导航栏背景颜色 - 半透明是没有

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：）

我试过了：

//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]];

所有想法？

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

Answer 1

在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] 

Answer 2

使用这个，

self.navigationController.navigationBar.tintColor=[UIColor colorWithRed:19.0/255.0f green:52.0/255.0f blue:36.0/255.0f alpha:1];
