以分享链接为例
调用原生app分享，如果没有原生app则调用web界面分享
FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
= [NSURL URLWithString:ShareURL];
= NSLocalizedString(@"Share_Message", nil);
FBSDKShareDialog *dialog = [[FBSDKShareDialog alloc] init];
= content;
= self;
= self;
= FBSDKShareDialogModeNative;
[dialog show];
#pragma mark - FaceBook Share Delegate
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results {
NSString *postId = results[@"postId"];
FBSDKShareDialog *dialog = (FBSDKShareDialog *)sharer;
if ( == FBSDKShareDialogModeBrowser && (postId == nil || [postId isEqualToString:@""])) {
// 如果使用webview分享的，但postId是空的，
// 这种情况是用户点击了『完成』按钮，并没有真的分享
[self showHUDWithModelText:NSLocalizedString(@"Share_canceled", nil)];
} else {
//分享成功
[self showHUDWithModelText:NSLocalizedString(@"Share_successfully", nil)];
}
}
- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error {
FBSDKShareDialog *dialog = (FBSDKShareDialog *)sharer;
if (error == nil && == FBSDKShareDialogModeNative) {
// 如果使用原生登录失败，但error为空，那是因为用户没有安装Facebook app
// 重设dialog的mode，再次弹出对话框
= FBSDKShareDialogModeBrowser;
[dialog show];
} else {
[self showHUDWithModelText:NSLocalizedString(@"Share_Failed", nil)];
}
}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer {
[self showHUDWithModelText:NSLocalizedString(@"Share_canceled", nil)];
