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父类

- (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;

}
