方法调用的参数太多,预期为1,有2个

Question

我TWTweetComposeViewController在我的应用程序中使用iOS 5遗留物.出于某种原因,我收到的是"Too many arguments to method call, expected 1, have 2" error."我试过在类似的问题中寻找答案,但到目前为止他们还没有帮助我.

这是代码:

TWTweetComposeViewController *tweetSheet =
                [[TWTweetComposeViewController alloc] init];
                [tweetSheet setInitialText:@"%@", [[_items objectAtIndex:indexPath.row] objectForKey:@"redirect_url"]];
                [self presentModalViewController:tweetSheet animated:YES];

有任何想法吗？提前致谢.

就像错误所说,你有太多的争论.您需要使用NSString的stringWithFormat方法来创建动态字符串:

[tweetSheet setInitialText:[NSString stringWithFormat:@"%@", [[_items objectAtIndex:indexPath.row] objectForKey:@"redirect_url"]]];
