我在UIViewController的子类中设置的UINavigationBar的自定义样式方面遇到麻烦。
我以前曾进行过这项工作,但不确定为什么它在这里不起作用。
我的视图控制器中有以下代码:
- (void) loadView {
[super loadView];
CGRect frame = self.view.bounds;
navBar = [[UINavigationBar alloc] initWithFrame:frame];
frame.size = [navBar sizeThatFits:frame.size];
[navBar setFrame:frame];
[navBar setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
// The following styling has no effect:
[navBar setBarTintColor:[UIColor blackColor]];
[navBar setTintColor:[UIColor grayColor]];
NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],NSForegroundColorAttributeName, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];
UIBarButtonItem * button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemPlay
target:self
action:@selector(nextView:)];
[[self navigationItem] setRightBarButtonItem:button];
[button release];
[navBar setItems:[NSArray arrayWithObject:self.navigationItem]];
[self.view addSubview:navBar];
}
最佳答案
您不应该通过初始化一个新的并将其添加为子视图来弄乱UINavigationBar。而是使用UINavigationBar.appearance
的可能性:
UINavigationBar.appearance.barTintColor = UIColor.blackColor;
UINavigationBar.appearance.tintColor = UIColor.grayColor;
请注意,这会更改应用程序各处的UINavigationBar的外观,因此会更改为
appearance
。如果这不是您想要的,可以尝试:self.navigationController.navigationBar.barTintColor = UIColor.blackColor;
self.navigationController.navigationBar.tintColor = UIColor.grayColor;
