ios - 导航栏背景色-半透明为无

Question

我想将导航栏的背景颜色更改为纯绿色。

规则:我不能乱用 AppDelegate :)

我试过:

//It's green but it's translucent 
[self.navigationController.navigationBar setBackgroundColor:[UIColor colorWithRed:77/255.0 green:255/255.0 blue:100/255.0 alpha:1.0f]];

//It's white, first line has no effect
[self.navigationController.navigationBar setBackgroundColor:[UIColor colorWithRed:77/255.0 green:255/255.0 blue:100/255.0 alpha:1.0f]];
[self.navigationController.navigationBar setTranslucent:NO];

//Same result as case 1
[self.navigationController.navigationBar setAlpha:0.0f];
[self.navigationController.navigationBar setBackgroundColor:[UIColor colorWithRed:77/255.0 green:255/255.0 blue:100/255.0 alpha:1.0f]];

//Too dark
[self.navigationController.navigationBar setBarStyle:UIBarStyleBlackTranslucent];
[self.navigationController.navigationBar setBackgroundColor:[UIColor colorWithRed:77/255.0 green:255/255.0 blue:100/255.0 alpha:1.0f]];

//Only affects the back button's color:
[self.navigationController.navigationBar setTintColor:[UIColor greenColor]];

有什么想法吗？

谢谢，没看到还有 barTintColor 和 TintColor。接受最早的答案。

在您的 viewController didLoad 方法中使用这行代码

self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:29.0f/255.0f green:149.0f/255.0f blue:174.0f/255.0f alpha:1.0f]
