CoronaLuaCreateDictionary()

NSDictionary* CoronaLuaCreateDictionary( lua_State *L, int index ). Creates and returns a NSDictionary corresponding to the table at index. This NSDictionary contains the Obj-C equivalent of Lua types. The following indicates how Lua values in the table are converted to Obj-C values:

• Lua boolean → NSNumber
• Lua number → NSNumber
• Lua string → NSString
• Lua table → NSDictionary

CoronaLuaPushImage()

int CoronaLuaPushImage( lua_State *L, UIImage *image ). Creates a display object using image and pushes it to the top of the stack. If successful, returns 1 indicating that the object was pushed onto the Lua stack; otherwise returns 0.

CoronaLuaPushValue()

int CoronaLuaPushValue( lua_State *L, id value ). Pushes a Lua value onto the top of the stack corresponding to the Obj-C object value. Returns 1 if a corresponding Lua value can be created; 0 otherwise. The following Obj-C values can be converted:

• NSNumber → Lua boolean or Lua number (if not BOOL, conversion is assumed to be double)
• NSString → Lua string
• NSArray → Lua table (1-based, sequential, numerical indices)
• NSDictionary → Lua table
