[iOS] [Objective-c]圖像選擇器傳遞給下一個控制器

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];
}

我想將圖像發送到下一個控制器但是出錯

由於未捕獲的異常“ NSInvalidArgumentException”而終止應用程序，原因：“-[UINavigationController imgMediaSelect]：無法識別的選擇器已發送到實例0x15979a00”

更新我將uiimagepickercontroller方法移動到下一個控制器

Answer 1

您的didFinishPickingMediaWithInfo方法應如下所示。 在執行任何操作之前，您將關閉視圖。

- (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];
        }
    }];
}
