UINavigationBar导航栏相关设置

设置导航颜色

[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:1]];

[[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x067AB5)];

设置导航文字颜色

[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

设置导航背景

[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"nav_bg.png"] forBarMetrics:UIBarMetricsDefault];

设置多个导航按钮

UIBarButtonItem *shareItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:nil];

UIBarButtonItem *cameraItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:nil];

NSArray *actionButtonItems = @[shareItem, cameraItem];

self.navigationItem.rightBarButtonItems = actionButtonItems;

设置导航字体

NSShadow *shadow = [[NSShadow alloc] init];

shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];

shadow.shadowOffset = CGSizeMake(0, 1);

[[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys: [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName, shadow, NSShadowAttributeName, [UIFont fontWithName:@"HelveticaNeue-CondensedBlack" size:21.0], NSFontAttributeName, nil]];

说法二：

方法1

在导航向上添加一个titleView，可以使用一个label，再设置label的背景颜色透明，字体什么的设置就很简单了。

//自定义标题视图

UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];

titleLabel.backgroundColor = [UIColor grayColor];

titleLabel.font = [UIFont boldSystemFontOfSize:20];

titleLabel.textColor = [UIColor greenColor];

titleLabel.textAlignment = NSTextAlignmentCenter;

titleLabel.text = @"新闻";

self.navigationItem.titleView = titleLabel;

方法2

// 设置 标题的颜色和字号

[self.navigationBar setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:2

0],NSForegroundColorAttributeName:[UIColor whiteColor]}];

self.navigationBar.barTintColor =[UIColor whiteColor]];

设置tabbar的背景颜色

self.tabBar.barTintColor = [UIColor whiteColor];
