Javascript 在phonegap ios中登录Instagram

我是phone gap的新手。我正在尝试为phone gap iphone实现Instagram登录。facinfg调用我正在使用的plugin.cordova2.9.0版本的方法时遇到一些问题。以下是代码：

CDVInstagramPlugin.js

function startLogin(response)
{`enter code here`
   cordova.exec(onInstaComplete, onInstaNotComplete, 'LoginViewController', 'initWithWebView', []);

}


//  LoginViewController.h


#import <UIKit/UIKit.h>

@interface LoginViewController : UIViewController<UIWebViewDelegate>
{
    IBOutlet UIWebView *loginWebView;
    IBOutlet UIActivityIndicatorView* loginIndicator;
    IBOutlet UILabel *loadingLabel;
}
@property(strong,nonatomic)NSString *typeOfAuthentication;
-(void)startLogin;
@end




  LoginViewController.m
//  InstagramUnsignedAuthentication


#import "LoginViewController.h"
#import "AppDelegate.h"

#define INSTAGRAM_ACCESS_TOKEN                          @"access_token"
#define INSTAGRAM_SCOPE                                 @"likes+comments+relationships"
