I am a beginner, I need to know how I can put in a UIScrollView multiple pages. These pages should contain interactive elements such as buttons,video and also text and image
You need to set 2 properties on your UIScrollView in order to have a smooth paging scroll.
[scroller setPagingEnabled:YES];
[scroller setContentSize:CGSizeMake(width, height)];
/* width here would be your view's width times the amount of pages you want. */
