2015年10月27日更新：仍然看到来自Crashlytics的这些崩溃.
2015年10月26日更新：我发现this thread on StackOverflow似乎与我所拥有的问题完全相同(但没有答案……),但他们使用的是Facebook / Twitter活动表,我不是.只是帮助诊断问题的东西.
刚刚向App Store发布了一个应用程序,我们看到Crashlytics中发生这种崩溃的用户比例很小(约2％)：
它似乎只出现在iOS 9中,但它正在所有设备上发生.
Fatal Exception: NSInternalInconsistencyException Only RGBA or White color spaces are supported in this situation.
就个人而言,我正在运行带有9.1的iPhone 6,但我没有遇到这个问题.我也尝试过模拟器,但没有问题,所以我不确定这个bug是如何实际出现的.来自Crashlytics的堆栈跟踪如下.
好像UIColor正在被添加到NSDictionary而没有被编码,但我不会在应用程序中的任何地方这样做.它似乎也可能与UIRemoteViewController有关,但我没有在应用程序中使用它(除非使用Facebook登录导致 – 我尝试使用Facebook登录手机和模拟器,但我再也不能出现此错误).
有没有人知道可能导致这种情况的原因？

使用代码示例更新
这在应用程序中调用：didFinishLaunchingWithOptions：
// Make the app look pretty // Turn the status bar color white [[UIApplication sharedApplication] setStatusBarHidden:NO]; [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; // Nav bar: Background colour [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0.5 green:0.5 blue:0.5 alpha:1.0]]; // Nav bar: White text [[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor colorWithRed:0.2 green:0.2 blue:0.2 alpha:1.0],NSForegroundColorAttributeName,nil]]; // Nav bar: Tint colour [UINavigationBar appearance].tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"TintNavBar"]]; // Tab Bar: Background color [[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:0.5 green:0.5 blue:0.5 alpha:1.0]]; // Tab bar: Tint colour [UITabBar appearance].tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"gradientSmall"]]; // UIControlSegment: Change the colours to just white // @url https://stackoverflow.com/a/21484829/4027036 [[UISegmentedControl appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName:[Ui getColour:UI_BODY_PRIMARY]} forState:UIControlStatenormal];
解决方法
所以在你的代码中检查一下.如果您的应用程序中有该代码,则使用纯色.
这里是我得出这个结论的几个链接：
1)IOS erro at Posting to Facebook with the native Share dialog – UICGColor encodeWithCoder
2)UIApperance and various crashes
3)UIApperance and various crashes
4)iOS 6 MFMailComposeViewController: Only support RGBA or the White color space,this method is a hack
