Cordova IOS插件：更改状态栏颜色

Question

我正在尝试向我的Cordova插件添加更改状态栏颜色的选项。 （我想在我的插件中执行此操作，而不要为此使用其他插件）。

我有以下代码可用于我创建的ios应用程序：

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

bool isDakMode = false;

- (UIStatusBarStyle)preferredStatusBarStyle {
    if (isDakMode == false) {
        return UIStatusBarStyleDefault;
       } else {
          return UIStatusBarStyleLightContent;
       }
}

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}


- (IBAction)changeMe:(id)sender {
    if (isDakMode == false) {
        isDakMode = true;
    } else {
        isDakMode = false;
    }
    [self setNeedsStatusBarAppearanceUpdate];
}
@end

我无法在Cordova插件上使用它（无法调用preferredStatusBarStyle）。

这是我的Cordova插件代码：

#import "HWPHello.h"


@implementation HWPHello

- (void)greet:(CDVInvokedUrlCommand*)command
{
    NSString* style = [[command arguments] objectAtIndex:0];

    if ([style isEqualToString:@"DARK"]) {
        [self setStyleForStatusBar:UIStatusBarStyleDefault];
    } else {
         [self setStyleForStatusBar:UIStatusBarStyleLightContent];
    }
    NSString* msg = [NSString stringWithFormat: @"Status bar is now in %@ color", style];

    CDVPluginResult* result = [CDVPluginResult
                               resultWithStatus:CDVCommandStatus_OK
                               messageAsString:msg];

    [self.commandDelegate sendPluginResult:result callbackId:command.callbackId];
}


- (void) setStyleForStatusBar:(UIStatusBarStyle)style
{
        myStatusBarStyle = style;
        [self refreshStatusBarAppearance];
}


- (void) refreshStatusBarAppearance
{
    SEL sel = NSSelectorFromString(@"setNeedsStatusBarAppearanceUpdate");
    if ([self.viewController respondsToSelector:sel]) {
        [self.viewController performSelector:sel withObject:nil];
    }
}


- (UIStatusBarStyle)preferredStatusBarStyle
{
    return myStatusBarStyle;
}
@end

我想念什么？ 谢谢
