我如何更改导航栏的背景颜色

发布于 2024-08-10 03:42:45 字数 177 浏览 5 评论 0原文

在我的导航栏中，我在左侧和右侧位置有两个按钮，在导航标题处有一个 segmentetControll 视图。我想将导航栏的背景颜色更改为黑色，但其上项目的颜色将是另一种颜色。我该怎么做？我尝试将导航栏的色调颜色更改为黑色。但我表明，segmentedControll 和导航栏上的按钮的颜色也更改为黑色。

提前致谢。

尝试将对象设置为导航栏的子视图。

设置色调颜色

UINavigationController *theNavigationController = [[UINavigationController alloc] initWithRootViewController: aFeedControler]; 
theNavigationController.navigationBar.tintColor = [UIColor blackColor];

将segmentedControl添加为viewControllers中的子视图，如下所示：

 UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:[UIImage imageNamed:@"segment_check.png"],
[UIImage imageNamed:@"segment_search.png"],
[UIImage imageNamed:@"segment_tools.png"], nil]];
    CGRect frame = CGRectMake(0,0, 200,40);
    segmentedControl.frame = frame;
    [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
    segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
    segmentedControl.selectedSegmentIndex = 1;  
    self.navigationItem.titleView  = segmentedControl;

对于按钮，您应该尝试创建UIButtons而不是UIBarButtonsItems并将它们添加为子视图。如果您创建 UIBarButtonsItems 并像这样添加它们 self.navigationItem.rightBarButtonItem = tempButton;你会得到你所看到的效果。

如果您将它们添加为子视图，您不应该遇到您提到的问题..希望它有帮助。

try to set the objects as subviews to the navigationBar.

Set the tint color

UINavigationController *theNavigationController = [[UINavigationController alloc] initWithRootViewController: aFeedControler]; 
theNavigationController.navigationBar.tintColor = [UIColor blackColor];

Add the segmentedControl as a subview in the viewControllers like this:

 UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:[UIImage imageNamed:@"segment_check.png"],
[UIImage imageNamed:@"segment_search.png"],
[UIImage imageNamed:@"segment_tools.png"], nil]];
    CGRect frame = CGRectMake(0,0, 200,40);
    segmentedControl.frame = frame;
    [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
    segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
    segmentedControl.selectedSegmentIndex = 1;  
    self.navigationItem.titleView  = segmentedControl;

For the buttons you should try creating UIButtons not UIBarButtonsItems and add them as subviews also. If you create UIBarButtonsItems and add them like this self.navigationItem.rightBarButtonItem = tempButton; you will get the effect that you saw.

if you add them as subviews you shouldn't have the problem you mentioned.. hope it helps.

您在导航栏中有一个名为“tintColor”的属性。您可以将其值设置为任何颜色。

 UINavigationController *_navigationController = [[UINavigationController alloc] initWithRootViewController: _viewController]; 

 either this
 _navigationController.navigationBar.tintColor = [UIColor blackColor];

 OR 
_navigationController.navigationBar.barStyle=UIBarStyleBlack;



 Now about right and left buttons:
 UIButton *btnLeft=[UIButton buttonWithType:UIButtonTypeCustom];
 btnLeft.frame=CGRectMake(0.0, 5.0, 50.0, 30.0);
 btnLeft.backgroundColor=[UIColor RedColor];
 btnLeft.layer.borderColor=[UIColor whiteColor].CGColor;
 btnLeft.titleLabel.textColor=[UIColor blackColor];
 btnLeft.titleLabel.font=[UIFont boldSystemFontOfSize:10.0];

 _navigationController.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc]initWithCustomView:btnLeft];



 similary you can add right bar button
