QQ侧边栏效果（UIViewController添加子视图控制器）

来源：互联网发布：mac md文件阅读器编辑：程序博客网时间：2024/05/16 01:14

效果图：（菜单，出现菜单栏-_-就放了个button，再次点击菜单回来，点击橘色的button推送到一个新的界面）

思路：给UIViewController添加标签控制器，标签控制器上装两个导航控制器，点击导航控制器上左边的UIabrButtonItem改变标签控制器视图的坐标（大小），再次点击还原

（附加：点击橘色按钮，push一个页面，页面充满整个屏幕）

给UIView添加子视图控制器：

@interface ViewController () {    UINavigationController *homenav;      //导航控制器    UINavigationController *messagenav;   //导航控制器    UITabBarController *redViewController;//标签控制器    CGPoint _point; //屏幕中心点坐标}

- (void)viewDidLoad {    [super viewDidLoad];        [self menuView];    _point = self.view.center;    redViewController = [[UITabBarController alloc]init];        redViewController.view.backgroundColor = [UIColor redColor];        //更改所有导航控制器颜色    [UINavigationBar appearance].barTintColor = [UIColor greenColor];        homenav = [[UINavigationController alloc]initWithRootViewController:[[HomeViewController alloc]init]];    messagenav = [[UINavigationController alloc]initWithRootViewController:[[MessageViewController alloc]init]];    homenav.navigationBar.translucent = NO;        redViewController.view.layer.shadowOffset = CGSizeMake(-10, 0);    redViewController.view.layer.shadowColor = [UIColor blackColor].CGColor;    //默认不显示阴影，要改不透明度    redViewController.view.layer.shadowOpacity = 0.6;    redViewController.viewControllers = @[homenav,messagenav];        //添加子视图控制器    [self addChildViewController:redViewController];    //视图添加到自己的视图上面    [self.view addSubview:redViewController.view];}

#pragma mark - 菜单- (void)menuView {    UIView *meanuView = [[UIView alloc]initWithFrame:self.view.bounds];    meanuView.backgroundColor = [UIColor yellowColor];    [self.view addSubview:meanuView];        UIButton *button = [[UIButton alloc]init];    button.frame = CGRectMake(0,100, 100, 30);    button.backgroundColor = [UIColor orangeColor];        [button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];    [meanuView addSubview:button];    }- (void)buttonPressed:(UIButton *)sender {    sharedInfoCenter.showLeftMenuView = NO;    [UIView animateWithDuration:0.2 animations:^{        redViewController.view.center = _point;        redViewController.view.transform = CGAffineTransformIdentity;    }];    NSLog(@"%@",redViewController.selectedViewController);        UIViewController *detailViewController = [[UIViewController alloc]init];    detailViewController.title = redViewController.selectedViewController.title;    detailViewController.view.backgroundColor = [UIColor whiteColor];        if ([redViewController.selectedViewController isKindOfClass:[UINavigationController class]]) {        [((UINavigationController *)redViewController.selectedViewController) pushViewController:detailViewController animated:YES];    }}

baseViewController:

- (void)viewDidLoad {    [super viewDidLoad];    //自定义视图    //    UIBarButtonItem *leftItem = [UIBarButtonItem alloc]initWithCustomView:<#(UIView *)#>    _point = self.view.center;        UIBarButtonItem *leftItem  = [[UIBarButtonItem alloc]initWithTitle:@"菜单" style:UIBarButtonItemStylePlain target:self action:@selector(barButtonItem:)];    self.navigationItem.leftBarButtonItem = leftItem;}- (void)barButtonItem:(UIBarButtonItem *)sender {    //单例持有    sharedInfoCenter.showLeftMenuView = !sharedInfoCenter.showLeftMenuView;        if (sharedInfoCenter.showLeftMenuView) {        [UIView animateWithDuration:0.2 animations:^{            self.tabBarController.view.transform = CGAffineTransformMakeScale(0.8, 0.8);            self.tabBarController.view.center = CGPointMake(_point.x + 140,_point.y);        }];    }else {                [UIView animateWithDuration:0.2 animations:^{            self.tabBarController.view.transform = CGAffineTransformIdentity;            self.tabBarController.view.center = _point;        }];    }        }
