如何在iOS 7上更改状态栏的背景颜色和文字颜色?
我目前的应用程序运行在iOS 5和6上。
导航栏的颜色为橙色,状态栏的背景颜色为白色,为白色。 但是,当我在iOS 7上运行相同的应用程序时,我发现状态栏看起来很透明,与导航栏相同的橙色背景色和状态栏文本颜色是黑色的。
由于这个我不能区分状态栏和导航栏。
如何使状态栏看起来与iOS 5和iOS 6中的状态栏相同,即黑色背景颜色和白色文本颜色? 我怎样才能做到这一点编程?
我不得不尝试寻找其他方法。 这不涉及窗口上的addSubview
。 因为当键盘出现时我正在向上移动窗口。
目标C
- (void)setStatusBarBackgroundColor:(UIColor *)color { UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"]; if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) { statusBar.backgroundColor = color; } }
迅速
func setStatusBarBackgroundColor(color: UIColor) { guard let statusBar = UIApplication.sharedApplication().valueForKey("statusBarWindow")?.valueForKey("statusBar") as? UIView else { return } statusBar.backgroundColor = color }
Swift 3
func setStatusBarBackgroundColor(color: UIColor) { guard let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView else { return } statusBar.backgroundColor = color }
调用这个表单application:didFinishLaunchingWithOptions
为我工作。
注意我们在这个逻辑应用程序商店中有一个应用程序。 所以我想应用程序商店的政策是可以的。

使用风险自负。 形成评论者@Sebyddd
我有一个应用程序被拒绝的原因,而另一个被接受的很好。 他们确实认为它是私人的API使用,所以你在审查过程中运气:) – Sebyddd
转到您的应用程序info.plist
1)将View controller-based status bar appearance
为NO
2)将Status bar style
UIStatusBarStyleLightContent
为UIStatusBarStyleLightContent
然后转到您的应用程序委托并粘贴以下代码设置您的Windows的RootViewController。
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending) if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) { UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,[UIScreen mainScreen].bounds.size.width, 20)]; view.backgroundColor=[UIColor blackColor]; [self.window.rootViewController.view addSubview:view]; }
希望它有帮助。
1)在plist中设置UIViewControllerBasedStatusBarAppearance为YES
2)在viewDidLoad中做一个[self setNeedsStatusBarAppearanceUpdate];
3)添加以下方法:
-(UIStatusBarStyle)preferredStatusBarStyle{ return UIStatusBarStyleLightContent; }
更新:
还要检查开发人员指南到这个ios-7-status-bar
处理iOS 7状态栏的背景颜色时,有两种情况
案例1:使用导航栏进行查看
在这种情况下,请在viewDidLoad方法中使用以下代码
UIApplication *app = [UIApplication sharedApplication]; CGFloat statusBarHeight = app.statusBarFrame.size.height; UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, -statusBarHeight, [UIScreen mainScreen].bounds.size.width, statusBarHeight)]; statusBarView.backgroundColor = [UIColor yellowColor]; [self.navigationController.navigationBar addSubview:statusBarView];
情况2:没有导航栏的视图
在这种情况下,请在viewDidLoad方法中使用以下代码
UIApplication *app = [UIApplication sharedApplication]; CGFloat statusBarHeight = app.statusBarFrame.size.height; UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, statusBarHeight)]; statusBarView.backgroundColor = [UIColor yellowColor]; [self.view addSubview:statusBarView];

在iOS 7中,状态栏没有背景,因此如果您在背后放置黑色20像素高的视图,则会获得与iOS 6相同的结果。
另外,您也可以阅读“ iOS 7用户界面过渡指南”以获取有关该主题的更多信息。
写在你的ViewDidLoad方法:
if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) { self.edgesForExtendedLayout=UIRectEdgeNone; self.extendedLayoutIncludesOpaqueBars=NO; self.automaticallyAdjustsScrollViewInsets=NO; }
它修复了我的状态栏颜色,还有一些其他的UI错位。
