如何刪除應用程序可訪問的所有鑰匙串項目？

Question

我有我需要刪除的iOS上丟失鑰匙串項目（可能由舊版本的應用程序編寫）。有沒有簡單的方法來實現這一目標？

Answer 1

做的所有類

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文件夾中的KeyChain Access應用程序。如果啓動該應用程序並單擊「所有項目」，它應顯示您使用此特定計算機創建的所有項目。開發人員通常以com開頭。

Answer 3

由於Daij-Djan我得到這個解決方案：

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上如何刪除所有鑰匙串項可訪問的應用程序低於：

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

如果你想確保你確實刪除記錄，你可能期間之前特定種類的鑰匙串項目的發展支票號碼後，此代碼：

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

我在斯威夫特改寫Daij-Djan的答案：

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