我正在制作一个要发布到 twitter 的应用程序(没有模式视图)。我对这个很陌生,Social.framework
所以我遇到了一些问题。更具体地说,我得到了错误:
Obtaining the web lock from a thread other than the main thread or the web thread. UIKit should not be called from a secondary thread.
而且我不确定是什么导致了这个错误。
我的 Twitter 方法如下所示:
- (void)postToTwitter
{
ACAccountType *twitterType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
SLRequestHandler requestHandler =
^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
if (responseData) {
NSInteger statusCode = urlResponse.statusCode;
if (statusCode >= 200 && statusCode < 300) {
NSDictionary *postResponseData =
[NSJSONSerialization JSONObjectWithData:responseData
options:NSJSONReadingMutableContainers
error:NULL];
NSLog(@"[SUCCESS!] Created Tweet with ID: %@", postResponseData[@"id_str"]);
}
else {
NSLog(@"[ERROR] Server responded: status code %d %@", statusCode,
[NSHTTPURLResponse localizedStringForStatusCode:statusCode]);
}
}
else {
NSLog(@"[ERROR] An error occurred while posting: %@", [error localizedDescription]);
}
};
ACAccountStoreRequestAccessCompletionHandler accountStoreHandler =
^(BOOL granted, NSError *error) {
if (granted) {
NSArray *accounts = [self.accountStore accountsWithAccountType:twitterType];
NSURL *url = [NSURL URLWithString:@"https://api.twitter.com"
@"/1.1/statuses/update_with_media.json"];
NSDictionary *params = @{@"status" : self.postTextField.text};
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter
requestMethod:SLRequestMethodPOST
URL:url
parameters:params];
[request setAccount:[accounts lastObject]];
[request performRequestWithHandler:requestHandler];
}
else {
NSLog(@"[ERROR] An error occurred while asking for user authorization: %@",
[error localizedDescription]);
}
};
[self.accountStore requestAccessToAccountsWithType:twitterType
options:NULL
completion:accountStoreHandler];
}
很像这里的例子:https ://dev.twitter.com/docs/ios/posting-images-using-twrequest
任何人都可以看到代码有任何问题,还是其他原因导致错误?
注意:似乎没有一个 NSLog 被调用。
