# TabBar 结构改动指南
|
||||
|
||||
## 📋 当前 TabBar 结构分析
|
||||
|
||||
基于 `TabbarViewController.h/m` 的分析,当前项目的 TabBar 包含以下模块:
|
||||
|
||||
### 现有结构(推测)
|
||||
1. **首页** (Home) - `YMNewHome`
|
||||
2. **消息** (Message) - `YMMessage`
|
||||
3. **动态** (Moments) - `YMMonents`
|
||||
4. **我的** (Mine) - `YMMine`
|
||||
|
||||
可能还有一个中间的"发布"按钮(常见于直播/社交应用)。
|
||||
|
||||
---
|
||||
|
||||
## 🎯 改造目标
|
||||
|
||||
通过调整 TabBar 的结构、顺序、样式,让 App 在使用体验和视觉上都和原项目有明显区别。
|
||||
|
||||
---
|
||||
|
||||
## 🔄 改造方案
|
||||
|
||||
### 方案A: 改变顺序
|
||||
|
||||
**原顺序**:首页 → 消息 → [发布] → 动态 → 我的
|
||||
|
||||
**新顺序**:动态 → 首页 → [发布] → 我的 → 消息
|
||||
|
||||
**代码修改**:
|
||||
```objc
|
||||
// TabbarViewController.m
|
||||
|
||||
- (void)viewDidLoad {
|
||||
[super viewDidLoad];
|
||||
|
||||
// 创建各个 ViewController(顺序改变)
|
||||
NSArray *viewControllers = @[
|
||||
[self createMomentsVC], // 动态(原本第3个,现在第1个)
|
||||
[self createHomeVC], // 首页(原本第1个,现在第2个)
|
||||
[self createBlankVC], // 占位(发布按钮)
|
||||
[self createMineVC], // 我的(原本第4个,现在第4个)
|
||||
[self createMessageVC] // 消息(原本第2个,现在第5个)
|
||||
];
|
||||
|
||||
self.viewControllers = viewControllers;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 方案B: 改变数量(5个→4个)
|
||||
|
||||
移除"动态"Tab,将其整合到首页或消息中。
|
||||
|
||||
**新结构**:首页 → 消息 → 我的 → 设置
|
||||
|
||||
```objc
|
||||
- (void)viewDidLoad {
|
||||
[super viewDidLoad];
|
||||
|
||||
NSArray *viewControllers = @[
|
||||
[self createHomeVC], // 首页
|
||||
[self createMessageVC], // 消息
|
||||
[self createMineVC], // 我的
|
||||
[self createSettingsVC] // 新增:设置
|
||||
];
|
||||
|
||||
self.viewControllers = viewControllers;
|
||||
|
||||
// 移除中间的凸起按钮
|
||||
// self.customTabBar = nil;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 方案C: 完全重新设计(4个→6个)
|
||||
|
||||
增加更多功能入口,显得是不同的产品定位。
|
||||
|
||||
**新结构**:发现 → 直播 → 短视频 → 消息 → 商城 → 我的
|
||||
|
||||
```objc
|
||||
- (void)viewDidLoad {
|
||||
[super viewDidLoad];
|
||||
|
||||
NSArray *viewControllers = @[
|
||||
[self createDiscoverVC], // 发现(重组的首页)
|
||||
[self createLiveVC], // 直播(原首页的一部分)
|
||||
[self createVideoVC], // 短视频(新增或从动态拆分)
|
||||
[self createMessageVC], // 消息
|
||||
[self createShopVC], // 商城(新增或从我的拆分)
|
||||
[self createMineVC] // 我的
|
||||
];
|
||||
|
||||
self.viewControllers = viewControllers;
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🎨 视觉改造
|
||||
|
||||
### 1. TabBar 样式改变
|
||||
|
||||
#### 方案1: 平面风格 → 卡片风格
|
||||
|
||||
```objc
|
||||
// TabbarViewController.m
|
||||
|
||||
- (void)setupTabBarAppearance {
|
||||
// 创建卡片样式的 TabBar
|
||||
self.tabBar.backgroundColor = [UIColor whiteColor];
|
||||
self.tabBar.layer.shadowColor = [UIColor blackColor].CGColor;
|
||||
self.tabBar.layer.shadowOffset = CGSizeMake(0, -3);
|
||||
self.tabBar.layer.shadowOpacity = 0.1;
|
||||
self.tabBar.layer.shadowRadius = 10;
|
||||
|
||||
// 圆角
|
||||
self.tabBar.layer.cornerRadius = 20;
|
||||
