    Hiii guys,

    Today I'll be demonstrating how to pick any image via Gallery or via Camera in iOS ObjecticeC

    1. Create a ViewController & add these two delegates to it-UIImagePickerControllerDelegate and UINavigationControllerDelegate.

    2. Now add two buttons one for accessing Camera & another for Gallery.

    3. Make their actions as- - (IBAction)takePhoto:(id)sender; - (IBAction)selectPhoto:(id)sender;

    4. Add the following code to the action of both the buttons as-

    
                //Takephoto via camera//
    
    - (IBAction)takePhoto:(id)sender {    
    
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];     picker.delegate = self;     picker.allowsEditing = YES;picker.sourceType = UIImagePickerControllerSourceTypeCamera;    
    
    [self presentViewController:picker animated:YES completion:NULL];
    
    }            
    
          //SelectPhoto via gallery//
    
    - (IBAction)selectPhoto:(id)sender {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];    
    
    picker.delegate = self;
    
    picker.allowsEditing = YES;   
    
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    
     [self presentViewController:picker animated:YES completion:NULL];
    }


    5. Take another ViewController & add an ImageView to it & make an IBOutlet of this ImageView,name this ViewController as SecondView Controller.

    6. Add UIImagePickerControllerDelegate and UINavigationControllerDelegate delegates in secondView Controller

    7. Now create a push segue from Gallery button to the SecondView Controller

    8. After adding imagepicker delegate, add this function to seconView Controller

    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {    
    
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];   
    
      self.imgView.image = chosenImage;    
    
       [picker dismissViewControllerAnimated:YES completion:NULL];
    
    }

    Here imgView is the imageView that we have created. Thanks a lot for reading, I hope it helps.
