PhoneGap 2.1 で iOS PhoneGap Screenshot プラグインを使用しようとしています。
これは私の Screenshot.m ファイルです (Plugind フォルダーに入れます)。

UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;

// landscape check
imageRect = CGRectMake(0, 0, CGRectGetHeight(screenRect), CGRectGetWidth(screenRect));
} else {
// portrait check
imageRect = CGRectMake(0, 0, CGRectGetWidth(screenRect), CGRectGetHeight(screenRect));
}
UIGraphicsBeginImageContext(imageRect.size);
CGContextRef ctx = UIGraphicsGetCurrentContext();
[[UIColor blackColor] set];
CGContextTranslateCTM(ctx, 0, 0);
CGContextFillRect(ctx, imageRect);
[webView.layer renderInContext:ctx];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
UIGraphicsEndImageContext();
UIAlertView *alert= [[UIAlertView alloc] initWithTitle:nil message:@"Image Saved" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}

これは私の Screenshot.h ファイルで、Plugins フォルダーに入れられます:

これは、www フォルダーに配置された私の Screenshot.js ファイルです。

(function() {
/* Get local ref to global PhoneGap/Cordova/cordova object for exec function.
- This increases the compatibility of the plugin. */
var cordovaRef = window.PhoneGap || window.Cordova || window.cordova; // old to new fallbacks
/**
* This class exposes the ability to take a Screenshot to JavaScript
*/
function Screenshot() { }
/**
* Save the screenshot to the user's Photo Library
*/
Screenshot.prototype.saveScreenshot = function() {
cordovaRef.exec(null, null, "Screenshot", "saveScreenshot", []);
};
cordovaRef.addConstructor(function() {
if (!window.plugins) {
window.plugins = {};
}
if (!window.plugins.Screenshot) {
window.plugins.Screenshot = new Screenshot();
}
});
})(); /* End of Temporary Scope. */
私は自分の関数を次の行で script.js と呼んでいます: window.plugins.Screenshot.saveScreenshot() ;
Cordova.plist に Screenshot プラグインを既に追加しました
今、私はアプリケーションを実行していますが、コンパイルエラーはありませんが、JS は機能せず、画像アプリにスクリーンショットがありません。
ご協力いただきありがとうございます
