在Phonegap中获取当前的UIViewController

我正在通过PhoneGap插件加载一个应用程序(通过嵌入式框架) 现在,我正在尝试将当前的UIViewController传递给 FlashizFacade 对象的 parentViewController 属性。

当我执行我的应用程序时,在分配 self 时,我在调试控制台中收到此错误:

  
    

2012-09-10 13:01:43.663 gTicketSales [2805:16a03] - [FlashizPlugin navigationController]:无法识别的选择器发送到实例0x91925e0

         

2012-09-10 13:01:43.665 gTicketSales [2805:16a03] *** WebKit在webView中丢弃了一个未捕获的异常:decisionPolicyForNavigationAction:request:frame:decisionListener:delegate:<NSInvalidArgumentException> - [FlashizPlugin navigationController ]:无法识别的选择器发送到实例0x91925e0

  

分配 self.viewController 时:

  
    
      

2012-09-10 14:31:21.455 gTicketSales [3693:16a03] *** WebKit在webView中丢弃了一个未捕获的异常:decisionPolicyForNavigationAction:request:frame:decisionListener:delegate:<Wrong parentViewController specified>当使用非模态显示,parentViewController必须是UIViewController的实例,并且已分配有效的navigationController

    
  

我试过了:

facade.parentViewController = self;
facade.parentViewController = self.viewController;

我的.h文件

#import <Cordova/CDVPlugin.h>
#import <FlashizPaymentLib/FlashizFacade.h>

@interface FlashizPlugin : CDVPlugin <FlashizPaymentDelegate> {}

@property (nonatomic, retain) FlashizFacade* flashizFacade;
- (void) openFlashiz:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options;

@end

我的.m文件

#import "FlashizPlugin.h"
@implementation FlashizPlugin
@synthesize flashizFacade;

- (void) openFlashiz:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options     {


NSLog(@"Flashiz Payment Opening...");

NSString *callbackId = [arguments pop];
NSString *invoiceId = [arguments objectAtIndex:0];

FlashizFacade* facade = [[FlashizFacade alloc] initWithEnvironment:FE_TEST];
facade.parentViewController = self;
facade.delegate = self;
self.flashizFacade = facade;
[facade executePaymentForInvoiceId:invoiceId];
[facade release];

CDVPluginResult *result;

result = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString:@"Flashiz Payment Executed..."];
[self writeJavascript:[result toSuccessCallbackString:callbackId]];

}


@end

在AppDelegate.h上

@property (nonatomic, strong) UINavigationController *navigationController;
AppDelegate.m上的

application didFinishLaunchingWithOptions

上更改此行
self.window.rootViewController = self.viewController;

这个

    UINavigationController *aNavigationController = [[UINavigationController alloc]                                                  initWithRootViewController:self.viewController];
    self.navigationController = aNavigationController;
    self.window.rootViewController = self.navigationController;

在我的项目崩溃,因为我没有ConnectionViewController,我认为我没有正确包含框架,因为我不知道如何处理Resources文件夹,但我认为它应该适合你。

编辑:我刚刚包含了资源文件夹,它正在运行!!!

如果您不希望phonegap的视图控制器上的navigationBar放入viewDidLoad MainViewController.m

self.navigationController.navigationBar.hidden = YES;
