Question

使用两个UIImageview和两个按钮，当点击第一个按钮图像选择器让你选择图像

从照片库和第二个按钮。这就是我做的事情

viewcontroler.h

UIImagePickerController *pic1;
UIImagePickerController *pic2;
UIImage *image1;
UIImage *image2;

IBOutlet UIImageView *imageview1;
IBOutlet UIImageView *imageview2;

-(IBAction)Load1:(id)sender;
-(IBAction)Load2:(id)sender;

vewcontroller.m

  -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

   image1 = [info objectForKey:UIImagePickerControllerOriginalImage];
   image2 = [info objectForKey:UIImagePickerControllerOriginalImage];
   [imageview1 setImage:image1];
   [imageview2 setImage:image2];


   [self dismissViewControllerAnimated:YES completion:NULL];

}


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


- (IBAction)Load1:(id)sender
{
   pic1 = [[UIImagePickerController alloc]init];
   pic1.delegate = self;
   [pic1 setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
   [self presentViewController:pic1 animated:YES completion:NULL];
}

- (IBAction)Load2:(id)sender
{
   pic2 = [[UIImagePickerController alloc]init];
   pic2.delegate = self;
   [pic2 setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
   [self presentViewController:pic2 animated:YES completion:NULL];


}

我跑的时候。第一个按钮工作。让你从照片库中选择图像并显示它，第二个按钮按原样工作，但您选择的图像在UIImageview

中显示我在这里做错了什么，谢谢

这些行导致两个图像视图具有您选择的相同图像：

image1 = [info objectForKey:UIImagePickerControllerOriginalImage];
image2 = [info objectForKey:UIImagePickerControllerOriginalImage];

两个图像视图都具有与：UIImagePickerControllerOriginalImage相同的源图像：

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

您需要做的是区分按下哪个按钮以及应该包含该图像的imageview。当然可以遵循许多方法：就像你可以使用一些bool来区分调用者：

 -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
   if (button1Clicked)   //Boolean to determine which button was pressed, set it in IBAction of the button
   {
      image1 = [info objectForKey:UIImagePickerControllerOriginalImage];
      [imageview1 setImage:image1];
   }
   else
   {
      image2 = [info objectForKey:UIImagePickerControllerOriginalImage];
      [imageview2 setImage:image2];
   }

      [self dismissViewControllerAnimated:YES completion:NULL];

}

或任何其他相关方法。
