Question

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // Override point for customization after application launch.

  UIColor *navBarColor =
  [UIColor colorWithPatternImage:[UIImage imageNamed:@"SandPattern.jpg"]];

    if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1 {
    [[UINavigationBar appearance] setTintColor:navBarColor];
    }
        else {
    [[UINavigationBar appearance] setBarTintColor:navBarColor];
        }
        // various functions....
        return YES;
}

应用程序崩溃并抛出以下错误。

*** -[UICGColor encodeWithCoder:], /SourceCache/UIKit/UIKit-3318/UIColor.m:1448

中的断言失败

*** -[UICGColor encodeWithCoder:], /SourceCache/UIKit/UIKit-3318/UIColor.m:1448

中的断言失败

libc++abi.dylib：terminate_handler意外地抛出异常

我移动代码将导航栏更新为一个函数，并在其他人在AppDelegate.m中运行后调用它，它运行正常。仍然在寻找崩溃背后的确切逻辑。

-(void)updateUI{
    UIColor *navBarColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"SandPattern.jpg"]];
    //    [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0];
    if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1){
        [[UINavigationBar appearance] setTintColor:navBarColor ];
    }
    else {
        [[UINavigationBar appearance] setBarTintColor: navBarColor];
    }
}

这样的最终代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
            // Override point for customization after application launch.

         // various functions....
           [self updateUI];
            return YES; 
 }

断言失败 - [UICGColor encodeWithCoder：]，/ SourceCache / UIKit / UIKit-3318 / UIColor.m
