Нужна помощь по отправке изображений через Bump Api

Мне нужна помощь. Я хотел бы перенести изображения Jpg или PNG с одного iPhone на другой через Bump. Я столкнулся с успехом и неудачей, когда изображения вообще не отправлялись.

ниже приведен файл NSObject, который будет вызываться, когда пользователь выбирает изображения из UIimagepicker.

приемник не будет отправлять данные, а будет только получать.

Пожалуйста, помогите мне взглянуть на код и дать мне какие-либо комментарии или замечания.

благодарим и ценим вашу помощь.
