[英]How to get Email param of facebook using SLRequest in iOS Social Framework
[英]how to get read permission before publishing permission for uploading video on Facebook using SLRequest?
我只是想将Facebook共享集成到我的应用程序中,我的应用程序的最终产品是一个视频,因此我想到的是与朋友上传和共享最终编辑,我正在将本机社交框架与ACAccount Framework结合使用,以使我的应用程序正常工作来自Facebook的似乎有些奇怪的逻辑,我需要在请求publish_stream许可之前先请求读取许可,并且它们不能紧随其后(在某处读取),我的问题是我应该在哪里以及如何在我的代码中实现此逻辑,这里我的代码
ACAccountStore* accountStore = [[ACAccountStore alloc] init];
NSDictionary *options = @{
ACFacebookAppIdKey: @"My app ID",
ACFacebookPermissionsKey: @[@"user_birthday"],
ACFacebookAudienceKey: ACFacebookAudienceOnlyMe
};
ACAccountType *facebookAccountType = [accountStore
accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
[accountStore requestAccessToAccountsWithType:facebookAccountType options:options completion:^(BOOL granted, NSError *error) {
if (granted) {
NSArray *accounts = [accountStore
accountsWithAccountType:facebookAccountType];
ACAccount * facebookAccount = [accounts lastObject];
NSLog(@"access to facebook account ok %@", facebookAccount.username);
NSData *videoData = [NSData dataWithContentsOfFile:[_fURL absoluteString]];
NSLog(@"%@",[_fURL absoluteString]);
NSLog(@"video size = %d", [videoData length]);
NSDictionary *params = @{
@"title": @"Me being silly",
@"description": @"Me testing the video upload to Facebook with the new system."
};
NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/me/videos"];
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodPOST
URL:requestURL
parameters:params];
[request addMultipartData:videoData
withName:@"source"
type:@"video/quicktime"
filename:[_fURL absoluteString]];
request.account = facebookAccount;
[request performRequestWithHandler:^(NSData *data, NSHTTPURLResponse *response,NSError * error){
NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"response = %@", responseString);
}];
是的,我缺少发布流权限,但我似乎无法弄清楚应将其放在哪里,整个代码位于一种方法下,当用户按下按钮时会调用该方法
这很简单。 那是我的实现:
- (void)requestAccessToFacebookAccountWithCompletionHandler:(QCFacebookCommunicatorCompletionHandler)completionHandler {
[[self accountStore] requestAccessToAccountsWithType:[self accountType] options:[self facebookAccountAccessRequestOptionsForReadStreamPermission] completion:^(BOOL accessForReadingGranted, NSError *error) {
if (accessForReadingGranted) {
[[self accountStore] requestAccessToAccountsWithType:[self accountType] options:[self facebookAccountAccessRequestOptionsForPublishStreamPermission] completion:^(BOOL accessForWrittingGranted, NSError *error) {
if (accessForWrittingGranted) {
completionHandler(YES, nil);
} else {
completionHandler(NO, [error userInfo]);
}
}];
} else {
completionHandler(NO, [error userInfo]);
}
}];
}
我只是使用辅助方法来返回带有选项的字典,其他内容与您的相似。
然后,您可以粘贴负责视频上传的代码而不是completionHandler调用,或者可以使用此实现,并且仅在completionHandler中成功== YES的情况下上传视频。
希望能帮助到你!
