隐藏导航栏:

[self.navigationController setNavigationBarHidden:YES];

顶部导航左边按钮:

    UIButton *leftNaviBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    leftNaviBtn.frame = CGRectMake(0, 0, 44, 44);// 设置不了位置属性，可以设置大小属性
    [leftNaviBtn setBackgroundImage:[UIImage imageNamed:@"btn_more"] forState:UIControlStateNormal];
    [leftNaviBtn addTarget:self action:@selector(clickOnLeftNavigationItem:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *leftItem = [[UIBarButtonItem alloc] initWithCustomView:leftNaviBtn];
    self.navigationItem.leftBarButtonItem = leftItem;

设置顶部导航的背景颜色:

self.navigationController.navigationBar.barTintColor = COLOR_WITH_RGBA(512, 124, 200, 1);
[self.navigationController.navigationBar setTranslucent:NO];

设置顶部导航 title 颜色为白色:

[self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]}];

设置导航栏上，按钮（如返回按钮）的颜色：

self.navigationController.navigationBar.tintColor = [UIColor whiteColor];

Hide 'Back' button on navigation bar:

self.navigationItem.hidesBackButton = YES;

Two UIBarButtonItems as rightBarButtonItem

cameraButton = [[UIBarButtonItem alloc] initWithTitle:@"Camera" style:UIBarButtonItemStylePlain target:self action:@selector(cameraButton)];
writingButton = [[UIBarButtonItem alloc] initWithTitle:@"Text" style:UIBarButtonItemStylePlain target:self action:@selector(writingButton)];
NSDictionary *textAttributesBalck = [NSDictionary dictionaryWithObjectsAndKeys:
                                     [UIColor blackColor], NSForegroundColorAttributeName,
                                     nil];
self.navigationItem.rightBarButtonItems = @[writingButton, cameraButton];

Programmatically get height of navigation bar：

NSLog(@"Navframe Height=%f", self.navigationController.navigationBar.frame.size.height);
