Question

到目前为止，我的相机工作正常，它以常规格式打开。但我希望唯一的选择是方格式。

到目前为止，这是我的代码。

@IBAction func takePhoto(sender: AnyObject) {
    let picker = UIImagePickerController()

    picker.delegate = self
    picker.sourceType = .Camera

    presentViewController(picker, animated: true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    imageView.image = info[UIImagePickerControllerOriginalImage] as? UIImage
    dismissViewControllerAnimated(true, completion: nil)
}

Answer 1

我认为您不能使用UIImagePickerController以方格格式打开相机。你可以做的是将UIImagePickerController allowEditing设置为YES，然后从结果dict中使用键UIImagePickerControllerEditedImage然后你将得到平方图像，这样你就可以编码了。

@IBAction func takePhoto(sender: AnyObject) {
    let picker = UIImagePickerController()

    picker.delegate = self
    picker.sourceType = .Camera
    picker.allowsEditing = true

    presentViewController(picker, animated: true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    imageView.image = info[UIImagePickerControllerEditedImage] as? UIImage
    dismissViewControllerAnimated(true, completion: nil)
}

此answer中提到了另一种方法。您可以使用answer中的逻辑来编写swift中的代码。
