ios – 在Xcode中检索当前的iCloud帐户信息

OP的评论代码如下

NSURL ubiq = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];

if (ubiq) 
{ 
    NSLog(@"iCloud access at %@",ubiq.user); // TODO: Load document... 
} 
else 
{ 
    UIAlertView alert=[[UIAlertView alloc]initWith@R_944_10283@e:@"No iCloud access" message:@"Please set your iCloud account in SetTing-iCloud" delegate:nil cancelButton@R_944_10283@e:@"OK" otherButton@R_944_10283@es:nil,nil]; // [alert show]; NSLog(@"No iCloud access"); 
}

如果您知道如何显示iCloud帐户用户名请告诉我.我已经搜索了这个,但我找不到任何答案.
