iOS开发--仿新闻首页效果WMPageController的使用详解
作者:小兵快跑
这篇文章主要介绍了iOS开发--仿新闻首页效果WMPageController的使用详解,详解的介绍了iOS开发中第三方库WMPageController控件的使用方法,有需要的可以了解下。
这一篇记录的是iOS开发中第三方库WMPageController控件的使用方法,主要是用来分页显示内容的,可以通过手势滑动来切换页面,也可以通过点击标题部分来切换页面,如下图所示:
使用方法:
新建工程DemoTest1,然后通过cocoapods引入WMPageController到项目中,Podfile文件的内容如下:
platform :ios,'7.0' target 'DemoTest1' do pod 'WMPageController', '~> 1.6.4' end
方法一:
(1)创建几个ViewController继承自UIViewController测试用:
(2)打开AppDelegate.m文件,在其中加入下面一个方法:
#import "WMPageController.h" #import "OneViewController.h" #import "ViewController.h" #import "TwoViewController.h" @interface AppDelegate () @property(nonatomic,strong) WMPageController *createPages; @end @implementation AppDelegate - (WMPageController *)createPages { //WMPageController中包含的页面数组 NSArray *controllers = [NSArray arrayWithObjects:[ViewController class], [OneViewController class],[TwoViewController class], nil]; //WMPageController控件的标题数组 NSArray *titles = [NSArray arrayWithObjects:@"体育新闻", @"娱乐新闻",@"直播新闻", nil]; //用上面两个数组初始化WMPageController对象 WMPageController *pageController = [[WMPageController alloc] initWithViewControllerClasses:controllers andTheirTitles:titles]; pageController.menuViewStyle = WMMenuViewStyleLine; pageController.titleColorSelected = [UIColor whiteColor]; pageController.titleColorNormal = [UIColor colorWithRed:168.0/255.0 green:20.0/255.0 blue:4/255.0 alpha:1]; pageController.progressColor = [UIColor colorWithRed:168.0/255.0 green:20.0/255.0 blue:4/255.0 alpha:1]; // pageController.itemsWidths = @[@(70),@(100),@(70)]; // 这里可以设置不同的宽度 //设置WMPageController每个标题的宽度 pageController.menuItemWidth = 375/3; //设置WMPageController标题栏的高度 pageController.menuHeight = 35; //设置WMPageController选中的标题的颜色 pageController.titleColorSelected = [UIColor colorWithRed:200 green:0 blue:0 alpha:1]; return pageController; } - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; WMPageController *page = [self createPages]; UINavigationController *na = [[UINavigationController alloc] initWithRootViewController:page]; self.window.rootViewController = na; [self.window makeKeyAndVisible]; return YES; }
方法二:
(1)创建个ViewController继承自WMPageController
(2)编辑ViewController.m文件,代码如下:
初始化设置:
#import "TwoViewController.h" #import "OneViewController.h" #import "TableViewController.h" #import "ThreeViewController.h" @interface ThreeViewController () @property (nonatomic, strong) NSArray *titleData; @end @implementation ThreeViewController #pragma mark 标题数组 - (NSArray *)titleData { if (!_titleData) { _titleData = @[@"单曲", @"详情", @"歌词",@"歌词"]; } return _titleData; } #pragma mark 初始化代码 - (instancetype)init { if (self = [super init]) { self.titleSizeNormal = 15; self.titleSizeSelected = 15; self.menuViewStyle = WMMenuViewStyleLine; self.menuItemWidth = [UIScreen mainScreen].bounds.size.width / self.titleData.count; self.menuHeight = 50; } return self; }
WMPageController --Datasource & Delegate
#pragma mark - Datasource & Delegate #pragma mark 返回子页面的个数 - (NSInteger)numbersOfChildControllersInPageController:(WMPageController *)pageController { return self.titleData.count; } #pragma mark 返回某个index对应的页面 - (UIViewController *)pageController:(WMPageController *)pageController viewControllerAtIndex:(NSInteger)index { switch (index) { case 0:{ TwoViewController *vcClass = [[TwoViewController alloc] init]; vcClass.title = @"1"; return vcClass; } break; case 1:{ OneViewController *vcClass = [OneViewController new]; vcClass.title = @"2"; return vcClass; } break; case 2:{ TableViewController *vcClass = [TableViewController new]; vcClass.title = @"3"; return vcClass; } break; default:{ OneViewController *vcClass = [OneViewController new]; vcClass.title = @"4"; return vcClass; } break; } } #pragma mark 返回index对应的标题 - (NSString *)pageController:(WMPageController *)pageController titleAtIndex:(NSInteger)index { return self.titleData[index]; }
