在appdelegate里面设置
swift:
UINavigationBar.appearance().barTintColor = UIColor.init(red: 47, green: 48, blue: 52)
UINavigationBar.appearance().tintColor = UIColor.whiteColor()
UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName: UIFont.boldSystemFontOfSize(18),NSForegroundColorAttributeName: UIColor.whiteColor()]
UIBarButtonItem.appearance().setTitleTextAttributes([NSFontAttributeName: UIFont.boldSystemFontOfSize(15),NSForegroundColorAttributeName: UIColor.whiteColor()], forState: UIControlState.Normal)
oc:
#pragma mark - 设置全局返回按钮,无文字
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60)
forBarMetrics:UIBarMetricsDefault];
如果需要设置导航栏颜色,使barItem颜色也被渲染了,可以这样设置(就可以保证barItem里面图片的颜色不被渲染了)
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage: [[UIImage imageNamed: @"xiaoxi_icon"] imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal] style: UIBarButtonItemStylePlain target: self action: @selector(a)];
如果导航栏与view出现了空隙。需要把系统默认设置空隙值关掉
#pragma 设置控制器,出现默认知道空隙
// self.automaticallyAdjustsScrollViewInsets = NO;
设置全局导航栏颜色,标题大小和UIBarButtonItem字体大小
