iOS的FBSDKShareDialog回调 [英] FBSDKShareDialog callback for iOS

问题描述

当FBSDKShareDialog返回到您的应用程序（用户完成创建帖子）后，什么是FBSDKShareDialog的回调方法？

这是我必须创建的对话框：

   - （IBAction）post：（id）sender {
 FBSDKShareLinkContent * content = [[FBSDKShareLinkContent alloc ] 在里面]; 
 content.contentURL = [NSURL URLWithString：self.spinShareURL]; 
 content.contentDescription = @＃spin; 
 self.fromFacebook = true; 
 
 [FBSDKShareDialog showFromViewController：self withContent：content delegate：nil]; 
 
} 
  

我读到某个地方有一个回调

   - （void）dialogDidComplete：（FBSDKShareDialog *）对话框{
} 
  pre> 
 
 
但这对我来说无效。
解决方案
我在下面的页面找到了解决方案：

这是我的最终代码：
   - （IBAction）post：（id）sender { 
 FBSDKShareLinkContent * content = [[FBSDKShareLinkContent alloc] init]; 
 content.contentURL = [NSURL URLWithString：self.spinShareURL]; 
 content.contentTitle = [NSString stringWithFormat：@％@'s spin，self.username]; 
 content.contentDescription = @＃spin; 
 self.fromFacebook = true; 
 
 [FBSDKShareDialog showFromViewController：self withContent：content delegate：self]; 
 
}  - （void）sharer：（id< FBSDKSharing>）sharer didCompleteWithResults：（NSDictionary *）结果
 {
 NSLog（@从facebook post返回到应用程序 ）; 
 UIAlertView * alert = [[UIAlertView alloc] initWithTitle：nil 
 message：@发贴！ 
委托：self 
 cancelButtonTitle：nil 
 otherButtonTitles：nil]; 
 [alert show]; 
 double delayInSeconds = 1.0; 
 dispatch_time_t popTime = dispatch_time（DISPATCH_TIME_NOW，（int64_t）（delayInSeconds * NSEC_PER_SEC））; 
 dispatch_after（popTime，dispatch_get_main_queue（），^（void）{
 [alert dismissWithClickedButtonIndex：0 animated：YES]; 
}）; 
} 
 
  - （void）sharerDidCancel：（id< FBSDKSharing>）sharer 
 {
 NSLog（@cancelled！ 
 
 
  - （void）sharer：（id< FBSDKSharing>）sharer didFailWithError :( NSError *）错误
 {
 NSLog（@共享错误：％ @，错误）; 
 NSString * message = @共享问题，请再试一次！ 
 [[[UIAlertView alloc] initWithTitle：nil message：message delegate：nil cancelButtonTitle：@OKotherButtonTitles：nil] show]; 
} 
  
 
What is the callback method for FBSDKShareDialog when it returns back to your app (after the user has finished creating a post)?

This is what I have to create the dialog:
-(IBAction)post:(id)sender{
    FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
    content.contentURL = [NSURL URLWithString:self.spinShareURL];
    content.contentDescription=@"#spin";
    self.fromFacebook = true;

    [FBSDKShareDialog showFromViewController:self withContent:content delegate:nil];

}
I read somewhere that there is a callback 
-(void)dialogDidComplete:(FBSDKShareDialog *)dialog{
 }
But this didn't work for me.
解决方案
I found the solution at the following page:

http://jitu1990.blogspot.com/2015/05/share-with-facebook-from-ios-app.html

Here is my final code:
-(IBAction)post:(id)sender{
    FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
    content.contentURL = [NSURL URLWithString:self.spinShareURL];
    content.contentTitle= [NSString stringWithFormat: @"%@'s spin", self.username];
    content.contentDescription=@"#spin";
    self.fromFacebook = true;

    [FBSDKShareDialog showFromViewController:self withContent:content delegate:self];

}- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results
{
    NSLog(@"returned back to app from facebook post");
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil
                                                    message:@"Posted!"
                                                   delegate:self
                                          cancelButtonTitle:nil
                                          otherButtonTitles:nil];
    [alert show];
    double delayInSeconds = 1.0;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
        [alert dismissWithClickedButtonIndex:0 animated:YES];
    });
}

- (void)sharerDidCancel:(id<FBSDKSharing>)sharer
{
   NSLog(@"canceled!");
}

- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error
{
    NSLog(@"sharing error:%@", error);
    NSString *message = @"There was a problem sharing. Please try again!";
    [[[UIAlertView alloc] initWithTitle:nil message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
}
