Facebook iOS SDK 是否像 UIImagePickerController
那样提供任何默认的 (Facebook) 相册照片选择器?
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,那么我肯定需要自己制作。
最佳答案
从 Facebook 导入
无需第三方工具即可从 Working For graph api 2.4、2.5、2.6、2.7、2.8 和 Facebook graph api 2.10 相册中获取 facebook 照片
1) 在Facebook开发者账户中添加应用
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
4) 然后去graph api explore https://developers.facebook.com/tools/explorer/145634995501895/
5) 在 graph api explorer 中选择您的应用程序以获得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) 用于检查您的权限以获取相册名称和图像在屏幕截图后显示
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。我已经把链接放在那里你可以下载
objective-c 的编码文件

8) 如果没有错误显示,则在 View Controller 的 viewDidLoad 方法中执行以下代码。此代码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 cell for row
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 View Controller 现在代码用于在 collection view cellforRow
中获取图像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];
});
});
}];
12) 获取数据后,您必须在 facebook 中提交您的应用程序,以便提交您可以填写信息
1)应用详情
2)现状与回顾
