如何让导航栏像第一张图片一样透明?
How can I make the navigation bar transparent like first image?
推荐答案
您可以为半透明应用如下导航栏图像.
You can apply Navigation Bar Image like below for Translucent.
目标-C:
[self.navigationController.navigationBar setBackgroundImage:[UIImage new]
forBarMetrics:UIBarMetricsDefault]; //UIImageNamed:@"transparent.png"
self.navigationController.navigationBar.shadowImage = [UIImage new];////UIImageNamed:@"transparent.png"
self.navigationController.navigationBar.translucent = YES;
self.navigationController.view.backgroundColor = [UIColor clearColor];
斯威夫特 3:
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default) //UIImage.init(named: "transparent.png")
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.isTranslucent = true
self.navigationController?.view.backgroundColor = .clear
