使用 Bmob 后端云，不用自己写 API 接口，只需要定义数据表及相关字段即可实现用户注册、登录、修改用户信息功能。  
具体怎么创建应用，大家看官网介绍就行，这里简单说下数据表。

创建应用后，应用中的云数据库默认存在一个用户表`_User`，且相应的存在一些默认字段，如：帐号`username`，密码`password`，手机号`mobilePhoneNumberVer`/`mobilePhoneNumber`，邮箱`emailVerified`；我们开发者可以自定义往里添加需要的字段，如：昵称`nickName`。

代码示例  
1、注册

/// 注册
    + (void)registerWithName:(NSString *)name password:(NSString *)password parameter:(NSDictionary *)dict complete:(void (^)(BOOL success, NSError *error))complete
    {
        BmobUser *user = [[BmobUser alloc] init];
        [user setUsername:name];
        [user setPassword:password];
        [dict enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) {
            [user setObject:obj forKey:key];
        }];
        [user signUpInBackgroundWithBlock:^(BOOL isSuccessful, NSError *error) {
            if (complete) {
                complete(isSuccessful, error);
            }
        }];
    }

运行示例

[UserModel registerWithName:@"devZhang" password:@"123456" parameter:@{ @"nickName":@"番薯大佬"} complete:^(BOOL success, NSError * _Nonnull error) { 
    	NSLog(@"success %@, error = %@", @(success), error.description);
    }];
    
    ------------------------------------------------        
    success 1, error = (null)

2、登录

/// 登录
    + (void)loginWithName:(NSString *)userName password:(NSString *)password complete:(void (^)(BmobUser *user, NSError *error))complete
    { 
        [BmobUser loginWithUsernameInBackground:userName password:password block:^(BmobUser *user, NSError *error) { 
            if (complete) { 
                complete(user, error);
            }
        }];
    }

运行示例

[UserModel loginWithName:@"devZhang" password:@"123456" complete:^(BmobUser * _Nonnull user, NSError * _Nonnull error) { 
    	NSLog(@"user %@, error = %@", user, error.description);
    }];
    
    ------------------------------------------------        
    user 
    className = _User;
    username = devZhang;
    mobilePhoneNumber = (null);
    email = (null);
    objectId = 2bb9f3db62;
    createdAt = 2020-02-09 02:40:45 +0000;
    updatedAt = 2020-02-09 02:40:45 +0000;
    data = { 
        createdAt = "2020-02-09 10:40:45";
        nickName = "\U756a\U85af\U5927\U4f6c";
        username = devZhang;
    };

3、修改用户信息

/// 修改用户信息
    + (void)modifyWithParameter:(NSDictionary *)dict complete:(void (^)(BOOL success, NSError *error))complete
    { 
        BmobUser *user = UserModel.user;
        if (user == nil) { 
            if (complete) { 
                NSError *error = [NSError errorWithDomain:NSCocoaErrorDomain code:-1 userInfo:@{ @"message":@"用户不存在"}];
                complete(NO, error);
            }
            return;
        }
        [dict enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) { 
            [user setObject:obj forKey:key];
        }];
        [user updateInBackgroundWithResultBlock:^(BOOL isSuccessful, NSError *error) { 
            if (complete) { 
                complete(isSuccessful, error);
            }
        }];
    }

运行示例

[UserModel modifyWithParameter:@{ @"nickName":@"大番薯"} complete:^(BOOL success, NSError * _Nonnull error) { 
    	NSLog(@"success %@, error = %@", @(success), error.description);
    }];
        
    ------------------------------------------------    
    success 1, error = (null)

4、获取当前用户信息

/// 当前用户
    + (BmobUser *)user
    { 
        BmobUser *user = [BmobUser currentUser];
        return user;
    }

运行示例

BmobUser *user = UserModel.user;
    NSLog(@"user %@", user);
    
    ------------------------------------------------
    user 
    className = _User;
    username = devZhang;
    mobilePhoneNumber = (null);
    email = (null);
    objectId = 2bb9f3db62;
    createdAt = 2020-02-09 02:40:45 +0000;
    updatedAt = 2020-02-09 02:42:02 +0000;
    data = { 
        createdAt = "2020-02-09 10:40:45";
        nickName = "\U5927\U756a\U85af";
        updatedAt = "2020-02-09 10:42:02";
        username = devZhang;
    };
