Question

我刚刚启动了facebook集成，并在我的应用程序中下载了用户的详细信息。现在问题是我得到除了配置文件pic之外的所有其他细节，当NSloged返回null时。我究竟做错了什么。我已经获得了基本信息的权限。请帮我。提前完成。

FBRequest * request = [FBRequest requestForMe];

// Send request to Facebook
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
    if (!error) {
        // result is a dictionary with the user's Facebook data
        NSDictionary *userData = (NSDictionary *)result;

        nickname.text= userData[@"name"];
        firstName.text=userData [@"first_name"];
        lastName.text=userData[@"last_name"];
        city.text=userData[@"user_location"];
        gender.text= userData[@"gender"];
        dateOfBirth.text = userData[@"birthday"];


        NSURL *pictureURL = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large", userData[@"id"]]];

        NSData *data =[NSData dataWithContentsOfURL:pictureURL];
        NSLog(@" profile pic data = %@", data);
        self.imageToUpload.image=[UIImage imageWithData:data];
        NSString *imgstr=[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
        NSLog(@"%@",imgstr);

        [PFUser logOut];

        // Now add the data to the UI elements
        // ...
    }
}];

你永远不能下载用户形象facebook不允许它我不久前发送了几周但是没有以任何方式工作。

但根据我的经验，您不需要图像@所有只需url就能在您需要帮助的地方工作，如果您需要有关如何显示图像的帮助我可以帮助您

检查步骤（6）

并下载项目，在项目中拖动库SDWebImage文件夹

#import "SDWebImage/UIImageView+WebCache.h"


    [userImage setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large",[user objectForKey:@"id"]]]
                  placeholderImage:[UIImage imageNamed:@"unknownUser.png"]]

;

Answer 2

通过请求此网址

获取登录用户的ID

https://graph.facebook.com/me

然后您可以通过创建这样的网址来请求个人资料照片：

https://graph.facebook.com/<userid>/picture

我希望这会有所帮助。
