如何删除应用程序可访问的所有钥匙串项目？

Question

我有我需要删除的iOS上丢失钥匙串项目（可能由旧版本的应用程序编写）。有没有简单的方法来实现这一目标？

Answer 1

做的所有类

NSArray *secItemClasses = @[(__bridge id)kSecClassGenericPassword, 
         (__bridge id)kSecClassInternetPassword, 
         (__bridge id)kSecClassCertificate, 
         (__bridge id)kSecClassKey, 
         (__bridge id)kSecClassIdentity]; 
for (id secItemClass in secItemClasses) { 
    NSDictionary *spec = @{(__bridge id)kSecClass: secItemClass}; 
    SecItemDelete((__bridge CFDictionaryRef)spec); 
} 

Answer 2

您可以查看Utilities文件夹中的KeyChain Access应用程序。如果启动该应用程序并单击“所有项目”，它应显示您使用此特定计算机创建的所有项目。开发人员通常以com开头。

Answer 3

由于Daij-Djan我得到这个解决方案：

for (id secclass in @[ 
    (__bridge id)kSecClassGenericPassword, 
    (__bridge id)kSecClassInternetPassword, 
    (__bridge id)kSecClassCertificate, 
    (__bridge id)kSecClassKey, 
    (__bridge id)kSecClassIdentity]) { 
    NSMutableDictionary *query = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
            secclass, (__bridge id)kSecClass, 
            nil]; 

    SecItemDelete((__bridge CFDictionaryRef)query);   
}

Xamarin的iOS版本（MonoTouch的）的accepted answer上如何删除所有钥匙串项可访问的应用程序低于：

foreach (var recordKind in new []{ 
       SecKind.GenericPassword, 
       SecKind.Certificate, 
       SecKind.Identity, 
       SecKind.InternetPassword, 
       SecKind.Key, 
      }) 
    { 
      SecRecord query = new SecRecord(recordKind); 
      SecKeyChain.Remove(query); 
    } 

如果你想确保你确实删除记录，你可能期间之前特定种类的钥匙串项目的发展支票号码后，此代码：

SecStatusCode scc; 
var records = SecKeyChain.QueryAsRecord(new SecRecord(SecKind.GenericPassword), 1000, out scc);

我在斯威夫特改写Daij-Djan的答案：

let secItemClasses = [kSecClassGenericPassword, 
    kSecClassInternetPassword, 
    kSecClassCertificate, 
    kSecClassKey, 
    kSecClassIdentity] 
for secItemClass in secItemClasses { 
    let dictionary = [kSecClass as String:secItemClass] 
    SecItemDelete(dictionary) 
}
