我有一个测试,为我的tabbar
添加阴影,但它没有用。我的代码如下:
_button.layer.shadowColor = [UIColor grayColor].CGColor;
_button.layer.shadowOffset = CGSizeMake(4,4);
_button.layer.shadowOpacity = 0.8;
_button.layer.shadowRadius = 4;
/* remove tab-line */
[[UITabBar appearance] setShadowImage:[[UIImage alloc] init]];
[self.tabBarController.tabBar setClipsToBounds:YES];
self.tabBarController.tabBar.layer.shadowColor = [UIColor grayColor].CGColor;
self.tabBarController.tabBar.layer.shadowOffset = CGSizeMake(0,-4);
self.tabBarController.tabBar.layer.shadowOpacity = 0.8;
self.tabBarController.tabBar.layer.shadowRadius = 4;
我还拍了一张照片来表明:
答案 0 :(得分:2)
使用阴影创建图像,然后使用如下。
[[UITabBar appearance] setBackgroundImage:[[UIImage alloc] INITWITHYOURCUSTOMIMAGE]];
[[UITabBar appearance] setShadowImage:[[UIImage alloc] INITWITHYOURCUSTOMIMAGE]];
在swift:
UITabBar.appearance().shadowImage = UIImage(named:"YOURIMAGE")
UITabBar.appearance().backgroundImage = UIImage(named:"YOURIMAGE")
