使用FBMessageDialog iphone sdk打开facebook messanger

Question

FBSDKMessageDialog * shareDialog = [[FBSDKMessageDialog alloc] init];

FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];

content.contentDescription =@"HELLO";

content.contentURL = [NSURL URLWithString:@"http://202.258.69.3"];

shareDialog.shareContent = content;
shareDialog.delegate = self;

[FBSDKMessageDialog showWithContent:content delegate:self];

It always provided me error like as following

-canOpenURL: failed for URL: "fb-messenger-api:/" - error: "(null)" description :: The operation couldn't be completed. (com.facebook.sdk.share error 202.)

Answer 1

From the error, I am guessing it is due to one of the two reasons:

1. the user was not able to get authenticated, make sure you have added the FacebookAppID key in the info.plist file
2. try including keys fbauth and fbauth2 in info.plist under the LSApplicationQueriesSchemes
