これには明らかな答えがあると確信していますが、間違った検索基準を使用しているだけです。他にどこに聞いたらいいのかわからない！
I have an app that runs as an iPhone app and a Mac desktop app. All over the web when someone wants to showcase an app they have images of the app screenshot in showing on the screen of an iPhone. This iPhone almost always has a light shadow going over the top right of the screen. For example http://www.sparrowmailapp.com/iphone.php. This is just an edit of any number of stock iPhone images that can be found by Googling, for example http://images.apple.com/iphone/design/images/hero_front.jpg. However, it has this consistent shadow. This tells me that somewhere there's a PSD that has the iPhone casing, with a blank area in the middle to copy your screenshot into, and the light shadow that stays as the top layer.
しかし、どこでこれを見つけることができますか? Apple サイトに何らかのジェネレーターがありますか? 誰かが公式アセットのセットをどこかに公開しましたか? iPhone 5版とMacBook版の両方を探しています。
ありがとう
