在自界说设置导航配景致时，利用下面的方法，在iOS15+体系上不起作用：
UINavigationBar *appearance = [UINavigationBar appearance];//       [appearance confi];       [appearance setBarTintColor:[UIColor whiteColor]];       [appearance setTintColor: [UIColor whiteColor]];       appearance.translucent = NO;       NSMutableDictionary *textAttribute = [NSMutableDictionary dictionary];       textAttribute[NSForegroundColorAttributeName] = MPColorBlue;//标题颜色       textAttribute[NSFontAttributeName] = [UIFont boldSystemFontOfSize:18];//标题巨细       [appearance setTitleTextAttributes:textAttribute];             UIColor *color = MPMainColor;       UIImage *backGroundImage = [UIImage imageWithColor:color];       backGroundImage = [backGroundImage resizableImageWithCapInsets:UIEdgeInsetsZero resizingMode:UIImageResizingModeStretch];       [appearance setBackgroundImage:backGroundImage forBarMetrics:UIBarMetricsDefault];//       appearance.backgroundColor = color;          //去除底部黑线       [appearance setShadowImage:[UIImage new]];但是，如你的页面有scrollView，比方table、webView这些，滑动的时候，导航颜色会变为你设置的颜色，但是一旦滑动到顶部，导航又会不正常，变成玄色；
查了资料，说在iOS15+利用下面的方法：
UINavigationBarAppearance *appearance = [[UINavigationBarAppearance alloc] init];       [appearance configureWithOpaqueBackground]; NSMutableDictionary *textAttribute = [NSMutableDictionary dictionary]; textAttribute[NSForegroundColorAttributeName] = MPColorBlue;//标题颜色 textAttribute[NSFontAttributeName] = [UIFont boldSystemFontOfSize:18];//标题巨细 [appearance setTitleTextAttributes:textAttribute];       //去除底部黑线 [appearance setShadowImage:[UIImage new]];       UIColor *color = MPMainColor;    appearance.backgroundColor = color;       self.navigationBar.standardAppearance = appearance;该方法体现和上面划一；
终极在一个文章里看到这个属性：
self.navigationBar.scrollEdgeAppearance须要把这个也设置了才会体现正常，终极完备的设置如下：
UINavigationBarAppearance *appearance = [[UINavigationBarAppearance alloc] init];       [appearance configureWithOpaqueBackground]; NSMutableDictionary *textAttribute = [NSMutableDictionary dictionary]; textAttribute[NSForegroundColorAttributeName] = MPColorBlue;//标题颜色 textAttribute[NSFontAttributeName] = [UIFont boldSystemFontOfSize:18];//标题巨细 [appearance setTitleTextAttributes:textAttribute];       //去除底部黑线 [appearance setShadowImage:[UIImage new]];       UIColor *color = MPMainColor; appearance.backgroundColor = color;       self.navigationBar.standardAppearance = appearance; self.navigationBar.scrollEdgeAppearance = appearance;我这里设置的 backgroundColor，你也可以设置BackgroundImage