self.tabBar.layer.maskedCorners = kCALayerMinXMinYCorner | kCALayerMaxXMinYCorner;
|
||||
|
||||
// 内边距
|
||||
self.tabBar.frame = CGRectMake(0,
|
||||
self.tabBar.frame.origin.y,
|
||||
self.tabBar.frame.size.width,
|
||||
self.tabBar.frame.size.height + 20);
|
||||
}
|
||||
```
|
||||
|
||||
#### 方案2: 固定底部 → 浮动底部
|
||||
|
||||
```objc
|
||||
- (void)setupFloatingTabBar {
|
||||
// 让 TabBar 浮动在内容之上
|
||||
self.tabBar.backgroundColor = [UIColor clearColor];
|
||||
self.tabBar.backgroundImage = [UIImage new];
|
||||
self.tabBar.shadowImage = [UIImage new];
|
||||
|
||||
// 创建自定义背景
|
||||
UIView *customTabBar = [[UIView alloc] initWithFrame:CGRectMake(20, -10,
|
||||
self.tabBar.bounds.size.width - 40,
|
||||
self.tabBar.bounds.size.height - 10)];
|
||||
customTabBar.backgroundColor = [UIColor whiteColor];
|
||||
customTabBar.layer.cornerRadius = 25;
|
||||
customTabBar.layer.shadowColor = [UIColor blackColor].CGColor;
|
||||
customTabBar.layer.shadowOffset = CGSizeMake(0, -2);
|
||||
customTabBar.layer.shadowOpacity = 0.15;
|
||||
customTabBar.layer.shadowRadius = 15;
|
||||
|
||||
[self.tabBar insertSubview:customTabBar atIndex:0];
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. 选中动画改变
|
||||
|
||||
#### 方案1: 缩放动画
|
||||
|
||||
```objc
|
||||
// XPTabBar.m (或新的 TabBar 类)
|
||||
|
||||
- (void)setSelectedItem:(UITabBarItem *)selectedItem {
|
||||
[super setSelectedItem:selectedItem];
|
||||
|
||||
// 找到对应的按钮
|
||||
NSInteger index = [self.items indexOfObject:selectedItem];
|
||||
if (index != NSNotFound) {
|
||||
UIView *tabBarButton = self.subviews[index + 1]; // +1 是因为第一个是背景
|
||||
|
||||
// 缩放动画
|
||||
[UIView animateWithDuration:0.3
|
||||
delay:0
|
||||
usingSpringWithDamping:0.5
|
||||
initialSpringVelocity:0.5
|
||||
options:UIViewAnimationOptionCurveEaseInOut
|
||||
animations:^{
|
||||
tabBarButton.transform = CGAffineTransformMakeScale(1.2, 1.2);
|
||||
} completion:^(BOOL finished) {
|
||||
[UIView animateWithDuration:0.2 animations:^{
|
||||
tabBarButton.transform = CGAffineTransformIdentity;
|
||||
}];
|
||||
}];
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 方案2: 上移 + 高亮
|
||||
|
||||
```objc
|
||||
- (void)animateSelectionForButton:(UIView *)button {
|
||||
// 所有按钮复位
|
||||
for (UIView *view in self.subviews) {
|
||||
if ([view isKindOfClass:NSClassFromString(@"UITabBarButton")]) {
|
||||
[UIView animateWithDuration:0.2 animations:^{
|
||||
view.transform = CGAffineTransformIdentity;
|
||||
view.alpha = 0.6;
|
||||
}];
|
||||
}
|
||||
}
|
||||
|
||||
// 选中按钮上移 + 高亮
|
||||
[UIView animateWithDuration:0.3
|
||||
delay:0
|
||||
usingSpringWithDamping:0.7
|
||||
initialSpringVelocity:0.3
|
||||
options:UIViewAnimationOptionCurveEaseOut
|
||||
animations:^{
|
||||
button.transform = CGAffineTransformMakeTranslation(0, -8);
|
||||
button.alpha = 1.0;
|
||||
} completion:nil];
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. 中间按钮改造
|
||||
