Hi,

Thanks for the demo, I used Xcode8 on my Mac to test the program, it worked well for view controller.swift in detecting faces and displayed the results in the iPhone simulator.

Now I would like to test CameraViewController.swift, not sure if I can run it under Xcode on Mac? I assume the program needs to access iPhone Camera to take a photo, wonder if the test can be done
on Mac or I need to put the code to iPhone to complete the test.

Thanks

在viewDidLoad中调用detect 方法。会使得personPic 并不是最后得到的宽高，真正的宽高应该是在视图加载完毕并调整约束显示出来之后的。应该把detect方法放在ViewDidAppear 里面。否则在iPhone 5c 4s 等设备中红框的位置会出现错误，亲测！

Test it on face-2 image, somehow the boxes were shifted in both x and y directions, see the image below.

你好，我从简书上点过来，看到你的文章有写到可以检测到微笑、闭眼等

能否发个资料研究一下？
