如何从 fbprofilepictureview 检索图像并将此图像存储到数据库中

Question

显示个人资料图片。

      self.userProfileImage.profileID = user.id;

但是

       for (NSObject *obj in [userProfileImage subviews]) {
        if ([obj isMemberOfClass:[UIImageView class]]) {
            UIImageView *objImg = (UIImageView *)obj;
            img_ProfilePictureImg.image = objImg.image;
            break;
        }
    }
    img_ProfilePictureImg.image=[UIImage imageWithContentsOfFile:profileImage];

我没有得到 ---fbprofilepicture

     UIImage *img_Profile = --------.imageView.image; // How to get that image view 
     NSData *dataOfProfilePic = UIImagePNGRepresentation(img_Profile);

Answer 1

https://graph.facebook.com/username/picture?redirect=true

使用此网址，您可以获得个人资料图片。

在 Facebook Delegate loginViewFetchedUserInfo 中，您可以获得用户个人资料图片的图片 url

 - (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                            user:(id<FBGraphUser>)user 
{

NSString *imageUrl=[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?redirect=true", user.username];

}
