objective-c - 如何删除应用程序可访问的所有钥匙串(keychain)项目？

Question

我需要删除 iOS 上的杂散钥匙串(keychain)项(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点？

Answer 1

对所有类(class)都这样做

Objective-C :

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);
}

swift :

let secItemClasses = [kSecClassGenericPassword, kSecClassInternetPassword, kSecClassCertificate, kSecClassKey, kSecClassIdentity]
for itemClass in secItemClasses {
    let spec: NSDictionary = [kSecClass: itemClass]
    SecItemDelete(spec)
}
