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

【中文标题】-[UICGColor encodeWithCoder:], /SourceCache/UIKit/UIKit-3318/UIColor.m 中的断言失败

【英文标题】：Assertion failure in -[UICGColor encodeWithCoder:], /SourceCache/UIKit/UIKit-3318/UIColor.m

【问题描述】：

- (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 意外抛出异常

【参考方案1】：

我移动了代码以将导航栏更新为一个函数，并在 AppDelegate.m 中的其他函数之后调用它，它工作正常。仍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;
