Xcode在界面构建器中意外退出 [英] Xcode quit unexpectedly in interface builder

问题描述

我在Xcode（Cocoa App OSX，Objective-C）中开始了一个新项目。每次我试图添加一个按钮到一个窗口在Interface Builder（拖放）我收到以下错误和Xcode退出。
UNCAUGHT EXCEPTION（NSUnknownKeyException）：[valueForUndefinedKey：]：此类不是键值编码符合springLoaded的键。

Xcode版本6.3 Yosemite 10.10.3

任何人遇到此类行为？

部分崩溃：

 崩溃的线程：0调度队列：com.apple.main-thread 
 
异常类型：EXC_CRASH（SIGABRT） 
异常代码：0x0000000000000000,0x0000000000000000 
 
特定于应用程序的信息：
 ProductBuildVersion：6D570 
 UNCAUGHT EXCEPTION（NSUnknownKeyException）：[< NSButton 0x7fb46e18f090& valueForUndefinedKey：]：这个类不是键值编码兼容的键springLoaded。 
 UserInfo：{

 NSUnknownUserInfoKey = springLoaded; 
}

 5 0x00007fff8db4cccb  -  [NSObject（NSKeyValueCoding ）valueForKey：]（在Foundation中）
  

更新：
但是当我尝试保存我得到这个警报：
不幸的是这发生在Xcode 6.3.1

解决方案

最后我得到了苹果解决方案的答案。 / p>

这样做的原因是我使用OSX种子构建OS X 10.10.3（14D87h）。

这是与Force Touch触控板相关的新API。它是在OS X
10.10.3中添加的，但只在种子版本中添加

I started a new project in Xcode (Cocoa App OSX, Objective-C). Every time I try to add a button to a window in Interface Builder(drag and drop) I receive the following error and Xcode quits. "UNCAUGHT EXCEPTION (NSUnknownKeyException): [ valueForUndefinedKey:]: this class is not key value coding-compliant for the key springLoaded."

Xcode Version 6.3 (6D570) on Yosemite 10.10.3

Anyone experienced such behavior?

part of the crash:

Crashed Thread:        0  Dispatch queue: com.apple.main-thread

Exception Type:        EXC_CRASH (SIGABRT)
Exception Codes:       0x0000000000000000, 0x0000000000000000

Application Specific Information:
ProductBuildVersion: 6D570
UNCAUGHT EXCEPTION (NSUnknownKeyException): [<NSButton 0x7fb46e18f090> valueForUndefinedKey:]: this class is not key value coding-compliant for the key springLoaded.
UserInfo: {
    NSTargetObjectUserInfoKey = "<NSButton: 0x7fb46e18f090>";
    NSUnknownUserInfoKey = springLoaded;
}
Hints: None
Backtrace:

  1  0x00000001050ee184 DVTFailureHintExceptionPreprocessor (in DVTFoundation)

  5  0x00007fff8db4cccb -[NSObject(NSKeyValueCoding) valueForKey:] (in Foundation)

Update: Xcode now somehow survived the button add but when I try to save I get this Alert: Unfortunately this happens with Xcode 6.3.1

解决方案

Finally I got an answer from apple devforums.

The reason for this is that I use OSX seed build OS X 10.10.3 (14D87h).

This is new API related to Force Touch trackpads. It was added in OS X 10.10.3, but only in seed builds
