美好的一天,我正在学习
Swift,需要一些帮助.
用户正在注册并选择他们的图像.在解雇图像选择器后,我想让ComposeViewController出现.
这是代码：
func imagePickerController(picker: UIImagePickerController,didFinishPickingMediaWithInfo info: NSDictionary!) {
let pickedImage:UIImage = info.objectForKey(UIImagePickerControllerOriginalImage) as UIImage
//Scale Down Image
let scaledImage = self.scaleImageWith(pickedImage,and: CGSizeMake(100,100))
let imageData = UIImagePNGRepresentation(scaledImage)
let imageFile:PFFile = PFFile(data: imageData)
PFUser.currentUser().setObject(imageFile,forKey: "profileImage")
PFUser.currentUser().saveInBackgroundWithTarget(nil,selector: nil)
picker.dismissViewControllerAnimated(true,completion: nil)
//this is the line seems to have problem.
self.navigationController?.popToViewController(ComposeViewController,animated: true)
}
然后我收到了这些错误：
ComposeViewController.Type’不能转换为’UIViewController
类型名称后的预期成员名称或构造函数调用
它有建议通过在ComposeViewController之后put()来修复,但是在修复之后它会发出更多错误.
希望有人能提供帮助.谢谢！
