[__NsPlaceHolderArray initWithObjects: Graf:]: Versuch, kein Objekt aus Objekten einzufügen [0] ⇐ IOS

[Anonymous]

Ich habe Eagglview Hodling PresentFrameBuffer und das Speichern des Screenshots von Eagglview Senden Sie diesen Sreenshot an UiviewController für uiactivityViewController Social Network Framework. Also habe ich in NsuserDefaults gespeichert und dann in UIViewController abgerufen. Aber ich bekomme die App aufgrund der ungekordeneten Ausnahme 'nsinvalidargumentException', Reason: '*** -[__ nsplepeholderArray initWithObjects: Graf:]: Versuch, kein Objekt aus Objekten einzufügen [0]' < /code> < /p>

UIImageWriteToSavedPhotosAlbum(self.screensht, nil, nil, nil);
