Question

在iOS 10之前，我们可以使用

隐藏阴影渐变线

self.tabBar.shadowImage = [UIImage new];

但这个解决方案在iOS 10之后无效，有什么想法吗？

Answer 1

我找到了一个忽略iOS版本的通用解决方案

<强>目标C

BOOL isFound = NO;
for (UIView *view in self.tabBar.subviews) {
    for (UIView *v in view.subviews) {
        if (v.frame.size.height < 2.0f) {
            v.hidden = YES;
            isFound = YES;
            break;
        }
    }
    if (isFound) {
        break;
    }
}

Answer 2

试试这可能会有所帮助。

<强> - ＆GT;对于目标C

1. [[UITabBar appearance] setBackgroundImage:[[UIImage alloc] init]]; 
2. [[UITabBar appearance] setShadowImage:[[UIImage alloc] init]];
3. [[UITabBar appearance] setValue:@(YES) forKeyPath:@"_hidesShadow"];
4. [[UITabBar appearance] setShadowImage: nil];

<强> - ＆GT;对于Swift

1. UITabBar.appearance().shadowImage = UIImage()
2. UITabBar.appearance().backgroundImage = UIImage()
3. UITabBar.setValue(true, forKey: "_hidesShadow")
4. UITabBar.appearance().shadowImage = nil

self.tabBar.shadowImage = [UIImage new];在iOS 10之后无法运行
