iOS :如何获取Facebook相册照片的选择器

Question

Facebook iOS SDK 是否提供任何默认 (Facebook) 相册照片的选择器，就像 UIImagePickerController 一样？

我听说过这个，所以搜索了很长时间，但找不到任何东西。

如果有人对此有任何想法，请告诉我。如果不是，那我肯定需要自己做。

Answer 1

Facebook iOS SDK 目前不提供此类功能。相反，我找到了第三方 class 做完全相同的事情。 https://github.com/OceanLabs/FacebookImagePicker-iOS/

Answer 2

从 Facebook 导入

没有第三方工具从相册Working For graph api 2.4, 2.5, 2.6,2.7,2.8 & Facebook graph api 2.10

1) 在 Facebook 开发者帐户中添加应用程序

2) 然后在应用程序中选择平台以便更好地理解，请参见以下屏幕截图

3) 选择 ios 并按照向导中的所有步骤显示进行操作

4) 然后转到图表 api 探索 https://developers.facebook.com/tools/explorer/145634995501895/

5)select 你在图表中的应用 api explorer 更多了解显示屏幕截图

6) 点击 Get token ..然后在 get token 中点击 get access token 你可以看到这么多权限以便更好地理解看图片

7) 打开或关闭检查您的权限以在屏幕截图后显示相册名称和图像

如果 user_photos 权限未打开则显示错误，请参见以下屏幕截图

完成第 7 步后，请执行以下步骤或仅下载编码文件。我已经把 link 放在哪里你可以下载

objective c

的编码文件

8) 如果没有错误显示，那么在 viewDidLoad 方法中的以下代码在视图 controller.this 代码中用于获取相册名称和相册 ID。

objective C

     FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];

    [loginManager logInWithReadPermissions:@[@"public_profile", @"email", @"user_friends",@"user_photos"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)

    {

        [[[FBSDKGraphRequest alloc]
          initWithGraphPath:@"me/albums"
          parameters: nil
          HTTPMethod:@"GET"]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
             if (!error) {

               //  NSLog("%@",result);

                 NSArray *data = [result valueForKey:@"data"];


                 name = [data valueForKey:@"name"];

                 ids = [data valueForKey:@"id"];


                 [self.Fbtableview reloadData];


             }


         }];

9) 现在在 tableview 单元格行 中输入代码后获取相册封面照片

objective C

 coverid = [NSString stringWithFormat:@"/%@?fields=picture",[ids objectAtIndex:indexPath.row]]; **// pass album ids one by one**


/* make the API call */
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                              initWithGraphPath:coverid
                              parameters:nil
                              HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                      id result,
                                      NSError *error)
 {

    // NSLog("%@",result);

     NSDictionary *pictureData  = [result valueForKey:@"picture"];

     NSDictionary *redata = [pictureData valueForKey:@"data"];

     urlCover = [redata valueForKey:@"url"];



     NSURL *strUrl = [NSURL URLWithString:[NSString stringWithFormat:@"%@",urlCover]];

     NSData *data = [NSData dataWithContentsOfURL:strUrl];
     UIImage *img = [[UIImage alloc] initWithData:data];
     UIImageView *img1;

     if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
     {
         img1= [[UIImageView alloc]initWithFrame:CGRectMake(10, 0, 50, 50)];
     }
     else
     {
         img1= [[UIImageView alloc]initWithFrame:CGRectMake(10, 0, 40, 40)];
     }



     [img1 setImage:img];
     [img1 setContentMode:UIViewContentModeScaleAspectFit];
     [cell.contentView addSubview:img1];


 }];

10)现在是获取相册照片 ID 的代码。

 // code in **table didselect method**

objective C

   NSString *strAlbumid = [NSString stringWithFormat:@"/%@/photos",[ids objectAtIndex:indexPath.row]];



FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                              initWithGraphPath:strAlbumid
                              parameters:nil
                              HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                      id result,
                                      NSError *error) {

    // NSLog("%@",result);
    NSDictionary *data = [result valueForKey:@"data"];

    arrId = [data valueForKey:@"id"];



    PhotoViewControllerr *photoViewcontroller;

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        photoViewcontroller = [[PhotoViewControllerr alloc]initWithNibName:@"PhotoViewController_Ipad" bundle:nil];
    }
    else
    {
        photoViewcontroller = [[PhotoViewControllerr alloc]initWithNibName:@"PhotoViewController" bundle:nil];
    }


    photoViewcontroller.picsArray = arrId;

    [photoViewcontroller.navigationController setNavigationBarHidden:YES];




    [[self navigationController] pushViewController:  photoViewcontroller animated:YES];


}];

11) 另一个视图控制器现在用于在 collection view cellforRow

中获取图像的代码

objective C

NSString *strAlbumid = [NSString stringWithFormat:@"/%@/?fields=images",[self.picsArray objectAtIndex:indexPath.row]];



FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                              initWithGraphPath:strAlbumid
                              parameters:nil
                              HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                      id result,
                                      NSError *error)
{

    //NSLog("%@",result);
    picture_images = [result valueForKey:@"images"];

    NSMutableArray *picCount = [picture_images objectAtIndex:picture_images.count - 1];



     NSURL *strUrl = [NSURL URLWithString:[NSString stringWithFormat:@"%@",[picCount valueForKey:@"source"]]];


    dispatch_queue_t q = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);
    dispatch_async(q, ^{
        /* Fetch the image from the server... */
       NSData *data = [NSData dataWithContentsOfURL:strUrl];
         UIImage *img = [[UIImage alloc] initWithData:data];
         dispatch_async(dispatch_get_main_queue(), ^{

         if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
         {

         img1= [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 200, 200)];
         }
         else
         {

         img1= [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
         }



         img1.image = img;
         img1.contentMode = UIViewContentModeScaleAspectFit;
         [cell.contentView addSubview:img1];

         });
         });



}];
