我正在使用以下代码使用 iOS 5 twitter API 在用户的时间轴中发布推文
// 创建账户存储对象。ACAccountStore *accountStore = [[ACAccountStore alloc] init];
// Create an account type that ensures Twitter accounts are retrieved.
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
// Request access from the user to use their Twitter accounts.
[accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error)
{
if(granted)
{
// Get the list of Twitter accounts.
NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
// For the sake of brevity, we'll assume there is only one Twitter account present.
// You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present.
// Grab the initial Twitter account to tweet from.
ACAccount *twitterAccount = [accountsArray objectAtIndex:buttonIndex];
// Create a request, which in this example, posts a tweet to the user's timeline.
// This example uses version 1 of the Twitter API.
// This may need to be changed to whichever version is currently appropriate.
TWRequest *postRequest = [[TWRequest alloc] initWithURL:[NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"] parameters:[NSDictionary dictionaryWithObject:@"hello this is a tweet" forKey:@"status"] requestMethod:TWRequestMethodPOST];
// Set the account used to post the tweet.
[postRequest setAccount:twitterAccount];
// Perform the request created above and create a handler block to handle the response.
[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)
{
NSString *output = [NSString stringWithFormat:@"%i", [urlResponse statusCode]];
[self performSelectorOnMainThread:@selector(TweetStatus:) withObject:output waitUntilDone:NO];
}];
}
}];
我已经使用这种方法一个多月来测试应用程序，它曾经可以正常工作，没有任何问题。
几周后，它开始在以下方法中返回 403 错误。
[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)
{
NSString *output = [NSString stringWithFormat:@"%i", [urlResponse statusCode]];
[self performSelectorOnMainThread:@selector(TweetStatus:) withObject:output waitUntilDone:NO];
}];
它给出了以下错误：
Error Domain=NSURLErrorDomain Code=-1012 "The operation couldn’t be completed. (NSURLErrorDomain error -1012.)" UserInfo=0x1f8b3250 {NSErrorFailingURLKey=http://api.twitter.com/1/statuses/update.json, NSErrorFailingURLStringKey=http://api.twitter.com/1/statuses/update.json, NSUnderlyingError=0x1ed19f90 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1012
我进行了很多搜索，但找不到任何解决方案或解决此问题的真正原因。
要记住的一些注意事项可能有助于理解问题：
- 该应用程序用于测试，这意味着我们使用了 twitter 分享并与其他用户进行了很多提及。
- 共享内容并不总是相同的，因此不会出现重复问题，因为我们经常清理时间线。
谢谢
