我使用以下代码(在WWDC 2012视频中显示)：
self.accountStore = [[ACAccountStore alloc] init];
ACAccountType *facebookAccountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
[self.accountStore requestAccesstoAccountsWithType:facebookAccountType
withCompletionHandler:^(BOOL granted,NSError *e) {
if (granted)
{
NSArray *accounts = [self.accountStore
accountsWithAccountType:facebookAccountType];
self.facebookAccount = [accounts lastObject];
} else {
// Fail gracefully...
}
}];
我还在我的.plist文件中添加了NSDictionary：
所以,我的问题是我收到以下异常：
*** Terminating app due to uncaught exception 'NSinvalidargumentexception',reason: 'Access options are required for this account type.'
我尝试过这个ACAccountTypeIdentifierTwitter和ACAccountTypeIdentifierSinaWeibo.我没有收到任何例外,虽然他们总是返回授予==否
解决方法
好吧,WWDC 2012显示了一件事,但
documentation显示了另一个……他们正在使用的方法现在已被弃用：
– requestAccesstoAccountsWithType:withCompletionHandler: Deprecated in iOS 6.0
你应该做什么：
ACAccountType *facebookAccountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSDictionary *options = @{
@"ACFacebookAppIdKey" : @"123456789",@"ACFacebookPermissionsKey" : @[@"publish_stream"],@"ACFacebookAudienceKey" : ACFacebookAudienceEveryone}; // Needed only when write permissions are requested
[self.accountStore requestAccesstoAccountsWithType:facebookAccountType options:options
completion:^(BOOL granted,NSError *error) {
if (granted)
{
NSArray *accounts = [self.accountStore
accountsWithAccountType:facebookAccountType];
self.facebookAccount = [accounts lastObject];
} else {
NSLog(@"%@",error);
// Fail gracefully...
}
}];
