iOS开发实例之WMPageController控件制作新闻首页效果

来源:五二脚本发布时间:12-25浏览:268 次
这篇文章主要介绍iOS开发实例之WMPageController控件制作新闻首页效果,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];
}

相关设置:
