iOS 6 用の xcode 4.5.2 で phonegap 2.7.0 Web アプリケーションを実行しています。私の Web アプリケーションには、6 秒間のビデオ録画オプションが含まれています。というわけで、「 https://github.com/piemonte/PBJVision 」からこのプロセスを実行しました。
現在、CDVPlugin を使用してネイティブ iOS と Phonegap をハイブリッド化しようとしています。homescreen.html に画像 (カメラ アイコン) があるため、画像をクリックすると、画像タグ onclick() が起動し、PBJViewController.m ファイルの -(void) _setup() メソッドが呼び出されます。そのため、mainscreen.html は、いくつかのカスタム デザインでカメラ オプションを表示および非表示にしました。
そこで、PBJViewController.h と PBJViewController.m、PBJStrobeView.h と PBJStrobeView.m、PBJVisionUtilities.h と PBJVisionUtilities.m、最後の PBJVision.h と PBJVison.m のファイルを plugins フォルダーに配置しました。
次に、PBJViewController.js という名前の JavaScript ファイルを作成し、www フォルダーに追加します。
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();
});
そして、homescreen.html ファイルの関数 video() に呼び出しコードを書きました。
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");
}
そして、PBJViewController.h ファイルにいくつかの変更を加えました
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
そしてPBJViewcontroller.mファイルで
#import "PBJViewController.h"
#import "PBJVision.h"
#import "PBJStrobeView.h"
#import <Cordova/CDVPlugin.h>
#import <AssetsLibrary/AssetsLibrary.h>
#import <MediaPlayer/MediaPlayer.h>

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

ここで、UIViewController "@interface PBJViewController : CDVPlugin" の CDVPlugin を置き換えるため、「CDVPlugin」が「viewWillAppear:」に応答しない可能性があるという警告メッセージが表示されます。
そして、プラグインの名前と値をconfig.xmlファイルに含めます。

これらは私のサンプルコードの1つです。私の問題は、目的の出力が得られないことです。
ヒントや結果を教えてください。
