SAMkeychain可以用来储存用户的隐私信息。
一：储存数据
+ (BOOL)setPasswordData:(NSData *)password forService:(NSString *)serviceName account:(NSString *)account;
+ (BOOL)setPasswordData:(NSData *)password forService:(NSString *)serviceName account:(NSString *)account error:(NSError **)error __attribute__((swift_error(none)));
+ (BOOL)setPassword:(NSString *)password forService:(NSString *)serviceName account:(NSString *)account;
+ (BOOL)setPassword:(NSString *)password forService:(NSString *)serviceName account:(NSString *)account error:(NSError **)error __attribute__((swift_error(none)));
二：获取数据
+ (NSData *)passwordDataForService:(NSString *)serviceName account:(NSString *)account;
+ (NSData *)passwordDataForService:(NSString *)serviceName account:(NSString *)account error:(NSError **)error __attribute__((swift_error(none)));
+ (NSString *)passwordForService:(NSString *)serviceName account:(NSString *)account;
+ (NSString *)passwordForService:(NSString *)serviceName account:(NSString *)accou;
三：删除数据
+ (BOOL)deletePasswordForService:(NSString *)serviceName account:(NSString *)account;
+ (BOOL)deletePasswordForService:(NSString *)serviceName account:(NSString *)account error:(NSError **)error __attribute__((swift_error(none)));
四：获取所有帐号信息
+ (NSArray<NSDictionary<NSString *, id> *> *)allAccounts;
//NSArray *allAccounts = [SAMKeychain allAccounts];
+ (NSArray<NSDictionary<NSString *, id> *> *)allAccounts:(NSError *__autoreleasing *)error __attribute__((swift_error(none)));
+ (NSArray<NSDictionary<NSString *, id> *> *)accountsForService:(NSString *)serviceName;
+ (NSArray<NSDictionary<NSString *, id> *> *)accountsForService:(NSString *)serviceName error:(NSError *__autoreleasing *)error __attribute__((swift_error(none)));
//通过下面方法可以配置筛选的信息,
- (NSArray<NSDictionary<NSString *, id> *> *)fetchAll:(NSError **)error;
