ios - [iOS][Objective-c] 图像选择器到下一个 Controller

Question

- (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];
}

我想将图像发送到下一个 Controller 但出错

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UINavigationController imgMediaSelect]: unrecognized selector sent to instance 0x15979a00'

更新
我将 uiimagepickercontroller 方法移动到下一个 Controller

Answer 1

您的 didFinishPickingMediaWithInfo方法应该如下所示。在执行任何操作之前，您正在关闭您的 View 。

- (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];
        }
    }];
}
