on button click. but it will crash when I build it using XCode5.1 + iOS8beta in iPad.
下面是我用来显示UIActionSheet的代码。
below is a code I used to display UIActionSheet.
UIActionSheet *tmpActionSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:self
cancelButtonTitle:@"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:
@"Ok",
nil];
[tmpActionSheet showInView:self.view];
注意：
- 完美适用于XCode6beta + iOS8beta（iPhone / iPad）两个）
- 它完全适用于XCode5.1 + iOS8beta（仅适用于iPhone）
Note:
- It perfectly work with XCode6beta + iOS8beta (iPhone/iPad both)
- It perfectly work with XCode5.1 + iOS8beta (iPhone only)
异常的日志记录如下。

Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

问题：
1]为什么我的应用程序崩溃？
2]是iOS8beta错误吗？
Question :
1] Why my application is crash ?
2] Is it iOS8beta bug ?
补丁直到苹果修复此问题
为
创建 Objective-C分类 UIActionSheet class
Patch till apple fix this issue
Create
Objective-C categor for UIActionSheet class
代码：
#define SYSTEM_VERSION_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
#define SYSTEM_VERSION_GREATER_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)

推荐答案
我也有过一样的问题。我使用 ShowFromBarButtonItem 函数而不是ShowInView函数。
I also had the same problem. i used ShowFromBarButtonItem function instead of ShowInView Function.
[organizeActionSheet showFromBarButtonItem:btnAction animated:NO];
如果使用ShowFromRect或showFromBarButtonItem运行时异常将不会。
i认为这是IOS8 Beta的一个错误，当我使用ShowInView运行时异常即将到来。
if use ShowFromRect or showFromBarButtonItem runtime exception will not come. i think it is a bug of IOS8 Beta, when i use ShowInView Runtime exception is coming.
IOS Beta 4中没有发生此错误。 。
使用Xcode 5.1构建时，我在调试窗口中收到一些警告消息，但确实显示了操作表。在iOS 8 beta 4中，它显示为视图外侧的小弹出窗口（侧面），而在iOS 7中，它曾经显示为从视图底部向上滑动的按钮。
I do get some warning messages in the debug window when built using Xcode 5.1, but the action sheet does appear. In iOS 8 beta 4, it appears as a small pop-up window outside of the view (at the side), whereas in iOS 7, it used to appear as buttons that slid up from the bottom of the view.
