Ios 导航栏背景色-半透明性为否

我想将导航栏的背景色更改为纯绿色

规则：我不能搞乱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，我没看到还有barTintColor和TintColor。接受最早的答案。

请使用以下代码，这可能会对您有所帮助

navController.navigationBar.barTintColor = [UIColor yourcolor];

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] 

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];

使用navigationBar的barTintColor属性

您是否使用了情节提要？然后选择viewcontroller，并在inspector中的“模拟度量”下将顶部栏设置为不透明导航栏
