-[__NSCFArray objectForKeyedSubscript:] error?
- by jckly
I'm trying to get the data from a JSON response object in my iOS app after I log in. I keep getting this error though.
Error:
'NSInvalidArgumentException', reason: '-[__NSCFArray objectForKeyedSubscript:]: unrecognized selector sent to instance 0x8fc29b0'
Here is my code for the request, I'm using AFNetworking:
self.operation = [manager GET:urlString parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSDictionary *JSON = (NSDictionary *)responseObject;
NSDictionary *user = JSON[@"user"];
NSString *token = user[@"auth_token"];
NSString *userID = user[@"id"];
// NSString *avatarURL = user[@"avatar_url"];
// weakSelf.credentialStore.avatarURL = avatarURL;
weakSelf.credentialStore.authToken = token;
weakSelf.credentialStore.userId = userID;
weakSelf.credentialStore.username = self.usernameField.text;
weakSelf.credentialStore.password = self.passwordField.text;
[SVProgressHUD dismiss];
[self dismissViewControllerAnimated:YES completion:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if (operation.isCancelled) {
return;
}
[SVProgressHUD showErrorWithStatus:@"Login Failed"];
NSLog(@"%@", error);
}];
What the JSON response object looks like logged:
<__NSCFArray 0x8cac0b0>(
{
user = {
"auth_token" = b3a18e0fb278739649a23f0ae325fee1e29fe5d6;
email = "jack@jack.com";
id = 1;
username = jack;
};
}
)
I'm converting the array to a Dictionary using pointers like this:
NSDictionary *JSON = (NSDictionary *)responseObject;
I'm new to iOS, apologies if problem is obvious.
Thanks for any help.
