如何實現通過手勢移動來調節呈現出來的畫面位置

實現步驟

• 1.單獨創建一個視圖放在最外層,放手勢對象

  [view addGestureRecognizer:self.panGesture];

• 2.創建一個滑動手勢

  self.pinchGesture = [[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(pinchGesture:)];

• 3.轉換為旋轉角度

  if (panGesture.state == UIGestureRecognizerStateBegan){CGPoint currentPoint = [panGesture locationInView:panGesture.view];self.lastPoint_x = currentPoint.x;self.lastPoint_y = currentPoint.y;[self.delegate gestureManager:self panGesture:panGesture matrix4:SCNMatrix4Identity]; }else{CGPoint currentPoint = [panGesture locationInView:panGesture.view];float distX = currentPoint.x - self.lastPoint_x;float distY = currentPoint.y - self.lastPoint_y;self.lastPoint_x = currentPoint.x;self.lastPoint_y = currentPoint.y;// 這里進行手勢滑動視角的微調,根據需求設置distX *= -0.005;distY *= -0.005;self.fingerRotationY += distX * OSVIEW_CORNER / 100.0;self.fingerRotationX += distY * OSVIEW_CORNER / 100.0;SCNMatrix4 modelMatrix = SCNMatrix4Identity;modelMatrix = SCNMatrix4Rotate(modelMatrix, self.fingerRotationX,1, 0, 0);modelMatrix = SCNMatrix4Rotate(modelMatrix, self.fingerRotationY, 0, 1, 0);

• 4.改變照相機的旋轉角度

  self.eyeNode.pivot = modelMatrix;
