1)BASIC UVMAPPING

Let's start with an easy one.UV mapping Primitives like spheres,boxes,cylinders,planes etc.
Before starting uvmapping make sure you have the texture loaded and the material assigned to the object(mesh).
Now go to the Modifiers tab dialog.Select UVmapping and press the Modify button.

If it's a sphere then do a spherical uv mapping.Of course this still depends on what you have in mind but for now let's do the basics.Your choices are: Box,Cylindrical,Spherical,Planar.X Y Z radio buttons are used for defining the facing or orientation axis.To understand this better see the images below.
 
 
 
 
 
 
 
 
 
 
 
 
 
 

I use planar mapping so that the gizmo(yellow rect) shows the orientation:

The Fit button  is used in cases where the XYZ sizes of the object are not the same and you need to wrap the object.
Normally the > axis size is used for all gizmo's XYZ axes sizes.

U,V values are used for scaling.i.e.: if you wanted the texture tiled 2 times you should set value 2.
Flip check boxes are self-explanatory.

Continuing with the sphere:
Press the Apply button and the object is uvmapped.If not satisfied Undo and try again.When finished press the Modify button to get out of the UVmapping modifier mode.NOTE: If the texture is upside-down check the Flip V button to flip vertical.

2)THE GIZMO GRAPH

The Gizmo graph is a helper object used by most Modifiers to help preview the modification or show the orientation,scaling,position.When the color is ORANGE the gizmo can not be Positioned,Rotated,Scaled and it will always follow the object(s).When it is YELLOW you can PRS(pos,rot,scale) it as a regular object.In the uvmapping case you can change the scaling for instance instead of setting U,V values for tiling.If you do alter its pos,rot,scale after applying it will be reset.
