尝试更改导航栏背景颜色，但失败

Question

I used the code below to change the background color of navigationbar

- (void)viewDidLoad
{

    [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithHexString:@"6cd3c5"]];

    [super viewDidLoad];

}

the bar background color does not change immediately, I have to pushViewController:someViewController

and go back, the color can change.

Your comment welcome

Answer 1

Try this:

[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithHexString:@"6cd3c5"]];
[self.navigationController.navigationBar setTranslucent:NO];

Read this for more clarification.

Answer 2

appearance is used for the future appearance. if you want to appearance then use before the view load.

else use

    [self.navigationController.navigationBar setBarTintColor:[UIColor colorWithHexString:@"6cd3c5"]];