只要添加到Shahid的答案 – 你可以说明方向的变化或不同的设备使用(iOS7 +):
- (BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { ... //Create the background UIView* statusBg = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.window.frame.size.width, 20)]; statusBg.backgroundColor = [UIColor colorWithWhite:1 alpha:.7]; //Add the view behind the status bar [self.window.rootViewController.view addSubview:statusBg]; //set the constraints to auto-resize statusBg.translatesAutoresizingMaskIntoConstraints = NO; [statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeTop multiplier:1.0 constant:0.0]]; [statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeLeft multiplier:1.0 constant:0.0]]; [statusBg.superview addConstraint:[NSLayoutConstraint constraintWithItem:statusBg attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual toItem:statusBg.superview attribute:NSLayoutAttributeRight multiplier:1.0 constant:0.0]]; [statusBg.superview addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[statusBg(==20)]" options:0 metrics:nil views:NSDictionaryOfVariableBindings(statusBg)]]; [statusBg.superview setNeedsUpdateConstraints]; ... }
为背景,您可以轻松地添加一个视图,如在示例中:
UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,320, 20)]; view.backgroundColor=[UIColor colorWithRed:0/255.0 green:0/255.0 blue:0/255.0 alpha:0.1]; [navbar addSubview:view];
“navbar”是一个UINavigationBar。
我希望它可以帮助你!
更改状态栏的背景颜色:Swift:
let proxyViewForStatusBar : UIView = UIView(frame: CGRectMake(0, 0,self.view.frame.size.width, 20)) proxyViewForStatusBar.backgroundColor=UIColor.whiteColor() self.view.addSubview(proxyViewForStatusBar)
这是一个总的,复制和粘贴的解决scheme,与一个
绝对正确的解释
涉及的每一个问题。

对于关于keyPath statusBarWindow.statusBar
的惊人的发现。 好的。
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { // handle the iOS bar! // >>>>>NOTE<<<<< // >>>>>NOTE<<<<< // >>>>>NOTE<<<<< // "Status Bar Style" refers to the >>>>>color of the TEXT<<<<<< of the Apple status bar, // it does NOT refer to the background color of the bar. This causes a lot of confusion. // >>>>>NOTE<<<<< // >>>>>NOTE<<<<< // >>>>>NOTE<<<<< // our app is white, so we want the Apple bar to be white (with, obviously, black writing) // make the ultimate window of OUR app actually start only BELOW Apple's bar.... // so, in storyboard, never think about the issue. design to the full height in storyboard. let h = UIApplication.shared.statusBarFrame.size.height let f = self.window?.frame self.window?.frame = CGRect(x: 0, y: h, width: f!.size.width, height: f!.size.height - h) // next, in your plist be sure to have this: you almost always want this anyway: // <key>UIViewControllerBasedStatusBarAppearance</key> // <false/> // next - very simply in the app Target, select "Status Bar Style" to Default. // Do nothing in the plist regarding "Status Bar Style" - in modern Xcode, setting // the "Status Bar Style" toggle simply sets the plist for you. // finally, method A: // set the bg of the Apple bar to white.

