iOS导航栏配置问题

1:导航栏

//更改状态栏,但是需要加字段 View controller-based status bar appearance == NO 默认是YES

//[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

//1.设置导航条的颜色

self.navigationController.navigationBar.barTintColor = [UIColor redColor];

//2.关闭导航条的毛玻璃效果.

// self.navigationController.navigationBar.translucent = YES;

//3.隐藏导航条

self.navigationController.navigationBar.hidden = NO;

//4.设置导航条内容的渲染颜色

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

//5.设置导航条的背景图片.

//图片尺寸不一样,显示的效果是不同的;(一定要非常严格)

// [self.navigationController.navigationBar setBackgroundImage:<#(UIImage *)#> forBarMetrics:<#(UIBarMetrics)#>];

//6.设置导航条标题文字的大小和颜色

NSDictionary *dic = @{NSFontAttributeName:[UIFont boldSystemFontOfSize:18], NSForegroundColorAttributeName:[UIColor redColor]};

self.navigationController.navigationBar.titleTextAttributes = dic;

2:

/**

* 针对当前一个界面单独定制导航条内容

*/

- (void)customizedNavigationBarContent {

//配置导航条上显示的标题

self.navigationItem.title = @"第一个界面";

//配置导航条的标题视图

UISegmentedControl *segment = [[UISegmentedControl alloc] initWithItems:@[@"国家", @"地区"]];

self.navigationItem.titleView = segment;

//配置左边内容,显示废纸篓按钮

UIBarButtonItem *leftItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemTrash target:self action:@selector(handleTrash:)]; self.navigationItem.leftBarButtonItem = leftItem;

//配置右边内容

UIBarButtonItem *rightItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(handleAdd:)];

self.navigationItem.rightBarButtonItem = rightItem;

}

/**

* //在对navigationBar进行设置时,比如添加一个scrollView,系统会自动将ScrollView下移偏离TOP 64个像素点,为了避免这样,我们有两种方法:

1.将navigationBar的毛玻璃效果关闭;

2.将navigationBar的属性automaticallyAdjustsScrollViewInsets = NO;
