Can't draw a filled rectangle in iPhone 5S and iPad Air

Question

This code draws a filled rectangle:

void ccDrawFilledRect( CGPoint v1, CGPoint v2 )
{
    CGPoint poli[]={v1,CGPointMake(v1.x,v2.y),v2,CGPointMake(v2.x,v1.y)};

    // Default GL states: GL_TEXTURE_2D, GL_VERTEX_ARRAY, GL_COLOR_ARRAY, GL_TEXTURE_COORD_ARRAY
    // Needed states: GL_VERTEX_ARRAY,
    // Unneeded states: GL_TEXTURE_2D, GL_TEXTURE_COORD_ARRAY, GL_COLOR_ARRAY
    glDisable(GL_TEXTURE_2D);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);
    glDisableClientState(GL_COLOR_ARRAY);

    glVertexPointer(2, GL_FLOAT, 0, poli);
    glDrawArrays(GL_TRIANGLE_FAN, 0, 4);

    // restore default state
    glEnableClientState(GL_COLOR_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);
    glEnable(GL_TEXTURE_2D);
}

It has always worked, until I begun using an iPhone 5S and iPad Air. I don't understand why doesn't it work with those devices - it was fine with all others. Always using the latest iOS version.

What might it be?

I doubt it matters, but I've been using cocos2d-iphone 1.0.1.

Fixed.

void ccDrawFilledRect( CGPoint v1, CGPoint v2 ) {

    float vertices[] = {
        v1.x,  v1.y,      // Bottom left
        v2.x,  v1.y,  // Bottom right
        v2.x,  v2.y, // Top right
        v1.x, v2.y // Top left
    };

    glDisable(GL_TEXTURE_2D);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);
    glDisableClientState(GL_COLOR_ARRAY);

    glVertexPointer(2, GL_FLOAT, 0, vertices);
    glDrawArrays(GL_TRIANGLE_FAN, 0, 4);

    glEnableClientState(GL_COLOR_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);
    glEnable(GL_TEXTURE_2D);
}

No, I have absolutely no idea why did the old code fail in the iPhone 5S and iPad Air, but this new code seems to work on all devices now.
