创建未知类型的图像格式是错误（lldb）

我正在开发一个应用程序，它有两个图像视图。每个图像视图都有自己的按钮来从相机胶卷中选择图像。当我点击一个按钮时，它会显示一个相机胶卷，我选择一个图像并显示在图像视图1中，但是当我单击第二个按钮从相机胶卷选择图像并选择图像时，它会在图像view1上显示图像的imageview2。有谁知道如何解决它???这是我的界面。我正在使用Objective-c语言。创建未知类型的图像格式是错误（lldb）

这里是代码：

- (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]; 
}

委托方法可用于图像视图1是这样的： -

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

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

假设u有2图像视图v1和v2 ......在第二回合按钮动作U设置定图像v1.image =您的图像更改为v2.image =您的图像。或（从我们的屏幕镜头）我认为你给予同样的行动2按钮相同，在这种情况下，你需要使用标签值你的Takeapic按钮 –

后您的代码很容易解决您的问题。 –

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

更新代码：例如

.h文件中：

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

.m文件文件

#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 { 
     [email protected]"1"; 

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

    } 

    - (IBAction)but2:(UIButton *)sender { 
     [email protected]"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

此代码在imageView2中显示图像。实际上是，如果我点击button1它应该在imageView1中显示图像，如果我点击button2它应该显示图像在ImageView 2 @Naveen库马尔 – Hamza

viewdidload Intilaze ImageViewC字符串像ImageViewC = [[NSString alloc]初始化];并请检查我更新的代码...以指定ImageViewC的值。 –

这是一样的，当我点击button1它在imageView2中显示图像，当点击button2并选择图像时，它在imageView2中显示图像 – Hamza
