Step by step for starter developers… 1. Create a project in xCode with name “DragAndDrop” or any else…2. Add an element “NSImageView” on main view in the MainMenu.xib

Hi there! We are a group of iPhone / Android developers who have developed a suite of web services to assist us and other developers in building great apps.

Не работает touchesBegan и touchesEnded в UIScrollView Что делать? Много людей пишет об этой проблеме. Для себя я нашел не совсем стандартное решение. К примеру есть контроллер X в котором наш UIScrollView. в этом же контроллере создадим UIView, но не совсем стандартный, а подготовленный зараннее и передюющий все ивенты  в наш контроллер X и вставим [...]
