你有从Camera Roll到新的视图控制器的任何方法吗？

Question

我正试图从Camera Roll转到新的视图控制器。所以基本上我想能够选择一张图片，选择图片后，它会显示在新视图控制器上的imageView上？那很难吗？

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:
(NSDictionary *)info{
self.chosenImage = info[UIImagePickerControllerOriginalImage];
 [self.imageView setImage:self.chosenImage];
[self dismissViewControllerAnimated:YES completion:nil];
}

-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissViewControllerAnimated:YES completion:nil];
}

Answer 1

在您的图像选择器委托方法中，每当您拍摄图像时，它都会采用以下方法

-(void)imagePickerController:(UIImagePickerController *)picker
  didFinishPickingImage : (UIImage *)image
             editingInfo:(NSDictionary *)editingInfo
{
 //store image here as NSData or as you like 
 // go to the view controller when you want to use image and use the image data
  // do all the stuf you need in this method
}
