xCode TabBarItem标题和图标颜色

Question

当 Tabbaritem 标题和图标未突出显示时，我似乎无法更改它们的颜色。我希望标题和图标的颜色从灰色变为另一种颜色。

Answer 1

在AppDelegate.m中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UITabBar appearance] setSelectedImageTintColor:[UIColor redColor]];
return YES;
}

用于更改文本颜色viewController.m

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
 self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
{
[self.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor greenColor],UITextAttributeTextColor,nil] forState:UIControlStateNormal];
}
return self;
}
