openGLES ES1 problem

 void MySprite :: draw () {
glLineWidth (5); 
glColor4f (1.0, 0.0, 0.0, 1.0); 
glDisable (GL_TEXTURE_2D); 
glDisableClientState (GL_TEXTURE_COORD_ARRAY); 
glDisableClientState (GL_COLOR_ARRAY); 

GLfloat ver [4] = {100,50,200,50}; 
/ / GlVertexAttribPointer (0, 2, GL_FLOAT, GL_FALSE, 0, ver); 
glVertexPointer (2, GL_FLOAT, 0, ver); 
glDrawArrays (GL_LINES, 0, 3); 

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

I xcode eyed opengles es1
Why do I use glVertexPointer () This method does not qualify for a draw. But I glVertexAttribPointer can draw to qualify, but the line color is gray instead of red, how else to you. Expert help

Unlike you OpenGLES of this code, but rather the OpenGL

Talk OpenGL ES1 and OpenGL ES2 use there is a difference:
/ / OpenGL ES 1.1 wrote:
glVertexPointer (2, GL_FLOAT, ...);
glColorPointer (4, GL_FLOAT, ...);

/ / OpenGL ES 2.0 become so
glVertexAttribPointer (positionSlot, 2, GL_FLOAT, ...);
glVertexAttribPointer (colorSlot, 4, GL_FLOAT, ...);

Do not confuse the two friends
