[iOS][Objective-c]图像选择器到下一个控制器

我想将图像发送到下一个控制器，但出现错误

由于未捕获异常而终止应用程序 “NSInvalidArgumentException”，原因：'-[UINavigationController imgMediaSelect]：发送到实例0x15979a00'的无法识别的选择器

我将uiimagepickercontroller方法移动到下一个控制器

您的

完成了使用信息的PickingMediaWithInfo

方法应该如下所示。在执行任何操作之前，您将放弃您的观点

- (IBAction)sendPhoto:(id)sender {
    [DinsowMiniLogger log:@"Image: %@", self.pickedImage];
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentViewController:picker animated:YES completion:nil];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:YES completion:nil];
    [[self navigationController] dismissViewControllerAnimated:YES completion:nil];
    self.selMediaItem = [self.storyboard instantiateViewControllerWithIdentifier:@"selectmedia"];
    [self presentModalViewController:self.selMediaItem animated:YES];
    self.selMediaItem.imgMediaSelect.image = [info objectForKey:UIImagePickerControllerOriginalImage];
}

请显示定义imgMediaSelect的位置好吗？只需在下一个视图控制器中定义UIImage的属性，然后将图像分配给self.selMediaItem.imageProperty=[info objectForKey:UIImagePickerControllerOriginalImage]；然后在下一个viewcontroller中显示图像。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *browsed_Image =  [info objectForKey:UIImagePickerControllerOriginalImage];
   [picker dismissViewControllerAnimated:YES completion:^{
       if (browsed_Image) {
           // You can store here your image in UIImage object or directly pass it to next controller.
           [btn_UserImage setImage:browsed_Image forState:UIControlStateNormal];
        }
    }];
}
