【问题描述】：

为什么下面的代码 works fine in ios6 和 not in ios7 ？我错过了ios 7的东西吗

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 区域中的这条语句NSLog(@"arrayOfAccounts %@",arrayOfAccounts); 给出了输出：

arrayOfAccounts ( )

这是在模拟器还是手机上？您是否在 iOS 7 模拟器上设置了 Twitter 帐户？
是的，我已经在模拟器和设备上进行了测试，并且我也从设置中设置了 twitter 帐户

我以前这样做是为了获取帐户数组，它确实在 ios 6 和 ios 7 上都给了我。试一试，如果它的工作。谢谢。

在你的 .h 文件中导入这些框架

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

将此 ARC 兼容代码添加到您的 .m 文件中的任何按钮操作或您想要的帐户数组中 --

  /*

// working code for ios 6 and ios 7

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

}

【解决方案2】：

试试这个（你需要请求访问帐户）

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];

}];

【讨论】：

您在设置中添加了推特帐户吗？应用是否向用户请求访问 Twitter 帐户？
是的，我已经在设置中添加了 twitter 帐户 - 但没有向用户询问权限：“AppName”想要访问 twitter 帐户
怎么强行问这个消息
accountStore requestAccessToAccountsWithType 应该请求权限。检查该应用是否存在于推特设置中推特名称下的列表中，并为此应用打开开关
requestAccessToAccountsWithType 调用会在一段时间后给出结果 - 因此帐户第一次不显示任何对象，但是当用户第二次触发此代码时，帐户数组会正确加载并显示结果
