ios – iPhone应用程序崩溃：UIKit

2015年10月29日更新：可能找到了原因.我正在根据 this StackOverflow post创建一个渐变层 – 它对我和我测试过的所有其他人来说都非常好,但是其他人可能会遇到问题吗？

CAGradientLayer * g  = [CAGradientLayer layer];
UIColor * colourFrom = [UIColor colorWithRed:0.1 green:0.7 blue:0.3  alpha:1.0];
UIColor * colourTo   = [UIColor colorWithRed:0.1 green:0.8 blue:0.4 alpha:1.0];

g.frame        = self.view.bounds;
g.cornerRadius = 10;
g.startPoint   = CGPointMake(0.0,0.5);
g.endPoint     = CGPointMake(1.0,0.5);
g.colors       = [NSArray arrayWithObjects:(id)[colourFrom CGColor],(id)[colourTo CGColor],nil];

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

根据我的读数,这是UIApperence或ios 6中的[UIColor colorWithPatternImage：]的错误

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
