i have followed "GenericKeychain" sample app from apple & already able to write a string into keychain & also able to read it from keychain.
我使用了苹果公司的“通用钥匙链”示例应用程序，已经能够将字符串写入钥匙链，也能够从钥匙链读取。
But i am wondering how can i store an array of string inside keychain, Is it possible ? How ?

You can only store objects of type CFDataRef (which is toll-free bridged to NSData) in a keychain.
您只能在keychain中存储CFDataRef类型的对象(这是免费的桥接到NSData)。
To store an array of strings you would typically use property list serialization:
要存储字符串数组，通常使用属性列表序列化:
NSArray *myArray = @[@"my", @"strings"];
NSData *data = [NSPropertyListSerialization dataWithPropertyList:myArray format: NSPropertyListBinaryFormat_v1_0 options:0 error:NULL];
Now you can put data into the keychain.
现在可以将数据放入密钥链中。
