我正在尝试setSelectedImageTintColor
在 iOS 7 中使用,但它不起作用。这是我下面的AppDelegate.m
代码didFinishLaunchingWithOptions
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。选中时为白色;未选中时为灰色。我究竟做错了什么?
