修改状态栏的颜色 iOS

需求：全局黑色状态栏，某个页面白色状态栏

有两种实现方式：

第一种：全局设置状态栏颜色

1.在 info.plist 添加View controller-based status bar appearance 设置为NO

 

 

2 在AppDelegate.m 的方法中如下设置,默认会显示黑色

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    //设置全局状态栏颜色为黑色

    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleDefault;

    //设置全局状态栏颜色为白色

    // [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

    return YES;

}

3.在其他页面设置状态栏的颜色

-(void)viewWillAppear:(BOOL)animated{

    [super viewWillAppear:animated];

    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

}

 

-(void)viewWillDisappear:(BOOL)animated{

    [super viewWillDisappear:animated];

    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleDefault;

}

第二种：局部设置状态栏颜色

1.在 info.plist 添加View controller-based status bar appearance 设置为YES

2.控制器基类里

.h里

// 设置当前控制器的状态栏style

@property(assign, nonatomic) BOOL mWhiteStausBar;

.m里

- (void)setMWhiteStausBar:(BOOL)mWhiteStausBar

{

    if (_mWhiteStausBar == mWhiteStausBar) {

        return;

    }

    _mWhiteStausBar = mWhiteStausBar;

    

    [self setNeedsStatusBarAppearanceUpdate];

}

 

- (UIStatusBarStyle)preferredStatusBarStyle{

    return self.mWhiteStausBar ? UIStatusBarStyleLightContent:UIStatusBarStyleDefault;

}

某个页面这样调用

self.mWhiteStausBar = YES;
