创建未知类型的图像格式是错误的（lldb）

Question

I'm developing an app and it has two image views. Each image view has its own button to select image from camera roll. When I click the button one it shows a camera roll and I select an image and it is displayed in the image view1 but when I click the second button to select image from camera roll and select image, it shows the image on the image view1 instead of imageview2. Does anyone know how to solve it???.This is my interface. I'm using Objective-c language.

here is the code :

- (IBAction)CNICFront:(id)sender { 
    picker = [[UIImagePickerController alloc]init]; 
    picker.delegate=self; 
    [picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]‌​;
    [self presentViewController:picker animated:YES completion:NULL]; 
} 

- (IBAction)CNICBack:(id)sender { 
    pic = [[UIImagePickerController alloc]init]; 
    pic.delegate=self; 
    pic setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]‌​; 
   [self presentViewController:pic animated:YES completion:NULL]; 
} 

Delegate methods are for image view 1 is this: -

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{ 
     image=[info objectForKey:@"UIImagePickerControllerOriginalImage"];
     [self.imageView1 setImage:image]; 
     [self dismissViewControllerAnimated:YES completion:NULL]; 
 }

 -(void)imagePickerControllerDidCancel:(UIImagePickerControll‌​er *)picker{ 
     [self dismissViewControllerAnimated:YES completion:NULL]; 
 }

updated Code: example

.h file:

@property (weak, nonatomic) IBOutlet UIImageView *img1;
@property (weak, nonatomic) IBOutlet UIImageView *img2;
- (IBAction)but1:(UIButton *)sender;
- (IBAction)but2:(UIButton *)sender;

.m File file

    #import "ViewController.h"

    @interface ViewController ()<UIImagePickerControllerDelegate,UINavigationControllerDelegate>{
        UIImagePickerController *picker;
        NSString *ImageViewC;
    }

    @end

    @implementation ViewController

    - (void)viewDidLoad {
        [super viewDidLoad];
   picker = [[UIImagePickerController alloc]init];
    picker.delegate=self;


    }


    - (void)didReceiveMemoryWarning {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }


    - (IBAction)but1:(UIButton *)sender {
        ImageViewC=@"1";

        [picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
        [self presentViewController:picker animated:YES completion:NULL];

    }

    - (IBAction)but2:(UIButton *)sender {
        ImageViewC=@"2";

        [picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
        [self presentViewController:picker animated:YES completion:NULL];

    }

    -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{

        UIImage * image=[info objectForKey:@"UIImagePickerControllerOriginalImage"];
        if ([ImageViewC isEqualToString:@"1"]) {
            [self.img1 setImage:image];
        }else{
            [self.img2 setImage:image];
        }
        [self dismissViewControllerAnimated:YES completion:NULL];
    }

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

    }
    @end
