Question

我是 phone 的新人 gap.I 正在尝试为 Phone-gap iphone 实施 Instagram 登录。 facinfg调用plugin.cordova2.9.0版本方法的一些问题我using.Here如下代码：

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_AUTHURL                               @"https://api.instagram.com/oauth/authorize/"

@subir,

您使用的是过时的代码示例。

你已经中了：

Top Mistakes by Developers new to Cordova/Phonegap

您已达到 11. 和 12.

11。您现在需要从 NPM 获取插件。

有关采购插件的规则可能相当混乱。最好的办法是阅读下面的博客 posts。使用 CLI 的开发人员可以从 github 获取资源，再次查看博客 post.

2015-10-09 - 在没有公告、推文或博客的情况下，存储库在计划前整整一周发生了变化。我什么也做不了，只能抱怨....这真烦人。
