Function

UIGraphicsGetCurrentContext

Returns the current graphics context.

Declaration

CGContextRef UIGraphicsGetCurrentContext(void);

Return Value

The current graphics context.

Discussion

The current graphics context is nil by default. Prior to calling its drawRect: method, view objects push a valid context onto the stack, making it current. If you are not using a UIView object to do your drawing, however, you must push a valid context onto the stack manually using the UIGraphicsPushContext function.

This function may be called from any thread of your app.
