提问by chrisjr
I am using TWTweetComposeViewControllerfor iOS 5 legacy in my app. For some reason, I am receiving a "Too many arguments to method call, expected 1, have 2" error."I have tried looking for answers in similar questions, but they haven't helped me so far.
我TWTweetComposeViewController在我的应用程序中使用iOS 5 旧版。出于某种原因，我收到了一个"Too many arguments to method call, expected 1, have 2" error."我已经尝试在类似问题中寻找答案的消息，但到目前为止他们还没有帮助我。
Here is the code:
这是代码：
TWTweetComposeViewController *tweetSheet =
[[TWTweetComposeViewController alloc] init];
[tweetSheet setInitialText:@"%@", [[_items objectAtIndex:indexPath.row] objectForKey:@"redirect_url"]];
[self presentModalViewController:tweetSheet animated:YES];
Any ideas? Thanks in advance.

Like the error says, you have too many arguments. You need to use NSString's stringWithFormat method to create your dynamic string:
就像错误所说的那样，你有太多的论点。您需要使用 NSString 的 stringWithFormat 方法来创建您的动态字符串：
[tweetSheet setInitialText:[NSString stringWithFormat:@"%@", [[_items objectAtIndex:indexPath.row] objectForKey:@"redirect_url"]]];

You need to use [NSString stringWithFormat:@"%@",object];to make a format string.
您需要使用[NSString stringWithFormat:@"%@",object];来制作格式字符串。