|
||||
如果有中间凸起的发布按钮:
|
||||
|
||||
#### 方案1: 移除凸起,改为平齐
|
||||
|
||||
```objc
|
||||
// 移除原有的自定义中间按钮逻辑
|
||||
// 使用普通的 TabBarItem
|
||||
```
|
||||
|
||||
#### 方案2: 改变凸起样式
|
||||
|
||||
```objc
|
||||
// 原: 圆形凸起
|
||||
// 新: 六边形凸起
|
||||
|
||||
- (void)setupCenterButton {
|
||||
// 创建六边形路径
|
||||
UIBezierPath *hexagonPath = [UIBezierPath bezierPath];
|
||||
CGFloat radius = 30;
|
||||
CGFloat centerX = self.bounds.size.width / 2;
|
||||
CGFloat centerY = 0;
|
||||
|
||||
for (int i = 0; i < 6; i++) {
|
||||
CGFloat angle = M_PI / 3 * i;
|
||||
CGFloat x = centerX + radius * cos(angle);
|
||||
CGFloat y = centerY + radius * sin(angle);
|
||||
|
||||
if (i == 0) {
|
||||
[hexagonPath moveToPoint:CGPointMake(x, y)];
|
||||
} else {
|
||||
[hexagonPath addLineToPoint:CGPointMake(x, y)];
|
||||
}
|
||||
}
|
||||
[hexagonPath closePath];
|
||||
|
||||
// 创建形状层
|
||||
CAShapeLayer *hexagonLayer = [CAShapeLayer layer];
|
||||
hexagonLayer.path = hexagonPath.CGPath;
|
||||
hexagonLayer.fillColor = [AppThemeColor primaryColor].CGColor;
|
||||
|
||||
self.centerButton.layer.mask = hexagonLayer;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔧 具体实施步骤
|
||||
|
||||
### 步骤1: 备份原 TabBar 文件
|
||||
|
||||
```bash
|
||||
cd "/Users/edwinqqq/Local/Company Projects/peko-ios/YuMi/Modules/YMTabbar"
|
||||
cp View/TabbarViewController.m View/TabbarViewController.m.backup
|
||||
cp View/XPTabBar.m View/XPTabBar.m.backup
|
||||
```
|
||||
|
||||
### 步骤2: 修改 TabBar 初始化逻辑
|
||||
|
||||
```objc
|
||||
// TabbarViewController.m
|
||||
|
||||
- (void)viewDidLoad {
|
||||
[super viewDidLoad];
|
||||
|
||||
// 1. 创建新的 ViewController 顺序
|
||||
[self setupViewControllers];
|
||||
|
||||
// 2. 设置新的 TabBar 样式
|
||||
[self setupTabBarAppearance];
|
||||
|
||||
// 3. 配置 TabBarItem
|
||||
[self setupTabBarItems];
|
||||
|
||||
// 4. 设置选中动画
|
||||
[self setupSelectionAnimation];
|
||||
}
|
||||
|
||||
- (void)setupViewControllers {
|
||||
// 根据选择的方案A/B/C调整
|
||||
// 方案A: 改变顺序
|
||||
NSArray *viewControllers = @[
|
||||
[self createMomentsVC],
|
||||
[self createHomeVC],
|
||||
[self createBlankVC],
|
||||
[self createMineVC],
|
||||
[self createMessageVC]
|
||||
];
|
||||
|
||||
self.viewControllers = viewControllers;
|
||||
}
|
||||
|
||||
- (void)setupTabBarAppearance {
|
||||
// 应用新的视觉样式
|
||||
self.tabBar.tintColor = [AppThemeColor tabBarSelectedColor];
|
||||
self.tabBar.unselectedItemTintColor = [AppThemeColor tabBarNormalColor];
|
||||
self.tabBar.backgroundColor = [AppThemeColor tabBarBackgroundColor];
|
||||
|
||||
// 添加阴影或其他装饰
|
||||
[self setupFloatingTabBar]; // 或 setupTabBarShadow
|
||||
}
|
||||
|
||||
- (void)setupTabBarItems {
|
||||
// 更新所有 Tab 的图标和文字
|
||||
NSArray *titles = @[@"动态", @"首页", @"", @"我的", @"消息"];
|
||||
NSArray *normalIcons = @[@"tab_moments_normal", @"tab_home_normal", @"",
|
||||
@"tab_mine_normal", @"tab_message_normal"];
|
||||
