我试图在iOS 7中setSelected
ImageTintColor,但它不工作.这是我在AppDelegate.m中的didFinishLaunchingWithOptions下的代码
UITabBarController *tabBarController = (UITabBarController *) self.window.rootViewController;
UITabBar *tabBar = tabBarController.tabBar;
for (UITabBarItem *item in tabBar.items)
{
UIImage *image = item.image;
UIImage *correctimage = [image imageWithRenderingMode:UIImageRenderingModeAlwaystemplate];
item.image = correctimage;
}
[[UITabBar appearance] setTintColor:[UIColor whiteColor]];
[[UITabBar appearance] setSelectedImageTintColor:[UIColor colorWithRed:44.0/255.0 green:176.0/255.0 blue:28.0/255.0 alpha:1.0]];
[[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:51.0/255.0 green:51.0/255.0 blue:51.0/255.0 alpha:1.0]];
它仍然不会显示selectedImageTintColor.选择时为白色;灰色未选择.我究竟做错了什么？
解决方法
这是iOS 7中的已知问题.tintColor用于所选标签图像. selectedImageTintColor完全被忽略.没有办法调整未选择的选项卡图像.
看到这个discussion on the Apple Developer Forums.
