我以前没有使用过钥匙串。
我收到了以下错误信息:
无法添加钥匙串项。错误-25299
在KeychainItemWrapper.m的304行:
// No previous item found; add the new one.
result = SecItemAdd((CFDictionaryRef)[self dictionaryToSecItemFormat:keychainItemData], NULL);
NSAssert( result == noErr, @"Couldn't add the Keychain Item." );
这是我保存的方法:
- (void) saveKey:(NSString *)key value:(NSString *)value {
KeychainItemWrapper *keyItem = [[KeychainItemWrapper alloc] initWithIdentifier:key accessGroup:nil];
[keyItem setObject:value forKey:(id)kSecValueData];
[keyItem release];
}
以下是API尝试保存的值:
<CFBasicHash 0x7231f60 [0x320d380]>{type = mutable dict, count = 5,
entries =>
2 : <CFString 0x2e6eb98 [0x320d380]>{contents = "labl"} = <CFString 0x2fb018 [0x320d380]>{contents = ""}
3 : <CFString 0x2e6efb8 [0x320d380]>{contents = "v_Data"} = <CFString 0x727de60 [0x320d380]>{contents = "dit8"}
4 : <CFString 0x2e6ebc8 [0x320d380]>{contents = "acct"} = <CFString 0x2fb018 [0x320d380]>{contents = ""}
5 : <CFString 0x2e6eb58 [0x320d380]>{contents = "desc"} = <CFString 0x2fb018 [0x320d380]>{contents = ""}
6 : <CFString 0x2e6ebe8 [0x320d380]>{contents = "gena"} = <CFString 0x2ffd08 [0x320d380]>{contents = "userCode"}
}
- (void)resetKeychainItem
方法中添加了[keychainItemData setObject:@"" forKey:(__bridge id)kSecAttrService];
时。当我读到下面user379075的回答时,我恍然大悟:如果你“重置”它,你也需要进行设置,反之亦然。 - mrd3650
