问题 I use UIImagePickerController to take a photo by camera of iPhone. I want to show both "take a photo" and "choose a photo". My code imagePicker = UIImagePickerController() imagePicker.delegate = self imagePicker.sourceType = .camera //imagePicker.sourceType = .PhotoLibrary presentViewController(imagePicker, animated: true, completion: nil) I tried to use imagePicker.sourceType = .Camera and imagePicker.sourceType = .PhotoLibrary together to do this, but it doesn't work... Thank you 回答1:

Resizing UIimages pulled from the Camera also ROTATES the UIimage?

阅读更多关于 Resizing UIimages pulled from the Camera also ROTATES the UIimage?

I am getting UIimages from the camera and assigning them to UIImageViews to be displayed. When I do this the camera gives me a 1200 x 1600 pixel image which I then assign to a UIImageView in my Application. The image is displayed as expected in the image view under this condition. However, when I attempt to RESIZE the retrieved UIImage before assigning it to the UIImageView, the image is resizing as expected but there IS a problem in that somewhere (in the RESIZING code?) my UIImage is getting ROTATED... As a result, when I assign the resized UIImage to a UIImageView the image is rotated 90

问题 When i try to load camera from my code, camera preview is black. If I wait for 10-20 seconds it will show real camera preview.

问题 I have added a UIImagePickerController to a UIViewController . I have also assigned the UIImagePickerControllerDelegate to that UIViewController . When I execute the following line, myPicker.delegate = self; Xcode gifts me with the following message: warning: assigning to id from incompatible type 'RootViewController' Then I added the UINavigationControllerDelegate protocol to the same UIViewController and the error message vanished. So, do I have to add both protocols to the UIViewController

问题 I need to open the ImagePicker in my app using SwiftUI, how can I do that? I thought about using the UIImagePickerController, but I don't know how to do that in SwiftUI. 回答1: Here's a "rough around the edges" implementation.

My problem, i cant able to open imagePickerController from CustomCell.m, its shows below error. Please give some idea to fix my issue. 回答1: TableViewCell is a view, you can not present on views instead UIViewController can handle it. You should transfer the control from your cell to your controller that holds tableview and creates custom cell for it. Try like this: Custom Cell .h

Can I load a UIImage from a URL?

阅读更多关于 Can I load a UIImage from a URL?

I have a URL for an image (got it from UIImagePickerController) but I no longer have the image in memory (the URL was saved from a previous run of the app). Can I reload the UIImage from the URL again? I see that UIImage has a imageWithContentsOfFile: but I have a URL. Can I use NSData's dataWithContentsOfURL: to read the URL? EDIT1 based on @Daniel's answer I tried the following code but it doesn't work... NSLog(@"%s %@", __PRETTY_FUNCTION__, photoURL); if (photoURL) { NSURL* aURL = [NSURL URLWithString:photoURL]; NSData* data = [[NSData alloc] initWithContentsOfURL:aURL]; self.photoImage =
