iOS 改变状态栏颜色

在info.plist中将View controller-based status bar appearance设置为true

在ViewController中设置

- (UIStatusBarStyle)preferredStatusBarStyle {
    return UIStatusBarStyleDefault;
}

iOS 13 dark mode禁用

- (UIStatusBarStyle)preferredStatusBarStyle {
    if (@available(iOS 13.0, *)) {
        if (self.traitCollection.userInterfaceStyle == UIUserInterfaceStyleDark) {
            return UIStatusBarStyleDarkContent;
        }
    }
    return UIStatusBarStyleDefault;
}
