我有两种方式将图像分享到Facebook。
SDK Way(完美的工作):
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
NSMutableArray *uploadImages = [[NSMutableArray alloc] init];
for (UIImage *image in images) {
FBSDKSharePhoto *sharePhoto = [[FBSDKSharePhoto alloc] init];
sharePhoto.caption = title;
sharePhoto.image = image;
[uploadImages addObject:sharePhoto];
}
content.photos = [NSArray arrayWithArray:uploadImages];
[FBSDKShareAPI shareWithContent:content delegate:self];
和SLRequest方式(仅发送1张图片):
+ (void)uploadPhotoToFacebook:(NSMutableArray *)imagesData imageTitle:(NSString *)title account:(ACAccount*)account completionBlock:(shareSocialResponse)completion
{
SLRequest *facebookRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodPOST
URL:[NSURL URLWithString:@"https://graph.facebook.com/me/photos"]
parameters:@{@"message": title}];
for (NSData *imageData in imagesData) {
[facebookRequest addMultipartData:imageData
withName:@"source"
type:@"multipart/form-data"
filename:@"photo!"];
}
NSLog(@"facebookRequest %@",facebookRequest);
facebookRequest.account = account;
[facebookRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)
{
if (error) {
NSLog(@"%@",error.description);
} else {
NSDictionary *returnedData = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error];
NSLog(@"returnedData: %@", [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]);
if ([urlResponse statusCode] != 200) {
dispatch_async(dispatch_get_main_queue(), ^{
NSString *errorMessage = @"We could not process your request now";
if ([returnedData valueForKeyPath:@"error.message"] != nil) {
errorMessage = [returnedData valueForKeyPath:@"error.message"];
}
completion(NO, errorMessage);
});
} else {
completion(YES, @"Your clip was posted!");
}
}
}];
}
我相信如果在多部分中发送的每个数据都可以工作,但是没有。
任何人都知道该怎么做?感谢。

facebook文档中有一些文章可能会对您有所帮助。
https://developers.facebook.com/docs/graph-api/making-multiple-requests
因此,在您的情况下,您需要在请求中发送一个名为batch
的字段,并且每个文件必须附加一个唯一的名称,以便其他人不会重写。
batch
字段的内容将是一个json,您将在其中指定请求的端点,如下所示(缩小btw):
[
{
"method": "POST",
"relative_url": "me/photos",
"body": "message=labrys",
"attached_files": "file1"
},
{
"method": "POST",
"relative_url": "me/photos",
"body": "message=circle",
"attached_files": "file2"
}
]
我用postman尝试过,该请求的设置应如下所示:
很抱歉没有发布代码,我不熟悉目标C,但我希望你能理解这一点。
