Question

我使用下面的代码在iOS上安全地存储字符串。有时SecItemAdd()然后-34018失败并返回错误代码NSMutableDictionary* query = [NSMutableDictionary dictionary]; [query setObject:(__bridge id)kSecClassGenericPassword forKey:(__bridge id)kSecClass]; [query setObject:account forKey:(__bridge id)kSecAttrAccount]; [query setObject:(__bridge id)kSecAttrAccessibleAlways forKey:(__bridge id)kSecAttrAccessible]; OSStatus error = SecItemCopyMatching((__bridge CFDictionaryRef)query, NULL); if (error == errSecSuccess) { // Do update. NSDictionary* attributesToUpdate; attributesToUpdate = [NSDictionary dictionaryWithObject:[inputString dataUsingEncoding:NSUTF8StringEncoding] forKey:(__bridge id)kSecValueData]; error = SecItemUpdate((__bridge CFDictionaryRef)query, (__bridge CFDictionaryRef)attributesToUpdate); if (error != errSecSuccess) { NBLog(@"SecItemUpdate failed: %d", (int)error); result = NO; } } else if (error == errSecItemNotFound) { // Do add. [query setObject:[inputString dataUsingEncoding:NSUTF8StringEncoding] forKey:(__bridge id)kSecValueData]; error = SecItemAdd((__bridge CFDictionaryRef)query, NULL); if (error != errSecSuccess) { NBLog(@"SecItemAdd failed: %d", (int)error); result = NO; } }。我找不到这个代码;这是什么意思？

根据{{3}}，

-34018是errSecMissingEntitlement

Internal error when a required entitlement isn't present.

对于iOS 10或更高版本，您需要一个.entitlements文件来访问钥匙串。像这样：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.keystore.access-keychain-keys</key>
    <true/>
    <key>com.apple.keystore.device</key>
    <true/>
</dict>
</plist>

SecItem metods失败了-34018
