我们如何强制UII
ImagePickerController裁剪正方形图像？
我已经搜索过,我还没有找到一个坚实的解决方案.谢谢
var imagePickerController: UIImagePickerController = UIImagePickerController();
imagePickerController.allowsEditing = true;
imagePickerController.delegate = self;
imagePickerController.sourceType = sourceType;
func imagePickerController(picker: UIImagePickerController,didFinishPickingImage image: UIImage!,editingInfo: [NSObject : AnyObject]!) {
profilePictureSelected = true;
profilePictureImageView.image = image;
picker.dismissViewControllerAnimated(true,completion: nil);
}
解决方法
您正在正确地执行,直到您收到委托回调,在您需要指定它是您要使用的编辑图像的回调中.请注意,我在这里使用不同的委托方法.
func imagePickerController(picker: UIImagePickerController,didFinishPickingMediawithInfo info: [NSObject : AnyObject]) {
if let chosenImage = info[UIImagePickerControllerEditedImage] as? UIImage {
profilePictureSelected = true;
profilePictureImageView.image = chosenImage;
}
picker.dismissViewControllerAnimated(true,completion: nil);
}
