Question

为什么低于代码works fine in ios6和not in ios7？我错过了ios 7的东西

ACAccountStore *account_Store = [[ACAccountStore alloc] init];
ACAccountType *account_Type = [account_Store     accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
 arrayOfAccounts = [[NSMutableArray alloc]initWithArray:[account_Store accountsWithAccountType:account_Type]];


NSLog(@"arrayOfAccounts %@",arrayOfAccounts); 


if ([arrayOfAccounts count] > 0)
{
    ACAccount *acct1;
    array = [[NSMutableArray alloc]init];

    for (int i = 0 ; i < [arrayOfAccounts count]; i++ )
    {
        acct1 = [[ACAccount alloc]init];
        acct1 = [arrayOfAccounts objectAtIndex:i];
        [array setObject:[NSString stringWithFormat:@"%@",acct1.username] atIndexedSubscript:i];
        // NSString *username = acct1.username;
        // NSLog(@"user at index %d : username %@",i,username);

    }
}

Debug区域中的这个语句NSLog(@"arrayOfAccounts %@",arrayOfAccounts);给出了输出：

arrayOfAccounts（）

我曾经这样做以获得一系列帐户，它确实给了我ios 6和ios 7。尝试一下它的工作。谢谢。

在.h文件中导入这些框架

#import <Twitter/Twitter.h>
#import <Accounts/Accounts.h>

在.m文件中添加此ARC兼容代码任何按钮操作或您想要帐户数组 -

  /*

// working code for ios 6 and ios 7

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1)
{
   // ios 6 working code
}
else

Answer 2

尝试此操作（您需要请求访问帐户）

ACAccountStore *accountStore = [[ACAccountStore alloc] init];
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[accountStore requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error){
    if (granted) {
        NSArray *accounts = [accountStore accountsWithAccountType:accountType];

}];

Twitter帐户代码列表适用于iOS 6而非iOS 7？