您可以在应用程序启动期间或视图控制器的viewDidLoad期间为状态栏设置背景颜色。
extension UIApplication { var statusBarView: UIView? { return value(forKey: "statusBar") as? UIView } } // Set upon application launch, if you've application based status bar class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { UIApplication.shared.statusBarView?.backgroundColor = UIColor.red return true } } or // Set it from your view controller if you've view controller based statusbar class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() UIApplication.shared.statusBarView?.backgroundColor = UIColor.red } }
结果如下:
这里是关于状态栏变化的Apple指南/说明 。 状态栏只允许黑暗和光亮(同时和黑色)。
这里是 – 如何改变状态栏的风格:
如果你想设置状态栏风格,应用程序级别,然后在你的`.plist'文件中设置UIViewControllerBasedStatusBarAppearance
为NO
。
如果你想设置状态栏风格,在视图控制器级别,然后按照下列步骤:
- 如果您只需要在UIViewController级别设置状态栏样式,请将
.plist
文件中的UIViewControllerBasedStatusBarAppearance
设置为YES
。 -
在viewDidLoad添加函数 –
setNeedsStatusBarAppearanceUpdate
-
在视图控制器中覆盖preferredStatusBarStyle。
–
override func viewDidLoad() { super.viewDidLoad() self.setNeedsStatusBarAppearanceUpdate() } override var preferredStatusBarStyle: UIStatusBarStyle { return .lightContent }
在iOS 9上swift 2.0的情况下
将下面的内容放在应用程序委托下,在didFinishLaunchingWithOptions下面:
let view: UIView = UIView.init(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.size.width, 20)) view.backgroundColor = UIColor.blackColor() //The colour you want to set view.alpha = 0.1 //This and the line above is set like this just if you want the status bar a darker shade of the colour you already have behind it. self.window!.rootViewController!.view.addSubview(view)
iTroid23解决scheme为我工作。 我错过了Swift解决scheme。 所以也许这是有帮助的:
1)在我的plist中,我不得不补充一点:
<key>UIViewControllerBasedStatusBarAppearance</key> <true/>
2)我不需要调用“setNeedsStatusBarAppearanceUpdate”。
3)在迅速,我不得不添加到我的UIViewController:
override func preferredStatusBarStyle() -> UIStatusBarStyle { return UIStatusBarStyle.LightContent }
对于条形颜色:为条形提供自定义背景图像。
对于文本颜色:使用iOS中关于文本处理中的信息
如果您使用的是UINavigationController
,则可以使用如下所示的扩展名:
extension UINavigationController { private struct AssociatedKeys { static var navigationBarBackgroundViewName = "NavigationBarBackground" } var navigationBarBackgroundView: UIView? { get { return objc_getAssociatedObject(self, &AssociatedKeys.navigationBarBackgroundViewName) as? UIView } set(newValue) { objc_setAssociatedObject(self, &AssociatedKeys.navigationBarBackgroundViewName, newValue, .OBJC_ASSOCIATION_RETAIN) } } func setNavigationBar(hidden isHidden: Bool, animated: Bool = false) { if animated { UIView.animate(withDuration: 0.3) { self.navigationBarBackgroundView?.isHidden = isHidden } } else { navigationBarBackgroundView?.isHidden = isHidden } } func setNavigationBarBackground(color: UIColor, includingStatusBar: Bool = true, animated: Bool = false) { navigationBarBackgroundView?.backgroundColor = UIColor.clear navigationBar.backgroundColor = UIColor.clear navigationBar.barTintColor = UIColor.clear let setupOperation = { if includingStatusBar { self.navigationBarBackgroundView?.isHidden = false if self.navigationBarBackgroundView == nil { self.setupBackgroundView() } self.navigationBarBackgroundView?.backgroundColor = color } else { self.navigationBarBackgroundView?.isHidden = true self.navigationBar.backgroundColor = color } } if animated { UIView.animate(withDuration: 0.3) { setupOperation() } } else { setupOperation() } } private func setupBackgroundView() { var frame = navigationBar.frame frame.origin.y = 0 frame.size.height = 64 navigationBarBackgroundView = UIView(frame: frame) navigationBarBackgroundView?.translatesAutoresizingMaskIntoConstraints = true navigationBarBackgroundView?.autoresizingMask = [.flexibleWidth, .flexibleBottomMargin] navigationBarBackgroundView?.isUserInteractionEnabled = false view.insertSubview(navigationBarBackgroundView!, aboveSubview: navigationBar) } }
它基本上使导航栏背景透明,并使用另一个UIView作为背景。 您可以调用导航控制器的setNavigationBarBackground
方法,将导航栏背景颜色与状态栏一起设置。
请记住,如果要隐藏导航栏,则必须在扩展中使用setNavigationBar(hidden: Bool, animated: Bool)
方法,否则用作背景的视图仍将可见。
请试试这个。 在appdelegate类“didFinishLaunchingWithOptions”函数中使用此代码
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; [application setStatusBarHidden:NO]; UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"]; if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) { statusBar.backgroundColor = [UIColor blackColor]; }
