无法使用SLComposeViewController将图片发布到facebook？
无法使用SLComposeViewController将图片发布到facebook？
提问于 2013-02-14 13:49:25
我想把图片发布到facebook和twitter上。我可以使用twitter，但不能使用SLComposeViewController类的facebook。没有添加图片，我可以把文字和网址放到facebook上。问题是，当我使用添加图像时，我无法发布此图像以及文本和url。当我发送的时候，SLComposeViewController会显示图片，文本和网址。我有正确的appId，并且没有收到任何错误。但问题仍然存在。我不知道问题出在哪里。请帮帮我。
- (void)performFBRequestUploadForImage{
[self showListOfFaceBookAccountsFromStore];
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
SLComposeViewController *mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = @"ACtionCancelled";
break;
case SLComposeViewControllerResultDone:
output = @"Post Successfull";
[self dismissViewControllerAnimated:YES completion:nil];
break;
default:
break;
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Face Book Message" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
};
[mySLComposerSheet addImage:[UIImage imageNamed:@"images4.jpg"]];
[mySLComposerSheet setInitialText:@"I am developer."];
[mySLComposerSheet addURL:[NSURL URLWithString:@"http://stackoverflow.com/"]];
[mySLComposerSheet setCompletionHandler:completionHandler];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
}
}
- (void)showListOfFaceBookAccountsFromStore
{
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

{
NSDictionary *options = @{
@"ACFacebookAppIdKey" : myAppId,
@"ACFacebookPermissionsKey" : @[@"publish_stream"],

我在我的项目中使用了以下代码来发布图像，它工作得很好。
if([SLComposeViewController instanceMethodForSelector:@selector(isAvailableForServiceType)] != nil)
{
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
if (result == SLComposeViewControllerResultCancelled) {
NSLog(@"Cancelled");
} else
{
NSLog(@"Done");
}
[controller dismissViewControllerAnimated:YES completion:Nil];
};
controller.completionHandler =myBlock;
[controller setInitialText:@"Check out my Christmas Gift!"];
[controller addImage:@"gift.jpg"];
[self presentViewController:controller animated:YES completion:Nil];

我在互联网上查了一下，注意到最近一两天有一些关于这个问题的讨论，它们似乎与Facebook的bug有关。因此，如果您的代码成功地将消息和图片发布到Twitter，那么不用担心！你做得很对。

I have resolved through open present-view controller in navigation-bar.it may help you.
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[controller setInitialText:shareFrom];
[controller addImage:self.photoImageView.image];
[controller addURL:[NSURL URLWithString:dayCareWebsite]];
dispatch_async(dispatch_get_main_queue(), ^ {
[self.navigationController presentViewController:controller animated:YES completion:nil];