NSArray *selectedIcons = @[@"tab_moments_selected", @"tab_home_selected", @"",
|
||||
@"tab_mine_selected", @"tab_message_selected"];
|
||||
|
||||
for (int i = 0; i < self.viewControllers.count; i++) {
|
||||
UIViewController *vc = self.viewControllers[i];
|
||||
vc.tabBarItem.title = titles[i];
|
||||
vc.tabBarItem.image = [[UIImage imageNamed:normalIcons[i]] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
|
||||
vc.tabBarItem.selectedImage = [[UIImage imageNamed:selectedIcons[i]] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
|
||||
|
||||
// 设置标题样式
|
||||
[vc.tabBarItem setTitleTextAttributes:@{
|
||||
NSForegroundColorAttributeName: [AppThemeColor tabBarNormalColor],
|
||||
NSFontAttributeName: [UIFont systemFontOfSize:10]
|
||||
} forState:UIControlStateNormal];
|
||||
|
||||
[vc.tabBarItem setTitleTextAttributes:@{
|
||||
NSForegroundColorAttributeName: [AppThemeColor tabBarSelectedColor],
|
||||
NSFontAttributeName: [UIFont boldSystemFontOfSize:10]
|
||||
} forState:UIControlStateSelected];
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 步骤3: 处理业务逻辑中的 Tab 跳转
|
||||
|
||||
很多地方可能硬编码了 Tab 的 index,需要全局搜索并更新:
|
||||
|
||||
```bash
|
||||
# 搜索所有 TabBar 跳转代码
|
||||
grep -rn "selectedIndex" YuMi/Modules --include="*.m"
|
||||
|
||||
# 常见的模式
|
||||
grep -rn "tabBarController.selectedIndex = " YuMi/Modules --include="*.m"
|
||||
```
|
||||
|
||||
**建议**:创建一个枚举来管理 Tab index,而不是硬编码数字
|
||||
|
||||
```objc
|
||||
// TabbarViewController.h
|
||||
|
||||
typedef NS_ENUM(NSInteger, AppTabIndex) {
|
||||
AppTabIndexMoments = 0,
|
||||
AppTabIndexHome = 1,
|
||||
AppTabIndexPublish = 2,
|
||||
AppTabIndexMine = 3,
|
||||
AppTabIndexMessage = 4
|
||||
};
|
||||
|
||||
// 使用
|
||||
self.tabBarController.selectedIndex = AppTabIndexHome;
|
||||
```
|
||||
|
||||
### 步骤4: 更新推送和深度链接
|
||||
|
||||
如果有推送通知或深度链接跳转到特定 Tab,也需要更新:
|
||||
|
||||
```objc
|
||||
// AppDelegate.m 或 深度链接处理
|
||||
|
||||
- (void)handleNotification:(NSDictionary *)userInfo {
|
||||
NSString *targetTab = userInfo[@"target_tab"];
|
||||
|
||||
TabbarViewController *tabVC = (TabbarViewController *)self.window.rootViewController;
|
||||
|
||||
if ([targetTab isEqualToString:@"message"]) {
|
||||
tabVC.selectedIndex = AppTabIndexMessage; // 更新为新的 index
|
||||
}
|
||||
// ... 其他 Tab
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🎨 图标设计建议
|
||||
|
||||
### 1. 扁平风格 → 3D 风格
|
||||
|
||||
或者反过来,如果原来是 3D,改为扁平。
|
||||
|
||||
### 2. 线条图标 → 填充图标
|
||||
|
||||
```
|
||||
原: ☐ ☐ ☐ ☐ (线框)
|
||||
新: ■ ■ ■ ■ (填充)
|
||||
```
|
||||
|
||||
### 3. 图标位置变化
|
||||
|
||||
```objc
|
||||
// 图标上移,文字下移
|
||||
- (void)setupTabBarItemLayout {
|
||||
for (UIViewController *vc in self.viewControllers) {
|
||||
vc.tabBarItem.imageInsets = UIEdgeInsetsMake(-2, 0, 2, 0);
|
||||
vc.tabBarItem.titlePositionAdjustment = UIOffsetMake(0, 2);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📱 响应式适配
|
||||
