Hi all, I'm new to this language objective - C and Xcode programmer. I have to make an app which allows users to capture image, record video, audio, then allow users to edit those audio, video file to make a clip. I have a working video record code, and audio record code. The problem I'm having now is to make multiview. Like main view is the menu, then the subview is for editing. I tried to make a simple switch view program, but all it shows is a white screen on simulator with no toolbar or button or anything... I follow exactly as a few guides on net. Could anyone tell me what did I do wrong? Also, I have one more question, the subview, where I intend to make 2 columns, 1 with a list of videos and images captured, the other one is a list of audio recorded files. users are allowed to move files in each column up and down to make an order of images and sound in the final clip. Could you guys suggest me what I should use to implement this? and what knowledge I need to have before starting to write the code for this subview? I'm really confused now and time is counting down, I really appreciated any help... Thanks you guys in advance.
