一切正常，但是它说“ios设备”，我希望它说出实际应用程序的名称。我究竟做错了什么？
这是我的代码：
- (IBAction)doFacebook:(id)sender{
//check to see if facebook account exists
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
// Create the view controller defined in the .h file
fb=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
// make the default string
NSString *FBString= [NSString
stringWithFormat:@"%@\r via #GibberishGenerator", gibText.text];
[fb setInitialText:FBString];
// show the controller
[self presentViewController:fb animated:YES completion:nil];
}
}
