Software Development tutorial --- 1. Camera call

1. Create a new project, and then create viewcontrollview. Here XIB can be used or not used. I am using the XIB file,

The image I used is a font file that can adapt to the Retina screen. It is a vector file. Next I will create a project, PS: the latest version of xcode6 I used.

Import the avfoundtion library after creation.

Go to the XIB file and drag a uiimageview control to fill the entire screen.

Enter the. h file to connect to the control.

Entered code

When running on a real machine, an image captured by the camera is displayed.
