因此,使用iOS5中新的Twitter框架,我们可以使用以下简单代码轻松发布Twitter更新:
if ([TWTweetComposeViewController canSendTweet]) {
TWTweetComposeViewController *tweetSheet = [[TWTweetComposeViewController alloc] init];
[tweetSheet setInitialText:@"Tweeting from Steamerduck :)"];
[controller presentModalViewController:tweetSheet animated:YES];
}
但是,我想在用户单击“发送到此处”后执行一些自定义代码:
在TWTweetComposeViewController发送一条推文之后,是否可以执行一些自定义代码和我自己的某些方法?
最佳答案
您可以指定一个完成处理程序,该处理程序在用户编写完该tweet之后被调用。看起来像这样(我还没有机会在设备上进行测试):
if ([TWTweetComposeViewController canSendTweet]) {
TWTweetComposeViewController *tweetSheet = [[TWTweetComposeViewController alloc] init];
[tweetSheet setInitialText:@"Tweeting from Steamerduck :)"];
// Set a completion handler to be called when the user is done
// composing their tweet
[tweetSheet setCompletionHandler:^(TWTweetComposeViewControllerResult result) {
if (result == TWTweetComposeViewControllerResultDone) {
// Tweet was sent, do something
} else if (result == TWTweetComposeViewControllerResultCancelled) {
// Do something else if the user cancelled
[controller dismissModalViewControllerAnimated:YES];
}
}];
[controller presentModalViewController:tweetSheet animated:YES];
}
