我正在使用iOS 6的xcode 4.5.2中的phonegap 2.7.0 Web应用程序。在我的Web应用程序中包含六秒钟的视频录制选项。因此，我从“https://github.com/piemonte/PBJVision”完成了此过程。
现在，我正在尝试使用CDVPlugin将本机iOS与Phonegap混合。因为我的homescreen.html中有一个图像(相机图标)，所以当我单击该图像时，图像标签onclick()会触发并在PBJViewController.m文件中调用-(void)_setup()方法。因此，mainscreen.html被隐藏并显示带有某些自定义设计的相机选项。
因此，我将PBJViewController.h和PBJViewController.m，PBJStrobeView.h和PBJStrobeView.m，PBJVisionUtilities.h和PBJVisionUtilities.m以及最后的PBJVision.h和PBJVison.m文件放在了plugins文件夹中。
然后，我创建一个JavaScript文件并将其命名为PBJViewController.js并添加到www文件夹中。
PBJViewController.js
function PBJViewController()
{
}
loadingalert.prototype._setup = function()
{
//this.resultCallback(res);
cordova.exec("PBJViewController._setup");
}
cordova.addConstructor(function() {
if(!window.plugins)
{
window.plugins = {};
}
//window.plugins.loadingalert = new PBJViewController();
window.loadingalert = new PBJViewController();
});
然后，我在homescreen.html文件的video()函数中编写了调用代码。
homescreen.htm l
function video()
{
alert("video function");
$('#loader').hide();
$('#divcontroller').hide();
$('#menuid').hide();
$('#home_feeds').hide();
loadingalert._setup();
//window.plugins.loadingalert._setup();
//objloading._setup();
//window.location = "js-call:myObjectiveCFunction";
//window.location.href='video.html?user_id='+userid+'&fb_token='+getValue("fb_token");
}
我在PBJViewController.h文件中做了一些更改
PBJViewController.h
#import <UIKit/UIKit.h>
#import <Cordova/CDVPlugin.h>
@interface PBJViewController : CDVPlugin <UIWebViewDelegate>
{
IBOutlet UIWebView *webView;
}
-(void)_setup:(NSMutableArray*)paramArray withDict:(NSMutableDictionary*)options;
@end
并且在PBJViewcontroller.m文件中
#import "PBJViewController.h"
#import "PBJVision.h"
#import "PBJStrobeView.h"
#import <Cordova/CDVPlugin.h>
#import <AssetsLibrary/AssetsLibrary.h>

UIEdgeInsets hitTestEdgeInsets = UIEdgeInsetsMake(-35, -35, -35, -35);
CGRect hitFrame = UIEdgeInsetsInsetRect(relativeFrame, hitTestEdgeInsets);
return CGRectContainsPoint(hitFrame, point);
}

在这里，我面临警告消息“CDVPlugin”可能无法响应“viewWillAppear:”，因为我将CDVPlugin替换为UIViewController“@interface PBJViewController:CDVPlugin”
我在config.xml文件中包含了插件的名称和值，
config.xml
这些是我的示例代码之一。我的问题是直到无法获得所需的输出。
请给出一些建议或结果。
最佳答案
您可以尝试调用类似cordova.exec(null, null, "PBJViewController", "_setup", [])的插件方法
关于javascript - 我无法使用CDVPlugin从phonegap 2.7.0中的javascript访问 native iOS？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/18777766/
