xcode - Cómo publicar en Facebook en iOS 6 en Objective-C usando la clase ACAccountStore

ios6 frameworks

Question

Quiero saber cómo publicar un mensaje de estado en Facebook en iOS 6 usando los nuevos marcos en Xcode 4.5. ¡Gracias! :)

Answer 1

¿Y qué debo hacer cuando solo deseo recibir una alerta en caso de que la publicación sea exitosa y nada cuando el usuario canceló la publicación?

Y desafortunadamente, esto no funciona correctamente para Twitter ... Ya no descarta el TweetSheet. Aquí está mi código:

 if(NSClassFromString(@"SLComposeViewController") != nil)
{
mySLComposerSheet = [[SLComposeViewController alloc] init]; //initiate the Social Controller
mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; //Tell him with what social plattform to use it, e.g. facebook or twitter
[mySLComposerSheet setInitialText:[NSString stringWithFormat:story.title,mySLComposerSheet.serviceType]]; //the message you want to post
[mySLComposerSheet addURL:[NSURL URLWithString:story.link]];
//for more instance methodes, go here:https://developer.apple.com/library/ios/#documentation/NetworkingInternet/Reference/SLComposeViewController_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40012205
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = NSLocalizedStringFromTable(@"As it seems you didn''t want to post to Twitter", @"ATLocalizable", @"");
break;
case SLComposeViewControllerResultDone:
output = NSLocalizedStringFromTable(@"You successfully posted to Twitter", @"ATLocalizable", @"");
break;
default:
break;
} //check if everything worked properly. Give out a message on the state.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Twitter" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
}];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];

Ok chicos, así que pellizqué la publicación original, funciona para iOS 6/7. Cambiar ServiceType, Alert Title y Message for Facebook. ¡Disfrutar!

- (IBAction)tweetMessage:(id)sender {
if(![SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) //check if Facebook Account is linked
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Unable to Tweet!" message:@"Please login to Twitter in your device settings." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
return;
}
//self.mySLComposerSheet = [[SLComposeViewController alloc] init]; //initiate the Social Controller
self.mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[self.mySLComposerSheet setInitialText:[NSString stringWithFormat:@"I found this Thing, check it out at this Place:/n %@ /n", [self someplace]]];
[self.mySLComposerSheet addImage:self.photos.firstObject];
[self presentViewController:self.mySLComposerSheet animated:YES completion:nil];
//}
[self.mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = @"Action Cancelled";
break;
case SLComposeViewControllerResultDone:
output = @"Post Successfull";
break;
default:
break;
} //check if everything worked properly. Give out a message on the state.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Twitter" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
}];
}

Publicar un mensaje es bastante simple. Es casi como con el Marco de Twitter.

Primero debe importar los marcos: sociales y cuentas

#import <Social/Social.h>
#import <Accounts/Accounts.h>

En tu archivo .h:

SLComposeViewController *mySLComposerSheet;

Este código debe incluirse dentro de su acción en su archivo .m:

 if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) //check if Facebook Account is linked
{
mySLComposerSheet = [[SLComposeViewController alloc] init]; //initiate the Social Controller
mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; //Tell him with what social platform to use it, e.g. facebook or twitter
[mySLComposerSheet setInitialText:[NSString stringWithFormat:@"Test",mySLComposerSheet.serviceType]]; //the message you want to post
[mySLComposerSheet addImage:yourimage]; //an image you could post
//for more instance methods, go here: https://developer.apple.com/documentation/social/slcomposeviewcontroller#//apple_ref/doc/uid/TP40012205
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
}
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = @"Action Cancelled";
break;
case SLComposeViewControllerResultDone:
output = @"Post Successful";
break;
default:
break;
} //check if everything worked properly. Give out a message on the state.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Facebook" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
}];

Sin embargo, así es como lo uso en mi aplicación. Suave y deja que el controlador haga el trabajo duro.

- (IBAction)postToFacebook:(id)sender {
if(![SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
NSLog(@"log output of your choice here");
}
// Facebook may not be available but the SLComposeViewController will handle the error for us.
self.mySLComposerSheet = [[SLComposeViewController alloc] init];
self.mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[self.mySLComposerSheet setInitialText:[NSString stringWithFormat:@"I found this Thing, check it out at SomeWhere:/n %@ /n", [self someURLString]]];
[self.mySLComposerSheet addImage:self.photos.firstObject]; //an image you could post
[self presentViewController:self.mySLComposerSheet animated:YES completion:nil];
[self.mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = @"Action Cancelled";
break;
case SLComposeViewControllerResultDone:
output = @"Post Successfull";
break;
default:
break;
}
if (![output isEqualToString:@"Action Cancelled"]) {
// Only alert if the post was a success. Or not! Up to you.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Facebook" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
}
}];
}

- (IBAction)btn_facebook:(id)sender {
SLComposeViewController *facebookcomposer =
[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[facebookcomposer setInitialText:@"This is just a test"];
[facebookcomposer addURL:[NSURL URLWithString:@"http://www.google.com"]];
[facebookcomposer addImage:[UIImage imageNamed:@"images.jpg"]];
[self presentViewController:facebookcomposer animated:YES completion:nil];
[facebookcomposer setCompletionHandler:^(SLComposeViewControllerResult result)
{
switch (result)
{
case SLComposeViewControllerResultDone:
NSLog(@"done");
break;
case SLComposeViewControllerResultCancelled:
NSLog(@"cancelled");
break;
default:
break;
}
}];
}
- (IBAction)btn_twitter:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {
SLComposeViewController *twitter =
[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[twitter setInitialText:@"this is just a test"];
[twitter addURL:[NSURL URLWithString:@"http://www.google.com"]];
[twitter addImage:[UIImage imageNamed:@"images.jpg"]];
[self presentViewController:twitter animated:YES completion:nil];
} else {
NSLog(@"it is not configured");
}
}
