去除tabbar顶部的线条(包含iOS 13之后的处理)

if (@available(iOS 13, *)) {

        UITabBarAppearance *appearance = [self.tabBar.standardAppearance copy];

        appearance.backgroundImage = [UIColor GC_imageWithColor:GCColorWhite255];

        appearance.shadowImage = [UIColor GC_imageWithColor:GCColorWhite255];

        // 重置背景和阴影为透明  如果设置了阴影效果则此代码需要去掉

        //        [appearance configureWithTransparentBackground];

        self.tabBar.standardAppearance = appearance;

    } else {

        self.tabBar.backgroundImage = [UIImage new];

        self.tabBar.shadowImage = [UIImage new];

    }

备注: GCColorWhite255为 UIColorRGB(255, 255, 255)

 

//生成图片

+ (UIImage *)GC_imageWithColor:(GCColor)type

{

    NSString *key = [NSString stringWithFormat:@"%ld", (long)type];

    

    static NSMutableDictionary *dict = nil;

    if (dict == nil) {

        dict = [[NSMutableDictionary alloc] init];

    }

    

    UIImage *image = [dict objectForKey:key];

    

    if (image == nil) {

        image = [UIImage cfa_imageWithColor:[self GC_colorForType:type] size:CGSizeMake(1,1)];

        [dict setObject:image forKey:key];

    }

    return image;
