1. 导航栏的设置

首先还是在AppDelegate.m中创建对象：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #bb2ca2}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s4 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s6 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    self.window=[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
    UINavigationController* nav=[[UINavigationController alloc]initWithRootViewController:[[VCRoot alloc]init]];
    
    self.window.rootViewController=nav;
    
    [self.window makeKeyAndVisible];
    
    
    return YES;
}

然后在VCRoot中更改导航栏属性：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}span.s1 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures}span.s4 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s5 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s6 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s7 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s8 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s9 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s10 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #d12f1b}

    self.view.backgroundColor=[UIColor yellowColor];
    
    //设置导航栏风格颜色
    //UIBarStyleBlack:黑色风格，半透明风格
    self.navigationController.navigationBar.barStyle=UIBarStyleBlackOpaque;
    //设置风格为不透明
    self.navigationController.navigationBar.translucent=YES;
    //设置颜色(设置后透明度设置就不起作用了)
    self.navigationController.navigationBar.barTintColor=[UIColor redColor];
    //设置导航原色项目按钮的风格颜色
    self.navigationController.navigationBar.tintColor=[UIColor greenColor];
    self.title=@"根视图";
    
    //隐藏导航栏
    //self.navigationController.navigationBar.hidden=YES;
    
    UIBarButtonItem* btn=[[UIBarButtonItem alloc]initWithTitle:@"next" style:UIBarButtonItemStylePlain target:nil action:nil];
    
    self.navigationItem.rightBarButtonItem=btn;

2. 工具栏的设置

还是在VCRoot.m:

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}span.s1 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s2 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures}span.s4 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s7 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s8 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s9 {font-variant-ligatures: no-common-ligatures; color: #272ad8}span.s10 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}

 //实现工具栏对象
    //默认工具栏对象是隐藏的
    self.navigationController.toolbarHidden=NO;
    
    
    //用三种方法创建三个工具栏按钮
    UIBarButtonItem* btn01=[[UIBarButtonItem alloc]initWithTitle:@"left" style:UIBarButtonItemStylePlain target:nil action:nil];
    
    UIBarButtonItem* btn02=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:nil action:nil];
    
    UIButton* btnImage=[UIButton buttonWithType:UIButtonTypeCustom];
    [btnImage setImage:[UIImage imageNamed:@"1.jpg"] forState:UIControlStateNormal];
    btnImage.frame=CGRectMake(0, 0, 60, 60);
    
    UIBarButtonItem* btn03=[[UIBarButtonItem alloc]initWithCustomView:btnImage];
    
    //固定宽度占位按钮
    UIBarButtonItem* btnF01=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
    btnF01.width=100;
    
    //可变宽度占位按钮
    //UIBarButtonItem* btnF02=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    
    
    //按钮数组
    NSArray* arrayBtns=[NSArray arrayWithObjects:btn01,btnF01,btn02,btnF01,btn03,nil ];
    
    self.toolbarItems=arrayBtns;

注意

• 代码中用了三种不同方法创建工具栏按钮
• 调整工具栏按钮间隔有两种方法，固定宽度占位按钮和自动宽度占位按钮。
