我想将图像上传到 Twitter。
我把代码写成
- (void)postImage:(UIImage *)image withStatus:(NSString *)status
{
NSLog(@"Share on Twitter");
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" : status};
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter
requestMethod:SLRequestMethodPOST
URL:url
parameters:params];
NSData *imageData = UIImageJPEGRepresentation(image, 1.f);
[request addMultipartData:imageData
withName:@"media[]"
type:@"image/jpeg"
filename:@"image.jpg"];
[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];
}
我收到错误
The operation couldn’t be completed. (com.apple.accounts error 6.)
