[[NSNotificationCenter

});

}

self.window = [[MBWindow
alloc] initWithFrame:[[UIScreen
mainScreen] bounds]];

获取登录 的状态

//判断是否登录
BOOL isLogin = [USER_DEFAULT
boolForKey:kIsLogin];
BOOL autoLogin = [USER_DEFAULT
boolForKey:kAutoLogin];

if (isLogin && autoLogin) {
_isLogin =
YES;
}else{
_isLogin =
NO;
}

登录成功把信息和时间存在本地

[[NSUserDefaults
standardUserDefaults] setInteger:1000
forKey:@"time"];
[[NSUserDefaults
standardUserDefaults] synchronize];
