toon shading ios and android

You can fake it pretty good with an environment map shader and by creating a classic flipped normal outline (Create a copy of your object, "grow" each vertices out along its normal, flip all normals, and then texture it black)

This would work as an environment map shader:

 Shader "iPhone/Env_Diffuse_NoLight" { 

Properties { _Color ("Main Color", Color) = (1,1,1,1) _Emission ("Emmisive Color", Color) = (0,0,0,0) _Blend ("Blend", Range (0, 1)) = 0.5 _MainTex ("Base (RGB)", 2D) = "white" _EnvMap ("EnvMap", 2D) = "white" { TexGen SphereMap }

} SubShader { Material { //Diffuse [_MainTex] Emission [_Emission] Ambient [_MainTex] } Pass { Lighting On

           SetTexture [_EnvMap] { 
             constantColor (0.5, 0.5, 0.5, [_Blend])
             combine texture lerp (constant) constant
           }
           
         SetTexture [_MainTex] { 
             combine texture * previous DOUBLE
          } 
          
          SetTexture [_MainTex] { 
              constantColor[_Color]
              combine previous * constant
          }
   } 

}

 SubShader {
   Pass { 
         SetTexture [_MainTex] { 
             combine texture
          } 
          
          SetTexture [_MainTex] { 
              constantColor[_Color]
              combine previous * constant
          }
   } 

}

Fallback "Mobile/Unlit (Supports Lightmap)" }

For the environment map texture you will have to experiment a bit. But I usually create a few rings in different shades of grey in the center of the map.
