随诊大夫3-应用介绍页面

随诊医生3---应用介绍页面

在启动MainViewController.viewDisLoad回调方法中，会调用来初始化各个Tab。其中我们将患者Tab设置为主Tab

- (void)setupSubviews {    
    _appointScheduleVCV104 = nil;
    _myPatientsVC = nil;
    _wzsChatListVCV104 = nil;
    _mineRootVC = nil;
    
    _appointScheduleVCV104 = [[AppointScheduleViewControllerV104 alloc]init];    
    _myPatientsVC = [[MyPatientsViewController alloc]init];    
    _wzsChatListVCV104 = [[WZSChatListViewControllerV104 alloc]init];    
    _mineRootVC = [[MineRootViewController alloc]init];
    //V1.1.0
    UINavigationController *nav1 = [[UINavigationController alloc]initWithRootViewController:_appointScheduleVCV104];    
    UINavigationController *nav2 = [[UINavigationController alloc]initWithRootViewController:_myPatientsVC];    
    UINavigationController *nav3 = [[UINavigationController alloc]initWithRootViewController:_wzsChatListVCV104];    
    UINavigationController *nav4 = [[UINavigationController alloc]initWithRootViewController:_mineRootVC];    
    self.viewControllers = [[NSArray alloc]initWithObjects:nav1,nav2,nav3,nav4, nil];
    // 设置Tab标签文字
    self.tabBar.tintColor = SegColor;        
    nav1.title = @"随诊";
    nav2.title = @"患者";
    nav3.title = @"消息";
    nav4.title = @"我的";    
    //患者
    UITabBarItem *tempItem = [[[self tabBar] items] objectAtIndex:0];
    [tempItem setTag:30000+0];
    [tempItem setImage:[UIImage imageNamed:@"tabbar_item1_unselected.png"]];
    [tempItem setSelectedImage:[UIImage imageNamed:@"tabbar_item1_selected.png"]];    
    //预约
    UITabBarItem *tempItem1 = [[[self tabBar] items] objectAtIndex:1];
    [tempItem1 setTag:30000+1];
    [tempItem1 setImage:[UIImage imageNamed:@"tabbar_item2_unselected.png"]];
    [tempItem1 setSelectedImage:[UIImage imageNamed:@"tabbar_item2_selected.png"]];    
    //咨询
    UITabBarItem *tempItem2 = [[[self tabBar] items] objectAtIndex:2];
    [tempItem2 setTag:30000+2];
    [tempItem2 setImage:[UIImage imageNamed:@"tabbar_item3_unselected.png"]];
    [tempItem2 setSelectedImage:[UIImage imageNamed:@"tabbar_item3_selected.png"]];    
    //我的
    UITabBarItem *tempItem3 = [[[self tabBar] items] objectAtIndex:3];
    [tempItem3 setTag:30000+3];
    [tempItem3 setImage:[UIImage imageNamed:@"tabbar_item4_unselected.png"]];
    [tempItem3 setSelectedImage:[UIImage imageNamed:@"tabbar_item4_selected.png"]];
    // 设置提示Badge
    for (int i = 0 ; i < 4 ; i++) {
        UILabel *badgeValueLab = [[UILabel alloc] init];
        badgeValueLab.backgroundColor = [UIColor redColor];
        badgeValueLab.tag = 20000 + i;
        badgeValueLab.frame = CGRectMake(i*80+55, 6, 10, 10);
        badgeValueLab.layer.cornerRadius = 5.0;
        badgeValueLab.layer.masksToBounds = YES;
        [self.tabBar addSubview:badgeValueLab];
        badgeValueLab.hidden = YES;
    }    
    [self setSelectedIndex:1]; // 设置患者为活跃Tab
}

接下来就进入了MyPatientViewController.viewDidLoad方法：

    if ([[NSUserDefaults standardUserDefaults]boolForKey:KLoginStatus]){        
        [self loginViewDismissed];
    } else {        
        [(MainViewController *)self.tabBarController showLoginView];
    }

系统先判断是否登录，如果已经登录，则显示我的患者列表等本页面功能，如果没有登录，则显示登录注册页面：

- (void)showLoginView {    
    LoginRegisterViewControllerOne *lrvc = [[LoginRegisterViewControllerOne alloc]init];
    lrvc.delegate = _myPatientsVC;
    lrvc.DoctorModel = YES;
    UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:lrvc];    
    [self presentViewController:nav animated:NO completion:nil];
}

显示登录注册页面是调用MainViewController.showLoginView方法来实现的，方法就是将LoginRegisterViewControllerOne包在UINavigationController中，然后通过MainViewController显示出来。

在LoginRegisterViewControllerOne.viewDidLoad方法中：

    //判断是否显示介绍页面
    if ([[NSUserDefaults standardUserDefaults]boolForKey:KShowIntroView]) {
        [self showIntroWithCrossDissolve];
    }

具体显示应用介绍页面，则通过开源的EAIntroView来实现，如下所示：

- (void)showIntroWithCrossDissolve{    
    EAIntroPage *page1 = [EAIntroPage page];
    EAIntroPage *page2 = [EAIntroPage page];
    EAIntroPage *page3 = [EAIntroPage page];
    EAIntroPage *page4 = [EAIntroPage page];
    EAIntroPage *page5 = [EAIntroPage page];    
    if (_DoctorModel) {
        if (DTDEVICE_IS_IPHONE5) {
            page1.titleImage = [UIImage imageNamed:@"Dintro01.png"];
            page2.titleImage = [UIImage imageNamed:@"Dintro02.png"];
            page3.titleImage = [UIImage imageNamed:@"Dintro03.png"];
            page4.titleImage = [UIImage imageNamed:@"Dintro04.png"];
            page5.titleImage = [UIImage imageNamed:@"Dintro05.png"];
        } else {
            page1.titleImage = [UIImage imageNamed:@"Dintro01_960.png"];
            page2.titleImage = [UIImage imageNamed:@"Dintro02_960.png"];
            page3.titleImage = [UIImage imageNamed:@"Dintro03_960.png"];
            page4.titleImage = [UIImage imageNamed:@"Dintro04_960.png"];
            page5.titleImage = [UIImage imageNamed:@"Dintro05_960.png"];
        }
    } else {
        if (DTDEVICE_IS_IPHONE5) {
            page1.titleImage = [UIImage imageNamed:@"Pintro01.png"];
            page2.titleImage = [UIImage imageNamed:@"Pintro02.png"];
            page3.titleImage = [UIImage imageNamed:@"Pintro03.png"];
        } else {
            page1.titleImage = [UIImage imageNamed:@"Pintro01_960.png"];
            page2.titleImage = [UIImage imageNamed:@"Pintro02_960.png"];
            page3.titleImage = [UIImage imageNamed:@"Pintro03_960.png"];
            page4.titleImage = [UIImage imageNamed:@"Pintro04_960.png"];
            page5.titleImage = [UIImage imageNamed:@"Pintro05_960.png"];
        }
    }        
    EAIntroView *intro = [[EAIntroView alloc] initWithFrame:CGRectMake(0, 0, DTSCREEN_WIDTH, DTSCREEN_HEIGHT) andPages:@[page1,page2,page3,page4,page5]];
    [intro setDelegate:self];    
    [intro showInView:self.view animateDuration:0.0];
}

- (void)introDidFinish{
    NSLog(@"Intro callback");
}

当介绍页面完成后，就会自动从本类进入登录注册页面的注册状态。
