Question

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

我听说过这么长时间搜索它但却找不到任何东西。

如果有人对此有任何想法，请告诉我。如果不是，那么我肯定需要自己制作。

Answer 1

从Facebook导入

没有第三方工具的

从专辑中获取Facebook照片工作图pi 2.4,2.5,2.6,2.7,2.8＆amp; Facebook图表api 2.10

1）在Facebook开发者帐户中添加应用

2）然后在app中选择平台以便更好地理解以下屏幕截图

3）选择ios＆amp;按照向导中的所有步骤显示

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

5）在图形api explorer中选择你的应用程序了解更多了解显示屏幕截图

6）点击获取令牌..然后点击获取令牌中的获取访问令牌，您可以看到很多权限，以便更好地了解图像

7）用于获取或关闭获取专辑名称的权限。图像显示在屏幕截图之后

如果未启用user_photos权限，则显示错误，请参阅以下屏幕截图

完成步骤7后，请执行以下步骤或只下载编码文件。我已经把链接放在哪里可以下载

为目标c编码文件

8）如果没有错误显示，则在视图controller的 viewDidLoad 方法中执行以下代码。此代码用于获取相册名称＆amp;专辑ID。

目标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）现在在行查看表格单元格

中获取代码类型后的专辑封面照片

目标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）现在用于获取相册照片的代码。

 // code in **table didselect method**

目标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获取集合视图中的图像的代码cellforRow

目标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];

         });
         });



}];

12）获取数据后，您必须在Facebook提交您的应用程序以提交您可以填写信息

1）应用详情

2）状态和审核

Facebook iOS SDK目前还没有提供此类功能。相反，我找到了一个完全相同的第三方课程。 https://github.com/OceanLabs/FacebookImagePicker-iOS/
