NavigationBar.md

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];

设置导航栏为全透明，但保留导航按钮的显示：

@property (strong, nonatomic) UIImage *navBGImage;
@property (strong, nonatomic) UIImage *navShadowImage;
@property (assign, nonatomic) BOOL navTranslucent;
- (void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];
    [self.navigationController.navigationBar setBackgroundImage:self.navBGImage forBarMetrics:UIBarMetricsDefault];
    self.navigationController.navigationBar.shadowImage = self.navShadowImage;
    self.navigationController.navigationBar.translucent = self.navTranslucent;
}

- (void)setupUI{
    self.navTranslucent = self.navigationController.navigationBar.translucent;
    self.navBGImage = [self.navigationController.navigationBar backgroundImageForBarMetrics:UIBarMetricsDefault];
    self.navShadowImage = self.navigationController.navigationBar.shadowImage;

    [self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
    self.navigationController.navigationBar.shadowImage = [UIImage new];
    self.navigationController.navigationBar.translucent = YES;
}

NSDictionary *textAttributesBalck = [NSDictionary dictionaryWithObjectsAndKeys:

                                     nil];
