【问题描述】：
我有一个在容器视图中以编程方式创建的图像视图：
Screen shot with circular profile image view inside container view
我在配置文件图像视图顶部有一个按钮覆盖来调用图像选择器控制器。当从照片库中选择图片时，图片会占据整个屏幕，如下所示：
Screenshot after image is selected
这里是这个视图控制器的 viewDidLoad() 和 imagePickerController() 的代码：
override func viewDidLoad() {
super.viewDidLoad()
self.profileBackgroundView.backgroundColor = UIColor.init(red: CGFloat(69.0/255.0), green: CGFloat(171.0/255.0), blue: CGFloat(222.0/255.0), alpha: CGFloat(1))
//initializePrimaryUserData()
fullNameTextField.text = self.primaryUser.firstName + self.primaryUser.lastName
nickNameTextField.text = self.primaryUser.userName
//create profile image view
if hasProfilePic {
profileImage.image = self.primaryUser.image
} else {
image = UIImage(named: imageName)!
profileImage.image = image
}
profileImage.frame = CGRect(x: profileBackgroundView.bounds.midX, y: profileBackgroundView.bounds.midY, width: 100, height: 100)
profileImage.translatesAutoresizingMaskIntoConstraints = false
profileBackgroundView.addSubview(profileImage)
profileImage.centerXAnchor.constraint(equalTo: profileBackgroundView.centerXAnchor).isActive = true
profileImage.centerYAnchor.constraint(equalTo: profileBackgroundView.centerYAnchor).isActive = true
profileImage.layer.cornerRadius = profileImage.frame.size.width / 2
profileImage.layer.masksToBounds = false
profileImage.clipsToBounds = true
profileImage.contentMode = .scaleAspectFit
//create profileImageButton
let profileImageButton = UIButton(frame: CGRect(x: profileBackgroundView.bounds.midX, y: profileBackgroundView.bounds.midY, width: 100, height: 100))
profileImageButton.setTitle("Photo", for: .normal)
profileImageButton.addTarget(self, action: #selector(profileImageButtonClicked), for: .touchUpInside)
profileImageButton.translatesAutoresizingMaskIntoConstraints = false
profileBackgroundView.addSubview(profileImageButton)
profileImageButton.centerXAnchor.constraint(equalTo: profileBackgroundView.centerXAnchor).isActive = true
profileImageButton.centerYAnchor.constraint(equalTo: profileBackgroundView.centerYAnchor).isActive = true
// Do any additional setup after loading the view.
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
self.primaryUser.image = image
self.hasProfilePic = true
self.profileImage.image = image
self.profileImage.contentMode = .scaleAspectFit
self.profileImage.clipsToBounds = true
}
self.dismiss(animated: true, completion: nil)
}
