透明的UINavigationBar [英] Transparent UINavigationBar

问题描述

我是ios的新手，我找到了使UINavigationBar透明的解决方案. 可以在我的项目文件中的哪个位置放置此代码

Am newbie to ios and I found this solution on making the UINavigationBar Transparent. Where in my project files can I put this code

[self.navigationBar setBackgroundImage:[UIImage new]
                     forBarMetrics:UIBarMetricsDefault];
self.navigationBar.shadowImage = [UIImage new];
self.navigationBar.translucent = YES;

以便将其应用于正在使用导航控制器的整个项目中.

So that it is applied in my entire project where navigation controller is being used.

推荐答案

在您的rootViewController的viewDidLoad函数中输入以下代码:

Put in your viewDidLoad function of your rootViewController this code:

[self.navigationController.navigationBar setBackgroundImage:[UIImage new]
                     forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.navigationBar.translucent = YES;
self.navigationController.view.backgroundColor = [UIColor clearColor];

Swift 2.x:

if let navigationBar = navigationController?.navigationBar {
        navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .Default)
        navigationBar.shadowImage = UIImage()
        navigationBar.translucent = true
        navigationController?.view.backgroundColor = .clearColor()
    }

迅速3:

if let navigationBar = navigationController?.navigationBar {
        navigationBar.setBackgroundImage(UIImage(), for: .default)
        navigationBar.shadowImage = UIImage()
        navigationBar.isTranslucent = true
        navigationController?.view?.backgroundColor = .clear
    }

这可以肯定！ 透明UINavigationBar .
