篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了使用UIImagePickerController“使用未知类型创建图像格式是一个错误”相关的知识,希望对你有一定的参考价值。
在ios 10 Swift 3中从图像选择器中选择图像时,我收到错误 - Creating an image format with an unknown type is an error
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
imagePost.image = image
self.dismiss(animated: true, completion: nil)
}
图像未被选中和更新。我需要帮助或建议才能知道在iOS10或Swift 3中是否更改了此方法的语法或任何内容,或者是否有其他方法可以执行此操作。
下面提到的代码确实解决了我的问题 -
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
imagePost.image = image
} else{
print("Something went wrong")
}
self.dismiss(animated: true, completion: nil)
}
这对我有用:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
imageView.image = image
self.dismiss(animated: true, completion: nil)
}
}
如果这对任何人都有帮助,那么当我将UIImageView子类化以创建圆角视图时,我就会发生这种情况。当我在viewDidLoad()中添加以下行时也发生了这种情况
imageView.layer.cornerRadius = self.imageView.frame.size.width / 2
我最终在viewWillLayoutSubViews中添加了这一行并且它有效。有关详细信息,请参阅此

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let image = info[UIImagePickerControllerOriginalImage] as? UIImage
self.dismiss(animated: true, completion: nil)
self.imageTook.image = image
}
将didFinishPickingMediaWithInfo info: [String : AnyObject]
改为didFinishPickingMediaWithInfo info: [String : Any]
对于带有swift 3的Xcode 8.1,在更改委托方法后如下所示
改变你的
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
imagePost.image = image
self.dismiss(animated: true, completion: nil)
}
功能
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
imagePost.image = info[UIImagePickerControllerOriginalImage] as? UIImage
picker.dismiss(animated: true, completion: nil)
}
我忘了添加UINavigationControllerDelegate和UIImagePickerControllerDelegate
class ViewController:UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate
你会在一开始就添加一个变量
是imagePicker = UIImagePickerController()
并设置委托并在viewdidload()中调用一个函数
imagePicker.delegate = self
viwImagePick()
然后解释该功能为
//ImagePicker
func viwImagePick(){
let alert = UIAlertController(title: nil, message: "Choose your source", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Camera", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
print("Camera selected")
self.openCamera()
//Code for Camera
//cameraf
})
alert.addAction(UIAlertAction(title: "Photo library", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
print("Photo selected")
self.openGallary()
//Code for Photo library
//photolibaryss
})
self.present(alert, animated: true, completion: nil)
}
func openCamera()
{
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
if UIDevice.current.userInterfaceIdiom == .phone
{
self.present(imagePicker, animated: true, completion: nil)
}
else
{
let popover = UIPopoverController(contentViewController: imagePicker)
popover.present(from: profileImgViw.frame, in: self.view, permittedArrowDirections: UIPopoverArrowDirection.any, animated: true)
}
}
func openGallary()
{
imagePicker.sourceType = UIImagePickerControllerSourceType.savedPhotosAlbum
if UIDevice.current.userInterfaceIdiom == .phone
{
self.present(imagePicker, animated: true, completion: nil)
}
else
{
let popover = UIPopoverController(contentViewController: imagePicker)
popover.present(from: profileImgViw.frame, in: self.view, permittedArrowDirections: UIPopoverArrowDirection.any, animated: true)
}
}
现在,图像将添加到库中的图像视图中
我认为你错过了photoImageView和图像之间的联系。
看看下面的截图:

祝好运!
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
imgViewPhoto.image = image
} else{
print("Something went wrong")
}
picker.dismiss(animated: true, completion: nil)
}
一定要包括UINavigationControllerDelegate
代表。这解决了我的问题。
试试下面
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print("image selected");
let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImag
self.dismiss(animated: true, completion: nil)
UIImg.image = selectedImage
}
记得向自己添加委托
let picker = UIImagePickerController()
picker.delegate = self // delegate added
这对我有用。只需复制并粘贴即可。
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
// The info dictionary contains multiple representations of the image, and this uses the original.
let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
// Set photoImageView to display the selected image.
photoImageView.image = selectedImage
// Dismiss the picker.
dismiss(animated: true, completion: nil)
}
我做的是,一旦我从didFinishPickingMediaWithInfo获得图像,我打电话给:
func prepareImageForSaving(image:UIImage) {
// create NSData from UIImage
guard let imageData = UIImageJPEGRepresentation(image, 1) else {
// handle failed conversion
print("jpg error")
return
}
self.saveImage(imageData: imageData as NSData)
}
