Ios6 手动触摸是否在rend ios中移动对象模型？

我从网站下载了这个项目

我运行此项目使茶壶旋转360度全旋转，但不停止旋转，触摸不旋转茶壶，因此我为停止旋转而工作，它工作正常，旋转停止后触摸移动茶壶，我将尝试以下代码：

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event;
{  
    CGPoint currentMovementPosition = [[touches anyObject] locationInView:glView_];

    [self renderByRotatingAroundX:(lastMovementPosition.x - currentMovementPosition.x) 
rotatingAroundY: (lastMovementPosition.y - currentMovementPosition.y) scaling:1.0f translationInX:0.0f translationInY:0.0f];

        lastMovementPosition = currentMovementPosition;       
}

- (void)renderByRotatingAroundX:(float)xRotation rotatingAroundY:(float)yRotation scaling:(float)scaleF translationInX:(float)xTranslation translationInY:(float)yTranslation{  

     currentCalculatedMatrix = CATransform3DIdentity;

     currentCalculatedMatrix = CATransform3DTranslate(currentCalculatedMatrix, 0.0, -0.2, 0.0);

    currentCalculatedMatrix = CATransform3DScale(currentCalculatedMatrix, 4.5, 4.5 *     (320.0/480.0), 4.5);

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

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); 
    GLfloat currentModelViewMatrix[16]; 
    // Perform incremental rotation based on current angles in X and Y
    if ((xRotation != 0.0) || (yRotation != 0.0))
    {
       GLfloat totalRotation = sqrt(xRotation*xRotation + yRotation*yRotation);
       CATransform3D temporaryMatrix = CATransform3DRotate(currentCalculatedMatrix, totalRotation * M_PI / 180.0,
                                                              ((xRotation/totalRotation) * currentCalculatedMatrix.m12 + (yRotation/totalRotation) * currentCalculatedMatrix.m11),
                                                            ((xRotation/totalRotation) * currentCalculatedMatrix.m22 + (yRotation/totalRotation) * currentCalculatedMatrix.m21),
                                                            ((xRotation/totalRotation) * currentCalculatedMatrix.m32 + (yRotation/totalRotation) * currentCalculatedMatrix.m31));
        if ((temporaryMatrix.m11 >= -100.0) && (temporaryMatrix.m11 <= 100.0))
            currentCalculatedMatrix = temporaryMatrix;
    }
    else
    {
    }   
    // Draw the teapot model    
    [self convert3DTransform:&currentCalculatedMatrix toMatrix:currentModelViewMatrix]; 

    [plainDisplayProgram use];    

    glUniformMatrix4fv(plainDisplayModelViewMatrix, 1, 0, currentModelViewMatrix);

    glVertexAttribPointer(plainDisplayPositionAttribute, 3, GL_FLOAT, 0, 0, cube_vertices);

    glEnableVertexAttribArray(plainDisplayPositionAttribute);

    NSLog(@"posit:%d,matrix=%d",plainDisplayPositionAttribute,plainDisplayModelViewMatrix);
    //Draw teapot. The new_teapot_indicies array is an RLE (run-length encoded) version of the teapot_indices array in teapot.h

    for(int i = 0; i < num_cube_indices; i += cube_indices[i] + 1)
    {
          NSLog(@"count:%d,i=%d",num_cube_indices,i);
      glDrawElements(GL_TRIANGLES, cube_indices[i], GL_UNSIGNED_SHORT, &cube_indices[i + 1]);
    }    

    [glView_ presentFramebuffer]; 
}

如果（（temporaryMatrix.m11>=-100.0）和（&（temporaryMatrix.m11我在这个rend ios项目中找到了答案，每次按按钮都会使用下面的代码移动对象模型：

-（无效）右按钮按下
{

}
它的工作很好。
使用移动的触控，它将在所有方向上清晰地旋转。试试这个

xangle和yangle在全球范围内声明并初始化为0.0
