ipad – iOS8beta中的UIActionSheet崩溃

我有一些代码,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.

下面是我用来显示UIActionSheet的代码.

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)
– 完美适用于XCode5.1 iOS8beta(仅限iPhonE)

异常的日志记录如下.

2014-06-23 15:54:04.860 ActionSheetDemo[680:191598] Unable to simultaneously satisfy consTraints.
    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)

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConsTraints to catch this in the debugger.
The methods in the UIConsTraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be Helpful.

题 ：
1]为什么我的应用程序崩溃？
2]是iOS8beta的bug吗？

补丁直到苹果解决了这个问题
