IOS 导航栏各种设置,

//中间

//self.navigationItem.title = @"标题"

UIView*redView = [[UIViewalloc]initWithFrame:CGRectMake(0,0,140,40)]

redView.backgroundColor= [UIColorredColor]

UIView*greenView = [[UIViewalloc]initWithFrame:CGRectMake(20,5,100,30)]

greenView.backgroundColor= [UIColorgreenColor]

[redViewaddSubview:greenView]

self.navigationItem.titleView= redView

//右边

UIBarButtonItem*rightItem = [[UIBarButtonItemalloc]initWithTitle:@"个人信息"style:UIBarButtonItemStylePlaintarget:selfaction:@selector(goUserInfoVc:)]

UIBarButtonItem*rightItem2 = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemCameratarget:nilaction:nil]

self.navigationItem.rightBarButtonItems=@[rightItem,rightItem2]

//左边

UIBarButtonItem*leftItem = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAddtarget:nilaction:nil]

//通过图片创建barButtonItem

//生成一张不受父视图tintColor影响的图片

UIImage*image = [[UIImageimageNamed:@"github_grayscale"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]

UIBarButtonItem*leftItem2 = [[UIBarButtonItemalloc]initWithImage:imagestyle:UIBarButtonItemStylePlaintarget:nilaction:nil]

self.navigationItem.leftBarButtonItems=@[leftItem,leftItem2]

//设置导航栏

//self.navigationController.navigationBar.backgroundColor = [UIColor greenColor]

//设置导航栏的背景色

//self.navigationController.navigationBar.barTintColor = [UIColor greenColor]

//设置导航栏的样式

/*

UIBarStyleDefault浅

UIBarStyleBlack深

UIBarStyleBlackTranslucent

*/

self.navigationController.navigationBar.barStyle=UIBarStyleDefault

//设置背景图片不透明

//self.navigationController.navigationBar.translucent = NO

//修改导航左右内容的颜色

self.navigationController.navigationBar.tintColor= [UIColorgrayColor]

//隐藏自带的背景图片

[self.navigationController.navigationBarsetBackgroundImage:[[UIImagealloc]init]forBarMetrics:UIBarMetricsDefault]

//隐藏阴影图片

[self.navigationController.navigationBarsetShadowImage:[[UIImagealloc]init]]

//设置导航的toolBar

//把toolBar显示出来

self.navigationController.toolbarHidden=NO

UIBarButtonItem*toolBarItem = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemPlaytarget:nilaction:nil]

UIBarButtonItem*toolBarItem2 = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemStoptarget:nilaction:nil]

UIBarButtonItem*toolBarItem3 = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemEdittarget:nilaction:nil]

//创建木棍特效UIBarButtonItem样式Fixed

UIBarButtonItem*toolBarItem4 = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpacetarget:nilaction:nil]

toolBarItem4.width=50

UIBarButtonItem*toolBarItem5 = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpacetarget:nilaction:nil]

toolBarItem5.width=100

//创建d簧特效UIBarButtonItem样式Flexible

UIBarButtonItem*toolBarItem6 = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpacetarget:nilaction:nil]

//50棍- Play - 100棍- Stop -d簧- Edit - 50棍

self.toolbarItems=@[toolBarItem4,toolBarItem, toolBarItem5,toolBarItem2, toolBarItem6,toolBarItem3,toolBarItem4]

附加: 

[self.navigationControllersetNavigationBarHidden:!self.navigationController.navigationBarHiddenanimated:YES]

[self.navigationControllersetToolbarHidden:!self.navigationController.toolbarHiddenanimated:YES]

-(void)viewWillAppear:(BOOL)animated{

[super viewWillAppear:animated]

CGRect rect = self.navigationController.navigationBar.frame

self.navigationController.navigationBar.frame = CGRectMake(rect.origin.x,rect.origin.y,rect.size.width,84)

}

-(void)viewWillDisappear:(BOOL)animated{

[super viewWillDisappear:animated]

CGRect rect = self.navigationController.navigationBar.frame

self.navigationController.navigationBar.frame = CGRectMake(rect.origin.x,rect.origin.y,rect.size.width,44)

ios6可以用上面的的方法,ios7需要自定义view设置好高度,添加到navigationController.navigationBar上

你可以这么写：

UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0,0,320,70)]

view.backgroundColor = [UIColor redColor]

[self.navigationController.navigationBar addSubview:view]

就可以了

提供一个思路给你

AppDelegate中, 有个rootViewController

你应该把这个菜单加在rootViewController.view上面

这样的话, 无论你d出什么东西, 它都是显示在最上层的
