ios 状态栏statusBar的背景颜色和字体颜色设置

假如我想让状态栏颜色设置成红色，字体仍为黑色，可以在需要显示的那一页进行如下设置：(最好写在viewWillAppear里面)

//设置状态栏颜色 - (void)setStatusBarBackgroundColor:(UIColor *)color { UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"]; if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) { statusBar.backgroundColor = color; } } - (void)viewDidLoad { [super viewDidLoad]; [self setStatusBarBackgroundColor:[UIColor redColor]]; self.view.backgroundColor = [UIColor yellowColor]; }

- (UIStatusBarStyle)preferredStatusBarStyle{
    return UIStatusBarStyleLightContent;
}

//设置字体颜色 - (UIStatusBarStyle)preferredStatusBarStyle{ return UIStatusBarStyleLightContent;//白色 } //设置状态栏颜色 - (void)setStatusBarBackgroundColor:(UIColor *)color { UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"]; if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) { statusBar.backgroundColor = color; } } //！！！重点在viewWillAppear方法里调用下面两个方法 -(void)viewWillAppear:(BOOL)animated{ [self preferredStatusBarStyle]; [self setStatusBarBackgroundColor:[UIColor redColor]]; } - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor yellowColor]; }

 

//设置状态栏颜色
- (void)setStatusBarBackgroundColor:(UIColor *)color {
    
    UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];
    if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) {
        statusBar.backgroundColor = color;
    }
}
-(void)viewWillAppear:(BOOL)animated{
 
    [self setStatusBarBackgroundColor:[UIColor redColor]];
     [UIApplication sharedApplication].statusBarStyle=UIStatusBarStyleLightContent;
}
--->！！！同时别忘了在info plist里面将View controller-based status bar appearance设置成NO，（默认是YES）

现在基本的设备都适配ios7以上设备，默认的状态栏字体颜色是黑色
[UIApplicationsharedApplication].statusBarStyle=UIStatusBarStyleDefault;
