SLComposeViewController将崩溃

Question

一个奇怪的bug，我用下面的代码在facebook上分享了一些

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *slComposeViewController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

[slComposeViewController setInitialText:@"text"];
[slComposeViewController addImage:[UIImage imageNamed:@"image"]];
[self presentViewController:slComposeViewController animated:YES completion:nil];
} else {
 NSLog(@"Facebook not available");
}

如果在ios设置下没有facebook帐户，也没有facebook应用程序，上面的代码将运行良好，显示日志'Facebook不可用‘，但如果在ios设置下没有facebook帐户，并且有facebook应用程序，以上代码将崩溃。还有别的办法吗？

您可以使用FBSDK。here is the tutorial link

let content = FBSDKShareLinkContent()
            content.contentURL = NSURL(string: "http://share.html?id=\(1)&type=0")

            content.contentDescription = "here goes your description"



            content.imageURL = NSURL(string: "\(API_BASE_URL)\(primaryImagepath)")


            dialog.shareContent = content
            if  dialog.canShow() {
                dialog.show()
            }else{
                dialog.mode = .FeedBrowser
                dialog.show()
            }
