UICKeyChainStore使用

存储密码这类敏感类会用UICKeyChainStore

1.pod 导入UICKeyChainStore库

2.导入 Security.framework库

存数据:

UICKeyChainStore *keychainStore=[UICKeyChainStore keyChainStoreWithService:@"demo"];

keychainStore[@"password"] = @"123444";

或者[keychainStore setData:@”NSData类型的“ forKey:@"password"];

取数据:

UICKeyChainStore *keychainStore1 = [UICKeyChainStore keyChainStoreWithService:@"demo"];//要跟保存时保持一致

NSString *_passWordStr = [keychainStore1 stringForKey:@"password"];//要跟保存时保持一致

或者:NSData *data = [keychain dataForKey:@"password"];
