xocde13上打包app的适配方案记录

1.navigationbar变透明

解决方法:


@implementation** UINavigationController (Extension)
/// 更改为颜色
- (void)changeBackgroundColor:(UIColor *)color {
    static UIImage *backgroundImage = nil;
    static UIImage *shadowImage = nil;
    if (!backgroundImage) {
        backgroundImage = [LGImage imageWithColor:color];
        shadowImage = [LGImage imageWithColor:[UIColor clearColor]];
    }
    
    if (@available(iOS 13.0, *)) { 
        // iOS13 之后用这个
        UINavigationBarAppearance *apparance = [[UINavigationBarAppearance alloc] init];
        [apparance configureWithOpaqueBackground];
        apparance.backgroundColor = color;
        [apparance setShadowImage:shadowImage];
        self.navigationBar.standardAppearance = apparance;
        self.navigationBar.scrollEdgeAppearance = self.navigationBar.standardAppearance;

    } else {
    // iOS15之后失效
        [self.navigationBar setBackgroundImage:backgroundImage forBarMetrics:UIBarMetricsDefault];
        [self.navigationBar setShadowImage:shadowImage];
    }
}

/// 更改为图片
- (void)changeBackgroundImage:(UIImage *)image {
  
    static UIImage *shadowImage = nil;
    if (!shadowImage) {
        shadowImage = [LGImage imageWithColor:[UIColor clearColor]];
    }
    
    if (@available(iOS 13.0, *)) {
        UINavigationBarAppearance *apparance = [[UINavigationBarAppearance alloc] init];
        [apparance configureWithOpaqueBackground];
        apparance.backgroundColor = [UIColor clearColor];
        [apparance setShadowImage:shadowImage];
        self.navigationBar.standardAppearance = apparance;
        [self.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
        self.navigationBar.scrollEdgeAppearance = self.navigationBar.standardAppearance;

    } else {
        [self.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
        [self.navigationBar setShadowImage:shadowImage];
    }
}

@end

2.tabbar变透明


- (void)changeBackgroundColor:(UIColor *)color{
    if (@available(iOS 15.0, *)) { //iOS15后添加更改tabbar新类,用这个更改背景色
        UITabBarAppearance *appearance = [[UITabBarAppearance alloc] init];
        [appearance configureWithOpaqueBackground];
        appearance.backgroundColor = color;
        self.tabBar.standardAppearance = appearance;
        self.tabBar.scrollEdgeAppearance = appearance;
    }
}
