Facebook SDK和iOS
我正在尝试使用Facebook SDK发布状态。 一些用户已经使用Facebook登录。 所以我有这个代码：Facebook SDK和iOS,ios,facebook,facebook-graph-api,Ios,Facebook,Facebook Graph Api,我正在尝试使用Facebook SDK发布状态。 一些用户已经使用Facebook登录。 所以我有这个代码： if (FBSession.activeSession.isOpen) { NSLog(@"Already Open%@",[[FBSession activeSession] accessTokenData].accessToken); // NSString *tok = [[FBSession activeSession] accessTokenData].a

}
FBRequest *postRequest = [FBRequest requestForPostStatusUpdate:@"hi" ];
[postRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
// TODO: Check for success / failure here
}];
授予发布权限后。我想要一些类似于url描述的图片和标题。我就是这样做的，在我的iAction方法中： 共享图像：
UIImage *img = myImage;
FBLoginView *loginview = [[FBLoginView alloc] init];
loginview.delegate = self;
[self performPublishAction:^{
[FBRequestConnection startForUploadPhoto:img
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[self showAlert:@"Photo Post" result:result error:error];
}];
}];
NSURL *urlToShare = [NSURL URLWithString:@"http://developers.facebook.com/ios"];
FBAppCall *appCall = [FBDialogs presentShareDialogWithLink:urlToShare
name:@"Hello Facebook"
caption:nil
description:@"The 'Hello Facebook' sample application showcases simple Facebook integration."
picture:nil
clientState:nil
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if (error) {
NSLog(@"Error: %@", error.description);
} else {
NSLog(@"Success!");
}
}];
- (void) performPublishAction:(void (^)(void)) action
{
if([[FBSession activeSession]isOpen])
{
if ([FBSession.activeSession.permissions indexOfObject:@"publish_actions"] == NSNotFound) {
// if we don't already have the permission, then we request it now
[FBSession.activeSession requestNewPublishPermissions:@[@"publish_actions"]
defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
action();
}
//For this example, ignore errors (such as if user cancels).
}];
} else {
action();
}
}
else
{
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
defaultAudience:FBSessionDefaultAudienceFriends
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
if (!error && status == FBSessionStateOpen) {
}else{
NSLog(@"Session error");
[self fbResync];
[NSThread sleepForTimeInterval:0.5]; //half a second
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
defaultAudience:FBSessionDefaultAudienceFriends
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error){
}];
}
}];
}
}

}

if (fbAccounts && [fbAccounts count] > 0 && (account = [fbAccounts objectAtIndex:0])){
[accountStore renewCredentialsForAccount:account completion:^(ACAccountCredentialRenewResult renewResult, NSError *error) {
//we don't actually need to inspect renewResult or error.
if (error){
}
}];
}
}
}
也不行。我希望第一个案子能成功。有名字、标题、描述的那个。只是什么都不做。FBAppcal变量也不可用。不确定如何帮助您…请阅读以下内容：
[self performPublishAction:^{
NSString *message = [NSString stringWithFormat:@"Updating status for %@ at %@", self.loggedInUser.first_name, [NSDate date]];
[FBRequestConnection startForPostStatusUpdate:message
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[self showAlert:message result:result error:error];
self.buttonPostStatus.enabled = YES;
}];
self.buttonPostStatus.enabled = NO;
}];
