Xcode 在颜色面板中选择选项卡时崩溃
Xcode crashes on selecting tab in color panel
我几个小时前就遇到了这个奇怪的问题，而且它突然开始了。每当我尝试在 Xcode 的颜色面板中 select 不同的选项卡时，整个 Xcode 都会因错误而崩溃，
UNCAUGHT EXCEPTION (NSRangeException): Cannot remove an observer <NSColorPickerPageableNameListScrollView 0x7fb8f6ce0910> for the key path "contentLayoutRect" from <HighlightColorPanel 0x7fb8f6c94af0> because it is not registered as an observer.

非常感谢您。
这似乎是 Apple 方面的问题。让我为您消化该日志：
UNCAUGHT EXCEPTION: Cannot remove an observer <NSColorPickerPageableNameListScrollView 0x7fb8f6ce0910> for the key path "contentLayoutRect" from <HighlightColorPanel 0x7fb8f6c94af0> because it is not registered as an observer.
因此，在 Xcode 的代码中，它试图做的是删除类型为 NSColorPickerPagableNameListScrollView 的观察者（在 up/down 列表中选择开发人员的颜色偏好IB) 在内存地址 0x7b7f6ce0910 来自 HighlightColorPanel （可能是颜色选择器的对话框）在内存地址 0x7fb8f6c94af0 在滚动视图注册为颜色观察者之前关键路径的选择器 contentLayoutRect.
通俗地说，滚动颜色视图是颜色选择器的观察者，可以更轻松地查看您的颜色偏好。当颜色选择器选择一种颜色时，它会向它的观察者发送一个通知，即滚动的颜色框。
但是，当框关闭时，滚动视图应该从 观察者树 中删除自己，即 观察者[的项目列表] =37=] 的盒子，努力摆脱（并释放资源）盒子。
该错误仅存在于该部分代码中，因为显然，滚动视图 从未注册为关键路径 contentLayoutRect 的观察者 。它是 观察者 其他所有 但 的观察者。由于它在试图摆脱它时无法分辨观察者是什么，因此系统崩溃并崩溃。
就我而言，完全相同的问题是由我通过 Alcatraz 安装的 ColorSenseRainbow 插件引起的。我一删除它，一切就恢复正常了。
我几个小时前就遇到了这个奇怪的问题，而且它突然开始了。每当我尝试在 Xcode 的颜色面板中 select 不同的选项卡时，整个 Xcode 都会因错误而崩溃，

非常感谢您。
这似乎是 Apple 方面的问题。让我为您消化该日志：
UNCAUGHT EXCEPTION: Cannot remove an observer <NSColorPickerPageableNameListScrollView 0x7fb8f6ce0910> for the key path "contentLayoutRect" from <HighlightColorPanel 0x7fb8f6c94af0> because it is not registered as an observer.
因此，在 Xcode 的代码中，它试图做的是删除类型为 NSColorPickerPagableNameListScrollView 的观察者（在 up/down 列表中选择开发人员的颜色偏好IB) 在内存地址 0x7b7f6ce0910 来自 HighlightColorPanel （可能是颜色选择器的对话框）在内存地址 0x7fb8f6c94af0 在滚动视图注册为颜色观察者之前关键路径的选择器 contentLayoutRect.
通俗地说，滚动颜色视图是颜色选择器的观察者，可以更轻松地查看您的颜色偏好。当颜色选择器选择一种颜色时，它会向它的观察者发送一个通知，即滚动的颜色框。
但是，当框关闭时，滚动视图应该从 观察者树 中删除自己，即 观察者[的项目列表] =37=] 的盒子，努力摆脱（并释放资源）盒子。
该错误仅存在于该部分代码中，因为显然，滚动视图 从未注册为关键路径 contentLayoutRect 的观察者 。它是 观察者 其他所有 但 的观察者。由于它在试图摆脱它时无法分辨观察者是什么，因此系统崩溃并崩溃。
就我而言，完全相同的问题是由我通过 Alcatraz 安装的 ColorSenseRainbow 插件引起的。我一删除它，一切就恢复正常了。
