iOS日志-设置导航栏背景及字体颜色

返回item颜色

[self.navigationController.navigationBarsetTintColor:[UIColor whiteColor]];

导航栏背景

[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"nav_bg"] forBarMetrics:UIBarMetricsDefault];

[self.navigationController.navigationBar setBackgroundImage:[UIImage jk_imageWithColor:UIColor.whiteColor] forBarMetrics:UIBarMetricsDefault];

导航栏透明度

[self.navigationController.navigationBar.barStyle=UIBarStyleBlackTranslucent;[self.navigationController.navigationBarsetBackgroundImage:[UIImageimageNamed:@"o+x"] forBarMetrics:UIBarMetricsCompact];

不加会有横线

[self.navigationController.navigationBar setValue:@(0) forKeyPath:@"backgroundView.alpha"];
 self.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;

修改字体颜色及字体大小

NSDictionary *titleTextAttributes = @{
                                          NSForegroundColorAttributeName : kUIColorDarkNavy,
                                          NSFontAttributeName : [UIFont fontWithName:@"PingFangSC-Medium" size:16],
                                          };
    
 self.navigationController.navigationBar.titleTextAttributes = titleTextAttributes;

{
    [super viewWillAppear:animated];
    
    [self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
    
    [self.navigationController.navigationBar setShadowImage:[UIImage new]];
}

{
    [super viewWillDisappear:animated];
