Instagram login in phonegap ios

我是电话间隙的新手。我正在尝试为Phone-gapiphone实现Instagram登录。fcinfg 调用我正在使用的插件.cordova2.9.0 版本的方法的一些问题。下面是以下代码：

CDVInstagram插件.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
