I can't access native iOS from javascript in phonegap 2.7.0 using CDVPlugin?
I'm doing phonegap 2.7.0 web application in xcode 4.5.2 for iOS 6. In my web application contains video recording option with six seconds duration. So I done this process from "https://github.com/piemonte/PBJVision".
Now I'm trying to hybrid native iOS with Phonegap by using CDVPlugin. Because I have an image(camera icon) in homescreen.html, when I click the image, the image tag onclick() fire and call the -(void) _setup() method in PBJViewController.m file. So the mainscreen.html was hide and show the camera option with some custom design's.
So, I put PBJViewController.h & PBJViewController.m, PBJStrobeView.h & PBJStrobeView.m, PBJVisionUtilities.h & PBJVisionUtilities.m, and last PBJVision.h & PBJVison.m files in plugins folder.
Then I create a JavaScript files and named as PBJViewController.js and add into the www folder.
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();
});
And then I wrote calling code in function video() at homescreen.html file.
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");
}
And I made some changes in PBJViewController.h file
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
And In PBJViewcontroller.m file
#import "PBJViewController.h"
#import "PBJVision.h"
#import "PBJStrobeView.h"
#import <Cordova/CDVPlugin.h>
#import <AssetsLibrary/AssetsLibrary.h>
#import <MediaPlayer/MediaPlayer.h>

@end
@implementation UIButton (ExtendedHit)
- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
CGRect relativeFrame = self.bounds;
UIEdgeInsets hitTestEdgeInsets = UIEdgeInsetsMake(-35, -35, -35, -35);
CGRect hitFrame = UIEdgeInsetsInsetRect(relativeFrame, hitTestEdgeInsets);
return CGRectContainsPoint(hitFrame, point);
}

}
Here I face the warning message 'CDVPlugin' may not respond to 'viewWillAppear:' because I replace the CDVPlugin for UIViewController "@interface PBJViewController : CDVPlugin "
And I include the plugins name and value in config.xml file, there is,
config.xml
These are one of my sample code. My problem is till not get the desired output.
Kindly give some suggestion or result.
你可以尝试像这样调用插件方法cordova.exec(null, null, "PBJViewController", "_setup", [])
