107 | 108 | // 创建每一页对应的 controller 109 | for (int i = 0; i < titles.count; i++) { 110 | ContentViewController *controller = [[ContentViewController alloc] init]; 111 | [self addChildViewController:controller]; 112 | } 113 | 114 | CGFloat y = [UIApplication sharedApplication].statusBarFrame.size.height + self.navigationController.navigationBar.frame.size.height; 115 | CGSize size = [UIScreen mainScreen].bounds.size; 116 | 117 | // 创建对应的 DNSPageView，并设置它的 frame 118 | DNSPageView *pageView = [[DNSPageView alloc] initWithFrame:CGRectMake(0, y, size.width, size.height - y) style:style titles:titles childViewControllers:self.childViewControllers currentIndex:7]; 119 | [self.view addSubview:pageView]; 120 | ``` 121 | 122 | 123 | 124 | ### 使用 xib 或者 storyboard 初始化 125 | 126 | 在 `xib` 或者 `storyboard` 中拖出 2 个 `UIView`，让它们分别继承 `DNSPageTitleView` 和 `DNSPageContentView`，拖线到代码中 127 | 128 | ```objective-c 129 | @property (weak, nonatomic) IBOutlet DNSPageTitleView *titleView; 130 | 131 | @property (weak, nonatomic) IBOutlet DNSPageContentView *contentView; 132 | ``` 133 | 134 | 对 DNSPageTitleView 和 DNSPageContentView 进行设置 135 | 136 | ```objective-c 137 | // 创建 DNSPageStyle，设置样式 138 | DNSPageStyle *style = [[DNSPageStyle alloc] init]; 139 | style.titleViewBackgroundColor = [UIColor redColor]; 140 | style.showCoverView = YES; 141 | 142 | // 设置标题内容 143 | NSArray *titles = @[@"头条", @"视频", @"娱乐", @"要问", @"体育"]; 144 | 145 | // 设置默认的起始位置 146 | NSInteger startIndex = 2; 147 | 148 | // 创建每一页对应的 controller 149 | for (int i = 0; i < titles.count; i++) { 150 | ContentViewController *controller = [[ContentViewController alloc] init]; 151 | [self addChildViewController:controller]; 152 | } 153 | 154 | // 创建 DNSPageViewManager 来设置它们的样式和布局 155 | DNSPageViewManager *pageViewManager = [[DNSPageViewManager alloc] initWithStyle:style 156 | titles:titles 157 | childViewControllers:self.childViewControllers 158 | currentIndex:currentIndex 159 | titleView:self.titleView 160 | contentView:self.contentView]; 161 | 162 | ``` 163 | 164 | 165 | 166 | ### 使用 DNSPageViewManager 初始化 167 | 168 | 创建 DNSPageViewManager 169 | 170 | ```objective-c 171 | - (DNSPageViewManager *)pageViewManager { 172 | if (!_pageViewManager) { 173 | // 创建 DNSPageStyle，设置样式 174 | DNSPageStyle *style = [[DNSPageStyle alloc] init]; 175 | style.showBottomLine = YES; 176 | style.titleViewScrollEnabled = YES; 177 | style.titleViewBackgroundColor = [UIColor clearColor]; 178 | 179 | // 设置标题内容 180 | NSArray *titles = @[@"头条", @"视频", @"娱乐", @"要问", @"体育"]; 181 | 182 | // 创建每一页对应的 controller 183 | for (int i = 0; i < titles.count; i++) { 184 | ContentViewController *controller = [[ContentViewController alloc] init]; 185 | [self addChildViewController:controller]; 186 | } 187 | _pageViewManager = [[DNSPageViewManager alloc] initWithStyle:style titles:titles childViewControllers:self.childViewControllers]; 188 | } 189 | return _pageViewManager; 190 | } 191 | ``` 192 | 193 | 布局 titleView 和 contentView 194 | 195 | ```objective-c 196 | // 单独设置 titleView 的 frame 197 | self.navigationItem.titleView = self.pageViewManager.titleView; 198 | self.pageViewManager.titleView.frame = CGRectMake(0, 0, 180, 44); 199 | 200 | // 单独设置 contentView 的大小和位置，可以使用 autolayout 或者 frame 201 | DNSPageContentView *contentView = self.pageViewManager.contentView; 202 | [self.view addSubview:contentView]; 203 | [contentView makeConstraints:^(MASConstraintMaker *make) { 204 | make.edges.equalTo(self.view); 205 | }]; 206 | 207 | ``` 208 | 209 | 210 | 211 | ### 样式 212 | 213 | `DNSPageStyle` 中提供了常见样式的属性，可以按照不同的需求进行设置，包括可以设置初始显示的页面 214 | 215 | 216 | 217 | ### 事件回调 218 | 219 | DNSPageView 提供了常见事件监听的代理，它属于 `DNSPageTitleViewDelegate` 的中的属性 220 | 221 | ```objective-c 222 | /** 223 | DNSPageView 的事件回调，如果有需要，请让对应的 childViewController 遵守这个协议 224 | */ 225 | @protocol DNSPageEventHandlerDelegate 226 | @optional 227 | 228 | 229 | /** 230 | 重复点击 pageTitleView 后调用 231 | */ 232 | - (void)titleViewDidSelectSameTitle; 233 | 234 | 235 | /** 236 | pageContentView 的上一页消失的时候，上一页对应的 controller 调用 237 | */ 238 | - (void)contentViewDidDisappear; 239 | 240 | /** 241 | pageContentView 滚动停止的时候，当前页对应的 controller 调用 242 | */ 243 | - (void)contentViewDidEndScroll; 244 | 245 | @end 246 | ``` 247 | 248 | 249 | 250 | ### 常见问题 251 | 252 | - `style.isTitleViewScrollEnabled` 253 | 254 | 如果标签比较少，建议设置 `style.titleViewScrollEnabled = NO`，`titleView` 会固定，`style.titleMargin` 不起作用，每个标签平分整个 `titleView` 的宽度，下划线的宽度等于标签的宽度。 255 | 256 | 如果标签比较多，建议设置 `style.titleViewScrollEnabled = YES`，`titleView` 会滑动，下划线的宽度随着标签文字的宽度变化而变化 257 | 258 | - 标签下划线的宽度跟随文字的宽度 259 | 260 | 设置 `style.titleViewScrollEnabled = YES`，可以参考 demo 中的第四种样式。 261 | 262 | - 由于 `DNSPageView` 是基于 `UIScrollView` 实现，那么就无法避免它的一些特性： 263 | 264 | - 当控制器被 `UINavigationController` 管理，且 `navigationBar.isTranslucent = YES` 的时候，当前控制器的 `view` 是从 `y = 0` 开始布局的，所以为了防止部分内容被 `navigationBar` 遮挡，系统默认会给 `UIScrollView` 添加 offset。如果想取消这个特性： 265 | - iOS 11 以前，在控制器中设置 `self.automaticallyAdjustsScrollViewInsets = NO` 266 | - iOS 11 以后引入 `SafeArea` 概念，设置 `UIScrollView` 的属性 `contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever` 267 | - 其实这个效果还与 `UIViewController` 的其他属性有关系，但因为各种组合的情景过于复杂，所以不在此一一描述 268 | - `DNSPageContentView` 用 `UICollectionView` 实现，所以这个特性有机会造成 `UICollectionView` 的高度小于它的 `item` 的高度，造成奇怪的 Bug。 269 | - 以上只是可能出现的 Bug 之一，由于 `Demo` 不能覆盖所有的场景，不同的布局需求可能会引起不同的 Bug，开发者需要明确了解自己的布局需求，注意细节，了解 iOS 布局特性，并且作出对应的调整，不能完全参照 `Demo`。 270 | 271 | 272 | ## License 273 | 274 | DNSPageView-ObjC is available under the MIT license.