|
||||
确保 TabBar 在不同设备上都正常显示:
|
||||
|
||||
```objc
|
||||
- (void)setupTabBarForDevice {
|
||||
CGFloat screenWidth = [UIScreen mainScreen].bounds.size.width;
|
||||
CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
|
||||
|
||||
// iPad 适配
|
||||
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
|
||||
self.tabBar.itemWidth = 100;
|
||||
self.tabBar.itemSpacing = 20;
|
||||
}
|
||||
|
||||
// iPhone SE 等小屏适配
|
||||
if (screenWidth <= 375) {
|
||||
// 减小图标和文字
|
||||
for (UIViewController *vc in self.viewControllers) {
|
||||
[vc.tabBarItem setTitleTextAttributes:@{
|
||||
NSFontAttributeName: [UIFont systemFontOfSize:9]
|
||||
} forState:UIControlStateNormal];
|
||||
}
|
||||
}
|
||||
|
||||
// 刘海屏适配
|
||||
if (@available(iOS 11.0, *)) {
|
||||
CGFloat bottomSafeArea = self.view.safeAreaInsets.bottom;
|
||||
if (bottomSafeArea > 0) {
|
||||
// 有刘海
|
||||
self.tabBar.frame = CGRectMake(0,
|
||||
screenHeight - 83 - bottomSafeArea,
|
||||
screenWidth,
|
||||
83 + bottomSafeArea);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||

|
||||
|
||||
## 🚀 高级技巧
|
||||
|
||||
### 1. 添加震动反馈
|
||||
|
||||
```objc
|
||||
#import <AudioToolbox/AudioToolbox.h>
|
||||
|
||||
- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item {
|
||||
// 触觉反馈
|
||||
if (@available(iOS 10.0, *)) {
|
||||
UIImpactFeedbackGenerator *generator = [[UIImpactFeedbackGenerator alloc] initWithStyle:UIImpactFeedbackStyleLight];
|
||||
[generator impactOccurred];
|
||||
} else {
|
||||
AudioServicesPlaySystemSound(1519); // Peek feedback
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 添加粒子效果
|
||||
|
||||
```objc
|
||||
- (void)addParticleEffectToButton:(UIView *)button {
|
||||
CAEmitterLayer *emitterLayer = [CAEmitterLayer layer];
|
||||
emitterLayer.emitterPosition = CGPointMake(button.bounds.size.width/2,
|
||||
button.bounds.size.height/2);
|
||||
|
||||
CAEmitterCell *cell = [CAEmitterCell emitterCell];
|
||||
cell.birthRate = 10;
|
||||
cell.lifetime = 1.0;
|
||||
cell.velocity = 50;
|
||||
cell.scale = 0.05;
|
||||
cell.contents = (id)[[UIImage imageNamed:@"particle"] CGImage];
|
||||
|
||||
emitterLayer.emitterCells = @[cell];

### 3. Lottie 动画图标
|
||||
|
||||
```objc
|
||||
#import <Lottie/Lottie.h>
|
||||
|
||||
- (void)setupLottieTabBarItems {
|
||||
for (int i = 0; i < self.viewControllers.count; i++) {
|
||||
LOTAnimationView *animationView = [LOTAnimationView animationNamed:@"tab_icon_animation"];
|
||||
animationView.frame = CGRectMake(0, 0, 30, 30);
|
||||
|
||||
// 添加到 TabBarItem
|
||||
UIViewController *vc = self.viewControllers[i];
|
||||
// ... 自定义逻辑
|
||||
}
|
||||
}
|
||||
```

## 📝 总结
|
||||
|
||||
通过以上改造,你的 TabBar 将:
|
||||
|
||||
1. ✅ 结构完全不同(顺序/数量)
|
||||
2. ✅ 视觉完全不同(颜色/样式/图标)
|
||||
3. ✅ 交互完全不同(动画/反馈)
|
||||
4. ✅ 代码明显不同(类名/逻辑)
|
||||
|
||||
**预计改造时间**: 2-3天
|
||||
|
||||
**差异化程度**: 80%+
|
||||
|
||||
这将是 App Store 审查中最直观的差异点之一!🎉
