推荐答案

其中 takePhoto 和 chooseFromLibrary 是我自己的

确保引用适当按钮的出口到这些方法。

Make sure to reference outlets of appropriate buttons to these methods.

   -(IBAction)takePhoto :(id)sender

{
        UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];

        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
        {
            [imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
        }

        // image picker needs a delegate,
        [imagePickerController setDelegate:self];

    // Place image picker on the screen
    [self presentModalViewController:imagePickerController animated:YES];
}



-(IBAction)chooseFromLibrary:(id)sender
{

    UIImagePickerController *imagePickerController= [[UIImagePickerController alloc] init]; 
    [imagePickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];

    // image picker needs a delegate so we can respond to its messages
    [imagePickerController setDelegate:self];

    // Place image picker on the screen
    [self presentModalViewController:imagePickerController animated:YES];

}

//delegate methode will be called after picking photo either from camera or library
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{   
    [self dismissModalViewControllerAnimated:YES]; 
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];

    [myImageView setImage:image];    // "myImageView" name of any UIImageView.
}
