DLSlideView对常见的顶部Tab页点击、滑动分页做了封装。 它使用基于ViewController的container特性(而不是scrollview)来管理各个子页面,保留原始的系统消息,没有隐患。 同时内存模型更优于使用scrollview的方式,理论上可以支持无限分页。
可自定义标签栏:
使用方法:
1.初始化DLTabedSlideView
self.tabedSlideView.baseViewController = self; self.tabedSlideView.tabItemNormalColor = [UIColor blackColor]; self.tabedSlideView.tabItemSelectedColor = [UIColor colorWithRed:0.833 green:0.052 blue:0.130 alpha:1.000]; self.tabedSlideView.tabbarTrackColor = [UIColor colorWithRed:0.833 green:0.052 blue:0.130 alpha:1.000]; self.tabedSlideView.tabbarBackgroundImage = [UIImage imageNamed:@"tabbarBk"]; self.tabedSlideView.tabbarBottomSpacing = 3.0; DLTabedbarItem *item1 = [DLTabedbarItem itemWithTitle:@"最新" image:[UIImage imageNamed:@"goodsNew"] selectedImage:[UIImage imageNamed:@"goodsNew_d"]]; DLTabedbarItem *item2 = [DLTabedbarItem itemWithTitle:@"最热" image:[UIImage imageNamed:@"goodsHot"] selectedImage:[UIImage imageNamed:@"goodsHot_d"]]; DLTabedbarItem *item3 = [DLTabedbarItem itemWithTitle:@"价格" image:[UIImage imageNamed:@"goodsPrice"] selectedImage:[UIImage imageNamed:@"goodsPrice_d"]]; self.tabedSlideView.tabbarItems = @[item1, item2, item3]; [self.tabedSlideView buildTabbar]; self.tabedSlideView.selectedIndex = 0;
2.实现delegate
- (NSInteger)numberOfTabsInDLTabedSlideView:(DLTabedSlideView *)sender{ return 3; } - (UIViewController *)DLTabedSlideView:(DLTabedSlideView *)sender controllerAt:(NSInteger)index{ switch (index) { case 0: { OneViewController *ctrl = [[OneViewController alloc] init]; return ctrl; } case 1: { TwoViewController *ctrl = [[TwoViewController alloc] init]; return ctrl; } case 2: { ThreeViewController *ctrl = [[ThreeViewController alloc] init]; return ctrl; } default: return nil; } }
类似网易新闻,支持无限页面:
使用方法:
1.初始化DLCustomSlideView
DLLRUCache *cache = [[DLLRUCache alloc] initWithCount:6]; DLScrollTabbarView *tabbar = [[DLScrollTabbarView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 34)]; tabbar.tabItemNormalColor = [UIColor blackColor]; tabbar.tabItemSelectedColor = [UIColor redColor]; tabbar.tabItemNormalFontSize = 14.0f; tabbar.trackColor = [UIColor redColor]; itemArray_ = [NSMutableArray array]; DLScrollTabbarItem *item = [DLScrollTabbarItem itemWithTitle:@"推荐" width:80]; [itemArray_ addObject:item]; for (int i=0; i<10; i++) { item = [DLScrollTabbarItem itemWithTitle:[NSString stringWithFormat:@"页面%d", i+1] width:50]; [itemArray_ addObject:item]; } tabbar.tabbarItems = itemArray_; self.slideView.tabbar = tabbar; self.slideView.cache = cache; self.slideView.tabbarBottomSpacing = 5; self.slideView.baseViewController = self; [self.slideView setup]; self.slideView.selectedIndex = 0;
2.实现delegate
- (NSInteger)numberOfTabsInDLCustomSlideView:(DLCustomSlideView *)sender{ return itemArray_.count; } - (UIViewController *)DLCustomSlideView:(DLCustomSlideView *)sender controllerAt:(NSInteger)index{ PageNViewController *ctrl = [[PageNViewController alloc] init]; int32_t rgbValue = rand(); ctrl.view.backgroundColor = [UIColor colorWithRed:((rgbValue & 0xFF0000) >> 16)/255.0 green:((rgbValue & 0xFF00) >> 8)/255.0 blue:(rgbValue & 0xFF)/255.0 alpha:1.0]; ctrl.pageLabel.text = [NSString stringWithFormat:@"%ld", (long)index]; return ctrl; }
