iphone - 如何将 NSUserDefaults 同步到 Twitter 消息中？

Question

有没有办法可以NSUserDefaults在消息中同步数据Twitter？

     if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {

        SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];

        SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
            if (result == SLComposeViewControllerResultCancelled) {

                NSLog(@"Cancelled");

            } else

            {
                NSLog(@"Done");
            }

            [controller dismissViewControllerAnimated:YES completion:Nil];
        };
        controller.completionHandler =myBlock;

        [controller setInitialText:@""];
        [controller addURL:[NSURL URLWithString:@""]];
        [controller addImage:[UIImage imageNamed:@""]];

        [self presentViewController:controller animated:YES completion:Nil];

    }

我需要设置初始文本来接受 nsuserdefaults，因为我有一些用户设置的借口。这是 nsuserdefaults。

 NSString *savestring =field.text;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:savestring forKey:@"savedstring"];
[defaults synchronize];

Answer 1

 [controller setInitialText:[[NSUserDefaults standardUserDefaults] valueForKey:@"savedstring"]];

如果您想要从用户默认值返回字典的字符串值，那么您可以使用 JSON 将其转换为字符串。
