我目前的应用程序在iOS 5和6上运行。
导航栏为橙色,状态栏为黑色背景颜色,白色为文本颜色。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是透明的,具有与导航栏相同的橙色背景颜色,状态栏文本颜色为黑色。
由于这个原因,我无法区分状态栏和导航栏。
如何使状态栏看起来与iOS 5和6中的状态相同,即黑色背景颜色和白色文本颜色?我该如何以编程方式执行此操作?
我不得不尝试寻找其他方法。哪个不涉及addSubview
在窗口。因为当键盘呈现时我正在向上移动窗口。
- (void)setStatusBarBackgroundColor:(UIColor *)color {
UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];
if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) {
statusBar.backgroundColor = color;
}
}
func setStatusBarBackgroundColor(color: UIColor) {
guard let statusBar = UIApplication.sharedApplication().valueForKey("statusBarWindow")?.valueForKey("statusBar") as? UIView else {
return
}
statusBar.backgroundColor = color
}
func setStatusBarBackgroundColor(color: UIColor) {
guard let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView else { return }
statusBar.backgroundColor = color
}
打电话给这个表格application:didFinishLaunchingWithOptions
为我工作。
注:我们在应用程序商店中有一个具有此逻辑的应用程序。所以我想应用商店政策是可以的。

关于keyPath statusBarWindow.statusBar
的惊人发现。好的。

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:

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)
斯威夫特4:
//更改状态栏背景颜色
let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
statusBar?.backgroundColor = UIColor.red
对于iOS 9上的swift 2.0
将以下内容放在app委托中,位于didFinishLaunchingWithOptions下:
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解决方案适合我。我错过了Swift解决方案。所以这可能有用:
1)在我的plist中,我不得不添加:
<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>
2)我不需要调用“setNeedsStatusBarAppearanceUpdate”。
3)在swift中我必须将它添加到我的UIViewController:
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return UIStatusBarStyle.LightContent
}
我成功地自定义了StatusBar颜色非常简单,在方法中添加了AppDelegate.cs
文件:
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
下一个代码:
UIView statusBar = UIApplication.SharedApplication.ValueForKey(new NSString("statusBar")) as UIView;
if (statusBar!=null && statusBar.RespondsToSelector(new Selector("setBackgroundColor:")))
{
statusBar.BackgroundColor = Color.FromHex(RedColorHex).ToUIColor();
}
所以你得到这样的东西:

对于条形颜色:您为条形图提供自定义背景图像。
对于文本颜色:使用About Text Handling in iOS中的信息
如果你使用的是UINavigationController
,你可以使用这样的扩展名:
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,当您要隐藏导航栏时,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然可见。
斯威夫特4
在Info.plist
添加此属性
查看基于控制器的状态栏外观为NO
然后在AppDelegate
里面的didFinishLaunchingWithOptions
添加这些代码行
UIApplication.shared.isStatusBarHidden = false
UIApplication.shared.statusBarStyle = .lightContent
在Swift 5和Xcode 10.2中
DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + Double(Int64(0.1 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC), execute: {
//Set status bar background colour
let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
statusBar?.backgroundColor = UIColor.red
//Set navigation bar subView background colour
for view in controller.navigationController?.navigationBar.subviews ?? [] {
view.tintColor = UIColor.white
view.backgroundColor = UIColor.red
}
})
这里我修复了状态栏背景颜色和导航栏背景颜色。如果你不想要导航栏颜色评论它。
转到你的应用程序info.plist
1)将View controller-based status bar appearance
设置为NO
2)将Status bar style
设为UIStatusBarStyleLightContent
然后转到您的应用程序委托并将以下代码粘贴到您设置Windows的RootViewController的位置。
#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];
}
希望能帮助到你。
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];
}
1)在plist中将UIViewControllerBasedStatusBarAppearance设置为YES
2)在viewDidLoad做一个[self setNeedsStatusBarAppearanceUpdate];
3)添加以下方法:
-(UIStatusBarStyle)preferredStatusBarStyle{
return UIStatusBarStyleLightContent;
}
在iOS 7中处理状态栏的背景颜色时,有两种情况
案例1:使用导航栏查看
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];
案例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];

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:
这是关于状态栏更改的Apple Guidelines/Instruction。状态栏中仅允许黑暗和浅色(同时为黑色)。
这是 - 如何更改状态栏样式:
如果要设置状态栏样式,应用程序级别,然后在`.plist'文件中将UIViewControllerBasedStatusBarAppearance
设置为NO
。
如果要设置状态栏样式,请在视图控制器级别执行以下步骤:
UIViewControllerBasedStatusBarAppearance
文件中将YES
设置为.plist
。setNeedsStatusBarAppearanceUpdate
-
override func viewDidLoad() {
super.viewDidLoad()
self.setNeedsStatusBarAppearanceUpdate()
}
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
在iOS 7中,状态栏没有背景,因此如果您在其后面放置一个黑色的20px高视图,您将获得与iOS 6相同的结果。
您也可以阅读iOS 7 UI Transition Guide以获取有关该主题的更多信息。
在ViewDidLoad方法中写下这个:
if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) {
self.edgesForExtendedLayout=UIRectEdgeNone;
self.extendedLayoutIncludesOpaqueBars=NO;
self.automaticallyAdjustsScrollViewInsets=NO;
}
它在一定程度上修复了我和其他UI错位的状态栏颜色。
只是为了添加Shahid的答案 - 您可以使用此方法考虑方向更改或不同的设备(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];
...
}
对于背景,您可以轻松添加视图,例如:
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];
其中“navbar”是UINavigationBar。
