Render .h Blender Export to iPhone with openGL ES 1.1

Question

I have a blender image exported using Jeff LaMarche .h export script. I am trying to get it to render in OpenGL ES 1.1. I don't think I am passing my vertices, normals, and texture coords right. Can someone help me out. Here is what I have.

This is the .h file with my vertices,etc.

struct vertexDataTextured
{
    GLKVector3      vertex;
    GLKVector3      normal;
    GLKVector2      texCoord;
};
typedef struct vertexDataTextured vertexDataTextured;
typedef vertexDataTextured* vertexDataTexturedPtr;


static const vertexDataTextured MeshVertexData[] = {
    {/*v:*/{0.351562, 0.828125, -0.242188}, /*n:*/{0.183599, 0.982971, 0.005310}, /*t:*/{0.199397, 0.671493}},
    {/*v:*/{0.445312, 0.781250, -0.156250}, /*n:*/{0.715171, 0.222724, 0.662465}, /*t:*/{0.216226, 0.665719}},
    {/*v:*/{0.476562, 0.773438, -0.242188}, /*n:*/{0.964446, 0.263863, 0.012665}, /*t:*/{0.216737, 0.679097}},
    {/*v:*/{-0.476562, 0.773438, -0.242188}, /*n:*/{-0.964446, 0.263863, 0.012665}, /*t:*/{0.052251, 0.677297}},
    {/*v:*/{-0.445312, 0.781250, -0.156250}, /*n:*/{-0.715171, 0.222724, 0.662465}, /*t:*/{0.053356, 0.663955}},

...

and here is my drawing code

...

glClearColor(1.0f, 1.0f, 0.0f, 1.0f); 
glClear(GL_COLOR_BUFFER_BIT); 


glMatrixMode(GL_MODELVIEW); 
glLoadIdentity(); 
glTranslatef(0.0f,-0.3f,-0.5f);


glVertexPointer(3, GL_FLOAT, 0, MeshVertexData); 
glEnableClientState(GL_VERTEX_ARRAY); 


glNormalPointer(GL_FLOAT, 0 , MeshVertexData);
glEnableClientState(GL_NORMAL_ARRAY);


glEnable(GL_TEXTURE_2D);                                             
glEnable(GL_BLEND);                                                  

glTexCoordPointer(2, GL_FLOAT,0,MeshVertexData);                      
glEnableClientState(GL_TEXTURE_COORD_ARRAY);                        

glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_NEAREST); 
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); 

//glTranslatef(0.0f,-1.0f,-1.5f); 

glDrawArrays(GL_TRIANGLES, 0, sizeof(MeshVertexData)/ sizeof(vertexDataTextured));                               



glDisableClientState(GL_VERTEX_ARRAY); 
glDisableClientState(GL_NORMAL_ARRAY);
glDisableClientState(GL_TEXTURE_COORD_ARRAY);

Basically it looks like my screen threw up triangles everywhere. Any help for this N00B is very appreciated. Thanks

You're setting your stride to 0. It should be sizeof (vertexDataTextured). It tells OpenGL how many bytes there are between one vertex (or normal, or texture coord) and the next.
