［XMPP］iOS聊天软件学习笔记［二］

今天做的不是很多，主要做了登陆界面

开发时间：五天（工作时间）

开发工具：xcode6

开发平台：iOS8

XMPP框架：XMPPFramework

git clone https://github.com/robbiehanson/XMPPFramework.git 

界面设计：使用StoryBoard 

github地址：https://github.com/hjandyz/XMPP

现阶段的样子

1.自定义导航控制器，状态栏的模式改变在xcode5以后需要配置plist文件

 [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

plist  中  View controller-based status bar appearance 设置为 NO 

2.使用单例的方法管理用户信息，下面是单例的宏

// .h

#define singleton_interface(class) + (instancetype)shared##class;

// .m

#define singleton_implementation(class) \

static class *_instance; \

\

+ (id)allocWithZone:(struct _NSZone *)zone \

{ \

    static dispatch_once_t onceToken; \

    dispatch_once(&onceToken, ^{ \

        _instance = [super allocWithZone:zone]; \

    }); \

\

    return _instance; \

} \

\

+ (instancetype)shared##class \

{ \

    if (_instance == nil) { \

        _instance = [[class alloc] init]; \

    } \

\

    return _instance; \

}

 3.登陆的方法抽成一个夫类

- (void)login

{

    //隐藏键盘

    [self.view endEditing:YES];

    //显示正在登录

    [MBProgressHUD showMessage:@"正在登录..." toView:self.view];

    AppDelegate *delegate = [UIApplication sharedApplication].delegate;

    __weak typeof (self) weekSelf = self;

    [delegate xmppUserLogin:^(XMPPResultType type) {

        [weekSelf handleResultTye:type];

    }];

}

- (void)handleResultTye:(XMPPResultType)type

{

    dispatch_async(dispatch_get_main_queue(), ^{

        [MBProgressHUD hideHUDForView:self.view animated:YES];

        switch (type) {

            case XMPPResultTypeLoginSuccess:

                [self enterToMainPage];

                break;

            case XMPPResultTypeLoginFailure:

                NSLog(@"登录失败");

                [MBProgressHUD showError:@"用户名或密码错误" toView:self.view];

                break;

            case XMPPResultTypeNetErr:

                [MBProgressHUD showError:@"网络不给力" toView:self.view];

                break;

            default:

                break;

        }

    });

}

- (void)enterToMainPage

{

    //更改为登录状态

    [HJUserInfo sharedHJUserInfo].loginStatus = YES;

    //把用户数据保存到沙盒

    [[HJUserInfo sharedHJUserInfo] saveUserInfoToSanbox];

    //隐藏模态窗口

    [self dismissViewControllerAnimated:YES completion:nil];

    NSLog(@"登录成功");

    //登录成功后到主界面

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

    //                self.window.rootViewController = storyboard.instantiateInitialViewController;

    self.view.window.rootViewController = storyboard.instantiateInitialViewController;

}
